Odaily News Covalent Network (CXT), a blockchain data infrastructure, recently announced the launch of the Ethereum Time Machine (EWM) light client testnet. This move aims to protect the decentralized nature of Ethereum while addressing the historical data storage challenges brought about by network expansion. The EWM light client allows users to participate in the verification and preservation of Ethereum's historical data through ordinary laptops, effectively preventing the risk of data centralization. The testnet is now open, and participants can receive exclusive rewards and enter the mainnet stage with an expected annualized rate of return of 20-25%. Covalent Network (CXT) will contact verification participants in batches, and users who have registered for the waiting list are advised to pay close attention to their mailboxes for follow-up instructions.
