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.
Manta is the universal private blockchain platform provides end-to-end privacy protection for blockchain users through leading cryptography architectures such as zkSNARK. Manta's zero-knowledge cryptography allows developers to build dapps and users to conduct private transfers and transactions between any parallel chain of assets.
StarkWare is a ethereum layer-2 scaling protocol and one of main zk-rollup solutions. Starkware builds StarkNet( a permissionless decentralized ZK-Rollup) and StarkEx(a standalone permissioned Validity-Rollup）, both layer-2 scaling solutions for Ethereum using zero-knowledge rollup technology.
Dymension's blockchain platform is a modular settlement layer which provides all the tools and infrastructure needed to easily launch enshrined rollups as part of the Cosmos eco-system. Opening a whole new dYmension of decentralized use cases. dYmension introduces a scaling paradigm shift, enabling a future where metaverse apps, games and other ultra-TPS services can reside on the blockchain by easily deploying dedicated rollups customized for their needs.
