Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

As a minor extension, we have adopted a slightly different versioning convention for the Mithril distributions (https://mithril.network/doc/adr/3#decision)

Mithril Distribution [XXXX] - UNRELEASED

  • Support for Mithril nodes footprint support in Prometheus monitoring in infrastructure.

  • Add support for custom HTTP headers in Mithril client WASM library.

  • Support file:// URLs for snapshot locations in Mithril client.

  • Support for Mithril signer memory optimization when signing Cardano transactions with multiple Merkle tree storage backends.

  • UNSTABLE Cardano stake distribution certification:

    • Implement the signable and artifact builders for the signed entity type CardanoStakeDistribution.
    • Implement the HTTP routes related to the signed entity type CardanoStakeDistribution on the aggregator REST API.
    • Added support in the mithril-client library for retrieving CardanoStakeDistribution by epoch or by hash, and for listing all available CardanoStakeDistribution.
    • Implement CardanoStakeDistribution commands under the --unstable flag in the Mithril client CLI to list all available CardanoStakeDistribution and to download artifact by epoch or hash.
    • Implement mithril-client library functions related to CardanoStakeDistribution within the WASM library.
    • Add new tab Cardano Stake Distribution in the explorer.

  • Crates versions:

Crate Version

Mithril Distribution [2430.0] - 2024-07-30

  • mithril-aggregator node produces artifact for different signed entity types in parallel.

  • Fix Agency is theirs error in the ChainReader when the underlying Chain sync client does not have agency.

  • Support for Cardano node 9.1.0 in the signer and the aggregator.

  • Support better disk configuration in terraform deployments with the CI/CD workflows.

  • UNSTABLE Cardano transactions certification:

    • Make Cardano transaction signing settings configurable via the CD.

  • Crates versions:

Mithril Distribution [2428.0] - 2024-07-15

  • Provide a feature to the mithril-client crate to allow selection of the TLS implementation used by the dependent reqwest crate.

  • Implement a reset mechanism for mutable resources returned to a pool (ResourcePool) to keep it in a consistent state.

  • Implement a lock mechanism on SignedEntityType to prevent concurrent work on a same entity type.

  • Extended CI build and test steps for MacOS arm64 runners and include pre-built binaries for MacOS arm64 in the releases.

  • Add a regularly run upkeep task to the mithril-aggregator and mithril-signer to clean up stale data and optimize their databases.

  • Support for Cardano node 9.0.0 in the signer and the aggregator.

  • Refactor the Cardano node configuration in the infrastructure.

  • Add prettier configuration to standardize the code formatting in the repository.

  • Field beacon becomes optional in CertificatePendingMessage response of /certificate-pending route.

  • UNSTABLE Cardano transactions certification:

    • Optimize the performances of the computation of the proof with a Merkle map.
    • Handle rollback events from the Cardano chain by removing stale data.
    • Preload Cardano transactions and Block Range Roots at signer & aggregator startup.
    • Chunk the Cardano transactions import in mithril-signer to reduce disk footprint by running the pruning process more frequently.
    • Add a database connection pool on the Cardano transaction repository for increased performances of the prover.
    • Import Cardano transactions with Chain Sync mini protocol and Pallas chain reader.
    • Avoid aggregator and signer being blocked when importing the Cardano transactions.

  • Crates versions:

Crate Version
mithril-aggregator 0.5.40
mithril-client 0.8.7
mithril-client-cli 0.9.6
mithril-client-wasm 0.3.7
mithril-common 0.4.29
mithril-signer 0.2.161
mithril-stm 0.3.24

Mithril Distribution [2423.0] - 2024-06-12

  • BREAKING changes in Mithril client CLI:

    • The deprecated snapshot command is removed from the Mithril client CLI
    • Use the cardano-db snapshot command instead.

  • Update website and explorer user interface to use the new mithril logo.

  • UNSTABLE Cardano transactions certification:

    • Support computation of the Cardano Transactions signature and proving with the pre-computed Block Range Merkle Roots retrieved from the database.
    • Prune Cardano Transactions from the signer database after the Block Range Merkle Roots have been computed.
    • Implement a Chain Reader which retrieves blocks from the Cardano chain with Pallas through the chainsync mini-protocol.
    • Implement a Resource Pool and use it for caching Block Range Merkle maps used by the Cardano transactions prover and improving the throughput.
    • Change the beacon of the Cardano Transactions to a block number instead of an immutable file number.

  • Crates versions:

Crate Version
mithril-aggregator 0.5.16
mithril-client 0.8.3
mithril-client-cli 0.9.2
mithril-client-wasm 0.3.3
mithril-common 0.4.13
mithril-signer 0.2.141
mithril-stm 0.3.22

Mithril Distribution [2418.1] - 2024-05-13

  • BREAKING changes in Mithril client CLI:

    • Certificate chain structure has been modified to remove coupling with immutable file number.
    • Client needs to be updated to verify certificate chain.

  • Support incremental import for Cardano Transactions instead of scanning the whole immutable database for every signing round.

  • Chain observers support the retrieval of the current Cardano chain point.

  • Deprecate portable feature of mithril-stm and mithril-client:

    • Instead, always enable BLST portable feature in mithril-stm for runtime check of intel ADX instruction set.
    • portable feature now has no effect and should be removed from crate dependencies.
    • Removed it from all other crates (including mithril-common).

  • Switched memory allocator to jemallocator on signer and aggregator to avoid memory fragmentation when signing transactions (which lead to RES memory not being properly returned to the OS).

  • Crates versions:

Crate Version
mithril-aggregator 0.5.0
mithril-client 0.8.0
mithril-client-cli 0.8.0
mithril-client-wasm 0.3.0
