This release is functionally equivalent to v1.1.1 but includes hardcoded configuration for the Autonity Mainnet.
To get started on mainnet, just run ./autonity.

We are excited to announce the release of Autonity Go Client version 1.1.1, designed to support the Bakerloo Testnet, which mirrors the upcoming Autonity Mainnet. This release introduces critical features and enhancements to ensure compatibility, performance, and stability for validators and developers preparing for the mainnet launch.

We've introduced a clustering model for efficient message routing within the consensus network. While maintaining full mesh connections, nodes are now organized into clusters with designated roles: Originator, First Relayer (Origin/Remote Cluster), and Local Relayer (Origin/Remote Cluster). Combined with BLS signature aggregation, this clustering enables our consensus protocol to scale to 500 validators, processing up to 1,000 transactions per second (TPS) in testing. Further optimizations are planned to boost performance and scalability.

Other additional updates include:

• ASMv2 : The Autonity Stabilization Mechanism has been upgraded to version 2, featuring a new auction mechanism.
• Delegated staking: New functionality to support delegated staking.
• Formal code audit: Issues identified in a formal audit have been resolved, with a report to be published soon.

Stay tuned for a detailed changelog and further information.

Autonity v1.0.2-alpha "Rome" marks a key milestone, supporting the pre-mainnet testnet "Tiber." Key features include:

• Consensus Omission Accountability: Validators in the epoch consensus committee are expected to actively participate. To encourage this, a portion of epoch rewards is allocated to active participants. Validators failing to meet the participation threshold may face jailing.
• Oracle Outlier Detection and Incentives: The Oracle protocol can now identify and exclude outlier reports from price calculations. Additionally, a portion of epoch rewards is dedicated to incentivizing accurate price reporting, similar to the consensus participation mechanism.
• Auto-Bonding of NTN Rewards: Instead of being claimable, NTN rewards are now automatically re-bonded to their respective validators, enabling an auto-compounding mechanism.

For more detailed informations please check out the Autonity documentation.

Autonity v0.14.1 is a hotfix release that addresses internal issues potentially causing a gradual slowdown in the consensus process. It's strongly recommended that validators upgrade to this patched version.

Autonity v0.14.0 is our latest release with some new features regarding the protocol economics. We're introducing NTN inflation rewards: all stakers are now entitled to inflation NTN tokens dynamically injected in the current supply and this using the same reward claiming circuit as ATN rewards. The inflation of staking token NTN is designed to keep the total supply capped to 100M NTN.
We're introducing as well a new feature for changing a validator enode information (ip and port) and in-protocol unlock contracts which can be in either staked or non-stakeable mode.
Finally, on a more fundamentally technical point, we have completed the switch to BLS signatures with a brand new signature aggregator component that should enable scaling up the consensus committee size.

For more information please look at our updated documentation.

⚠️ 0.14.0 is not backward compatible with any previous version of Autonity. A regenesis of the blockchain is required.

Autonity v0.13.0 marks a significant milestone in the history of Autonity, introducing several important modifications to the protocol.

• We've thoroughly redesigned our consensus protocol's mechanics at the network level by launching a specialized peer-to-peer network exclusively for the consensus committee: the "Consensus" network. This should boost the performance of the system and reduce mining rate fluctuations during periods of high transaction volume.
• We're initiating the deep integration of BLS signatures starting with an updated validator onboarding process and the replacement of the "nodekey" file with the "autonitykeys" file.
• We've also decoupled our discovery protocol from Ethereum's, aiming for quicker initial synchronization.
• We resolved numerous internal problems. This should substantially minimize slashing incidents, especially when rebooting validator nodes.
• Furthermore, we've introduced a novel governance feature that provides a universal on-chain mechanism for smart contract upgrades, accompanied by a new "jailbound" state for validators.

We highly recommend you to check our documentation for more information.
