Solo mining invalid coinbase address - does not support Bech32 format (Sugarchain)

[RytirFik]

Hi, it seams -coinbase-addr does not accept address generated as Bech32 in desktop wallet (Sugarchain Yumekawa v0.16.3.36). Probably the miner does not recognize the format of the address. I have tested Bech32 and without Bech32 format which works. Example1 address in Bech32: cpuminer-sse2.exe -a yespower -o http://127.0.0.1:34229 -u xx -p xx --coinbase-addr=sugar1q0jud5nntpwarlzv343q4kt6asp84ncwexfyth2 -t12 Miner report ** cpuminer-opt 3.16.1 *** A CPU miner with multi algo support and optimized for CPUs with AVX512, SHA and VAES extensions by JayDDee.

That is correct Bech32 isn't supported.

I could add it if it's not too much work and you can point me to a working implementation. I would also need someone to test it.

[RytirFik]

Thank you for info. Happy to test and give you feedback.

[JayDDee]

I found a Bech32 decoding implementation in Verthash miner. It's self contained and low risk. The code is only called if B58 decoding has failed.

It will be included in the next release untested as I don't have the ability to test solo mining. Assuming the code works, and no other changes are required to support Bech32 addresses, it should work transparently. Even if it doesn't work it shouldn't break anything

I'm working on some other changes as well so it won't be available for a few days.

cpuminer-opt-3.16.2 is released with added support for Bech32. Please test. Please add -D to command line options for testing as I have added a couple of new debug logs.

JayDDee, thanks! It looks it works. It took me longer than expected to get block there, therefore I am answering later. FYI part of miner with -D.

Thanks for testing. The key indicators are: the debug log confirming Bech32 addressing, the debug log confirming segwit was enabled, and most importantly a block was solved with that configuration. I'll take your word that you solved a block.
