Deprecated software
This is a list of key Ethereum-related projects and resources which have been deprecated or are no longer maintained. It is important to highlight deprecated work so that users can find viable alternatives and to prevent malicious versions from being distributed.
This list is curated by our community. If there's something missing or incorrect, please edit this page!
Proof-of-work
Proof of work is a consensus engine that was implemented in Ethereum until September 2022. It was deprecated when Ethereum swapped to a proof-of-stake based consensus mechanism. This was achieved by deprecating the parts of the client software related to proof-of-work mining, including Ethhash (the mining algorithm) and all the consensus logic and block gossiping functionality that was originally built in to execution clients. The clients themselves were not deprecated but several of their core components were. The concept of proof-of-work was deprecated as the total effect of removing the related components of the client software.
Software
This section is for software for the desktop, command line, or server which has been deprecated. The main types are wallets, integrated development environments, languages, and Ethereum clients. Definitely be careful to not install deprecated software unless you are certain it is from the original source, e.g. a repo hosted under https://github.com/ethereum(opens in a new tab).
OpenEthereum
Deprecated July 2021
Summary

OpenEthereum played an important role in being a key piece of infrastructure for some of the largest users in Ethereum like Etherscan and Gnosis Safe. Its tracing capabilities set it apart from other clients, ensuring reliable and fast synchronization for data providers.
