 In presence of the `SIGHASH_FORKID` flag in the signature's sighash type, the proposed algorithm is used.
 
-Signatures using `SIGHASH_FORKID` must be rejected before [UAHF](https://github.com/Bitcoin-UAHF/spec/blob/master/uahf-technical-spec.md) is activated.
+Signatures using `SIGHASH_FORKID` must be rejected before [UAHF](uahf-technical-spec.md) is activated.
 
 In order to ensure proper activation, the reference implementation uses the `SCRIPT_ENABLE_SIGHASH_FORKID` flag when executing `EvalScript` .
