State sync testnet

Testnet only

The following seed nodes are to be used when configuring a full node for the testnet. If you are looking for mainnet seed nodes, please refer to this instead.

In order to use this feature, you will have to edit a couple of things inside your ~/.desmos/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 to seed-4.morpheus.desmos.network:26657,seed-5.morpheus.desmos.network:26657.
   These are two of our fullnodes that are set up to create periodic snapshots every 600 blocks;

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 http://seed-4.morpheus.desmos.network:26657/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 http://seed-4.morpheus.desmos.network:26657/commit?height=<your-height> | jq "{height: .result.signed_header.header.height, hash: .result.signed_header.commit.block_id.hash}"
     
     # Example
     # curl -s http://seed-4.morpheus.desmos.network:26657/commit?height=100000 | jq "{height: .result.signed_header.header.height, hash: .result.signed_header.commit.block_id.hash}"

   1. 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 Desmos version you're starting to synchronize:

      State sync height range	Desmos version
      0 - 1235764	v0.17.0
      1235765 - 1415529	v0.17.4
      1415530 - 2121235	v0.17.6
      2121236 - 2226899	v1.0.4
      2226900 - 2589024	v2.0.0
      2589025 - 2643234	v2.1.0
      2643235 - 2756259	v2.2.0
      2756260 - 3130831	v2.3.0
      2756260 - 3130831	v2.3.0
      3130831 - 5842610	v2.3.1
      5842610 - 6233130	v3.2.0
      6233130 - 6339185	v4.0.1
      > 6339185	v4.1.0

Here is an example of what the statesync section of your ~/.desmos/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 = "seed-4.morpheus.desmos.network:26657,seed-5.morpheus.desmos.network:26657"
trust_height = 16962
trust_hash = "E8ED7A890A64986246EEB02D7D8C4A6D497E3B60C0CAFDDE30F2EE385204C314"
trust_period = "336h0m0s"
