LAST WEEK’S Top Commits

Last week, we implemented concurrent transactions packing & verification in PEE branch. We record transactions based on their dependencies on a directed acyclic graph (DAG), and then verify these transactions based on this DAG. We implemented MVCCDB to support the concurrent transactions packing. In addition, We also did the first round of comprehensive testing based on our testnet, includes execution of transactions, deployment and invocation of smart contracts, and parameters validation of RPC interface.

Summary this week is as following,


  • Implemented concurrent transactions packing & verification;
  • Implemented mvccdb to support the concurrent transactions packing;


  • Perfected transaction and smart contract testing;
  • Added rpc test cases;


  • Released go-nebulas v0.6.1(Fixed the problem caused by the change of the block storage structure).
