Key facts

  • 2023-06 mainnet launch
  • TVL 150 億+ USD (as of 2025 )
  • 40+ AVS in operation (EigenDA / Hyperlane / AltLayer / Espresso / Lagrange, etc.)
  • EIGEN token launched 2024-10 · used for inter-subjective dispute resolution
  • Slashing mechanism activated 2025 —— AVS can custom-define slashing conditions

Restaking Mechanism and AVS Workflow

Traditional cryptoeconomic security has a bootstrapping problem: a new L1 must launch BFT through staking of its native token, but in the early launch phase the token’s market cap is low → the cost of attack is low → no one dares to use it. “Middleware” such as cross-chain bridges / oracles / DA layers also requires its own independent validator set, and each must gather staking capital, which is extremely inefficient.

EigenLayer’s solution: “lease out” ETH, the deepest staking pool, to any service that needs BFT-style verification. Stakers earn additional yield, new services gain immediate security, and Ethereum L1 takes no damage (dual slashing guarantee) (see Liquid Staking + Restaking Ecosystem + CEX Exposure).

Analogy: SWIFT “lends” the KYC banking network it already has to a new payment company, rather than having each one build it individually.

Core components:

  • Operators: node operators who stake ETH (their own or as proxy for others) and selectively opt in to each AVS
  • AVS: services that need external verification, defining their own slashing conditions
  • EigenPods: contracts that receive ETH staking rewards, allowing native restaking
  • Strategies: support restaking of LSTs (stETH, rETH, cbETH, etc.)

Origin & evolution

EigenLayer was proposed in a restaking paper by Sreeram Kannan’s team (a former UW professor) in 2021 年, and launched its mainnet in 2023-06 . Its initial positioning was as “the security layer for the modular-blockchain era,” with target customers being Celestia competitors (EigenDA), cross-chain bridges (Hyperlane), and shared sequencers (Espresso).

In 2024-10 it launched the EIGEN token and introduced the concept of inter-subjective dispute resolution —— when there is a “subjective” violation in an AVS (such as an oracle quote diverging from the market, which cannot be cryptographically disproven), EIGEN holders vote on whether to slash. After activating slashing in 2025 , EigenLayer shifted from a “commitment mechanism” to an “actual economic-security market” (contrasted with the evolution on the crypto-native side in The Blockchain Industry Has Split at the DNA Level into \"On-Chain Finance\" and \"Crypto\").
