YeeCo PoC-5 Node User Guide

2 min readDec 7, 2019

On November 29, the PoC-5 phase of the YeeCo public chain project was successfully completed and officially released, completed the development work of dynamic sharding, CRFG final determination, cross-sharding transactions verification and block reward.

At the same time, for this version upgrade, YeeCo has produced a node maintainer’s operation guide. If you want to run the entire section and use the rpc interface to operate, you can follow the steps below.

Step 1: Click the link below to download YeeCo official Docke mirroring「 yeeco / yeeroot:20191129 」

Step 2: Start the Docker container with the selected shard number

Code show as below:

docker run -d — network=host -v ./data:/data yeeco/yeeroot:20191129 yee — shard-num=0 — bootnodes-routers=http://3.1.169.4:6666

Step 3: Single-shard mining / Multi-shard parallel mining

Single-shard mining

Just deploy the following code:

docker run -d — network=host -v ./data:/data yeeco/yeeroot:20191129 yee — shard-num=0 — bootnodes-routers=http://3.1.169.4:6666 — validator — coinbase=YourCoinBaseAddressHere — mine

Multi-shard parallel mining

1.Deploy four nodes in four shards:

mkdir -p ./data/yee

docker run -d — network=host -v ./data:/data yeeco/yeeroot:20191129 yee — shard-num=0 — rpc_port=9033 — ws_port=9044 — port=30333 — foreign_port=30334 — bath-path=/data/yee/shard_0 — bootnodes-routers=http://3.1.169.4:6666 — validator — coinbase=YourCoinBaseAddressHere

docker run -d — network=host -v ./data:/data yeeco/yeeroot:20191129 yee — shard-num=1 — rpc_port=9133 — ws_port=9144 — port=31333 — foreign_port=31334 — bath-path=/data/yee/shard_1 — bootnodes-routers=http://3.1.169.4:6666 — validator — coinbase=YourCoinBaseAddressHere

docker run -d — network=host -v ./data:/data yeeco/yeeroot:20191129 yee — shard-num=2 — rpc_port=9233 — ws_port=9244 — port=32333 — foreign_port=32334 — bath-path=/data/yee/shard_2 — bootnodes-routers=http://3.1.169.4:6666 — validator — coinbase=YourCoinBaseAddressHere

docker run -d — network=host -v ./data:/data yeeco/yeeroot:20191129 yee — shard-num=3 — rpc_port=9333 — ws_port=9344 — port=33333 — foreign_port=33334 — bath-path=/data/yee/shard_3 — bootnodes-routers=http://3.1.169.4:6666 — validator — coinbase=YourCoinBaseAddressHere

2.Prepare switch profile file path: ./data/yee/conf/switch.toml

File content:

[shards]
[shards.0]
rpc = [“http://127.0.0.1:9033"] [shards.1]
rpc = [“http://127.0.0.1:9133"] [shards.2]
rpc = [“http://127.0.0.1:9233"] [shards.3]
rpc = [“http://127.0.0.1:9333"]

3.Start switch

— bath-path=/data/yee/shard_3 — validator

docker run -d — network=host -v ./data:/data yeeco/yeeroot:20191129 yee switch — bath-path=/data/yee — mine
