Public Rpc Setup

Multiple frontends for Encointer rely on public RPC nodes to query the blockchain state and history. This document describes how to set up a public RPC node for Encointer.

We will assume that you have a full node running already.

The standard config we provide for full node already assumes that you want to expose your rpc service. Please make sure you set --enable-offchain-indexing true. Then, all you need to do is make port 9944 accessible to the public. As the procedure to expose your service varies a lot depending on your setup, we can't provide a one-size-fits-all recipie here.


The following example tests the public rpc and also verifies that offchain indexing is enabled

curl -H "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "encointer_getLocations", "params": [{ "geohash": "0x7530716A39", "digest": "0x77f79df7" }] }'
# {"jsonrpc":"2.0","result":[{"lat":"47.3860442609734562325","lon":"8.5167555883526802063"},{"lat":"47.3863389067466229676","lon":"8.5233766213059425354"},{"lat":"47.3869987892637922755","lon":"8.51989746093749822364"},{"lat":"47.3885922795468204072","lon":"8.51957626640796661377"},{"lat":"47.3891715535333091225","lon":"8.5129961371421813965"},{"lat":"47.3895923857361651699","lon":"8.5164836794137954712"},{"lat":"47.3896700146103739826","lon":"8.52360427379608154297"},{"lat":"47.39043449402448260344","lon":"8.51080611348152160645"},{"lat":"47.3922230783101596785","lon":"8.51907670497894109474"},{"lat":"47.39408059955918872674","lon":"8.5130444169044494629"},{"lat":"47.38784547884539222196","lon":"8.52683097124099731445"}],"id":1}

Announcing Your Public RPC

If you'd like to support the Encointer Network, the world should know about your rpc node. The best way to publish it is through Polkadot js apps. Please submit a PR on their Github repo like this one
