P2P Network

Implement the function of active request for downloading. In the downloader module, downloading and processing header process has been debugged.

PalletOne Consensus

Complete the function of mediator node periodically producing unit.

 Consensus

Discuss the design and implementation process of BFT consensus and mediator node rotation.

Transaction

Fix the bug about transaction creation and testing signature unit.

Transaction

Test the function of fetching UTXO through addresses.
