In Geth from version 1.9.4 and before version 1.9.20 a consensus-vulnerability could cause a chain split, where vulnerable versions refuse to accept the canonical chain. The fix was included in the Paragade release version 1.9.20. No individual workaround patches have been made -- all users are recommended to upgrade to a newer version.</p> <p>Go Ethereum, or &#34;Geth&#34;, is the official Golang implementation of the Ethereum protocol.
