• None included in this release

Aptos Blockchain

General

• Upgraded rust to version 1.78.0.

Consensus

• Small optimizations to consensus broadcast to: (i) prioritize distant peers first; (ii) parallelize message serialization more effectively.

Networking

• Small performance improvements for message deserialization at the networking layer.

Move

VM

• Updated type size calculation to account for all nodes in non-substituted types. Also introduced TypeBuilder struct to construct types with maximum depth and count.
• Added a procedural macro bytecode_spec so that inline specifications to the Move bytecode instructions can be defined in Rust.
• Added runtime environment outside of VM. The env can be used cached and possibly shared across VM instances.

Gas

• Fixed gas charging in crypto_algebra::serialize() API implementation.

Resolved Issues

• Upgrade Rust to v1.78.0

What's Changed

• cherry-pick 56ca46302b934b0bb0384c1034b6c62685d82b3f by @areshand in https://github.com/aptos-labs/aptos-core/pull/13836
• [Bug] Network Health Checker. Fixes a infinite blocking call in Network Health Checker when attempting to disconnect from a peer that failed the Health check. The situation arises when a peer connection is blocked writing to a socket unable to process disconnection request from the Health Checker, while the Health Checker is waiting for peer connection termination acknowledgement. The fix also includes a timeout for writing to an outbound socket.

Aptos Improvement Proposals (AIPs)

Check out all of our AIPs and discussions here on GitHub

Breaking Changes

• [AIP-88] - BlockEpilogue to replace StateCheckpoint transaction
  • Ecosystem Impact: StateCheckpoint transaction will stop being produced, and BlockEpilogue will be produced instead. For users that handle receiving unknown transactions, no issues should occur. For users that need to handle all transaction, they would need to add handling for the new transaction type.
  • Feature Flag: gated with execution onchain config

Aptos Blockchain

• https://github.com/aptos-labs/aptos-core/pull/13133 BlockSTM: Parallelize Resource Group Accesses. Different resources in a resource group won't have a conflict for parallelism purposes in most cases. Improves the throughput of resource group based workload by up to 2x.
• https://github.com/aptos-labs/aptos-core/pull/13531 Mempool: Reduces the number of duplicate transactions due to PFN duplication. In most cases, the upstream VFN will have already seen the txn via the primary VFN's quorum store batch.

Move

VM

• Correct type size computation: https://github.com/aptos-labs/aptos-core/pull/13028/. Note that the feature flag will be enabled in 1.16, and this release rolls out the APIs first with the same type size computations.

Resolved Issues

Bug Fixes

• Multisig V2 bug fixAborts the multisig transaction if the provided payload does not match the payload stored onchain. This resolves [this filed issue](https://github.com/aptos-labs/aptos-core/issues/12929).
  • Feature flag: ABORT_IF_MULTISIG_PAYLOAD_MISMATCH
• Network Health Checker. Fixes a infinite blocking call in Network Health Checker when attempting to disconnect from a peer that failed the Health check. The situation arises when a peer connection is blocked writing to a socket unable to process disconnection request from the Health Checker, while the Health Checker is waiting for peer connection termination acknowledgement. The fix also includes a timeout for writing to an outbound socket.

Who needs to upgrade:

• Validator: Yes, by Jun 20th
• Fullnodes: Yes, by Jun 26th

What's Changed

• Cherry-pick commit to stop warn logs from DB API by @areshand in https://github.com/aptos-labs/aptos-core/pull/13722

Aptos Improvement Proposals (AIPs)

Check out all of our AIPs and discussions here on GitHub.

Breaking Changes

• [AIP-70] Parallelize Fungible Assets - opt-in parallel fungible balance
  • Ecosystem Impact: In order to track fungible asset balances correctly (for the accounts that opt-in to the new feature), now both old and new field needs to be summed up: FungibleStore.balance + ConcurrentFungibleBalance.balance. If using indexer, this change will make it transparently handled by provided processors. fungible_asset::balance view function will continue providing correct balance.
  • Dependencies: None
  • Feature Flag: CONCURRENT_FUNGIBLE_BALANCE

New features and enhancements

• [AIP-85] Improve APT FA performance

  • Ecosystem Impact: None
  • Dependencies: None
  • Feature Flag: OBJECT_NATIVE_DERIVED_ADDRESS

• [AIP-86] BN254 elliptic curve arithmetic in Move

  • Ecosystem Impact: New move Modules in Aptos framework
  • Dependencies: ark-bn254
  • Feature Flag: BN254_STRUCTURES

• [AIP-87] Introduce native API to evaluate aggregator value is greater or equal to given amount

  • Ecosystem Impact: None
  • Dependencies: None
  • Feature Flag: AGGREGATOR_V2_IS_AT_LEAST_API

• [AIP-89] Consensus latency reduction using order votes

  • Ecosystem Impact: Reduces the consensus latency by 100ms. There is no change in the execution, transaction output structure or indexer.
  • Dependencies: None
  • On chain consensus config flag: order_vote_enabled

• [AIP-90] Add Apple as a supported OIDC provider

  • Ecosystem Impact: Keyless accounts can now be backed by Apple accounts.
  • Dependencies: None
  • Feature Flag: None; but requires a governance proposal to activate

Aptos Blockchain

State sync

• Fixed warning log from latency monitor complaining about “unable to read the latest block timestamp”

Consensus

• Implemented a new “order votes” mechanism to reduce the consensus latency. Earlier, it takes for 4 hops of latency for a block to be ordered after the block is proposed. The new order votes mechanism reduces the latency to 3 hops. To achieve this, when a validator obtains the QC on a block r, the validator immediately signs the QC and broadcasts a new type of vote called “order vote”. This results in obtaining a 2-chain QC on the block r one hop earlier. The feature is added behind the new order_vote_enabled flag in onchain consensus config. The flag is currently disabled and will be enabled later on with an AIP approval.

Aptos Improvement Proposals (AIPs)

Check out all of our AIPs and discussions here on GitHub

New features and enhancements

• [AIP-73] Dispatchable Token Standard]: Developers can define their custom way of withdrawing and deposit for their fungible asset, allowing for a much more extensible way of using our Aptos Framework.
  • Ecosystem Impact: Defi developers. The token issuer can now create customized hook logic upon transfer. Calling of those hooks would be handled automatically by Aptos Framework so no api change is actually needed from the smart contract side. However, meaning of transfer could now be a bit more nuanced due to the hook logic and token issuer will have more freedom on what to do upon transfer.
  • Feature Flag: DISPATCHABLE_FUNGIBLE_ASSET
• [AIP-83] Framework-level Untransferable Fungible Asset Stores: Prevents transfers of an object even with a TransferRef. This can only be enabled during the construction of an object.
  • Ecosystem Impact: Smart contact developers

Aptos Blockchain

Quorum Store

• Improved logic for filtering duplicate transactions.

Storage

• fixed performance issue where on node bootup truncation was done repeatedly on the state value data set
• Performance improvement by adding StateKeyRegistry and avoid duplicating StateKeys at runtime.
• Performance improvement by replacing small HashSets on JMT internal Nodes with ordered Slices (Node cloning is faster).
• Performance improvement when throughput is high, by execution layer not requesting SMT internal nodes from the DB that are already cached.

Move

VM

• Refactor MoveResolver to be used inside the VM only.
• Support new randomness annotation parameter for customized gas deposit. (AIP: TBD).
• Fixed error reporting logic in VM when a new frame is created

Framework

New features and enhancement

• [AIP-61] Keyless accounts: Allows users to effectively create “keyless” blockchain accounts that are secured via the user’s existing Web 2 account (e.g., their Google account) and not via a secret key, which can be lost very easily.
  • Ecosystem Impact: SDK for Dapp and wallet developers to enable keyless accounts secured via, say, “Sign in with Google” flows
  • Related: [AIP-75] Prover Service. Does zero-knowledge proof computation on behalf of Aptos Keyless users during login, enabling fast and private authentication for Keyless accounts.
• [AIP-63] Coin to Fungible Asset Migration: This AIP proposes a global mapping to treat coins and fungible assets interchangeably, facilitating migration by converting CoinStore<CoinType> to PrimaryFungibleStore.
  • Ecosystem Impact: After enabled, Dapps and exchanges should kickoff the migration to update the balance view.
  • Feature Flag: COIN_TO_FUNGIBLE_ASSET_MIGRATION
• [AIP-71] Refactor Aptos Framework Events with Module Events: This AIP proposes a migration plan for all handle events (event v1) in Aptos Framework to module events (event v2) with double emitting.
  • Ecosystem Impact: After enabled, Dapps would see both v1 and v2 events. They should start to migrate their event tracking from event v1 to v2.
  • Feature Flag: MODULE_EVENT_MIGRATION
• [AIP-79] Implementation of instant on-chain randomness
  • Dependencies: AIP-64
  • On-chain configs: randomness_config, randomness_api_v0_config
