We are planning to release go-algorand v3.9.0-beta on Thu Aug 11, 10:30am EDT (2:30pm UTC).

IMPORTANT
This release requires a protocol upgrade.
This release contains a consensus protocol upgrade, which implements the following spec: GitHub - algorandfoundation/specs at 2dd5435993f6f6d65691140f592ebca5ef19ffbd

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.

Additional Resources

To update to the current version of BetaNet, you can run the following goal command:

./update.sh -c beta -i -d <betanet-data-directory> -n

If you haven’t already done so, we also advise setting up a CRON job to automatically update your algorand networks. If you haven’t done this for BetaNet, you can follow the instructions here:
