PoW hardfork — MANDATORY update before block 280000

At block height 280000 the TSN network switches from the current proof-of-work to a memory-hard, CPU-friendly PoW. Every node carries the same baked activation height.

You must update to this build before block 280000. Nodes still on an earlier build will reject post-fork blocks and stop following the live chain after that height.

What changes at 280000

  • Mining becomes memory-hard: CPUs are the intended miners; GPUs lose their advantage.
  • No wire-format change and no re-mining of existing blocks — only the PoW function changes, at that height.

Verify you have the armed build

After starting ./tsn service-node, run:

curl -s http://localhost:9437/v2/consensus-params

It must show "pow_cachehard_activation_height":280000 and "pow_cachehard_armed":true.

The internal version string still reads 3.0.0-rc.26; the definitive check is the field above and the SHA256 below.
