- Initialized from a mainnet snapshot. - No difficulty checks and no retargets for quick blocks. - Allow for several blocks at the same VDF step. - Flexible chunk picking. - Dedicated mining server that builds blocks from sampled chunks. - Seeded with 20 MiB of early weave data. - ./bin/localnet_shell
For a start, protocol.mdc only describes a caveat that recall bytes are independent from sub-chunks, which Claude Opus 4.5 struggled to understand.

We also drop the fallback to reading from in-memory block cache which we do not really need so can simplify the code.
ar_packing_tests, ar_vdf_block_validation_tests, ar_vdf_server_tests are failing hitting 429 since the rate limit restructuring update.
Introduce the possibility to start and stop block gossip, add ar_test_node:with_gossip_paused/2
Increase mining_cache_size_mb and reduce hashing_threads

Timeout error from wait_until_joined is ignored
Medium Severity
The wait_until_joined() function returns {error, timeout} if the node fails to join within the 200-second timeout, but this return value is discarded. The code immediately proceeds to call submit_snapshot_data() regardless, which will fail or produce undefined behavior since the node hasn't finished joining. The return value of wait_until_joined() should be checked, and startup should fail gracefully if the timeout is reached.

Adds a new

LOCALNET, mining/validation logic is relaxed or overridden to enable deterministic local mining: swaps inar_localnet_mining_servervia supervisor selection, allows bypassed difficulty/retarget checks, special-cases nonce limiter step comparisons/validation, and allows precomputed recall ranges/step counts for PoA validation.Written by Cursor Bugbot for commit 7a24c4b.
