  • SegWit has been activated on mainnet since block 5805000.
  • Changed DeserializerBlackcoin to DeserializerBlackcoinSegWit.
  • Add correct fee value for mainnet.
  • add BLK block and transaction tests.
  • passes CI
  • Already running in production.

Electrum-BLK v4.8.0 uses Electrum Protocol 1.6 and needs incrementalrelayfee value.
Blackcoin has no RBF features, and 'getmempoolinfo' is missing the field. Without modifying the main code, it is better to create a specific BlackcoinDaemon class. and add Blackcoin specifics there. Also for future changes
