MainNet and TestNet Update: 3.9.2

post by devops-service on Sep 6, 2022

Algorand Inc

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 of 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.
