Linea is a type 2 zero knowledge Ethereum Virtual Machine (zkEVM). A zkEVM replicates the Ethereum environment as a rollup and allows developers to build on it as they would on Ethereum mainnet. For users, this enables the experience and security guarantees of Ethereum, but with lower transaction costs.
Blast is an EVM-compatible, optimistic rollup that raises the baseline yield for users and developers without changing the experience cryptonatives expect. Blast is an Ethereum L2 with native yield for ETH and stablecoins. On Blast, users balance compounds automatically, and earns Blast rewards on top.
EigenLayer is a protocol built on Ethereum that introduces restaking, a new primitive in cryptoeconomic security. This primitive enables the reuse of ETH on the consensus layer. Users that stake ETH natively or with a liquid staking token (LST) can opt-in to EigenLayer smart contracts to restake their ETH or LST and extend cryptoeconomic security to additional applications on the network to earn additional rewards.
