The Bitcoin Games: Liquid Hackathon
May 30, 2019
|

The Liquid Network is growing fast, and it’s time for you to get involved. As part of our sponsorship of the Bitcoin 2019 Conference, we’ve launched a virtual hackathon for developers anywhere in the world to submit their Liquid applications for a chance to win a first prize of $3,500 in bitcoin, plus many other bonuses.

Time is short: competing teams need to submit their projects by 9th June, so you’ll need to start forming your team now. After registering for the hackathon, Blockstream’s all-star engineers will be making time to help teams make their projects the best that they can be.

Winning projects will be showcased at the Bitcoin 2019 Conference in San Francisco on 25-26 June.

What to Build

The Liquid Network is an inter-exchange settlement network based on a Bitcoin sidechain. By moving bitcoin to Liquid through a process known as a “peg-in,” users can settle Liquid Bitcoin (L-BTC) much faster and more reliably than on the mainchain, as well as take advantage of Liquid’s cutting-edge privacy features.

Liquid also supports the issuance of new digital assets on the same chain (Issued Assets), which are cross-compatible with all other Issued Assets, and can be transacted as quickly and privately as L-BTC. Liquid is based on Bitcoin’s codebase, so developers with experience of working on Bitcoin will feel right at home working with any of the assets on Liquid.

The sky’s the limit for the projects submitted by hackathon teams. While Liquid is primarily built for the Bitcoin exchanges, brokers, and traders, many other users can benefit from its powerful features. We’re hoping the teams surprise us with applications that even we haven’t considered, but to help get your creative juices flowing we’ve listed a few of our own ideas:

Resources

New public Liquid documentation will be launching early next week on the Blockstream site. In the meantime, you might want to take a look at:

Liquid is based on Elements (which itself is based on Bitcoin), an open source platform for building custom sidechains and blockchains. As a result, many of the Elements guides are compatible with Liquid, including:

(To use with a Liquid node, add rpc details to liquid.conf, as you would to connect to a Bitcoin node.)

Any Questions?

We want to get as many people coding on Liquid as possible. If you have any questions, we’d be more than happy to help. Come find one of our many team members in the Bitcoin Games Slack or Liquid Community Telegram group, or feel free to drop us an email. And don’t forget to register for our webinar on Monday!
