BitSong

Build and synchronize node from state-sync service

Prerequisites

  • Ubuntu 20.04 LTS or newer

  • Go 1.18.x or newer - Installation guide here.

  • JSON processor jq - sudo apt install jq

  • Essential Build Tools - sudo apt install build-essential

Build BitSong Node

git clone https://github.com/bitsongofficial/go-bitsong && cd go-bitsong
git checkout v0.14.0
make install

Initialize BitSong Node

bitsongd init myNode --chain-id bitsong-2b
wget -O ${HOME}/.bitsongd/config/addrbook.json https://files.chaintools.tech/chains/bitsong/addrbook.json
wget -O ${HOME}/.bitsongd/config/genesis.json https://github.com/bitsongofficial/networks/raw/master/bitsong-2b/genesis.json

Configure state-sync

SNAP_RPC="https://rpc.bitsong.chaintools.tech:443"
SNAP_RPC2="https://rpc.bitsong.chaintools.tech:443"

LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \
BLOCK_HEIGHT=$((LATEST_HEIGHT - 2000)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)

echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH

sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \
s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC,$SNAP_RPC2\"| ; \

s|^(seeds[[:space:]]+=[[:space:]]+).*$|\1\"\"|" $HOME/.bitsongd/config/config.toml

Start BitSong Node

bitsongd start

NOTE: It might take 5-10 minutes for node to catch-up with RPC and download state-sync snapshot.

Once snapshot will be identified and accepted you will see following information in node logs:
