## Overview

[Bounty #3](https://kusama.polkassembly.io/bounty/3) aims to provide a signing solution to bridge the dApps and mobile wallets, which using Beacon Network as a decentralized peer-to-peer network of nodes based on the matrix protocol, with trustless and encrypted message relaying.

The bounty includes the integration with Beacon SDK with Substrate-based Network, and the integration with Wallet in both iOS and Android. Overall the bounty is completed by the Beacon team, Fearless Wallet team, and Nova Wallet by June 2022.

The bounty includes relatively more work which could be split into different stages. In order to cover the financial risk for the development team, we decide to split the distribution of the bounty into 2 parts. The first part is distributed(on [Subscan](https://kusama.subscan.io/account/FC4tZgWUDpg1AK5uoY7Z9bTaUanemyipoG7Tk8W9YXpxvZ6)) in November 2021 and rest of KSM is hold in a multi-sig wallet on KSM: FC4tZgWUDpg1AK5uoY7Z9bTaUanemyipoG7Tk8W9YXpxvZ6. In June 2022, the rest of the bounty is completed, but the remaining KSM in the bounty can't cover the cost because the KSM price drops in 2022.

As the curator of the bounty, hereby I kindly ask the council to approve the request to top up 1543.17 KSM into the bounty according to the calculation.

## Bounty Distribution Recap

The reward of the bounty is paid in two parts due to the size of the work being big which may introduce financial risk to the teams if we only distribute the reward by the completion of the bounty. 

The first part is summarized in: https://github.com/hanwencheng/Substrate-Mobile-Injector/tree/main/Submission and is distributed by the multi-sig account FC4tZgWUDpg1AK5uoY7Z9bTaUanemyipoG7Tk8W9YXpxvZ6 with 394.328 KSM, the rest KSM reserved for part2 is 694.552 KSM.

The discussion is followed on [Polkassembly](https://kusama.polkassembly.io/bounty/3#75f2df36-575c-4a1e-973d-426fc01542b1)
![First Part Comment](https://raw.githubusercontent.com/hanwencheng/Substrate-Mobile-Injector/main/res/firstPart.png)

The multi-sig wallet is currently handled by 4 accounts for transparency, two from me, one from Pascal of the Beacon team, and one from Anton of the Fearless/Nova team.

To be noticed here. Anton was a team member of the Fearless Wallet team and during the development, he switched his role to only the present Nova team due to the reconstruction of the companies. Anton's role in the multi-sig is not changed as he consistently worked for the bounty and provided useful insights for both teams. This is under the agreement of both the Nova and the Fearless Wallet team, and does not introduce any conflict into the reward distribution.

## Refill KSM 

Due to the volatility of KSM(The KSM price is 368 USD when we distribute the first part of the bounty, now 61.351 USD), we need to add more KSM into the bounty in order to cover the cost of the second part of the bounty.

According to the calculation, we still need 1543.17 KSM.

The KSM will first send to the multi-sig account FC4tZgWUDpg1AK5uoY7Z9bTaUanemyipoG7Tk8W9YXpxvZ6, which is also the original beneficiary of bounty #3. and be further distributed to:
* Beacon team (Paper AG): G4bxLcMawBgsCt3Qj1khSyS1MxorfyHbUXrFyjQ6zySbTrs
* Nova Foundation: H3cSNjAW86NfTecufGPhxutea8KrEcZdPa4XgVKfhTMugej
* SORAMITSU(Fearless Wallet): FyLYnuNoMAVkz1VZMMGZFHDPghQQm1916fCon1CqNt2aXbX

### Future Plan

Currently, the adoption of Beacon Protocol in Polkadot Ecosystem is strongly dependent on the decision if dApps want to integrate Beacon SDK. We find a better way to gain adoption is to integrate the Beacon SDK in the Polkadot.js extension as almost every dApp supports Polkadot.js/extension to connect the wallet. It is also beneficial for dApps because they do not need to extra effort to integrate with Beacon.

So there is some extra work to do on Polkadot.js/extension, the plan is detailed in the Github issue [here](https://github.com/polkadot-js/extension/issues/989)

The beacon team will work closely with Polkadot.js/extension team to make this happen, and apply for a new bounty when it is necessary.
