Developer for TumbleBit.
TumbleBit is a Boston University research and open source project that is building software to improve the privacy and fungibility of Bitcoin. We have a proof of concept implementation which works on Bitcoin's blockchain (on Github).
TumbleBit helps Bitcoin scale by allowing users to send fast out-of-band payments that neither take up space on the Bitcoin blockchain nor suffer from the long wait times (~10mins) required to confirm Bitcoin transactions. TumbleBit payments are sent via an untrusted intermediary, called the Tumbler. Every payment made via TumbleBit is backed by bitcoins, and comes with a guarantee that Tumbler can neither violate anonymity, nor steal bitcoins, nor "print money" by issuing payments to itself. TumbleBit is fully compatible with today's Bitcoin protocol, and provides a privacy property called unlinkability---noone, not even the Tumbler, can determine which payer paid which payee in a given run of the TumbleBit protocol. Our project roadmap is here.
We are looking to hire a full time software engineer to help make our implementation secure and production ready.
This would be a 6-12 month position, all code written would be open source and available on github.com. Email your CV/Resume to Ethan.R.Heilman@gmail.com if interested.
