This is really cool! I think a lot of people might be willing to donate to a cause, but only if they believe the cause will meet a certain viability threshold of donations.

Anyone can create an All-or-Nothing campaign where funds are only released if the campaign reaches its stated goal. If the goal is not reached, contributors can claim their refunds.

The problemThe problem

Some projects raised partial funding, but not enough to fully deliver. This created a difficult situation for everyone involved. Creators faced pressure to deliver without sufficient resources, while contributors took on risk without clear guarantees.

As a result, creators became hesitant to propose more ambitious ideas, and contributors became more cautious about supporting early-stage or complex projects.

For many use cases, partial funding is simply not enough. In those cases, direct donation models begin to break down.

How Geyser solved the problemHow Geyser solved the problem

Contributors fund campaigns using Lightning or on-chain Bitcoin. Funds are locked for the duration of the campaign and cannot be accessed by the creator while the funding goal is still being reached.

Meanwhile, contributors can get refunded at any time of the campaign up until the point in which the project reaches the goal.

If the campaign reaches its goal before the deadline, the creator explicitly claims the funds.
If the goal is not reached, contributors can claim their refunds.

This behavior is enforced by @rootstock_io smart contracts, which define the rules of each campaign and ensure they are followed.

@Boltzhq bridging enables seamless interaction between Bitcoin payments and the smart contract layer, allowing contributors to participate using familiar Bitcoin tools without needing to interact directly with Rootstock.

This is definitely a hard problem to solve in a noncustodial way. I'm curious to see how it ends up working out for Geyser.

What is RootstockWhat is Rootstock

I don't know much about Rootstock. They seem to operate a number of bridges as well as a "Bitcoin sidechain"

Rootstock is a Bitcoin sidechain, powering Bitcoin DeFi through EVM-compatible smart contracts. Secured by over 80 percent of Bitcoin’s hash power through merge-mining, Rootstock extends Bitcoin’s utility while maintaining its security and decentralization.

I'll admit that I have a somewhat negative association with merge mining. Probably something that bears a little more research. (There are quite a few posts on SN about Rootstock, but they mostly seem to be from a few years ago).
