An intro to bitcoin-focused web development: build your first web app

Careers in bitcoin development are all the rage right now, but it’s an unfortunate misconception that the chance of landing these opportunities are a hundred-to-one unless you’re on a first-name basis with industry pioneers like Nick Szabo or Adam Back. Today’s guest blogger, Kyle Honeycutt, is here to debunk these myths of exclusivity. He’ll also show you step-by-step how to create your very first bitcoin web app, and leaves you with extra resources so you can hone your new skills. Take it away, Kyle.

Earlier this year, we did a featured spotlight on a bitcoin developer Kyle Honeycutt who does tutorials focused on helping explain how to build exciting new tools leveraging the Blockchain suite of services, including our API.

Kyle has impressed us again, by coming up with a novel way to calculate the amount of time left until the bitcoin block reward halving happens in real-time. For those unfamiliar with the bitcoin halving, here is a quick explanation pulled from our 10 commonly used bitcoin terms article.

Bitcoins have a finite supply, which makes them scarce. The total amount that will ever be issued is 21 million. The number of bitcoins generated per block is decreased 50% every four years. This is called “halving.” The final halving will take place in the year 2140.

If you’d like a deeper understanding of the bitcoin halving, you can read Block Reward Halving: A Guide written by Vitalik Buterin, who is the founder of Ethereum. There is also another more recent article which talks about the different aspects of the bitcoin halving which is a good read.

Blockchain API Developer Spotlight: Tim Su


The talent we encounter at hackathons always keeps us energized from one event to the next!

Our most recent hackathon we attended was Hack The Planet, which was designed by Major League Hacking as their finale to end the spring season of hacking. Coming in second place overall and claiming our prize for Best Bitcoin Hack was Tim Su, a developer and student from Northeastern University. Tim created Shuttlepay, an app that unites payment methods like bitcoin, Venmo and PayPal into one neat little app.

This developer spotlight goes into more detail about Tim’s future plans for Shuttlepay and his experience as a developer eager to build bitcoin-friendly software.
