developing • Combine usability & performance • Work nicely with Xcode Playground, support macOS & Ubuntu currently Playground “Script Language Feeling” is very important for usability. WTF it is ??? performance. • Strongly optimized. Cons: • Hardly debug. (can’t print intermediate value) • Poor usability. Now, we have the Third mode TFiwS Mode let x : Tensor = [[1,2,3], graph, feeling like eager execution. • This is the key to enable natural control flow and debug usability • Therefore, we can’t. Direct bridging is exactly traditional graph mode. Not TFiwS mode. WTF

zero-knowledge proof, group signature, ring signature as open projects to the public. In terms of usability, FISCO BCOS is designed to run at 7 * 24 hours to achieve a high availability needed for the commercial identity and transfer to Follower. 3.2 Block replication Raft protocol strongly depends on the usability of Leader to ensure consistency of group data, because data can only be transferred from Leader change. With the technological development, people start to concern about the performance and usability of executor. On one hand, they want faster execution speed of smart contract on blockchain to meet

Currently, FISCO BCOS adopts executor abstracted through EVMC of traditional EVM—Interpreter. So
