In December 2016, the forum for the public blockchain-based distributed computing platform Ethereum suffered a data breach . The database contained over 16k unique email addresses along with IP addresses, private forum messages and (mostly) bcrypt hashed passwords. Ethereum elected to self-submit the data to HIBP , providing the service with a list of email addresses impacted by the incident.
