witness_node Introduce

witness_node is the GXChain-node program that contains blockchain core features such as packing blocks, verification blocks, and state storage.Starting the witness_node program with the help parameter will output all the commands supported by the tool. The following is an example of how to start the common functions.

1. replay blockchain

Rebuild object graph by replaying all blocks

./programs/witness_node/witness_node --replay-blockchain --fast-replay

fast-replay:no sleep while replaying block blocks

2. resync blockchain

Delete all blocks and re-sync with network from scratch

./programs/witness_node/witness_node --resync-blockchain

3. genesis-json

On the GXChain main-net, this file is built in, no need to specify it manually.

#File to read Genesis State from genesis-json
./programs/witness_node/witness_node --genesis-json genesis.json

4. API Server

Endpoint for websocket RPC to listen on

./programs/witness_node/witness_node --rpc-endpoint="0.0.0.0:28090"

5. P2P Server

Endpoint for P2P node to listen on

./programs/witness_node/witness_node --p2p-endpoint="0.0.0.0:9999"

6. Seed Nodes

P2P nodes to connect to on startup (may specify multiple times)

./programs/witness_node/witness_node --seed-nodes='["testnet.gxchain.org:6789"]'

7. Data-dir

Directory containing databases,configuration file, etc.

./programs/witness_node/witness_node --data-dir=testnet_node

8. Close witness_node

  • If the witness_node is not running in the background, execute Ctrl + C once and then wait for the program to save the memory data and then exit automatically.

  • If the witness_node is running in the background, execute kill -s SIGINT $(pgrep witness_node), and wait for the program to save the memory data and then exit automatically. You can't use kill -9, otherwise the next time you start the index, the index will be rebuilt.
