Environment Version#

Smart Rollups#

  • The protocol can now designate a canonical rollup per chain, which can send signals to activate rollup-specific features without requiring a protocol amendment. The first supported signal, WASM_PVM_ENABLE_NEW_DURABLE_STORAGE, enables the WASM PVM to use a new backend for its durable storage. (MR !21634)

Protocol parameters#

  • Added smart_rollup_canonical_rollup_address, identifying the canonical rollup for the current chain. (MR !21634)

  • Removed allow_tz4_delegate_enable and aggregate_attestation from the parametric constants. Both feature flags had been true since their introduction (in protocols 022 and 023 respectively) and the conditional logic they gated was dead code. (MR !21007)
