# The Portal bridge;s task is to inject content into the different Portal networks.
# The bridge acts as a middle man between a content provider (i.e. full node)
# through its exposed API (REST, JSON-RCP, ...), and a Portal node, through the
# Portal JSON-RPC API.
#
# Beacon Network:
#
# For the beacon network a consensus full node is required on one side,
# making use of the Beacon Node REST-API, and a Portal node on the other side,
# making use of the Portal JSON-RPC API.
#
# Portal Network <-> Portal Client (e.g. fluffy) <--JSON-RPC--> bridge <--REST--> consensus client (e.g. Nimbus-eth2)
#
# The Consensus client must support serving the Beacon LC data.
#
# Bootstraps and updates can be backfilled, however how to do this for multiple
# bootstraps is still unsolved.
#
# Updates, optimistic updates and finality updates are injected as they become
# available.
# Updating these as better updates come available is not yet implemented.
#
# History network:
#
# For the history network a execution client is required on one side, making use
# of the EL JSON-RPC API, and a Portal node on the other side, making use of the
# Portal JSON-RPC API.
#
# Portal Network <-> Portal Client (e.g. fluffy) <--Portal JSON-RPC--> bridge <--EL JSON-RPC--> execution client / web3 provider
#
# Backfilling is not yet implemented. Backfilling will make use of Era1 files.
#
# State network:
#
# To be implemented
