We are launching with an initial set of 10 bounty challenges

More bounties might be added as we go

An individual or team who fully solves any of the ten challenges will be eligible to receive a bounty of 2 BTC

For transparency: submissions will be shared with external industry experts to help us discern whether submissions meet bounty requirements

HRF will be making decisions in a charitable way for bounty submissions that make a good faith effort to meet the requirements

We will be leaning to the spirit, not the letter, of the law

Individuals and teams are encouraged to contact bounty at hrf dot org with any questions during the bounty process

HRF retains final approval on allocating prize funds

The Bitcoin Bounty Challenge will run until December 31, 2024

Any unclaimed bounties will convert into general operating funding for the HRF’s Bitcoin Development Fund on January 1, 2025

An individual or team may collect any amount of bounties

If a leading wallet maker or for-profit corporation would like to compete, we would be delighted

To claim a bounty submit proof to bounty at hrf dot org

For full terms and conditions visit hrfbounties.org

This project was born out of 6 months of field research where HRF staff met with + interviewed a) dissidents and human rights NGO leaders from around the world and b) Bitcoin developers

The goal was to settle on a mix of desired upgrades to Bitcoin that seemed somewhat realistic

We fully expect a handful of these bounties to be claimed by the end of next year

We fully expect the bounties to spark debate, arguments, new ideas, criticism, and other stuff that may indirectly help Bitcoin and Bitcoin users

We *do not expect* all of bounties to be claimed

You all have 523 days left

Good luck!

And big thanks to @BitcoinMagazine for covering the news :)
