tags: Starcoin Web3 StarTrek, Proof-of-work Generate nonce (random data) as salt to join to the data of block to be hash. The goal is to find a hash value that less than target. The target is influenced by difficulty. As the difficulty gets bigger and the target will be smaller, which means more difficult to find. pub fn difficult_to_target(difficulty: U256) -> U256 { U256::max_value() / difficulty }

tags: Starcoin Web3 StarTrek Why compile starcoin from source? Why not download a released binary? Because I want to contribute code to it, maybe in the future. But the toolchain is awesome, the progress is very simple. Just two steps: Clone the code from GitHub git clone git@github.com:starcoinorg/starcoin.git Run scripts/dev_setup.sh: cd starcoin ./scripts/dev_setup.sh Then we are ready to compile: cargo build Wait? You haven’t install Rust yet? Please refer to Getting started. ...
