⁽*⁾⚠️ Linux arm64 builds are provided on a best-effort basis and are not officially supported.

Linux Requirements

The Linux binaries target glibc: to run them or install the .deb packages you must have glibc version 2.35+ installed.
Compatible systems include, but are not limited to, Ubuntu 22.04+ or Debian 12+ (Bookworm)).

Download a binary asset

To simplify the installation and updating of Mithril binaries, we have created a one line installer that downloads and installs the Mithril binaries for you.
This installer is available for Linux and macOS and supports the Mithril signer, Mithril aggregator, and Mithril client CLI.

Use the following commands to install the Mithril nodes:

• Download the Mithril signer in the current directory:

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 2543.0-pre -p $(pwd)

• Download the Mithril client CLI in the current directory:

curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/input-output-hk/mithril/refs/heads/main/mithril-install.sh | sh -s -- -c mithril-client -d 2543.0-pre -p $(pwd)

• Download the Mithril aggregator in the current directory:

curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/input-output-hk/mithril/refs/heads/main/mithril-install.sh | sh -s -- -c mithril-aggregator -d 2543.0-pre -p $(pwd)

Verify the authenticity of a downloaded asset

Detailed procedure to verify an asset

• Step 1: Identify the downloaded asset on your computer YOUR_ASSET_FILE
• Step 2: Download the signed checksum file from this link CHECKSUM.asc and save it in the same folder as the asset
• Step 3: In your terminal, go to the asset folder by running:

cd ***YOUR_ASSET_FOLDER***

• Step 4: Then verify the checksum of the asset by running:

sha256sum -c ./CHECKSUM.asc 2>/dev/null | grep ***YOUR_ASSET_FILE***

You must see:

./***YOUR_ASSET_FILE***: OK

• Step 5: Download the public key file from this link public-key.gpg and save it in the same folder as the asset
• Step 6: Then import the GPG public key:

gpg --import ./public-key.gpg

You must see something like:

gpg: key : public key "Input Output / Mithril <[email protected]>" imported
gpg: Total number processed: 1
gpg:               imported: 1

• Step 7: Then verify the GPG signature of the checksum file:

gpg --verify ./CHECKSUM.asc

You must see something like:

gpg: Signature made Mon 05 Dec 2022 04:53:54 PM CET
gpg:                using RSA key 35EDE9D47BBA62A2F388E655899ACD26B8BCA0D2
gpg: Good signature from "Input Output / Mithril <[email protected]>" [unknown]
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: 35ED E9D4 7BBA 62A2 F388  E655 899A CD26 B8BC A0D2

The signature is valid if and only if:

• there is a line with gpg: Good signature from "Input Output / Mithril <[email protected]>"
• there is a line with Primary key fingerprint: 73FC 4C3D FD55 DBDC 428A D2B5 BE04 3B79 FDA4 C2EE

• Step 8:
  If you successfully validated all the steps of this process, then you have successfully verified the authenticity of the asset ✔️
  If not, contact us at [[email protected]] and let us know of the outcome of your run of this process ⚠️

Mithril v2517.1

Highlights

Warning

🔥 This version fixes a bug in the 2517.0 distribution which caused the Cardano node to fail during startup when using a snapshot downloaded with the Mithril client.

Make sure you are using the Mithril client CLI with version 0.12.1.

• ⚠️ Breaking changes in Mithril client CLI and library as detailed in this blog post:
  • 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.

Verify the authenticity of a downloaded asset

Detailed procedure to verify an asset

• Step 1: Identify the downloaded asset on your computer YOUR_ASSET_FILE
• Step 2: Download the signed checksum file from this link CHECKSUM.asc and save it in the same folder as the asset
• Step 3: In your terminal, go to the asset folder by running:

cd ***YOUR_ASSET_FOLDER***

• Step 4: Then verify the checksum of the asset by running:

sha256sum -c ./CHECKSUM.asc 2>/dev/null | grep ***YOUR_ASSET_FILE***

You must see:

./***YOUR_ASSET_FILE***: OK

• Step 5: Download the public key file from this link public-key.gpg and save it in the same folder as the asset
• Step 6: Then import the GPG public key:

gpg --import ./public-key.gpg

You must see something like:

gpg: key : public key "Input Output / Mithril <[email protected]>" imported
gpg: Total number processed: 1
gpg:               imported: 1

• Step 7: Then verify the GPG signature of the checksum file:

gpg --verify ./CHECKSUM.asc

You must see something like:

gpg: Signature made Mon 05 Dec 2022 04:53:54 PM CET
gpg:                using RSA key 35EDE9D47BBA62A2F388E655899ACD26B8BCA0D2
gpg: Good signature from "Input Output / Mithril <[email protected]>" [unknown]
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: 35ED E9D4 7BBA 62A2 F388  E655 899A CD26 B8BC A0D2

The signature is valid if and only if:

• there is a line with gpg: Good signature from "Input Output / Mithril <[email protected]>"
• there is a line with Primary key fingerprint: 73FC 4C3D FD55 DBDC 428A D2B5 BE04 3B79 FDA4 C2EE

• Step 8:
  If you successfully validated all the steps of this process, then you have successfully verified the authenticity of the asset ✔️

Mithril v2517.0-pre

Highlights:

• ⚠️ 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.
