fisco-smart's Introduction

Make Smart Contracts Smarter on Blockchain

Directories

- client: the implementation of client
- console: run client as terminal
- dist: experiment figures and a small NFT study case
- eval_logs: raw experiment data
- fisco-smart: the implementation of blockchain nodes and precompiled contracts
- gramine: Graphene-SGX LibOS code
- quote-verification: scripts for extracting the SGX quote file
- tee-provider: the implementation of TEE provider
- *.sh: bash scripts to install dependencies and run the prototype

Dependencies

FISCO-BCOS v3.0.0
gramine v1.2

Tips and possible issues

Switch source for faster compile

cat > ~/.gitconfig << EOF
[url "https://ghproxy.com/https://github.com/"]
        insteadOf = https://github.com/
[http]
        sslVerify = false
EOF

console v3.0.0 has minor issues on calling precompiled contracts, the fixed method refers to FISCO-BCOS/console#601.

Evaluation

estimated gas cost of model inference on-chain

time cost of TEE register, distributed attestation, and secret provisioning

time cost comparison in SMART and EVM-based on-chain solutions

end-to-end latency of SMART framework
