🤝Joining Network Using State Sync

State sync offers the quickest way to join SEDA network.

The state sync feature allows a new peer to join the network by asking for a snapshot from existing peers. SEDA provides the following RPC nodes to support this feature. Use these addresses in Step 3:

Network	RPC1	RPC2
seda-1 (mainnet)	18.133.187.48:26657	https://rpc.seda.xyz
seda-1-testnet (testnet)	52.56.225.178:26657	https://rpc.testnet.seda.xyz

Steps:

1. Check the version history and download the correct binary version from the SEDA Chain repository.

2. Initialize your node for mainnet or testnet:

   sedad join <moniker> --network mainnet

3. Query an RPC node to obtain a trusted block height and hash. For example:

   curl -s https://rpc.seda.xyz/block | jq -r '.result.block.header.height + "\n" + .result.block_id.hash'
   
   653231
   B77528F6A290FCFBF25F730C6D490DE0DA7587EC6B2612AA2547773499CFB47E

4. Enable state sync and fill out the relevant fields in config.toml accordingly:

   [statesync]
   enable = true
   rpc_servers = "https://rpc.seda.xyz,18.133.187.48:26657"
   
   trust_height = 653231
   trust_hash = "B77528F6A290FCFBF25F730C6D490DE0DA7587EC6B2612AA2547773499CFB47E"
   trust_period = "168h0m0s"

5. (Optional) Sometimes a recent snapshot may not be available in the peer-to-peer network, making it difficult to verify its header. SEDA runs a node that broadcasts snapshots taken every 100 blocks to the network. To ensure that a request for snapshots is sent to this node, add the following address to the persistent_peers field in config.toml. For mainnet:

   persistent_peers = "[email protected]:26656"

   For testnet:

   persistent_peers = "[email protected]:26656"

6. You may have to disable SEDA signer to start the node. If you are a validator, please read SEDA Keys to set up SEDA signer after you finish the current instructions.

   sedad config set app seda.enable-seda-signer false

7. Start the node.

   sedad start

State sync may be unreliable at times. If it fails, please retry the steps after a few hours or consider Joining Network Using Snapshot.
