If you +are solo mining, this will affect you the moment you upgrade Darkcoin Core, +which must be done prior to BIP66 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 BIP66 achieving its +951/1001 status. + + +BIP 66: strict DER encoding for signatures +------------------------------------------ + +Darkcoin Core 0.11.2 implements BIP 66, which introduces block version 3, and a +new consensus rule, which prohibits non-DER signatures. Such transactions have +been non-standard since Darkcoin 0.8, but were technically still permitted +inside blocks. + +This change breaks the dependency on OpenSSL's signature parsing, and is +required if implementations would want to remove all of OpenSSL from the +consensus code. + +The same miner-voting mechanism as in BIP 34 is used: when 751 out of a +sequence of 1001 blocks have version number 3 or higher, the new consensus +rule becomes active for those blocks. When 951 out of a sequence of 1001 +blocks have version number 3 or higher, it becomes mandatory for all blocks. + +Backward compatibility with current mining software is NOT provided, thus +miners should read the first paragraph of "Mining and relay policy +enhancements" above. + +Also compare with [upstream release notes](https://github.com/bitcoin/bitcoin/blob/0.10/doc/release-notes.md#mining-and-relay-policy-enhancements). + +More info on [BIP 66](https://github.com/bitcoin/bips/blob/master/bip-0066.mediawiki). + + +How to Upgrade +-------------- + +If you are running an older version, shut it down.
