blockchain-demo-platform's Issues

Fix fee transactions

Currently, when you add fee to a transaction, it goes missing because no OutputTransaction is created. Total amount of "cash" in blockchain decreases by given fee amount and the miner does not get the fee for himself

Blockchain graph error while rejoining the network

I got the error:
[2019-10-14 22:11:11] [WARNING] Error while generating blockchain graph Added node: 00000d50a8aea7342af00d34c8bc1b39780da3984d45fd4f80d2d0488e5e23d3 [2019-10-14 22:11:11] [WARNING] Error while generating blockchain graph after leaving the network and then entering again. It was a continuous stream of errors and the blockchain graph was not displayed at all.
