- Core. [P0] LES and/or ULC are operational and used by at least 10% of all users.
|
|
|
|
|
- Research. Integrate and test ULC in a manner “graceful downgrade”: use infura by default and if it fails, start ULC node.

## Product Overview
|
|
|
|
|
We need LES client enabled on mobile device to be really decentralized and to enable all web3 features for dApps.
|
|
|
|
|
|
|
|
|
|
### Requirements & Dependencies
|
2018-08-27 10:28:54 +00:00
|
|
|
ULC integration depends on research swarm #254

|
### Security and Privacy Implications
|
2018-08-27 10:28:54 +00:00
|
|
|
* Free slots for LES servers(can be resolved by les service model, onlyannounce servers, vipnode)
|
|
|
|
|
* Trusted nodes selection(trusted nodes list can be automatically expanded or changed)
|

|
|
|
|
|
|
|
|
### Minimum Viable Product
|
|
|
|
|
* LES can work as the second Ethereum provider in status app.
|
|
|
|
|
* ULC can work as the third Ethereum provider in status app with static trusted nodes.
