Our work

An overview of what we are working on and have worked on. We try to be as detailed as possible, but our work is not predictable. This means that sometimes we have to solve a bug quickly or provide support. These actions are not recorded.

We are now working on

The next step for Florin
Time worked: hours
Project: Florin

Total supply and reward update (hard fork). Various bug fixes, network improvements and in-app buy/sell functionality.

Witness Sync
Time worked: 142 hours
Project: Gulden

Fast and efficient synchronization for all applications using our witness system.

Converting Electron for Novo to Gulden
Time worked: 160 hours
Project: Gulden

From this phase everyone can contribute to the development of the Gulden Wallet. Progress and code: https://github.com/Gulden/gulden-official/tree/2.3_development

Electron interface system
Time worked: 1318 hours
Project: Florin / Gulden

The new wallet interface will use Electron. This means that our backend must be able to connect to all functions on the frontend. All those connections need to be built. A new system always brings bugs and they have to be fixed. There is a known bug where windows wallets crash during mining and holding (witnessing). Unfortunately, there is still too little information to fix this bug. This means monitoring and testing, which takes quite a lot of time.

Completely redesigned iOS wallet
Time worked: 1720 hours
Project: Florin / Gulden

The iOS app has been completely rebuilt. The interface is completely new and there are several improvements in terms of ease of use and performance.

Up next

Excluding unexpected bug fixes or urgent functionality requests.
Gulden NFT
Project: Gulden

Unique application of NFT functionality on the Gulden blockchain.

Decentralized exchange

iOS wallet synchronisation issue
Time worked: 43 hours
Project: Gulden

Project: Gulden
Last action: 14.11.20

CORE: Fix a crash in SIGMA verification code that could be triggered in some (relatively rare) instances
RPC: Hide various “hidden” developer RPC commands from the autocomplete
RPC: Introduce a new command “repairwitnessaddress” that can be used to repair a wallet if the witness key for a witness address is not available while wallet is locked (which is required for witnessing)
RPC: Extend “validateaddress” command to give more information for witness addresses
CORE: Minor improvement when renewing witness accounts; check for and repair any instances of missing witness key when doing a renewal

Fee inconsistency with exchange withdrawal
Time worked: 16 hours
Project: Gulden
Last action: 29.10.20

Needs investigation.

Electron for Windows crash during mining/holding (Part II)
Time worked: 96 hours
Project: Florin / Gulden
Last action: 27.10.20

There has been a lot of testing and trying to get information about the wallet crash in the Windows version. Eventually we were able to find out what caused it and solve it. The problem turned out to be for all operating systems, but with Windows this came up faster.

Electron for Windows crash during mining/holding (Part I)
Time worked: 43 hours
Project: Florin
Last action: 23.10.20

Multiple users of the Novo (Electron) wallet for Windows (up to version 1.0.8) experience crashes. Using debugging logs we tried to find out what caused the crash. Unfortunately these logs give too little information. We then ran several tests, but were unable to reproduce the problem. After several days of research we decided to leave this for now and wait until more information is available from users.

Checkpoint system removal hard fork
Time worked: 31 hours
Project: Gulden
Last action: 15.10.20

Gulden used a checkpoint system to increase the security of the network. The implementation of PoW2 makes this system unnecessary. The Gulden Advisory Board decided that the checkpoint system could be removed. This required a change in the software and a hard fork.

New wallet feature for Bittrex
Time worked: 48 hours
Project: Gulden
Last action: 14.10.20

Bittrex required a special functionality in the Gulden Wallet. This was developed and we provided support for its implementation. The Gulden wallet was in maintenance mode at Bittrex during this period. As a result, we prioritized this development and were able to realize it within a few days.

iOS App Store process
Time worked: 21 hours
Project: Florin
Last action: 13.10.20

Because Novo is a new cryptocurrency it required extra steps in the App Store approval process. A few legal matters had to be sorted out on our side. Also small adjustments were needed in the app.

Novo blockchain development
Time worked: 400 hours
Project: Florin
Last action: 10.10.20

Designing, testing and developing the Novo blockchain based on the Gulden blockchain code base.

PoW2 Phase 5 improvements
Time worked: 480 hours
Project: Florin / Gulden
Last action: 27.08.20

With the full implementation of Phase 5, the code had to be cleaned up and stripped of parts aimed at the transition and previous phases. Various optimizations were also implemented.

Delta improvements
Time worked: 240 hours
Project: Florin / Gulden
Last action: 16.07.20

DELTA was changed to using witness timestamps (which are more accurate than PoW timestamps) for difficulty adjustment, as per the original PoW2 whitepaper. Also better accounting for difficulty drop in previous long blocks when calculating difficulty and to soften up some of the rules that were necessary to counteract jump pools. This makes difficulty adjustment smoother.

Last updated: 16.03.21. Time worked is indicative. Only work done by our blockchain developers is included. Excluding user support.
