nxt system should have a validation function to verify the account is available.
e.g:
acct: 209832084023840384023
MD5 & SHA Checksum: DfwSgeH
so the new account: DfwSgeH-209832084023840384023
Check the MD5 or SHA to verify the account available..
thanks for this example coolfish,
could you explain further please how this checksum approach can verify account available?
