Run and Synchronize your node

This tutorial walks you through the steps to sync the XRP Ledger EVM Sidechain Devnet.

Syncing Options

Syncing from Genesis

Synchronization from genesis involves starting your node from the very first block of the blockchain and processing all transactions to reach the current state. This method ensures your node has the complete history of the blockchain and is fully up-to-date with all network changes and upgrades.

Why Sync from Genesis?

Ensures your node has the complete transaction history.
Verifies all past network upgrades and hard forks.
Essential for participating in the network as a full node or validator.

Chain Upgrades

To keep your node up-to-date, you need to update the binaries whenever a hard fork occurs. Below is a table indicating all the hard forks for each network:

Devnet

Upgrade Name	Block Height	Upgrade Date	Binary Version	Docker image
Genesis	0	Initial Deployment	v1.0.0-beta.0	peersyst/xrp-evm-blockchain:latest
v2	8912879	2024-06-05	v2.0.0	peersyst/exrp:v2.0.0

Steps to Sync from Genesis

Ensure your node is initialized and configured as per the Installation Guide .
Start the node with the initial binary version:
Copy

Copied!
```
exrpd start
```

Monitor the logs for any errors related to hard forks or network upgrades. When an error like the following happens, update the binary to the next version and repeat step 2 as needed until the node is fully synced with the latest version.

Copied!

Syncing from Snapshot

Syncing from a snapshot involves downloading a recent state of the blockchain, allowing your node to catch up quickly without processing the entire history from the genesis block.

Steps to Sync from Snapshot

Download a snapshot from a provider that you trust:

Provider	Type	Current size	Snapshot URL
Peersyst	Pruned	>100GB	https://evm-sidechain-snapshots-devnet.s3.amazonaws.com/exrpd.tar.lz4

Extract the snapshot to the data directory:
Copy

Copied!
```
tar -xzf exrpd.tar.gz -C ~/.exrpd/data
```
Start the node:
Copy

Copied!
```
exrpd start
```
