FSN Open Source Community (FOSC) 11/25–12/2nd Double Issue

Greetings all! We paused the press last week on our Fusion Open Source Community (FOSC) updates to make room for the exciting news regarding Fusion’s DCRM open-source release, but we’re back this week with a double-issue roundup. In this update:

  1. The FOSC is now up to 632 applications (from 486 two weeks ago).
  2. 3 of the 7 released bounties have been completed.
  3. Development updates from the various FOSC teams.
  4. New community bounty released (week of 11/25th) — can we say “hardware”?
  5. Cooperation with BTCU, a huge network of leading colleges in China focused on blockchain technologies.

As of today, the open source community has awarded a total of 393 applications with a total of 971,698 FSN (time locked for three months). Remember, you must pass our application requirements to earn the reward. The most common reason for reward rejection is because applicants did not complete the last step: Join the github.com/fsn-dev community and set up as a public member. If you have any questions, please ask for admin help in our Telegram (for regions ex-Asia), or WeChat channel (FOSC开源社区).

The reward distribution completed on December 2 is as follows: 77 people for a total of 141,000 FSN (front end time-locked for 3 months). This compares with distribution week of November 25th of 11 people for a total of 22,100 FSN (front end time-locked for 3 months).

Let’s get on to the breakdown.

Participants: @kernel

Update: The tricky custom keyboard has been integrated so we can create the styles as shared in the design screens. Sign-up, Username Recovery, Portfolio, and Send front-end screens first round build completed. Back-end end points for username creation design completed. We also completed 10 user interviews on the wallet design, which will be very helpful for us to refine our terminology and wallet layout.

The multicurrency wallet shared in our 11/19th update has officially adopted the name “SMPC Wallet”. As mentioned in our last article, the wallet utilizes DCRM to create a 2/3 threshold scheme to manage access and security. The team has made great progress and serve as a beacon of what DCRM TSS is capable of.

Safe & Resilient
Due to the use of a 2/3 threshold, the private key shard hosted on the platform will never have full control of the user’s assets without the user also logging in and sharing their key shard.
When combined with 2 factor authentication, an additional “recovery” shard stored by the user ensures that the loss of hot wallet private key shards (e.g, if mobile phone is lost) will not cause asset loss

Ease of use
Biometrics can be paired with the hot wallet key shard on the mobile device, dramatically lowering the barrier of adoption and making this crypto wallet behave like a “mainstream” application.


  1. Initialization: During the initialization process, two private key fragments are generated by the user, and one private key fragment is generated and hosted by the platform.
  2. Daily use: The operation signature of the asset is completed by the hot wallet private key fragment 1 and the escrow platform’s private key fragment 3.
  3. Disaster Recovery: When the hot wallet private key shard is lost or damaged, users can use the offline backup private key shard 2 in tandem with the escrow platform to recover assets. If the hosting platform fails, users can still use the hot wallet private key fragment 1 and offline backup private key fragment 2 to ensure the user’s control of the asset.

Update: UI design has been completed and some functional development has begun. With the private key part of the escrow, transactions are successfully completed.
