Autonity Staking

Newton (NTN) is the native staking token of the Autonity network. It is the primary instrument used in Autonity's Proof-of-Stake consensus mechanism. Token utilities include:

• Staking: Users bond NTN to validators to secure the network and earn inflation rewards distributed every 30-minute epoch.
• Liquid Staking: When delegating NTN, you automatically receive Liquid Newton (LNTN) tokens — protocol-native liquid staking derivatives that represent your staked position.
• Governance: Staked NTN grants participation in network governance.

NTN has a maximum supply of 100 million tokens. Note: Autonity also has a separate gas token called Auton (ATN) used for transaction fees.

Autonity is an EVM-compatible Layer 1 blockchain designed for decentralized derivatives markets. It uses Tendermint BFT consensus with Delegated Proof of Stake and launched its mainnet in August 2025. Key features:

• Dual-Token Model: ATN (Auton) for gas fees and NTN (Newton) for staking — separating utility and security functions.
• Protocol-Native Liquid Staking: Delegators automatically receive LNTN tokens when bonding NTN, without needing third-party liquid staking providers.
• Epoch-Based Rewards: Staking rewards are distributed every 30 minutes (1,800-second epochs).
• 1-Second Block Time: Ultra-fast block production for derivatives trading.
• Committee-Based Consensus: Top validators by bonded stake form a consensus committee of up to 27 members.

Autonity aims to create a logically decentralized environment for price discovery and trade execution of smart derivative products.

Autonity uses a dual-token model with deterministic inflation:

Newton (NTN) — Staking Token:

• Maximum Supply: 100,000,000 NTN (hard cap)
• Current Total Supply: ~62 million NTN
• Circulating Supply: ~40 million NTN
• Inflation Reserve: ~38 million NTN (released gradually as staking rewards)
• Treasury Fee: 5% of epoch rewards go to the protocol treasury

Auton (ATN) — Gas Token:

• Used exclusively for transaction fees on the network
• Transaction fee rewards are distributed to consensus committee validators

NTN inflation is deterministic: each epoch, the InflationController contract calculates new NTN to mint from the reserve. As the reserve depletes, per-epoch emissions decrease, approaching the 100M hard cap asymptotically.

Autonity uses Tendermint BFT (Byzantine Fault Tolerant) consensus with Delegated Proof of Stake. Key parameters:

• Block Time: 1 second
• Epoch Period: 1,800 seconds (30 minutes) — rewards distributed per epoch
• Maximum Committee Size: 27 validators
• Unbonding Period: 21,600 blocks (~6 hours)
• Finality: Instant (single-slot finality via BFT)

The consensus committee is formed by the top validators ranked by total bonded stake. Committee members produce blocks and earn both ATN fee rewards and NTN inflation rewards. Validators outside the committee still earn NTN inflation rewards proportional to their stake.

The protocol is EVM-compatible, meaning Ethereum smart contracts and tooling work natively on Autonity.

To stake NTN tokens and earn rewards:

1. Acquire NTN: Obtain Newton (NTN) tokens.
2. Choose a Validator: Select a validator from the Autonity staking page. Review their commission rate, bonded stake, and active status.
3. Bond NTN: Delegate your NTN to the validator. You will automatically receive Liquid Newton (LNTN) tokens representing your staked position.
4. Earn Rewards: NTN inflation rewards are distributed every epoch (30 minutes). Your rewards accrue proportionally to your bonded stake.

Autonity currently has 30 registered validators with 16 actively participating in consensus. All validators currently charge a 10% commission rate.

When selecting an Autonity validator, consider:

• Active Status: Only validators in the ACTIVE state (not paused, jailed, or jailbound) are reliably earning rewards. Check the validator's state on the staking page.
• Committee Membership: Validators in the consensus committee (top by bonded stake, max 27) earn additional ATN fee rewards on top of NTN inflation.
• Commission Rate: Currently all validators charge 10%, but this may change over time.
• Self-Bonded Stake: Validators with more self-bonded NTN have greater skin in the game. Self-bonded stake is slashed first in case of misbehavior, protecting delegators.
• Slashing History: Check if the validator has been previously slashed or jailed for inactivity.

Autonity staking rewards come from two sources:

• NTN Inflation Rewards: Every epoch (30 minutes), the on-chain InflationController contract calculates new NTN to mint from the inflation reserve. After deducting a 5% treasury fee, the remaining rewards are distributed to all stakers proportionally to their bonded NTN.
• ATN Fee Rewards: Transaction fees paid in ATN are redistributed to consensus committee validators. These are variable and depend on network activity.

The reward rate is calculated as: (supplyDelta × epochsPerYear) × (1 - treasuryFee) / totalBondedStake. The inflation reserve started at 40 million NTN and depletes over time, causing per-epoch emissions to gradually decrease. Higher staking ratios reduce the per-staker yield, creating a natural equilibrium incentive.

Liquid Newton (LNTN) is Autonity's protocol-native liquid staking token. Unlike other networks where liquid staking requires third-party protocols, Autonity builds liquid staking directly into the base layer:

• Automatic Issuance: When you delegate NTN to a validator, you automatically receive LNTN tokens.
• Per-Validator: Each validator has its own LNTN contract, so LNTN from different validators are separate tokens.
• Conversion Ratio: The NTN/LNTN exchange rate is tracked on-chain per validator and may change due to slashing events.
• Self-Bonded Exception: Validator self-bonded stake does NOT receive LNTN — this is by design to ensure validators have direct skin in the game (self-bonded stake is slashed first).

Consider these risks when staking NTN on Autonity:

• Slashing Risk: Validators can be slashed for misbehavior or prolonged inactivity. Self-bonded stake is slashed first, providing some delegator protection, but delegated stake can also be affected.
• Jailing Risk: Validators can be jailed for inactivity, during which time they do not earn rewards. If your validator is jailed, you should redelegate to an active validator.
• Short Unbonding Period: The unbonding period is only ~6 hours (21,600 blocks), which is relatively short compared to other networks. This means less lock-up risk but also faster potential for validator stake changes.
• Early Network Risk: Autonity mainnet launched in August 2025. As a relatively new network, there is inherent risk of undiscovered bugs or protocol issues.
• Price Risk: NTN does not yet have established market pricing on major exchanges. Liquidity may be limited.

This is not an exhaustive list. Always do your own research before staking.
