testnet invalid address

[liorko87]

I downloaded the latest version of the repo. I'm trying to mine locally on my computer. My bitcoin version is 0.21 (their latest release). At the start of the mining I received this error:

invalid address -- 'tb1quzy257p3d93zmt77fhaqf7nl68nv80vg4576j3'
Try `cpuminer-multi --help' for more information.

The error means the address was not correctly formatted for B58 encoding.

Did you get the same error with cpuminer-multi? If so I can't really help you. I don't know anything about B58 encoding so I have no idea what may be wrong with the address . I use the same code as cpuminer-multi which originated with the original cpuminer by pooler.

This address is SegWit address and encoded as bech32.

[JayDDee]

Cpuminer is old code that predates segwit. Mining BTC with a CPU is long obsolete so there isn't a good reason to try to support it.

Bech32 is used by other algos. Follow issue #307 for updates.
