gengen

gengen is a filecoin tool that builds the genesis.car, which is used to seed the genesis block.

Example

go-filecon $ ./tools/gengen/gengen --keypath fixtures --out-car fixtures/genesis.car --out-json fixtures/gen.json --config fixtures/setup.json

Building

The gengen tool expects that you can already build venus. Please refer to the README in the root of this project for details.

go build -o gengen main.go

    	enables json output and writes it to the given file
  -seed int
    	provides the seed for randomization, defaults to current unix epoch (default 1553189402)
  -test-proofs-mode boolean

Configuration File

The gengen configuration file defines the artifacts produced.

• keys defines the number of keys which will be produced
• preAlloc is an array defining the amount of FIL for each key
• miners is an array defining miners, the owner is the key index, and power is the amount of power the miner will have in the genesis block.

Example

{
  "keys": 5,
  "preAlloc": [
    "1000000000000",
    "1000000000000",
    "1000000000000",
    "1000000000000",
    "1000000000000"
  ],
  "miners": [{
    "owner": 0,
    "power": 1
  }]
