Ethereum co-founder Vitalik Buterin tweeted on the 19th that he is looking forward to the potential benefits of Verkle Trees in Ethereum. He pointed out that the application of Verkle trees will make stateless verification clients possible, which means that verification nodes can run with almost no hard disk space and can synchronize in almost real time.
What are Verkle Trees?
Everyone in the currency circle may be more familiar with the Merkle Tree, and Verkle Tree is an evolved form of this technology, aiming to improve the efficiency of data storage and indexing. Verkle Trees use vector commitments and other mathematical techniques to make data storage more compact while maintaining data verifiability.
Imagine that the blockchain is like a huge ledger that records all transactions and operations. Whenever there is a new transaction, it must be recorded in this ledger. Typically, to confirm that these records are correct, you need to have a copy of the entire ledger, which requires a lot of storage space and processing power.
Now, with the new technology of Verkle Trees, Ethereum can achieve "stateless verification". This means that even if you don’t have a copy of the entire ledger, you can confirm that transactions are correct. All you need is a small file, which is like a summary of a page in the ledger and contains all the necessary information to confirm the correctness of a particular transaction.
This has many benefits, such as saving a lot of storage space and making the entire blockchain network run more efficiently. At the same time, in order to make this approach feasible, Ethereum has proposed a new rule: charging based on the resources you use. Like, the more pages of the ledger you read, the more you pay.
Target to launch the mainnet in 2024
According to official documents, Verkle Trees aims to launch the Ethereum mainnet this year. The specific time has not yet been announced. Vitalik also said that after the launch in the future, for individual pledges It will also be a huge improvement for the user experience. At the same time, it is also very beneficial for user-oriented lightweight clients.
The above is the detailed content of What are the Verkle Trees that Buterin praised so much? The goal is to launch the Ethereum mainnet this year. For more information, please follow other related articles on the PHP Chinese website!
