17278/what-regex-to-use-to-identify-a-block-hash
I'm trying to identify if a URL component includes a bitcoin block hash, which looks like 000000000d32098b5faf86d17cb6e1828ac98f3b104f019dd78bfc9fdc1ae7b0
I wanted to know what regex I can use to identify this. Can somebody help me out?
Blockhashes are always 64 characters in length.
You can use the following regex to identify the block hash
/^[0-9a-f]{64}$/i
