This event seems likely to occur in the next week. Version 2 block specification: https://en.bitcoin.it/wiki/BIP_0034 Watching for the event: http://blockorigin.pfoe.be/top.php The text is at the bottom: "We are currently at 100 out of the latest 1000 blocks on version 1 (10.00%) and 899 out of the latest 1000 blocks on version 2 (89.90%)" Users should not be impacted. Some ancient miners will produce newly-invalid blocks (v1), that will get ignored. The easy solution is to mine using a recent bitcoind (0.7 or later). If you are a miner and need help upgrading to v2, ping us on #bitcoin-dev or bitcoin-development@lists.sourceforge.net. -- Jeff Garzik exMULTI, Inc. jgarzik@exmulti.com
