Espresso Network has officially transitioned to a permissionless proof-of-stake blockchain, with the ESP token now live. A community airdrop representing 10% of the total supply is being distributed, and participants can stake tokens to help secure the network. The total supply of ESP is 3.59 billion tokens, and the transition aims to bolster community involvement and improve network finality. Espresso’s unique focus on supporting layer-2 networks distinguishes it from traditional layer-1 solutions.
