 Access to an beacon node that supports the light client specification is necessary. The client must support the following routes from the [consensus API spec](https://github.com/ethereum/beacon-APIs/tree/v2.5.0/apis/beacon/light_client):
 
-- `GET /eth/v1/beacon/light_client/updates`
-- `GET /eth/v1/beacon/light_client/optimistic_update`
-- `GET /eth/v1/beacon/light_client/finality_update`
-- `GET /eth/v1/beacon/light_client/bootstrap/{block_root}`

 System requirements are quite low so its possible to run a light client in the browser as part of a website. There are a few examples of this on github that you can use as reference, our [prover](https://chainsafe.github.io/lodestar/libraries/lightclient-prover/prover) being one of them.
