Dev mode¶
Starting geth in dev mode does the following:
1. Initializes the data directory with a testing genesis block
2. Sets max peers to 0
3. Turns off discovery by other nodes
4. Sets the gas price to 0
5. Uses the Clique PoA consensus engine with which allows blocks to be mined as-needed
without excessive CPU and memory consumption
6. Uses on-demand block generation, producing blocks when
there are transactions waiting to be mined
启动:
$ mkdir test-chain-dir
$ geth --dev --datadir test-chain-dir console
注: 需要指定--datadir, 不然数据存储在内存
