AltLayer (ALT) is a platform that can be used to launch native and re-staking Rollups, supporting Optimistic and ZK Rollup stacks.

AltLayer is an open and decentralized protocol designed for rollups. AltLayer brings a novel idea - re-staking Rollups, which takes rollups from any rollup stack (such as OP Stack, Arbitrum Orbit, Polygon CDK, ZK Stack, etc.) and provides them with enhanced security by leveraging the re-staking mechanism sex, decentralization, interoperability, and the rapid finality of the crypto-economy.

ALT is AltLayer’s native utility token and is used for the following functions:

Economic Bonds: ALT tokens will be used along with re-hypothecated assets to provide economic collateral. This stake can be reduced if malicious behavior is detected.

Governance: ALT token holders can vote on governance issues.

Protocol Incentives: Operators in the AltLayer ecosystem can receive ALT tokens as rewards for their services.

Protocol fees: Network participants need to use ALT tokens to pay for services within the network.

AltLayer's core product - re-pledged rollups, consists of three key products:

VITAL: An Active Verification Service (AVS) where the operator verifies blocks and corresponding states submitted by rollup sequencers and raises fraud proof challenges if necessary.

MACH: A protocol that provides faster rollups finality by allowing operators to re-stake Ethereum-based assets to back any claim to rollup status.

SQUAD: Provides decentralized sorting with economic support. Decentralized ordering eliminates short-lived issues, bad MEV, rent extraction, and other problems associated with rollups operated by a single sequencer.

AltLayer raised $22.8 million through two rounds of private token sales, in which 18.50% of the total ALT token supply was sold at prices of $0.008/ALT and $0.018/ALT.

AltLayer’s investors include Polychain Capital, Binance Labs, Jump Crypto, Breyer Capital, DAO5, Balaji Srinivasan (former Coinbase CTO and former a16z global partner), Gavin Wood (co-founder of Ethereum and Parity) , Sean Neville (co-founder of Circle and architect of USDC) and Ryan Selkis (founder of Messari), etc.
