AltLayer introduces an open and decentralized protocol for rollups, amalgamating a novel concept of Restaked Rollups. These rollups, derived from various rollup stacks such as OP Stack, Arbitrum Orbit, Polygon CDK, ZK Stack, etc., are endowed with heightened security, decentralization, interoperability, and rapid crypto-economic finality through the innovative restaking mechanism. ALT serves as the native utility token of AltLayer and fulfills several essential functions: Economic Bond: ALT tokens, alongside restaked assets, form an economic stake, subject to potential slashing in case of detected malicious behavior. Governance: ALT token holders possess the right to vote on governance decisions. Protocol Incentivization: Operators within the AltLayer ecosystem can earn ALT tokens as rewards for their services. Protocol Fees: Network participants are required to pay for intra-network services using ALT tokens. AltLayer's core suite of restaked rollups comprises three primary products: VITAL: An Actively Validated Service (AVS) where operators verify blocks and corresponding states committed by the rollup sequencer, and issue fraud proof challenges if necessary. MACH: A protocol designed to expedite finality for rollups by enabling operators to restake Ethereum-based assets to support any claims on the rollup state. SQUAD: Provides decentralized sequencing with economic backing, mitigating short-term liveness concerns, negative MEV, rent extractions, and other issues associated with single sequencer-operated rollups. AltLayer has successfully raised 22.8 million USD through two rounds of private token sales, with 18.50% of the total ALT token supply sold at 0.008 USD/ALT and 0.018 USD/ALT, respectively. Prominent investors in AltLayer include Polychain Capital, Binance Labs, Jump Crypto, Breyer Capital, DAO5, Balaji Srinivasan, Gavin Wood, Sean Neville, Ryan Selkis, among others. As of January 17th, 2024, the total supply of ALT amounts to 10,000,000,000 tokens, with a circulating supply upon listing set at 1,100,000,000 (11.00% of the total token supply).
