Version 0.21.0

This release focuses on preparing fuel-core for the mainnet environment:

  • Most of the changes improved the security and stability of the node.
  • The gas model was reworked to cover all aspects of execution.
  • The benchmarking system was significantly enhanced, covering worst scenarios.
  • A new set of benchmarks was added to track the accuracy of gas prices.
  • Optimized heavy operations and removed/replaced exploitable functionality.

Besides that, there are more concrete changes:

  • Unified naming conventions for all CLI arguments. Added dependencies between related fields to avoid misconfiguration in case of missing arguments. Added --debug flag that enables additional functionality like a debugger.
  • Improved telemetry to cover the internal work of services and added support for the Pyroscope, allowing it to generate real-time flamegraphs to track performance.
  • Improved stability of the P2P layer and adjusted the updating of reputation. The speed of block synchronization was significantly increased.
  • The node is more stable and resilient. Improved DoS resistance and resource management. Fixed critical bugs during state transition.
  • Reworked the Mint transaction to accumulate the fee from block production inside the contract defined by the block producer.

FuelVM received a lot of safety and stability improvements:

  • The audit helped identify some bugs and errors that have been successfully fixed.
  • Updated the gas price model to charge for resources used during the transaction lifecycle.
  • Added no_std and 32 bit system support. This opens doors for fraud proving in the future.
  • Removed the ChainId from the PredicateId calculation, allowing the use of predicates cross-chain.
  • Improvements in the performance of some storage-related opcodes.
  • Support the ECAL instruction that allows adding custom functionality to the VM. It can be used to create unique rollups or advanced indexers in the future.
  • Support of transaction policies provides additional safety for the user.
    It also allows the implementation of a multi-dimensional price model in the future, making the transaction execution cheaper and allowing more transactions that don't affect storage.
  • Refactored errors, returning more detailed errors to the user, simplifying debugging.

  • #1469: Replaced usage of MemoryTransactionView by Checkpoint database in the benchmarks.
  • #1468: Bumped version of the fuel-vm to v0.40.0. It brings some breaking changes into consensus parameters API because of changes in the underlying types.
  • #1466: Handling overflows during arithmetic operations.
  • #1460: Change tracking branch from main to master for releasy tests.
  • #1454: Update gas benchmarks for opcodes that append receipts.
  • #1440: Don't report reserved nodes that send invalid transactions.
  • #1439: Reduced memory BMT consumption during creation of the header.
  • #1434: Continue gossiping transactions to reserved peers regardless of gossiping reputation score.
  • #1408: Update gas benchmarks for storage opcodes to use a pre-populated database to get more accurate worst-case costs.
  • #1399: The Relayer now queries Ethereum for its latest finalized block instead of using a configurable "finalization period" to presume finality.
  • #1397: Improved keygen. Created a crate to be included from forc plugins and upgraded internal library to drop requirement of protoc to build
  • #1395: Add DependentCost benchmarks for k256, s256 and mcpi instructions.
  • #1393: Increase heartbeat timeout from 2 to 60 seconds, as suggested in this issue.
  • #1392: Fixed an overflow in message_proof.
  • #1390: Up the ethers version to 2 to fix an issue with tungstenite.
  • #1383: Disallow usage of log crate internally in favor of tracing crate.
  • #1380: Add preliminary, hard-coded config values for heartbeat peer reputation, removing todo.
  • #1377: Remove DiscoveryEvent and use KademliaEvent directly in DiscoveryBehavior.
  • #1366: Improve caching during docker builds in CI by replacing gha
  • #1358: Upgraded the Rust version used in CI to 1.72.0. Also includes associated Clippy changes.

  • #1342: Add error handling for P2P requests to return None to requester and log error.
  • #1318: Modified block synchronization to use asynchronous task execution when retrieving block headers.
  • #1314: Removed types::ConsensusParameters in favour of fuel_tx:ConsensusParameters.
  • #1302: Removed the usage of flake and building of the bridge contract ABI.
    It simplifies the maintenance and updating of the events, requiring only putting the event definition into the codebase of the relayer.
  • #1293: Parallelized the estimate_predicates endpoint to utilize all available threads.
  • #1270: Modify the way block headers are retrieved from peers to be done in batches.

Breaking

  • #1506: Added validation of the coin's fields during block production and validation. Before, it was possible to submit a transaction that didn't match the coin's values in the database, allowing printing/using unavailable assets.
  • #1491: Removed unused request and response variants from the Gossipsub implementation, as well as related definitions and tests. Specifically, this removes gossiping of ConsensusVote and NewBlock events.
  • #1472: Upgraded fuel-vm to v0.42.0. It introduces transaction policies that changes layout of the transaction. FOr more information check the v0.42.0 release.
  • #1470: Divide DependentCost into "light" and "heavy" operations.
  • #1464: Avoid possible truncation of higher bits. It may invalidate the code that truncated higher bits causing different behavior on 32-bit vs. 64-bit systems. The change affects some endpoints that now require lesser integers.
  • #1432: All subscriptions and requests have a TTL now. So each subscription lifecycle is limited in time. If the subscription is closed because of TTL, it means that you subscribed after your transaction had been dropped by the network.
  • #1407: The recipient is a ContractId instead of Address. The block producer should deploy its contract to receive the transaction fee. The collected fee is zero until the recipient contract is set.
  • #1407: The Mint transaction is reworked with new fields to support the account-base model. It affects serialization and deserialization of the transaction and also affects GraphQL schema.
  • #1407: The Mint transaction is the last transaction in the block instead of the first.
  • #1374: Renamed base_chain_height to da_height and return current relayer height instead of latest Fuel block height.
  • #1367: Update to the latest version of fuel-vm.
  • #1363: Change message_proof api to take nonce instead of message_id
  • #1355: Removed the metrics feature flag from the fuel-core crate, and metrics are now included by default.
  • #1339: Added a new required field called base_asset_id to the FeeParameters definition in ConsensusParameters, as well as default values for base_asset_id in the beta and dev chain specifications.
  • #1322:
    The debug flag is added to the CLI. The flag should be used for local development only. Enabling debug mode:
    - Allows GraphQL Endpoints to arbitrarily advance blocks.
    - Enables debugger GraphQL Endpoints.
    - Allows setting utxo_validation to false.
  • #1318: Removed the --sync-max-header-batch-requests CLI argument, and renamed --sync-max-get-txns to --sync-block-stream-buffer-size to better represent the current behavior in the import.
  • #1290: Standardize CLI args to use - instead of _.
  • #1279: Added a new CLI flag to enable the Relayer service --enable-relayer, and disabled the Relayer service by default. When supplying the --enable-relayer flag, the --relayer argument becomes mandatory, and omitting it is an error. Similarly, providing a --relayer argument without the --enable-relayer flag is an error. Lastly, providing the --keypair or --network arguments will also produce an error if the --enable-p2p flag is not set.
  • #1262: The ConsensusParameters aggregates all configuration data related to the consensus. It contains many fields that are segregated by the usage. The API of some functions was affected to use lesser types instead the whole ConsensusParameters. It is a huge breaking change requiring repetitively monotonically updating all places that use the ConsensusParameters. But during updating, consider that maybe you can use lesser types. Usage of them may simplify signatures of methods and make them more user-friendly and transparent.

Removed

Breaking

  • #1484: Removed --network CLI argument. Now the name of the network is fetched form chain configuration.
  • #1399: Removed relayer-da-finalization parameter from the relayer CLI.
  • #1338: Updated GraphQL client to use DependentCost for k256, mcpi, s256, scwq, swwq opcodes.
  • #1322: The manual_blocks_enabled flag is removed from the CLI. The analog is a debug flag.
