IMPORTANT UPDATE
Sixbit Core 2.2.0 is out – a required upgrade (hard fork) at block 34,083.The Sixbit chain has been stuck at block 34,082 since 12 October. A large miner pushed the difficulty to 38.8 million and then left, and under the old rule the difficulty would not change for another 190 blocks. That's weeks or months for the miners who are left.
What 2.2.0 changes, from block 34,083:- ASERT difficulty with Shears StallGuard: the difficulty adjusts every block. If no block is found for 2 hours it eases off, so one big miner leaving can never freeze the chain again. It restarts at about 1,000,000, with a floor of about 100,000.
- AuxPoW (merge-mining): Sixbit can be merge-mined alongside Bitcoin (chain ID 6006). Ordinary solo blocks still work.
Nothing else changes: supply, block reward, halvings, 10-minute target, addresses and balances. All history up to block 34,082 stays exactly as it is.

Timing: we will start mining block 34,083 from
Thursday 12 November. If you run a Sixbit node, pool or exchange, please upgrade to 2.2.0 before then. Older nodes will stop following the chain at 34,083.
The original Sixbit team is no longer actively maintaining the code, so this release was prepared by Shears Mining with the Sixbit community and published openly. Questions and code review are very welcome.
