Distribution 2517 is now available​

warning
  • This distribution embeds a fix for the Mithril snapshots for Cardano database could be compromised by an adversary security advisory GHSA-qv97-5qr8-2266
  • All users running a client library or client CLI are strongly encouraged to update to the latest versions.
Update 2025/05/06

The team released the hotfix 2517.1 to address a bug in the 2517.0 distribution that caused the Cardano node to fail during startup when using a snapshot downloaded with the Mithril client.

The 2517.1 distribution has been released, introducing the following changes:

  • ⚠️ Breaking changes in Mithril client CLI and library:
    • To fast bootstrap a Cardano node, the new --include-ancillary option has been added to the Cardano node database command in the Mithril client CLI.
    • Without this option, only final immutable files are downloaded, and the ledger state must be computed from the genesis block when the Cardano node starts.
    • The --include-ancillary option requires the usage of an ancillary verification key (--ancillary-verification-key or ANCILLARY_VERIFICATION_KEY) which is specified in the Networks configuration page.
    • Clients from distribution [2513] and earlier are not compatible with this change and must be updated.
  • Support for Cardano node 10.3.1 in the signer and the aggregator
  • Support for origin tags in Mithril client library, CLI and WASM to record the origin of client requests.
  • Bug fixes and performance improvements.

This new distribution has been deployed to the Mithril aggregator on the release-mainnet and release-preprod networks.

If you are running a Mithril signer:

  • pre-release-preview network: no action is required at this time
  • release-preprod network: upgrade your signer node binary to version 0.2.243 – no configuration updates are required
  • release-mainnet network: upgrade your signer node binary to version 0.2.243– no configuration updates are required.

You can update the Mithril signer using the one-line command below. It downloads to the current directory by default, but you can specify a custom folder using the -p option:

curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/input-output-hk/mithril/refs/heads/main/mithril-install.sh | sh -s -- -c mithril-signer -d 2517.1 -p $(pwd)
