SegWit Activation Progress


The Segregated Witness soft fork is well under way, we are currently signalling just over the threshold of 75% for CSV and over 50% for SegWit itself. A final mining push would help to get us over the 75% threshold. Remember to mine on a SegWit compatible pool. You can see the progress of the soft fork and which pools are upgraded on our SegWit tracker here: https://vtconline.org/sf.html. I have received confirmation this week from both Bittrex and Poloniex that they have updated their wallets to support SegWit, and the majority of pools have already upgraded.

In the last week we released v0.11.0.2 of the Vertcoin wallet which provides a number of bug fixes, improving user experience. Wallet downloads can be found here: https://github.com/vertcoin/vertcoin/releases. Furthermore, we released a new version of P2Pool that supports SegWit, as well as a Windows build which does not require any dependencies besides a Vertcoin wallet. The release can be found here: https://github.com/vertcoin/p2pool-vtc/releases. P2Pool is the recommended mining method for VTC as it helps to decentralise the network, maximise miner uptime and minimise mining fees. A list of public P2Pool nodes can be found here: https://scanner.vtconline.org/ although it is very easy to run your own node.

Thanks, and let’s bring on SegWit.

Vertcoin SegWit Wallet Release

I am pleased to announce the release of the Vertcoin SegWit soft fork. This wallet updates Vertcoin to use the latest Bitcoin Core v0.13 base. Thus, it soft forks BIP34, 66, 65, CSV and SegWit into Vertcoin as well as the other BIPs included in Bitcoin Core since v0.8. The soft forks will start signalling compliance from block 675,360 and will continue to signal for a year. Once 75% of blocks over a 2016 block period have signalled, after another 2016 block period the soft forks will activate and old version blocks will be orphaned from that point on. Therefore it is highly recommended you upgrade your wallet and this update should be treated as mandatory. It is especially important that pools upgrade as we need at least 75% of blocks mined to be upgraded in order to activate the soft forks. Pools that do not upgrade could risk orphaned blocks after activation. Everyone else, including users and exchanges, should upgrade too to guard against forking after activation.

Remember to backup your wallet.dat before you upgrade your wallet. Failing to do so could result in the loss of all your coins.

Miners themselves will not have to do anything, but pool operators will need to upgrade their pool software to be compatible with the new wallet. We have a version of stratum-mining that is confirmed working. An upgraded p2pool version is in development and should be released soon.

Wallet update – v0.10.1.0

Hello everyone,

I am pleased to announce the release of Vertcoin v0.10.1.0. This is intended to be the final “old client” release before the SegWit update, hopefully coming before the end of the month. This wallet update prepares the way for SegWit by deprecating Stealth Addresses since they will not be available in the next wallet version. Those still using stealth should continue to use their current wallet until they are satisfied they have redeemed all of their stealth inputs as there is no way to retrieve them from this wallet release. Additionally, this release implements lowS signatures which are required for BIP66. Finally, it updates the default transaction fee structure so that transactions from this wallet will be propagated by the new wallet once it is released.

Whilst this update is not mandatory, it is highly recommended as it will take longer and longer for pre-v0.10.1 wallets’ transactions to be included in a block as more of the network upgrades to the new SegWit wallet.

The release can be found here: https://github.com/vertcoin/vertcoin/releases



Vertcoin has hard forked – downgrade your wallets!

Hello everyone,

Unfortunately I learned that Vertcoin had hard forked during the night between old (v0.10.0.*) and new (13.99.0) wallets. This has lead to old wallets on one chain and new ones on the other. Given that only around 7% of the network has switched so far to the new wallet, I ask that everyone who has upgraded, downgrade their wallet to v0.10.0.2 and those who have not yet upgraded to stay put.

On that basis, the development team will be evaluating the fork to determine its cause and if possible release a patch and retry the soft fork. Failing that, we intend to hard fork the coin, sometime in the next month.

You can find the old wallet for download here: https://github.com/vertcoin/vertcoin_old/releases

Thank you for your patience,


Vertcoin Wallet Update – SegWit Soft Fork

The Vertcoin team is pleased to announce the release of a new wallet update. This update implements the SegWit soft fork which will begin signalling on the 13th February 2017 and will require 75% of a thousand blocks updated in order to activate. Everyone should upgrade to the new wallet, especially mining pools. The procedure is much the same as the two hard forks we have performed previously, pools will need to update their pool software to a new version compatible with the new wallet if the community wants SegWit to activate. Old wallets (v0.10.0.*) will continue to work after the fork, but it is important that everyone upgrades. Please remember to backup your wallet.dat file before upgrading. Those using P2Pool for mining (the recommended method) will need to update their pool software too, I will post an update in a couple of days with a new P2Pool release. A new stratum-mining (for MPOS based pools and solo miners) has been provided below along with a list of already upgraded pools.

Development update

Hello everyone,

The Vertcoin Development team has been busy the last month working on updating our wallet to the latest Bitcoin core with Segregated Witness (segwit). If you’re not familiar with segwit you can read the benefits and purpose here ( https://bitcoincore.org/en/2016/01/26/segwit-benefits/). With that being said we are excited to announce that everything is working as it should on the test-net ,and if time permits we should have the new release ready sometime early next week, if not sooner. This should serve as a heads up to miners and pools since we will need a 75% consensus for segwit to activate. Please spread the word.

Vertcoin Foundation & Roadmap

Hello everyone,

A number of community members have gathered on the new Vertcoin Slack channel, which you can join from IRC (#vertcoin on Freenode), and we have decided to use the development fund to revitalise Vertcoin’s development and economy. The development fund still contains ~$850 (see it on the blockchain), and with further contributions from both myself and various other members of the community, we intend to start a foundation to support Vertcoin’s growth. This foundation will be not-for-profit, supported by donations and investments, and have enshrined in its bylaws Vertcoin’s commitment to ASIC resistance and accessibility of mining to all. Its focusses will be to fund the technical development of the Vertcoin wallet and its associated support software and to grow Vertcoins economy through marketing, information provision, business support, various public services like block explorers, full nodes, merchant lists and also economic stimulus where possible. The exact details surrounding the formation of the foundation are not yet concrete as I need to further research the tax situation surrounding cryptocurrency and low-income non-profits among the various options, but I will report back once I know more.

Next, as you can probably tell since you are reading this on the Vertcoin website, I now have access to the website server again. I am also now an admin on the VTC Facebook page and I hope to acquire the login details for the Vertcoin Twitter account too. This will allow us to improve our online presence and make Vert more accessible. To that end, the website needs a total content overhaul since most of is outdated. The Bitcoin website is a great example in terms of the content and ease of access that we should be providing to users and I intend to deliver that. Soon, I will make another blog post enumerating the bounties I will make available for writing content for the website. The website update will coincide with an increase in our social media activities to promote the use of Vertcoin.

My recent experiences using Bitcoin as a micropayments processor have been pretty awful. Often I find myself waiting several hours for a single confirmation, even when I have included the recommended fee which now averages at $0.23 per transaction, which is a lot considering that Vertcoin’s transaction fees are essentially 0. Therefore, in the short to medium term, I think we should be positioning Vertcoin as a far cheaper and faster alternative to Bitcoin with the added advantage of a decentralised mining network, four times the capacity and privacy using Stealth Addresses.

In order to be that alternative, however, Vertcoin’s wallet needs refreshing, mining needs to be more accessible and merchants need to be more prominent. The wallet initially needs a maintenance update to fix test net, update the nodes list, copyright years, explorer URL, documentation and checkpoints. After this has been completed there is some low-hanging fruit for us to pick. Stealth addresses appear to be working but are buggy, temperamental and hard to use. Firstly, in order to detect the receipt of a stealth transaction, one has to rescan the entire blockchain which locks out the interface until this process is completed. Then, the transactions, if found, are not added to the transactions list but rather just added to the inputs list which is not obvious to the user. Finally, the scanning process is supposed to start off from its last scanned location, but this feature is broken. Below is my intended version roadmap for dealing with these issues. Tasks that have been completed have been struck off.

Wallet Roadmap

v0.10.0.2 (estimated in the next couple of weeks)

  1. Update the nodes list in the wallet
  2. Update the copyright years
  3. Update the READMEs, including build instructions for Windows, OS X and Ubuntu/Debian
  4. Add some new checkpoints
  5. Fix test net
  6. Update the explorer URL
  7. Build wallets (GUI and command line) (Do we still need to provide 32-bit binaries?)
    1. Windows
    2. OS X
    3. Ubuntu/Debian

v0.10.0.3 (estimated during Q1 2017)

  1. Make sure stealth transactions show up in the transactions panel
  2. Update stealth addresses to use the latest version of the secp256k1 library
  3. Fix stealth rescanning from the start of the blockchain every time
  4. Move stealth address search to a separate thread so it does not lock out the GUI and provide a progress bar and cancel button
  5. Ensure stealth is working properly in the daemon via the command line
  6. Update nodes, checkpoints, etc
  7. Build wallets

In terms of mining, we will be releasing an update for P2Pool soon and I intend to support the creation of a one-click miner soon. In an effort to update some of the information available regarding Vertcoin related services, I have compiled this list of active services/merchants/websites: http://vtconline.org/.

I have a number of ideas for long-term plans for VTC, the main one of which will require a complete rewrite, but I think is possible once we have more interest and funding. I will make a further blog post when my ideas are more fleshed out.

If you have any time that you are able to contribute to the project, please do not hesitate to contact me at [email protected], post or PM me on Reddit or join our IRC channel #vertcoin. We are particularly looking for people with programming experience, preferably C++. You can donate to the development fund using the address: VpBsRnN749jYHE9hT8dZreznHfmFMdE1yG. Any donation you can make would be greatly appreciated.

Kind regards,

Hard Fork at block 347000


I am pleased to announce that the new version of Lyra2RE is ready. We will be hard forking to the new mining algorithm at block number 347000 (estimated to be around the 10th of August). In order for this to go ahead smoothly, everyone must update their wallet software to the latest version and miners must use the new miner software after the fork block. This update is MANDATORY; failure to upgrade could see your coins getting lost on the wrong fork. As referenced in my previous post, this update is intended to thwart the botnet mining on the network. The new algorithm provides a far greater ratio of GPU to CPU hashrate meaning that once again GPUs will become the dominant Vertcoin mining force.

Binaries for most platforms can be found here: https://github.com/vertcoin/vertcoin/releases/tag/v0.10.0.0. A 32-bit Windows variant is missing but if it has popular demand then I will get one released, otherwise I do not think one is really needed. The mining software for AMD, nVidia and CPUs are done and will follow shortly.

Kind Regards,
