BTCPool v2.1.0.1 for UBTC (bug fix)
Fix: if UB's root_state_hash is empty, default_root_state_hash
from UB's getblocktemplate
will be 00f9
, and jobmaker
will not put it into coinbase transaction, then UB may reject the block.
Now, any content >= 4 characters (2 bytes in binary) in default_root_state_hash
will be put into coinbase transaction as a output.
