## Summary
|
|
|
|
|
|
|
|
|
|
Current LES is not yet optimized for ultra-light devices like mobile phones. So in the first step introduce
|
|
|
|
|
the ULC addressing this kind of clients.

## Product Overview
|
|
|
|
|
|
|
|
|
|
Current LES is not optimized for usage on mobile phones. So Status is using Infura with all its assets and
|
|
|
|
|
drawbacks. ULC is addressing ultra-light clients and distribution without dependency to central providers.
|
|
|
|
|
Instead a network of trusted LES nodes acts as counterpart for the protocol.
|
|
|
|
|
|
|
|
|
|
So Status is supporting the development and testing of ULC to accelerate integration into `go-ethereum` as
|
|
|
|
|
well as into Status itself.

|
|
|
|
|
|
|
|
Description:
|
|
|
|
|
|
|
|
|
|
- [ ] New Ultra Light Client mode is added to patched LES
|
|
|
|
|
- [ ] Integrate ULC with `status-go` with Status nodes as trusted nodes
|
|
|

|
|
|
|
|
- [ ] Keep battery and network consumption at least as low as today with Infura
|
