What's Changed

Please note this release is not backward-compatible with previous releases.

• You will not be able to connect to the Phase 2 testnet network with this version or access your Phase 2 chain or accounts using this version.
• If you've earned Phase 2 testnet points, we recommend running ironfish accounts:export on an older version to back up your account keys.

Network definitions

Previously, network parameters like the genesis block and bootstrap nodes were built into the code, but in this release @mirayadav added support for network definitions, which allow the CLI to support multiple networks.

We'll eventually use this feature to run mainnet and testnet using the same CLI. You can pass --customNetwork to the start command if you'd like to create your own network, or pass --networkId with the ID of one of the networks in this file: https://github.com/iron-fish/ironfish/blob/38d2528903d3def6be0eaa4eaf400deb541b404c/ironfish/src/defaultNetworkDefinitions.ts

Add sender to transactions

Transactions now display the public address from which they were sent. Transactions still allow multiple recipients, but for now, we're limiting transactions to a single sender to support this feature.

Adding transaction commitment to block header

Block headers now contain a merkle root of all transactions in the block, allowing block recipients to verify that they've received the matching transactions for the block.

Reducing network and storage usage

We removed some unnecessary fields from the database and block header to save disk space and network usage.

Continuing work on multi-asset support

Multi-asset support is not yet usable in the CLI, but the underlying fields and circuits are nearly complete.

Change in data directory structure

We've changed the folder structure of our data directory to make it clearer which folders contain databases and which folders contain configuration.
