Whichever team brings down the most in the shortest amount of time wins. Monitor extreme and yet unknown network behaviors, discover vulnerabilities, and build a stronger, more resilient bitcoin. This track is for hackers with some level of coding skill, & the ability to use the command line interface (CLI). Familiarity with Bitcoin Core, esp. the JSON-RPC interface is useful. A general understanding of how blockchains and distributed networks work will come in handy. Who's ready to win? Sign up below! 👇 https://mitbitcoin.devpost.com/
