Coinbase said 0xB10C, the creator of mempool.observer, will work on a software fork visualizer on Bitcoin’s Signet test network, a tool which could be used to monitor updates of the Bitcoin software (and which may prove useful in light of Bitcoin’s Taproot upgrade). They will also continue to publish research and work on Bitcoin code review.
Barbosa, who only just recently lost his funding from mining company Bitmain, will work on a user interface for Bitcoin Core that will allow its users to access advanced functions without having to use the command line – a coding interface that allows you to talk to your computer to make it interact with applications in the form of text lines.
Additionally, the advisory board chose Barbosa because they “value [his] previous work on code reviewing, and wanted to ensure he could continue in the future,” the release said.
"I'm very fortunate to keep contributing to the project on a regular basis. I hope to be up to the task for one more year," Barbosa told CoinDesk.
Bitcoin developer funding
Barbosa, along with a handful of other Bitcoin developers, recently had funding cut off from Bitcoin mining behemoth Bitmain.
As evidenced by Barbosa hopping from one grant to another, open-source work is fraught with financial uncertainty, and even the best Bitcoin developers may be funded for their work only partially or not at all.
For much of Bitcoin’s history, its developers have worked as volunteers to maintain and improve Bitcoin’s code. Some companies including Blockstream and Chaincode, among others, have funded Bitcoin Core development since before 2017, but it hasn’t been until Bitcoin’s latest time in the limelight that other companies and organizations have upped their efforts to dole out grants.
