The post Paradigm offers solution to bug in its Reth Ethereum client appeared on BitcoinEthereumNews.com.

Paradigm chief technological officer Georgios Konstantopoulos has disclosed a bug in the firm’s Ethereum execution client Reth. In a post on X, Konstantopoulos stated that the bug is causing several nodes to stall while offering a solution to the problem. According to Konstantopoulos, users can fix the issue by running a set of commands that will get them past the bug without causing any major impact on their operations. He added that the fix would take about 45 minutes to complete, but he noted that the incident remains under investigation. He said: “We are still investigating root cause, but the above gets you past the issue. This is safe to run on both pruned & archive nodes, won’t lose you any RPC information, and will take ~45m to rebuild the trie before it continues syncing.” The bug was in the state root computation for Reth, which meant the client could not validate new blocks, effectively failing to synchronize with the Ethereum network. According to Paradigm, the issue reared its head at block 2327426 and affected Ethereum mainnet versions 1.6.0 and 1.4.8. Reth is a client on the Ethereum mainnet, which was built using the Rust language. Like other execution clients, including Geth, Nethermind, Go-ethereum, and others, it is responsible for running smart contracts and transactions on the mainnet. Meanwhile, Konstantopoulos described the incident as a brutal moment for the crypto research firm while adding that it will also serve as a learning curve. Paradigm has been pushing for accelerated development on Ethereum and presents its Reth client as a software development kit for building EVM-core nodes in a post earlier this year. Interestingly, the incident has also ignited conversations around Ethereum client diversity and decentralization. The Paradigm-built Reth is the newest execution client on Ethereum and is one of the…
