I'm planning to rework the
AU Solo CKPool - Anonymous Bitcoin Mining
 networking this afternoon. There will be a period of downtime while this happens, and when it returns it will likely be on a different IP address so it may take a while for your miners to recognise the change. As always, make sure to have a backup pool configured in your mining hardware.

Long Range Zip. Contribute to ckolivas/lrzip development by creating an account on GitHub.
 Lrzip is an ancient command line compression tool I created for linux based on the original Rzip tool designed to use maximum resources on modern hardware for high levels of compression in the least possible time, with optional secure encryption, and have been maintaining on and off for many years. I finally found the time to give it a long overdue maintenance and security bugfix update. All existing users are urged to update. Get it while it's hot.

I've removed the separate ckpool-solo repository from bitbucket to avoid confusion. It has long since been merged into the master ckpool branch with the same code so you will be redirected to that if you try to access it.

eusolostats.ckpool.org has been migrated to the more powerful server. Assuming everything is working fine you should notice no difference. There may be a small interruption to your statistics that occurred during the migration period. Cached local DNS on your browsers means you may not immediately switch to the new server.

solo.ckpool.org updates. The EU solostats server is running low on disk space, so I intend to migrate it to a virtual subdomain on the much higher powered server running the main solostats. The AU solo server's network performance is not meeting my expectations so it will be reconfigured over the next few days and there will be a short downtime. I will be providing notification where possible. As always, make sure to have a backup pool specified on your miners.

Be aware there is always trust involved when you mine at a pool, more so for solo blocks. New pools keep springing up without any reputation and make great offers. The least you can do is check what address the pool is mining to, if it claims to be mining solo blocks for you.

Sub 1sat/vB transaction discussion and reversal of decision to mine them on solo ckpool. Block 910440

 is the first block that solo ckpool has mined that has included sub 1sat/vB transactions. I made this change because the bulk of the mining pools are now mining transactions below the default (until now) mempool policy of mining transactions only 1sat/vB or above. The reason for switching solo ckpool was partially out of necessity - if the mempool differs substantially from what other pools are mining, when other pools mine a block with low fee transactions, solo ckpool will be slow to build new blocks. The reason is because of the disparity in what is in the pool's mempool and it missing transactions included, so it would have to ask for the missing transactions before it can build a full block. Now that solo ckpool has mined a block with sub 1sat/vB transactions I have data on the reward mined as the result of a low transaction fee period. Of the ~4900 transactions mined in this block, ~3300 were sub 1sat/vB transactions. It took some time to sift through the data of these transactions to determine what the mined fees were. They amounted to ~.0018 BTC more in fees, or ~$220. This is ~.06% of the current 3.125 BTC block reward. These particular low fee transactions were very small and appeared to create 1-2 UTXOs each. In light of how ridiculously small the extra fees mined were by accepting these transactions, and the potential for creating a significant number of new UTXOs, I am reversing my decision to mine these transactions. To maintain solo ckpool's ability to be aware of these transactions in the mempool I will only be setting the minrelaytxfee to accept and forward them, but not setting a lower blockmintxfee to mine them. The block reward needs to have dropped substantially for such low fee transactions to add meaningful reward to mining pools, and I would only consider doing so if the reward was at least 1% more. The block reward would need to have dropped below 0.2 BTC total meaning we are decades away from such fees to be significant. By that time the landscape is likely to be very different to the current one, and it is unknown if fees will remain low that far away. A lower minimum fee is also likely to worsen fees' ability to be a significant contributor to mining rewards as block subsidy diminishes. I implore other pool owners to do their own calculations and reconsider their decision to mine them at this stage.

Create your own local solo bitcoin mining ckpool & bitcoind easy install It's clear that the default ckpool installation requires a bit of linux knowhow so I've created an all-in-one script to automate the process for you. Quick instructions for most linux distributions: wget https://bitbucket.org/ckolivas/ckpool/raw/master/scripts/install-ckpool-solo.sh chmod +x install-ckpool-solo.sh sudo ./install-ckpool-solo.sh Whilst a dedicated high performance pool for regular or solo mining is still likely the preferred option for most people, everyone should have the ability to run their own truly solo mining operation even if just as their final backup. It should also be easy for as many people as possible to deploy one quickly in the case of an existential mining threat. This will download ckpool source code, v29.0 bitcoin daemon binary, check its validity, install the daemon, build ckpool, and install it, configured for solo mining, and begin downloading the blockchain. Follow the prompts or simply press enter for the default settings. Should work on any .deb or .rpm based linux distribution (ubuntu, debian, fedora, centos, rhel) to download required packages. Installs both as systemd services as the current user but can configure a new ckpool user for both. It will allow you to choose to run a pruned bitcoin blockchain to minimise hard drive storage, but it is recommended to use a full blockchain and have enough storage space to spare. The current blockchain is almost 700GB, so ideally you should at least have double this space on the drive. You will be given the option to use a checkpoint hash to speed up the initial blockchain download, or disable it for maximum paranoia. It will use any existing blockchain data in ~/.bitcoin if it exists for the chosen user. Bitcoind will be preconfigured with suitable mining defaults, and ckpool will be configured to start in solo mining mode on port 3333 on the current machine. You will be unable to mine to it until the bitcoin daemon has synced up the full blockchain. You will be given the option to enable donation to the ckpool author, and a custom signature to be added to any solved blocks. Higher performance modern computing hardware and storage is recommended if you are to maintain a dedicated local solo mine and not just a backup of last resort.

Congratulations to the 2nd solo block solver 35mU~8hK7 in 2 days for solving the 304th solo block at https://solo.ckpool.org! This was a huge miner with 270PH at the time of solving the block.

 A miner of this size has about a 1 in 20 chance of solving a block each day, however this miner doesn't appear to have been mining continuously at that hashrate for very long, and the worker size suggests this was a rental.image

Any solo bitcoin miners out there interested in me opening an AU based solo ckpool for miners in the Oceania/Asia-Pacific region?
