## Summary
|
|
|
|
|
|
|
|
|
|
Introduce the LES Service Model where LES clients can subscribe to higher quality services. Different
|
|
|
|
|
payment models will be available, negotiation between client and full node is done via auctions based
|
|
|
|
|
on demands and capacity.
|
|
|
|
|
|
|
|
|
|
This way full node service provide are able to monetize the services they provide. LES will make the
|
|
|
|
|
beginning, Whisper and Swarm may follow.

## Product Overview
|
|
|
|
|
|
|
|
|
|
Today all light clients are treated equal by the full nodes they connect. A future service model will introduce
|
|
|
|
|
the separation between free and payed services. As outlined by Felföldi Zsolt:
|
|
|
|
|
|
|
|
|
|
- LES will be available either as free or paid service,
|
|
|
|
|
- paid service can guarantee availability and short response times,
|
|
|
|
|
- client bandwidth demand fluctuates with time, good service quality requires reserve capacity,
|
|
|
|
|
- for-profit LES servers can still give away their extra capacity for free (with lower priority than paid service),
|
|
|
|
|
- free service is a good indicator of high bandwidth capacity and therefore the capability to provide good service, and
|
|
|
|
|
- paying clients will prefer servers which already gave them free service so free service can act as an advertisement.
|
|
|
|
|
|
|
|
|
|
Once the service model is introduced changes to Status app are needed:
|
|
|
|
|
|
|
|
|
|
- Migration from Infura to ULC
|
|
|
|
|
- Choice between free and paid LES service
|
|
|
|
|
- In case of paid LES service definition of demands for auction
|
|
|
|
|
|
|
|
|
|
### Remark
|
|
|
|
|
|
|
|
|
|
For Status it also could become interesting to become a service provider offering payed full node services not only
|
|
|
|
|
for own clients. This business case should be evaluated in an own swarm.
|
|
|
|
|
|
