How-to: setup your multisignature Cold wallet in Bitcoin Core 0.20 (highest security setup)

Last release of Core is amazing !
The main new feature is sortedmulti descriptor. This allows you to import your multisig setup in Core almost as if it was Electrum when combine to the new PSBT export in GUI !
As it needs command line and some weird checksum, you also need to input very long command in the console and if you made a mistake, you cannot copy the last command you made. So take your time when the commands are long to check everything and don't miss anything, use copy paste before validating the long command. You only have to do this once fortunately :)
I detail here how you do it with a k of n setup, good luck:
And you are DONE ! You should get the exact same addresses than Electrum and you can created receiving addresses in Qt ! To send money, just go to the send section, use the new coin control feature and export a partially signed transaction. You can use HWI or Electrum to sign it with your hardware wallets !
Notice: You can import more or less than 2000 addresses of each type. If less, blockchain rescan is faster but you may need to redo what we have done here later when all addresses will have been used once. If more, it is the contrary.

You now have the most possibly secure setup in one software: multisig with hardware on the full node wallet. When Bitcoin Core 0.21.0 will be out, we will also have native descriptor wallet so maybe we will have HD version of this. But for now, this is the best you can do ! Enjoy :)

P.S. : if you like doing things in one shot you can do the last two steps in one big command: importmulti '[{"desc": "wsh(sortedmulti(k,[path1]xpub1.../0/*,[path2]xpub2.../0/*,...,[pathn]xpubn/0/*))#check_sum0", "timestamp": birth_timestamp, "range": [0,2000], "watchonly": true, "keypool": true}, {"desc": "wsh(sortedmulti(k,[path1]xpub1.../1/*,[path2]xpub2.../1/*,...,[pathn]xpubn/1/*))#check_sum1", "timestamp": birth_timestamp, "range": [0,2000], "watchonly": true, "internal": true}]'

IOTA funds were stolen (3.49Ti ~500k$) on 12th March 2020 after network relaunch [longread]

Hey CC comunity!
First of all, sorry for posting it a bit late I have some serious changes in my lifestyle and business due to Coronavirus situation in the world. For those who are infected I wish to get well soon and all the rest to stay safe and to stay home.
Here is my short story:On March 12th I made similar but short post regarding my stolen IOTA in the sub IOTA. First of all I met around 50% downvotes, I don’t know why but it seems that IOTA’s community don’t want to see posts regarding stolen IOTA, I got a lot of critics for using Trinity wallet instead of hardware and so on. But I see nothing strange using desktop wallet and it doesn’t matter whether it is IOTA Trinity or Bitcoin QT or Ethereum wallet unless in has strong manually typed password, VPN connection and some other security things. Or maybe IOTA’s community was afraid of unwanted bad attention during that market crash that day. So because of that experience I decided to make a post here at CC.
Some short reminder of what happened before my funds got stolen (https://status.iota.org)
Some news:https://www.coindesk.com/iota-foundation-suspends-network-probes-fund-theft-in-trinity-wallethttps://cointelegraph.com/news/iota-foundation-investigates-funds-allegedly-stolen-from-trinity-walletshttps://www.theblockcrypto.com/post/55955/iota-foundation-funds-stolen-users-of-trinity-wallet
If you don’t want to read that news here are some facts with timestamp:
February 12th 2020 - 18:55
As a precaution we ask you to keep your Trinity wallet closed for now.
February 12th 2020 - 19:20
After initial investigation we decided to turn off the Coordinator to make sure no further theft can occur until we find out the root cause of these thefts. (Lets say: “blockchain stopped”)
February 14th 2020 - 17:50
We have found the exploit.
February 15th 2020 - 00:50
After successfully identifying the attack on Trinity through a third-party integration
February 17th 2020 - 02:23
We have just released a safe version of Trinity Desktop to allow users to check their balance and transactions. This version (1.4.1) removes the vulnerability announced on 12th February 2020. (I’ve installed this particular version)
February 21st 2020 - 18:43
ACTION MAY BE REQUIRED TO PROTECT YOUR TOKENS IN TRINITY.
February 24th I left my country for some working trip
February 26th 2020 - 13:10
We are currently in the testing phase of the migration tools, once testing completes the tools will be audited by a external party. If this all goes well we are aiming to release these tools later this week.
February 29th 2020 - 19:15
The Seed Migration Tool is now available.
March 6th 2020 - 15:17
REMINDER: You have until 5PM (UTC), Saturday, 7th March to migrate your seed.
I’m still out of the country but I’m pretty sure I’m safe coz I’ve installed 1.4.1 wallet which removes the vulnerability.
March 8th 2020 - 18:15
The migration period has ended.
I got back to my country
March 10th 2020 - 16:45
We are aiming to resume value transactions around 5PM CET today.
March 10th 2020 - 18:15
The network coordinator has resumed operation. (Let’s say “blockchain restarted”)
Now my turn:

Same day I’ve made first post on reddit to get some attention to the happened situation. At the same time I’ve start to search for some technical support through over official telegram groups:
iotatangle
(https://imgur.com/McmrF3L)I’ve send a message where I’ve stated that my funds were stolen after network relaunch. Got some response from user Basti he invited me to another group with general discussion.screen shot 1 (https://imgur.com/hvDuoQA)screen shot 2 (https://imgur.com/MewdNm5)
Our short dialogue continued at the general discussion group iotacafe
(https://imgur.com/e9ErcPW) Where Basti introduced me to the IOTA Foundation member Antonio Nardella (https://imgur.com/WxZRk8N)
Before I started my conversation with Antonio I decide to get some information about him. I’ve found a Medium post with some welcoming words to Antonio Nardella.
(https://imgur.com/KK4zoOv) telegram(https://imgur.com/VquNCpi) medium
Seems legit.
Of course I couldn't be 100% sure it was him but the information he asked for wasn’t really sensitive so decided to share all I knew and all I did.
(https://imgur.com/X3Ha02Q) He also mentioned a wallet integrated service MoonPay, whether I used the wallet with this service or not and it didn’t matter if I used the service it self.
I’ve informed him that I used 1.4.1 wallet which was recommended to install on February 17th 2020(https://imgur.com/iZdNcm7)
When he gathered all the necessary information regarding loss of funds he took the time for sending this information for investigation team.
After a long awaited answer I got the same day this:
“Hello, I was informed that the loss of tokens is associated to the person/team responsible for the Trinity wallet attack via a third-party dependency from Moonpay.
As suggested on https://status.iota.org/, please file a report with the local police and to cite the following case number when doing so: LKA Berlin, Center for Cybercrime, case number: 200213-1717-i00290.”(https://imgur.com/Gov1v0i)
So, reinstalling the wallet didn't help me to avoid the loss of funds.
Well if my funds are proved to be stolen then it means - yes, I’ve used the Trinity wallet between the December 17th 2019 and the February 17th 2020. And yes, I wasn’t able to make seed transition during the given period. I was out of the country starting form Feb 24th till March 8th. I can even proove it with my border passing stamps… You know I didn’t use to take 4.5Ti with me just in case I would need an urgent seed transition. Could you imagine thousands of people with their multimillion Bitcoin holdings carrying private keys everyday with them just in case they would need seed transition… The funds were stolen not by my mistake but IOTA developers/foundation/etc (lets say IOTA team) mistake.
At the end of my story I want to take your attention to the fact that I didn’t compromise my PC neither wallet nor password nor seed. All my fault was for using the desktop wallet… How can you imagine your user without using your software/services/etc… I want to publicly call IOTA team (especially mr David Sonstebo) to cover not only those which were to happen back in the Feb 2020 but all the loses which were caused by that wallet vulnerability.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

[TUTORIAL] -- How to SAFELY Claim New RNG Coins Using Your Private Keys

[TUTORIAL] -- How to SAFELY Claim New RNG Coins Using Your Private Keys

https://preview.redd.it/u4x1o4p37zc41.png?width=700&format=png&auto=webp&s=01d1ff52c0b7fc1c9ae5bb4f161979ad1f4bb559
I’m a longtime blockchain enthusiast and developer and one of my biggest gripes about this space is how quickly every new project is widely dismissed as a “scam” or “shitcoin” by so many people before it even gets off the ground. Sure, there is a lot of uncharted territory with pirates lurking to steal your bags left and right but with a small amount of personal education you can exist safely in the world of crypto I promise! With this article I aim to help lift your knowledge a little higher while helping keep your funds a little safer!

So What Is Happening?

On Tuesday February 18, 2020 a new coin named Ring (RNG) will be minted. This coin aims to bring two unique and fresh methods of proofing to the crypto game, quite literally: Agent-Based Hive Mining (borrowed from LCC) and Proof-of-Play Mining, where literal gameplay is used to hash and reward miners! To celebrate and help spread the word, the team is giving away claims of free RNG to all holders of the following coins:
  • Litecoin Cash (LCC)
  • Bitcoin (BTC)
  • Dash (DASH)
  • Dogecoin (DOGE)
It's being touted as the world's first crypto "4-way fork" but I'd really call it more of a "4-way claim" since its a brand new chain and not based on the code of any of the rewarded coins. It's simply a clever method of allowing a wider range of coin holders a chance to participate in the launch of these exciting new features!

How Will This Process Work?

On the 18th of February, a balance snapshot will be taken of the four chains listed above. Anyone holding a balance with any of these coins at the time of the snapshot will be forever eligible to claim their RNG at any time. Because the only way to prove ownership of a crypto address is to supply the private keys, and pretty much EVERYONE will tell you to guard those things with your life, below I will outline exactly what to do so there is absolutely 0% risk of losing a single satoshi! This method will apply to ANY claim rewards of any coin in the future as well. Always practice #SafeForking!

How Do I Safely Claim My RNG?

STEP 1 -- BEFORE THE SNAPSHOT -- VERIFY ACCESS TO YOUR PRIVATE KEYS
All core wallets will allow you to export a private key of any address in your wallet but many third party services like exchanges and hot wallets do not allow access to them. In these cases you will need to send your funds out of the third party service and into some kind of personal wallet where you can reach the private keys yourself. Then just wait for the snapshot to happen…
To make things easier on yourself, you can optionally collect your original coins into as few addresses as possible BEFORE the snapshot. Doing so reduces the number of keys you will need to empty and import later. It’s just less work!
\** SNAPSHOT HAPPENS HERE... ****
STEP 2 -- ATER THE SNAPSHOT -- EMPTY ALL ADDRESSES YOU WISH TO CLAIM
After the snapshot is confirmed, withdraw all coins OUT of each of your origin coin addresses into brand new addresses leaving the original ones quite empty. This way when you import later there is NO risk of losing anything! Also know that after you import these private keys you should never use them again for safety’s sake! It’s kind of the whole reason you’re even reading this article in the first place.
STEP 3 -- EXPORT PRIVATE KEYS FOR ALL ADDRESS YOU WISH TO CLAIM
This is the most difficult part, are you ready? Once each claim address is confirmed to be EMPTY, you must obtain each one’s private keys. This will entirely depend on the wallet you use (QT example below) but for all core wallets there is generally an option for exporting private keys somewhere in there. Collect them all!
How to Export QT Wallet Private Keys:⛔️ — DISABLE INTERNET FOR SAFETY — ⛔️- Open the QT wallet client- Click on HELP in the menu bar- Click on DEBUG WINDOW- Click on the CONSOLE tab- Click inside the input box at the bottom(if your wallet is locked…)- Type: walletpassphrase [Password] 600(this unlocks your wallet for 10 minutes)- Type: dumpprivkey [Address]- Copy the output hash, paste it into a list somewhere.(repeat as needed, clear your clipboard history after)- Type: walletlock (if applicable)⚡ — RE-ENABLE YOUR INTERNET —
STEP 4 -- IMPORT ALL PRIVATE KEYS INTO RNG CORE WALLET
\** PLEASE VERIFY THAT EVERY CLAIM ADDRESS IS EMPTY BEFORE CONTINUING... ****
The final step is to simply import each of these private keys into the new Ring Core Wallet to claim your free RNG rewards. The wallet handles this part automatically and you will see your new RNG balance right away. You can find this option under the File > Import Private Keys menu.
Importing a private key is the only way to prove ownership of a crypto address so this is unavoidable if you want to claim new coins from it. The steps above will allow you to prove ownership of your snapshotted address balance plus use its empty key to then claim your new coins thus keeping your original coins completely protected in the brand new address with a new private key (which you should now also keep VERY private!)
By emptying the address before you import it’s private key you eliminate the risk of theft entirely. One cannot take from an already empty jar. It should also be noted to NEVER use the imported address again as an added safety precaution*!*
👏👏👏 DONE! ENJOY YOUR FREE MONEY! 👏👏👏

How Much RNG Will I Receive?

Litecoin Cash holders will receive the highest claim ratio (5000 LCC = 1 RNG) as the LCC team are the ones responsible for creating Ring and wanted to extend a heart-felt thank you to the LCC community for their years of support. All other coins will be based on a 1:1 ratio with the value of Bitcoin at the time of the fork. This of course means 1 BTC = 1 RNG. For DASH and DOGE, however, their BTC market prices will determine their reward ratios. (For example if DASH is trading at 0.015 BTC each, then each DASH coin will net you a reward of 0.015 RNG to match.) Of course you don't need whole coins to claim, partial decimals work just fine!

What Value Will RNG Have?

That, my friends, is entirely up to the markets. No one in the history of crypto has had a perfect track record of price predictions so I'm not even going to try here. I will say, though, having gotten to play with their Testnet a bit so far that I am very impressed with the new Proof-of-Play method and how they have initially implemented it. It bodes very good things for the future of their project and this coin so I personally would expect its value to hold and most likely rise steadily as more people become aware of this groundbreaking new tech and it's potential to expand outward!

Is Litecoin Cash Still Going To Exist?

Absolutely! At least, from what I can gather. LCC has it's own purposes and will continue to be developed on. Ring is not meant to be a replacement or upgrade of any kind to Litecoin Cash. It is an entirely different proofing algorithm and a different mission statement altogether. It's more so meant to help expose the amazing new technologies developed on the LCC blockchain to a wider audience beyond simply its own fan base. If anything it'll act a sister chain that can help expose more folks to LCC in the future!

Disclaimer

While I am a moderator for the Litecoin Cash Discord server, I am writing this from an independent point of view as an educated crypto enthusiast with a passion for helping others navigate these waters. Having been an initial forker and third party developer on top of LCC myself, I feel I have some valuable insight into the direction the team is taking and I wanted to offer some sound advice for the upcoming Ring fork before the FUD gets caked on too thick.
I know a lot of people get scared easily in crypto because of the rampant scamming that goes on but I've watched this team work their asses off for two years to get out from under the stain of Charlie Lee's very biased, uneducated "its a scam" tweet which was endlessly parroted throughout the Litecoin community with nothing but blind party loyalty and no due diligence. The LCC folks are kind, wonderful hard-working people with big hearts and ambition and they have actually developed a unique proofing methodology that is likely going to impress a lot of people!
So before you go jumping on the "it's just another shitcoin" bandwagon please stop and take a real hard look at both Litecoin Cash (LCC) and Ring (RNG): two viable projects with something to bring to the table! If nothing else, hey, just claim your new coins and dump them off for some free money. You literally cannot lose if you PRACTICE SAFE FORKING!!!
Good luck, cryptonauts!

On the 18th of February, a balance snapshot will be taken of the four chains listed above. Anyone holding a balance with any of these coins at the time of the snapshot will be forever eligible to claim their RNG at any time. Because the only way to prove ownership of a crypto address is to supply the private keys, and pretty much EVERYONE will tell you to guard those things with your life, below I will outline exactly what to do so there is absolutely 0% risk of losing a single satoshi! This method will apply to ANY claim rewards of any coin in the future as well. Always practice #SafeForking!

How Do I Safely Claim My RNG?

STEP 1 -- BEFORE THE SNAPSHOT -- VERIFY ACCESS TO YOUR PRIVATE KEYS
All core wallets will allow you to export a private key of any address in your wallet but many third party services like exchanges and hot wallets do not allow access to them. In these cases you will need to send your funds out of the third party service and into some kind of personal wallet where you can reach the private keys yourself. Then just wait for the snapshot to happen…
To make things easier on yourself, you can optionally collect your original coins into as few addresses as possible BEFORE the snapshot. Doing so reduces the number of keys you will need to empty and import later. It’s just less work!
\** SNAPSHOT HAPPENS HERE... ****
STEP 2 -- ATER THE SNAPSHOT -- EMPTY ALL ADDRESSES YOU WISH TO CLAIM
After the snapshot is confirmed, withdraw all coins OUT of each of your origin coin addresses into brand new addresses leaving the original ones quite empty. This way when you import later there is NO risk of losing anything! Also know that after you import these private keys you should never use them again for safety’s sake! It’s kind of the whole reason you’re even reading this article in the first place.
STEP 3 -- EXPORT PRIVATE KEYS FOR ALL ADDRESS YOU WISH TO CLAIM
This is the most difficult part, are you ready? Once each claim address is confirmed to be EMPTY, you must obtain each one’s private keys. This will entirely depend on the wallet you use (QT example below) but for all core wallets there is generally an option for exporting private keys somewhere in there. Collect them all!
How to Export QT Wallet Private Keys:
⛔️ — DISABLE INTERNET FOR SAFETY — ⛔️
- Open the QT wallet client
- Click on HELP in the menu bar
- Click on DEBUG WINDOW
- Click on the CONSOLE tab
- Click inside the input box at the bottom
(if your wallet is locked…)
Type: walletpassphrase [Password] 600
(this unlocks your wallet for 10 minutes)
- Type: dumpprivkey [Address]
- Copy the output hash, paste it into a list somewhere.
(repeat as needed, clear your clipboard history after)
- Type: walletlock (if applicable)
⚡ — RE-ENABLE YOUR INTERNET — ⚡
DONE!
STEP 4 -- IMPORT ALL PRIVATE KEYS INTO RNG CORE WALLET
\** PLEASE VERIFY THAT EVERY CLAIM ADDRESS IS EMPTY BEFORE CONTINUING... ****
The final step is to simply import each of these private keys into the new Ring Core Wallet to claim your free RNG rewards. The wallet handles this part automatically and you will see your new RNG balance right away. You can find this option under the File > Import Private Keys menu.
Importing a private key is the only way to prove ownership of a crypto address so this is unavoidable if you want to claim new coins from it. The steps above will allow you to prove ownership of your snapshotted address balance plus use its empty key to then claim your new coins thus keeping your original coins completely protected in the brand new address with a new private key (which you should now also keep VERY private!)
By emptying the address before you import it’s private key you eliminate the risk of theft entirely. One cannot take from an already empty jar. It should also be noted to NEVER use the imported address again as an added safety precaution*!*
👏👏👏 DONE! ENJOY YOUR FREE MONEY! 👏👏👏

How Much RNG Will I Receive?

Litecoin Cash holders will receive the highest claim ratio (5000 LCC = 1 RNG) as the LCC team are the ones responsible for creating Ring and wanted to extend a heart-felt thank you to the LCC community for their years of support. All other coins will be based on a 1:1 ratio with the value of Bitcoin at the time of the fork. This of course means 1 BTC = 1 RNG. For DASH and DOGE, however, their BTC market prices will determine their reward ratios. (For example if DASH is trading at 0.015 BTC each, then each DASH coin will net you a reward of 0.015 RNG to match.) Of course you don't need whole coins to claim, partial decimals work just fine!

What Value Will RNG Have?

That, my friends, is entirely up to the markets. No one in the history of crypto has had a perfect track record of price predictions so I'm not even going to try here. I will say, though, having gotten to play with their Testnet a bit so far that I am very impressed with the new Proof-of-Play method and how they have initially implemented it. It bodes very good things for the future of their project and this coin so I personally would expect its value to hold and most likely rise steadily as more people become aware of this groundbreaking new tech and it's potential to expand outward!

Is Litecoin Cash Still Going To Exist?

Absolutely! At least, from what I can gather. LCC has it's own purposes and will continue to be developed on. Ring is not meant to be a replacement or upgrade of any kind to Litecoin Cash. It is an entirely different proofing algorithm and a different mission statement altogether. It's more so meant to help expose the amazing new technologies developed on the LCC blockchain to a wider audience beyond simply its own fan base. If anything it'll act a sister chain that can help expose more folks to LCC in the future!

Disclaimer

While I am a moderator for the Litecoin Cash Discord server, I am writing this from an independent point of view as an educated crypto enthusiast with a passion for helping others navigate these waters. Having been an initial forker and third party developer on top of LCC myself, I feel I have some valuable insight into the direction the team is taking and I wanted to offer some sound advice for the upcoming Ring fork before the FUD gets caked on too thick.
I know a lot of people get scared easily in crypto because of the rampant scamming that goes on but I've watched this team work their asses off for two years to get out from under the stain of Charlie Lee's very biased, uneducated "its a scam" tweet which was endlessly parroted throughout the Litecoin community with nothing but blind party loyalty and no due diligence. The LCC folks are kind, wonderful hard-working people with big hearts and ambition and they have actually developed a unique proofing methodology that is likely going to impress a lot of people!
So before you go jumping on the "it's just another shitcoin" bandwagon please stop and take a real hard look at both Litecoin Cash (LCC) and Ring (RNG): two viable projects with something to bring to the table! If nothing else, hey, just claim your new coins and dump them off for some free money. You literally cannot lose if you PRACTICE SAFE FORKING!!!
Good luck, cryptonauts!

1/16/2010 *Buys 20$ worth **Forgets and loses the key. New Liberty Standard.i

Let’s say I imagined this whole thing, I like to think so anyways. I was freshman in college and finally got that financial aide. My great aunt(73) tells me to buy 20$ worth. Della was a wise woman, god rest her soul. I remember just doing it. The thing is I was frustrated at the end. I don’t remember exact details but, some things I’m sure of. Some facts are still coming back to me the more time I spend remembering. I may of google’d bitcoin and found myself at a forum. Found this guy and then proceeded to email him. To make the purchase. I had never had as much money and was looking for something to invest into.
I may 90% sure the transaction may of completed.
I remember making a password, a really long one, and changing a few letters for numbers.
Paid the nice man via PayPal,
Received the coins, I hope.
I remember multiplying the “coins” by 1 cent, one nickel, dime and so on. I actually optimistically multiplies then by 1$ and laughed.
I remember looking at, what I know now to be a Private key, and getting frustrated that that’s all I had to represent my “imaginary intangible money,” upset I took a picture and stored the camera and a paper with the password in a drawer. I never considered anything of it until the bull run of 2017. Was convinced to find the coins but really doubted that reality was ever going to manifest.
Since then I have been casually looking into it, checked the laptop but it was wiped and idk much about computers. I constantly double think myself and wether my subconscious made the memories up. I been doing more research however, the more I think about it, the more I feel like it’s possible.
Well I figured out the date my great aunt told me to buy, it was 1/15/2010... This guy gets paypal balance increased 20$ the day after. Damn, say it ain’t so.
Can I restore the memory of that old laptop and recover the wallet? There’s only one wallet at that time and it’s bitcoin qt.
First I have to get the laptop back from my sister, we aren’t on talking terms anymore. Lol
Am I just forever going to think about this without any closure? Is this what crazy feels like?! Do you ever feel like you are living a movie script?!
P.s. you should know during this time I was super stoned as I just got my first plug that had quality and expensive herb. I was certainly lit during purchase and wallet creation .archived exchange site

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:
 
The updates
 
If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.
     

Overview

 

Steps

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     

Video

This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

Extra

Backup
Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
 
 
   
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
   
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
   
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
   
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
   
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
 
   
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
   
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

All About Zcoin

All About Zcoin

https://preview.redd.it/hixbz9f3lxm31.jpg?width=1200&format=pjpg&auto=webp&s=43896de84a3693d840c84057c0314af71718f0a3
What is Zcoin?
Zcoin, also referred to as XZC or Zerocoin, is an open source decentralized cryptocurrency that provides privacy and anonymity for its users when making transactions.
To achieve its privacy and anonymity, Zcoin uses zero-knowledge proofs via the Zerocoin protocol, which is at this moment in time one of the most cited cryptography papers.
According to Wikipedia, in cryptography, a zero-knowledge proof or zero-knowledge protocol is a method in which one party proves to another party (the verifier) that a given statement is actually true.
In other words, in a transaction with Bitcoin or Ethereum or something similar, your transaction history is always linked to your coins by default, leaving you vulnerable. All it takes is one link to your personal information or IP to find out the origin of the coins.
However, when you trade with Zcoin’s Zercoin feature, your transaction history is not linked to the actual coins. Only the receiver and sender know that the funds have actually been exchanged.

How Does Zcoin Work?

Zcoin works on the Zerocoin protocol by enforcing Zero-knowledge proofs. Here are the components of Zcoin to explain how it works.
Mint: When sending a private transaction with Zcoin, all you need to do is select the number of coins you want to mint. Post that your normal Zcoin balance would reduce automatically and you will be credited with new coins and no transaction history. In essence, your old coins are burned cryptographically, which prevents anyone else from using them again and being directed to your transaction history. You get credited with new coins with no history, while the total supply is maintained.
For now, you can only mint in denominations of 1, 10, 25, 50 and 100. If you choose ‘100’ coins to be minted, for instance, you will instantly be credited with 100 new Zcoins with no history attached to them.
  • Spend: When you want to make a private transaction, you will be required to use these ‘100’ newly minted coins. From this pool of funds, you can now send any amount in any denomination to anyone anonymously because no history is attached to it.
  • Repeat: You can ‘mint’ and ‘send’ Zcoins any number of times at anytime with your privacy intact.

Zcoin’s Vision

Zcoin seeks to improve things that Bitcoin hasn’t been able to so far, some of which include fungibility, privacy and miner’s centralization.
Users of Zcoin can enjoy full fungibility and privacy along with demolishing miner’s centralization by implementing a better proof of work algorithm called MTP.
Total Zcoin supply
Only 21 million units of Zcoin will ever be produced. Currently, there are about 3.4 million units in circulation, with the rest yet to be mined.
But the total supply has increased by 388450 XZC units after a Zcoin code bug, which the team refused to roll back due to economic reasons, which is why the total supply stands at approximately 21.4 million.
Every 10 minutes, a Zcoin block is mined and 50 coins are generated, making 72,000 Zcoins per day.
Market cap of Zcoin
According to CoinMarketCap, the total circulating supply of Zcoin is 5,757,841 XZC and the current unit price is $9.6. That makes the market cap approximately $55 million*.*

How To Buy Zcoin Cryptocurrency

If you are looking to get some Zcoin, here is a list of resources where it can be bought from.
  • Atomars – Supported pairs are XZC/BTC, XZC/ETH, XZC/USDT
  • Binance - Supported pairs are XZC/BTC, XZC/ETH, XZC/BNB
  • Huobi - Supported pairs are XZC/BTC, XZC/ETH
  • Bittrex - Supported pairs are XZC/BTC
  • Cryptopia - Supported pairs are XZC/BTC, XZC/LTC, XZC/DOGE
  • CoinExchange - Supported pairs are XZC/BTC
  • LiteBit.eu - Supported pairs are XZC/EUR
Note: At the moment, buying XZC in fiat currencies such as USD, EUR, or GBP is quite difficult.

Zcash:
Zcash is a decentralized and open-source peer-to-peer cryptocurrency that provides strong privacy protections. It was created as a fork of Bitcoin and, like bitcoin, it also has a hard limit of 21 million coins. Unlike bitcoin, however, Zcash offers total privacy for its users maintaining the absolute anonymity behind each transaction along with the parties and the amounts involved in it.
PIVX:
PIVX, which stands for Private Instant Verified Transaction, is an open-source, decentralized form of digital online money that uses blockchain technology. This makes it easy to transfer all around the world in an instant with low transaction fees with market leading security & privacy. PIVX focuses on privacy, security, anonymity, and instant transactions.
Monero:
Monero is a fast, private, secure and untraceable digital currency system that uses a special kind of cryptography to keep all its transactions 100% unlinkable and untraceable. With Monero, you are your own bank. You can spend safely, knowing that others cannot see your balances or track your activity.
Some Zcoin misconceptions
There are some misconceptions regarding Zcoin:
  • Some believe that, since Zcoin has a trusted setup that allows indefinite minting of coins, it is not safe. This is untrue. Of course, to start with they had to use a trusted setup because they have an auditable total coin supply that prevents any form of cheating. This downside however, is being taken care of by removing this trusted setup in the near future and when that happens, Zcoin will be one of the serious coins to count on for privacy.
  • Zcoin has been considered as Zcash’s fork but that is also not true because Zcash is based on the Zerocash protocol whereas Zcoin was started from scratch by applying Zerocoin tech.
Now that some of the Zcoin’s misconceptions have been cleared, here’s a look into its future.

Zcoin’s Future & Roadmap

Zcoin’s future is quite promising and worth watching based on these interesting milestones on their roadmap:
  • Zcoin is the first coin to implement MTP proof of work, which makes it possible for general masses to mine Zcoin with GPUs and CPUs. MTP doesn’t allow costly ASIC-like miners to mine XZC coins.
  • Zcoin is also implementing Znodes to make their cryptocurrency more decentralized and anonymous. These Znodes will be like masternodes and facilitate anonymous transactions as making an anonymous transaction single-handedly is quite computational.
  • Znodes will be incentivized by reducing some portion of the founder’s reward. Also, the surplus funds that get generated from the founder’s reward reduction would be used for hiring new developers and increased marketing efforts.
  • Another agenda on their roadmap is to bring inbuilt Tor or some IP obfuscation mechanism that will make it completely anonymous.
  • Apart from these, some innovative and exciting things like sigma protocol, decentralized anonymous voting and Zcoin Labs are on their roadmap, making this project worth checking out.
  • Last but not least, its recent price is a good indicator of its healthy market sentiment and shows that there are people who understand this project’s worth. Just to put things into perspective – a unit of Zcoin was priced $2 in March 2017 and now it is $37*.*

Zcoin Team & Progress

Zerocoin is a cryptocurrency proposed by professor Matthew D. Green, a professor of Johns Hopkins University, and graduate students Ian Miers and Christina Garman. It was proposed as an extension to the Bitcoin protocol that would add true cryptographic anonymity to Bitcoin transactions.
Zerocoin was first implemented into a fully functional cryptocurrency and released to the public by Poramin Insom, the lead developer, as Zcoin in September 2016.
Some of the notable dev members of the team are listed below.
Poramin Insom
Founder and Core Developer
Poramin Insom created what was the world's 4th most valuable cryptocurrency in February 2014. He is also the world's first person to implement stealth addresses in QT-Wallets, improving cryptocurrency anonymity. He earned a master’s degree in Information Security from Johns Hopkins University, where he wrote a paper on a proposed practical implementation of the Zerocoin protocol.
Alexander N.
Developer
Alexander N. aka Aizensou is a full-stack developer who has experience in many programming languages (C++, C#, Python, Perl, Java etc.) and has been involved in the cryptocurrency space since 2013. He has a broad development portfolio from low level APIs in Python and C++ to Android native applications in Java. In addition to his involvement in cryptocurrencies, Alexander was doing his P.h.D. in machine learning at a German university from 2012 to 2016.
Saran Siriphantnon
Developer
Saran Siriphantnon is the CTO of Satang.co/Satoshift, a fintech company focusing on creating an open financial system for Southeast Asia. He served as President of the Computer System Administrator Group at King Mongkut's Institute of Technology Ladkrabang.
Tadhg Riordan
Solidity Developer
Tadhg Riordan is a 24 year old Software Developer from Wexford, Ireland. He recently completed his MSc from Trinity College Dublin, where he worked with Blockchain privacy mechanisms, focusing particularly on Zero-Knowledge Proofs and the Ethereum platform. He is a strong advocate for the adoption of cryptocurrency and for complete financial privacy.
Apart from these, their team comprises of other developers, community managers, support personnel and advisors who maintain the required balance.

Advisors:

Aram Jivanyan (Cryptography Advisor): Co-Founder at Skycryptor & KMSchai
Torphop Korgtadam (It Security Consultant): Senior Vice President, Head Of Internal Audit Strategy, Innovation and Decision Science at United Overseas Bank Limited
Alexander N. aka Aizensou (Advisor)

Unique/Key Features Against Its Competitors:

  • Anonymous transactions. The project establishes a notably higher level of anonymity and seeks to bypass current analysis techniques which governments use to reveal the identity of users.
  • Not subject to transaction graph analysis. Zcoin has an anonymity set that encompasses all minted coins in a particular RSA accumulator that can scale to many thousands.
  • Innovative process. Tokens are burned cryptographically and replaced with new coins without a transaction history. This actively prevents anyone else from using the tokens again and stops the public from being directed to a user's transaction history.
  • Transparency focused. Zcoin's main advantage is its auditable money supply.

Proposed Statement Of Work (SOW) For PIVX Blockchain Wallet Tutorial Campaign

Date: February 11, 2019
Client’s Name: PIVX
Project Name: PIVX Blockchain Wallet Tutorial Campaign
Representatives For Each Cryptocurrency Project: PIVX Community
Representatives For www.Cryptocurrency.Market:
Denni Lovejoy, Software Tutorial Specialist
https://twitter.com/DenniLovejoy

I. Summary

Currently there are over 2,000 cryptocurrency projects listed on coinmarketcap.com. Many of these cryptocurrency projects have their own official “decentralized wallets”, use recommended third-party wallets or are in the process of developing their wallet software.
For example, the PIVX community created the PIVX QT Wallet.
Many newcomers entering the crypto market will not be computer or software savvy and will not properly set up, protect and secure their cryptocurrency wallets. Crypto projects such as PIVX will need Blockchain Tutorials for the PIVX Wallet to help new users understand how to use the wallet correctly.
The goal of this proposal is to obtain funding to create:
  1. Create a set of PIVX tutorials to help educate the public on how to use the the PIVX wallet and PIVX Central account in a step by step user friendly way. This set of tutorials will include:

II. Introduction

My name is Denni Lovejoy, I am a Blockchain Tutorial Specialist at www.Cryptocurrency.Market and you can view the quality of my past blockchain tutorials here:
Blockchain Tutorial Playlist
Blockchain Tutorial #41 - How To Setup A PIVX Wallet
I started creating blockchain tutorials to help newbies avoid getting hacked by bad actors in the crypto community. I chose to work with Tai Zen & Leon Fu Dot Com’s www.Cryptocurrency.Market channel because they were the 1st and only channel on the internet back in early 2013 that I found to be talking about trading and investing in bitcoin and cryptocurrencies. For example, they were the only channel that I know of to recommend investing in Bitcoin, Bitcoin Cash, Ethereum, Ethereum Classic, Stratis, Monero, Decred, NXT, Antshares, etc. when everyone else was afraid to do so. These coins all turned out to be huge winners.
I learned from the www.Cryptocurrency.Market channel that the #1 most important thing in cryptocurrencies is to survive. Unfortunately, many people who have bought cryptocurrencies lost them because of a lack of security, privacy and formal education on how to use their digital wallets correctly. The lack of blockchain tutorials amongst all cryptocurrencies is why I started my Blockchain Tutorial playlist on the Cryptocurrency Market channel. I believe uneducated newbies in the crypto community who do not understand what it takes to secure, protect and use their digital wallets will mistakenly leave their crypto on exchanges which is subject to being hacked or stolen and will not back up their private keys.
I have been monitoring the digital wallet space for quite some time now and I have chosen to associate my brand/ reputation & seek funding from the PIVX community for due to the project’s a) professionalism b) software engineering/technical abilities and most importantly c) a working privacy cryptocurrency and lastly d) the PIVX team has working decentralized wallets located on https://pivx.org/wallet/.
For the above reasons and the fact that I am more comfortable working with people I have personally met in person, I RESPECTFULLY submit this formal proposal to the PIVX community to request funding for myself to create an ambitious, 3rd party, independent, unbiased blockchain tutorials to educate the public on how to use the PIVX wallet and PIVX Central account correctly.

III. Objectives

  1. In this phase, I will demonstrate how to make a PIVX Central account, show users how to upvote/ downvote and comment on the proposals.
  2. In this phase, I will provide the step by step details on how to make a PIVX Proposal.

V. Pricing & Terms

If you are interested in having me create the video tutorials mentioned in Section IV. “Blockchain Tutorial” Deliverables for your crypto project the cost will be as follows:
  1. I respectfully request $1,500 worth of PIVX for me to complete the section IV. “Blockchain Tutorial” Deliverables.
  2. The grand total cost of section IV. “Blockchain Tutorial” Deliverables = $1,550. (Includes Proposal Submission Fee)
  3. The estimated completion time for this entire proposal: 10 Hours x 4 Videos = 40 Hours x $37.5 USD/hour = $1,500 USD for Content Creation. This proposed schedule is to do this work in under 1 month allowing me to create 1 tutorial per week.
  4. Payment will be paid in PIVX (PIVX) by a PIVX Representative to me and will be processed after all 3 tutorials are accepted by the PIVX community. I will email a PIVX Representative an invoice with the details.
  5. I will include 1 revision per video.

VI. Conditions

  1. The tutorials will be hosted on the PIVX YouTube channel or any other official platform and not hosted anywhere else.

  4. PIVX will own the copyrights to the content created in this SOW and the PIVX Project has the right to use the content without asking me for permission.
  5. Videos will follow the PIVX design guidelines.
  6. Videos will be reviewed for accuracy by representatives of the PIVX community before being released to the public.
I am submitting this first draft of my proposed Statement Of Work (SOW) to invite feedback and commentary from the PIVX community.


The following are questions are for PIVX to consider and are not part of the SOW.

Statement Of Work (SOW) FAQ:
1. What is Denni Lovejoy’s big picture approach to help educate and promote PIVX to the public?
This entire SOW is based on the premise that PIVX is sponsoring me to do a series of educational/ tutorial style videos of the cryptocurrency governance coin sector.
2. Why are you taking a tutorial-based style approach to the videos?
The reason for this approach is to help viewers AVOID any mistakes they may make while going through ANY of the processes associated with using PIVX software.
3. Will you follow the PIVX design guidelines and have consistent screen-design intro/ outros?
Yes, I plan to use consistent screen-design and leverage anything additional the PIVX design and support team can offer me including intro, outros, disclaimers, ideas, etc. I will be following the guidelines found on https://github.com/PIVX-Project/Official-PIVX-Graphics.
4. Do you plan to publish the videos on the Youtube channel of your company or will they go into the official PIVX Youtube channel?
No, I do not plan to publish the videos on our 'Cryptocurrency Market' YouTube channel which has over 26,000 subscribers and over 700 videos. PIVX will have all the rights to the videos and will not be hosted elsewhere.
5. What is your target reach expectations and how do you want to keep the videos up-to-date if something changes in the GUI/software?
I do not plan on doing any advertising or marketing for the tutorials and will let the PIVX PR marketing team strategize that. I can speak with the PR team as needed, but my proposal is to create video content only suggested by the community.
I will give 1 revision per video if any of the videos need updating.
6. Did the other cryptocurrency projects you made video tutorials for also pay for their production?
No. My approach has been to create 66 blockchain tutorials for free first, to then leverage this work portfolio as my Proof-Of-Skill so that I can approach projects like PIVX with my proposal.
7. After watching your videos on youtube the production does not feel in step with our current educational videos: https://www.youtube.com/playlist?list=PLaMrpvQ0yJ_xFLGwNoDzfT6Wr0XHpyr1R
I can adapt to the current style of educational videos listed on the PIVX Class channel. The main differences I can adjust to are: a) include background music during the intro and outro b) use themed transitions and text pop ups. If this is what the community prefers, let me know. However, I can add one element to the tutorials for consideration.

Issues with bitcoin-qt

I know this is frequently posted, but I'm incensed at how absurdly slow reindexing becomes. There's got to be something wrong with the sync mechanism.
I was 100% synced a week ago on my MacBook Pro. Latest version of the client (v0.17.0.1). I rsync'd the whole bitcoin dir (blocks, chainstate, index, etc) to another disk, ran a node on another machine using that copy for a couple of hours, then I stopped the node and rsync'd back to the Mac.
Bitcoin-qt did not like the updated blockchain. The other machine didn't like its blockchain either. Oh well, I thought, maybe it didn't shutdown properly and borked the last block. I'll let it reindex, in a few minutes it'll be grand.
But no. Bitcoin-qt decided that it was time to start over from scratch, ignoring the flawless 99.999% of data on disk. Yay.
That was 10 days ago. At one point several days ago it was about 3 hours from finishing, with a progress of around 19% per hour. A day later progress was at 0.25%. This can't be right, I thought, maybe there's a bug, a memory leak or something. I'll shut it down and restart it. Of course it's going to restart from where it left, right? Right?
No. It started from 0% again.
Several days later, it's at 0.14% and predicting it'll finish sometime next week. CPU is 96% idle, RAM is at 25%, bandwidth is 120 Mb/s and the disk is used by bitcoin-qt and nothing else. It's the only thing running on this Mac and has been for the past two weeks. NOTHING is different between 19% and 0.14% in terms of bandwidth, CPU, RAM, or disk I/O. This very machine, under the exact same conditions, was able to process 19% of the blockchain in one hour.
In the meantime, I can't move my BTC because my wallet, which has all the blocks including the ones containing the transactions with my BTC in them, doesn't believe the blocks are there.
Bitcoin-qt is broken in more ways than one. First, something is causing this absurd variation in performance. Second, it's not saving state, which is particularly painful when it takes ages to get to the end to the blockchain. Is state only kept in RAM? I've seen other threads suggesting a change in the config (dbcache seems to be the main one), but I can't just change the setting without restarting, and restarting is not an option because I'll lose everything again.
Sorry, this is extremely frustrating. I'm thinking of extracting the private key and abandoning the idea of running my own wallet. It's unusable.

Archive link
15 In January 2017, someone paid 0.23 cents for 1 transaction. As of December 2017, fees have peaked $40.
16 Told to kill yourself by Bitcoin for cashing out
17 Bitcoin is a captured system
18 Bot attack against bitcoin was allegedly perpetrated by its own moderator and Blockstream’s Greg Maxwell
19 Remember: Bitcoin Cash is solving a problem Core has failed to solve for 6 years. It is urgently needed as a technical solution, and has nothing to do with "Roger" or "Jihan".
20 Bitcoin Cash has got nothing new.
21 How the Bilderberg Group, the Federal Reserve central bank, and MasterCard took over Bitcoin BTC
More evidence
22 Even Core developers used to support 8-100MB blocks before they work for the Bankers
Proof
23 /Bitcoin loves to call Bitcoin Cash "ChinaCoin", but do they realize that over 70% of BTC hashrate comes from China?
24 /bitcoin for years: No altcoin discussion, have a ban! /bitcoin now: use Litecoin if you actually need to transact!
25 First, they said they want BCH on coinbase so they could dump it. Now they are crying about it because it's pumping.
26 Luke-Jr thinks reducing the blocksize will reduce the fees..
27 Core: Bitcoin isn't for the poor. Bitcoin Cash: we'll take them. Our fees are less than a cent. Core: BCash must die!
28 How The Banks Bought Bitcoin. The Lightning Network
29 Big Blocks Can Scale, But Will It Centralize Bitcoin?
30 "Fees will drop when everyone uses Lightning Networks" is the new "Fees will drop when SegWit is activated"
31 Adam Back let it slip he hires full-time teams of social media shills/trolls
32 The bitcoin civil war is not about block size; it's about freedom vs. authoritarianism
33 Why BCH is the real Bitcoin
34 We don't need larger blocks, since lightning will come someday™, the same way we don't need cars or planes since teleporters will come someday™
35 We don't need larger blocks, since lightning will come someday™, the same way we don't need cars or planes since teleporters will come someday™
36 Facts about Adam Back (Bitcoin/Blockstream CEO) you heard it right, he himself thinks he is in charge of Bitcoin.
37 A explaination why Core's vision is different from the real Bitcoin vision
38 The dangerously shifted incentives of SegWit
39 Lighting Network was supposed to be released in 2016
40 You can now store a year's worth of continuously full 8MB blocks for the cost of a single BTC transaction
41 They say we are trying to Kill Bitcoin. No, we are not. We are trying to save it, and make it usable for everyone, and everything. Not tomorrow. Not 6 months from now, Not 18 Months from now. NOW. That's what's going on Here.
42 Miners that want to pull out daily have to switch to BCH due to the fees
43 At $25 #BTC tx fees, if miners want to withdraw their revenue daily, they require a minimum of $140,000 worth of mining hardware to reduce the tx fee to less than 1% of their outgoings. At a $100 tx fee it requires min $560,000. Which is the centralising coin again?
44 Core developer : Bitcoin fees too high? You have invested in early tech! Have faith. Give us time.
45 A redditor even predicted the /bitcoin front page
46 Elizabeth Stark of Lightning Labs admits that a hostile actor can steal funds in LN unless you broadcast a transaction on-chain with a cryptographic proof that recovers the funds. This means LN won't work without a block size limit increase. @8min17s
47 /bitcoin is in uproar about Coinbase not implementing Segwit -> mempool mooning is single handedly Coinbase' fault. So all it takes to bring bitcoin to its knees is a single corporate entity not implementing segwit? Me thinks its not Coinbase there's something wrong with.
48 /bitcoin for years: No altcoin discussion, have a ban! /bitcoin now: use Litecoin if you actually need to transact!
49 $BCH has been attacked in every way possible since it's creation. Exchanges listing it with deceiving names and abbreviations; being dumped by bitcoin holders for over 6 months; and it still managed to close every month positively, while adding numerous new wallet/exchange pairs
50 theymos claims that the whitepaper is a historical artifact not worthy of being on the sidebar of bitcoin
51 Even a Bitcoin conference can't use Bitcoin because of it's high fees
52 185% Growth in Active Addresses for BCH in 1 month, 125% for ETH, -5% for BTC
53 Shapeshift: "Sub-$100 fees unadvisable on BTC." Core supporters: "Implement Segwit already!" Shapeshift: "We did. We're the biggest user of Segwit."
54 How btc and Bitcoin see each other
55 Man who vandalized Bitmain's office hired by Blockstream
56 Bitcoin Cash vs Bitcoin Core compared. Just the facts
57 It was obvious from the very beginning that #Bitcoin transactions were meant to be as cheap as possible. Bitcoin Core has destroyed Bitcoin's usefulness as money by creating a system where $30 fees are celebrated. - @Bitcoin
58 User explains why Core's vision is not the real Bitcoin vision
59 Fake Tweet from the president bashes BCH on /bitcoin front page. Calling it exactly what it is will get you banned.
60 A public appeal to Michael Marquardt the original Theymos.
61 Now they are angry at the CEO of Coinbase for supporting BCH. It's like you are not allowed to have your own opinion without getting attacked.
62 bitcoin user says Bitcoin should not be used as a cryptocurrency
63 The five stages of grief, transaction fees
64 A brief history of the attempted takeover of Bitcoin by BlockstreamCore/The legacy banking systems/The Powers That Be
65 Warning! Theymos admitted he 'misled millions of people' yet he wanna 'leave the text as it is' to mislead more people!
66 "Wait. What? My private keys need to be on an internet-connected computer in order to use Lightning Network?"
67 a year ago Adam Back accused u/Jacktenz of exaggerated claims about fees. The truth is the claims were understated!
68 Roger Ver was not selling explosives, he was selling firecrackers.
69 Core devs pop champaigne, and openly celebrate high fees. Now core supporters blame coinbase for high fees?
70 Now that we've had a few 8MB blocks, let's dispel this centralisation myth once and for all.
71 Reddit admin sodypop on censorship in /Bitcoin: "We generally allow moderators to run their communities how they like as long as they are within our site-wide rules and moderator guidelines." Blatant censorship, hacking, vote manipulation, and brigading are "within [Reddit's] site-wide rules".
72 Another obvious sockpuppet account being used to push Blockstream's agenda.
73 Totally organic grassroots support for the #NO2X "movement." Definitely not a purchased sockpuppet account, you guys.
74 Charlie Lee [Litecoin creator]: "I have sold and donated all my LTC [...] Litecoin has been very good for me financially, so I am well off enough that I no longer need to tie my financial success to Litecoin’s success"
75 If it’s inaccessible to the poor it’s neither radical nor revolutionary.
76 BSCoretabs shills are vandalizing Wikipedia to smear Roger Ver with false quoting, missparaphrasing and accusations.
77 Introducing dipshit extraordinaire Warren Togami, the link between Theymos and BlockStream
78 Debunking: "Blockstream is 3 or 4 developers out of hundreds of developers at Core" - Tone Vays
79 This blockchain debate is purely political and is not about scaling but about control. X-Post from /bitcoin
80 A profile to look at for more evidence
81 What exactly is Blockstream Core's excuse for causing a year of stagnation in Bitcoin with no end in sight?
82 We have a way to build bank-like services.
83 "There is a reason why things are done in a certain way in the financial system, and Bitcoin will be doing something similar"
84 Some thoughts about the possible Bitcoin Segwit, Bilderberg/AXA/BockStream/Core, In-Q-Tel, CIA connection.
85 Theymos on Bitcoin XT
86 (If this is not allowed mods, please remove this text) I cannot verify this yet, but a source has given me information about theymos. theymos is known as Michael Marquardt, from Wisconsin and is a graduate from the University of Wisconsin as a computer-science student.
