✨
Tl;dr: Verkle Trees and statelessness bring many benefits to Ethereum
  • Smaller proof sizes allow proofs to be passed over the network, which will unlock many new types of functionality in addition to stateless clients
  • Lower hardware requirements to run a node, which improves decentralization
  • New nodes can join the network right away with faster sync
  • Potential scaling benefits in that it could allow for higher gas limits
  • More compatible with a zk-EVM future

💡

Bringing Verkle into Ethereum involves many changes in the protocol:

  • A new data structure to save the state of the network
  • A new gas accounting model
  • A strategy to migrate the existing state from the MPT to the VKT
  • A new set of cryptography primitives
  • New fields at the block level
