Quote If 950 of the last 1,000 blocks are version 2 or greater, reject all version 1 blocks

We are getting close to that threshold: 821 out of the latest 1000 blocks were version 2.



If you are mining in a pool: there is a list of pools and what versions they are producing



If you are mining with p2pool or solo and using a very old version of bitcoind: you should upgrade, or you risk your blocks getting orphaned.

Last July, BIP 34 was accepted. It specifies a "soft fork":We are getting close to that threshold: 821 out of the latest 1000 blocks were version 2.If you are mining in a pool: there is a list of pools and what versions they are producing here. If your pool is producting version=1 blocks, you should urge your pool operator to upgrade or patch.If you are mining with p2pool or solo and using a very old version of bitcoind: you should upgrade, or you risk your blocks getting orphaned. How often do you get the chance to work on a potentially world-changing project?

I know Graet (ozcoin) doesn't quite want to take down the getwork/merged mining server yet (and strand those users by our hand), but take Deepbit out of the equation completely, and if the top 4 pools were to all make a clean break it would happen. However I was hoping for a rolling plan like slush proposed back in February, and I rather users update their software compared to just getting shut out. I know it will happen in time so patience is a virtue here Bitcoin - 3DTcMYT8SmRw4o4Lbq9cvm71YaUtVuNn29

Do note that this isn't a hard-fork. It just means if you continue trying to mine v1 blocks, they will not be accepted by the rest of the network. It's highly unlikely this would ever go beyond a single orphaned block, given the amount of hash power that is mining v2 blocks, and the amount of nodes that will refuse to forward your block.



This has been a "rolling plan". It's been in place for 8 months, and only takes place when a supermajority of 95% is on v2. Do note that this isn't a hard-fork.

If you're a miner using a merge mining patch you might want to check that your coinbase is correct otherwise when the supermajority happens your blocks will be orphaned if the coinbase is wrong.

In the text on the bottom you will see the counts in blocks on v1. 95% is required so if the number of blocks on v1 drop below 50 over the last 1000 blocks, all blocks v1 will be rejected! FYI: The blockorigin site keeps track of the last 1000 blocks on http://blockorigin.pfoe.be/top.php In the text on the bottom you will see the counts in blocks on v1. 95% is required so if the number of blocks on v1 drop below 50 over the last 1000 blocks, all blocks v1 will be rejected!
