Blazecoin Core 2.1.1 (Linux)

Blazecoin Core 2.1.1 — maintenance release: the post-quantum fork checkpoint and refreshed sync anchors.

A small release on top of 2.1.0. Consensus is unchanged: a 2.1.0 node and a 2.1.1 node follow the same rules and stay on the same chain. Upgrading is recommended but not mandatory.

What is in this release

• Checkpoint at block 4,250,000, the post-quantum activation height (H_Q, passed on 2026-09-16). A node syncing from scratch now rejects any chain that disagrees with the real history at the fork, before it has done the work of validating it.
• Fresh initial-sync anchors. defaultAssumeValid moves to block 4,319,107 (2026-10-09), with the minimum chain work set to that block's exact chain work and the chain statistics (4,849,335 transactions, one-year rate) refreshed from the same anchor. A new node skips signature checks up to that block on its first sync, as 2.1.0 did up to block 4,168,925; proof of work is still checked on every block.
• Version 2.1.1 is reported by getnetworkinfo and --version.

Upgrade: stop the old daemon (blazecoin-cli stop), replace blazecoind and blazecoin-cli, start again. No rescan or re-index is needed. Wallets, data directories and configuration carry over unchanged.
