**This release requires a protocol upgrade.**   
 This release contains a consensus protocol upgrade, which implements the following spec: [GitHub - algorandfoundation/specs at 433d8e9a7274b6fca703d91213e05c7e6a589e69](https://github.com/algorandfoundation/specs/tree/433d8e9a7274b6fca703d91213e05c7e6a589e69) |

# 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.
