State sync

In order to use this feature, you will have to edit a couple of things inside your ~/.realio-network/config/config.toml file, under the statesync section:

1. Enable state sync by setting enable=true

2. Set the RPC addresses from where to get the snapshots using the rpc_servers field:

   • See Peer & Seeds information in order to get RPC addresses in our discord group

3. Get a trusted chain height, and the associated block hash. To do this, you will have to:

   • Get the current chain height by running:

     curl -s <rpc-endpoint>/commit | jq "{height: .result.signed_header.header.height}"

   • Once you have the current chain height, get a height that is a little lower (200 blocks) than the current one.
     To do this you can execute:

     curl -s <rpc-endpoint>/commit?height=<your-height> | jq "{height: .result.signed_header.header.height, hash: .result.signed_header.commit.block_id.hash}"
     
     # Example
     # curl -s <rpc-endpoint>/commit?height=100000 | jq "{height: .result.signed_header.header.height, hash: .result.signed_header.commit.block_id.hash}"

   • Now that you have a trusted height and block hash, use those values as the trust_height and trust_hash values. Also, make sure they're the right values for the Realio Network version you're starting to synchronize:

     State sync height range	RealioNetwork version
     19195000+	v1.7.0

   • Here is an EXAMPLE (no not copy!) of what the statesync section of your ~/.realio-network/config/config.toml file should look like in the end (the trust_height and trust_hash should contain your values instead):

       enable = true
     
       rpc_servers = "0.0.0.0:26657"
       trust_height = 100
       trust_hash = "E8ED7A890A64986246EEB02D7D8C4A6D497E3B60C0CAFDDE30F2EE385204C314"
       trust_period = "336h0m0s"

4. Add peers to ~/.realio-network/config/config.toml file:

tip

Our discord group is a great source for getting peer information from the community. After joining the Discord Group, look for the #testnet-seeds-peers channel or the #mainnet-seeds-peers channel and ask the current members for one if needed.

Add these seeds here to the ~/.realio-network/config/config.toml file

seeds = "....." 
peers = "....."
