CHECKLOCKTIMEVERIFY is a -new opcode that allows a script to check if a specific block height or time has -been reached, failing the script otherwise. This enables a wide variety of new -functionality such as time-locked escrows, secure payment channels, etc. - -BIP65 implements CHECKLOCKTIMEVERIFY by introducing block version 4, which adds -additional restrictions to the NOP2 opcode. The same miner-voting mechanism as -in BIP34 and BIP66 is used: when 751 out of a sequence of 1001 blocks have -version number 4 or higher, the new consensus rule becomes active for those -blocks. When 951 out of a sequence of 1001 blocks have version number 4 or -higher, it becomes mandatory for all blocks and blocks with versions less than -4 are rejected. - -Bitcoin Core's block templates are now for version 4 blocks only, and any -mining software relying on its `getblocktemplate` must be updated in parallel -to use either libblkmaker version 0.4.3 or any version from 0.5.2 onward. If -you are solo mining, this will affect you the moment you upgrade Bitcoin Core, -which must be done prior to BIP65 achieving its 951/1001 status. If you are -mining with the stratum mining protocol: this does not affect you. If you are -mining with the getblocktemplate protocol to a pool: this will affect you at -the pool operator's discretion, which must be no later than BIP65 achieving its -951/1001 status. - Automatically use Tor hidden services -------------------------------------
