This release requires a protocol upgrade.
This release contains a consensus protocol upgrade, which implements the following spec:

What's New

  • State Proofs: lightweight, cryptographically provable, portable proofs of Algorand state that let dapps on other blockchains trustlessly verify Algorand transactions, making it safer and easier to develop and use cross-chain products and services.
  • Max TPS of 6k
    • Larger blocks: ~5x increase in max-block size (from 1MB to 5MiB), allowing up to ~25k transactions per block.
    • Shorter round times: ~0.5s reduction in average round times (approaching ~3.9s).
  • AVM v7
    • On-chain randomness beacons and oracles can now be built by taking advantage the new block and vrf_verify opcodes.
    • Unfunded accounts (with 0 microalgo) can now issue transactions as long as their fees are covered by fee pooling in the transaction group.
    • App calls are now implicitly given access to the app accounts for the apps specified in the foreign apps array.
