Nodes in China

Problem ##

Users in China might experience bandwidth issues or slowness when building and downloading proof paramaters needed to run Lotus. This article provides a few tips to get around the bandwidth issues.

Speed up proof parameter download for first boot ##

Running Lotus requires the download of chain’s proof parameters which are large files which by default are hosted outside of China and very slow to download there. To get around that, users should set the following environment variable when running either of lotus, lotus-miner and lotus-worker:

export IPFS_GATEWAY=https://proof-parameters.s3.cn-south-1.jdcloud-oss.com/ipfs/

export GOPROXY=https://goproxy.cn
