Nebulas Mainnet Development

Nebulas Blockchain Runtime Environment（NBRE）

We finished functional verification of Nebulas Blockchain Runtime Environment(NBRE), updated the data structure for blocks on blockchain, and completed JIT (just-in-time) environment based on LLVM which should be a good base for updating Nebulas Rank(NR) and Developer Incentive Protocol(DIP) online.

API Functionality Extension

Based on the requirement from exchanges, we extended the functionalities of some APIs, which include the block height information within the transaction. This change has already deployed to Nebulas mainnet.

About the Issues on Testnet

We also fixed the synchronization issue caused by the deployment of inter-contract call functionality on the testnet, more specifically, the latest error handling logic in V8 is not compatible with the old transactions.
