About pk910.de

pk910 is the personal site of a DevOps engineer on the ethPandaOps team at the Ethereum Foundation, who runs the devnets and testnets that Ethereum upgrades are tested on before mainnet. Most of the work is open source, including PoWFaucet, the Dora beacon chain explorer, and the Assertoor and Spamoor testing tools. The engineer also started Ephemery, a testnet that resets to genesis on a fixed schedule.

Hosted services include community testnet ETH faucets for Sepolia, Hoodi and Ephemery, an Ephemery explorer, and a public Buildoor block builder instance on Hoodi. The site also links to IP Tools, a network information utility at ip-tools.eu.

Earlier work includes IRC daemons and services written in C and PHP, and about a decade of Microsoft 365 and SharePoint consulting at innobit ag between 2013 and 2021.

Product: Open-source Ethereum testnet tooling and public testnet faucets, including PoWFaucet, Dora, Assertoor, Spamoor and Ephemery.
