Lotus Devnet

Runs a Lotus Devnet using a mocked sectorbuilder which can be accesed as a real Lotus node through the API. The devnet code is always tried to be update with Lotus latest master tag.

Compile & Run

make clean
CGO_CFLAGS="-D__BLST_PORTABLE__" make
go build -o lotus-devnet main.go
./lotus-devnet

The devnet supports the following configuration:

• -speed: Time in milliseconds that blocks are mined. Default is 100ms.
• -numminers: Number of miners. Default is 1. (Note: higher values is an experimental feature)
• -bigsectors: Miners will use 512Gib sector sizes. Default is true, if set to false miners will use 2Kib sectors
• -ipfsaddr: IPFS multiaddr to allow the client be connected to an IPFS node as a blockstorage.

All flags can be specified by environment variables using the TEXLOTUSDEVNET_ prefix. e.g: TEXLOTUSDEVNET_SPEED=1000

Important: The API will be listening on port 7777 (not in 1234 which is the usual default).

Docker

The Lotus Devnet was originally thought for integration tests in CI pipelines.

Build locally

You can build the Docker image by running docker build ..

Public images

A public Docker image is hosted in DockerHub on every master commit. Refer to textile/lotus-devnet.

For example, running a Lotus Devnet with 1.5s block generation speed:

docker run -e TEXLOTUSDEVNET_SPEED=1500 textile/lotus-devnet
