Announcing: Harbor, an ecash desktop wallet for better bitcoin privacy.

https://blog.mutinywallet.com/harbor/

Privacy for the common person is a value worth fighting for. When we see a lack of freedom tools, we must build them into existence. They don't appear on their own.

Much has been said about privacy at the Bitcoin protocol level. For now, we build it on higher layers where we can be more nimble.

Ecash is a tool available today that combines with Bitcoin to bring new levels of common privacy. Cashu and Fedimint are two existing implementations we're interested in.

Harbor Privacy: All communication runs over Tor. Mutiny is not in the middle of any connections or transactions. Funds in the wallet get a Privacy Score to show how the mints provide privacy over time. More to come on this in the future.

Harbor Multi-mint: Instead of relying on a single mint with your funds, spread the risk over dozens or more. Harbor manages this for you, showing you a single balance while connecting with mints for you. A mint can go offline with minimal impact on you.

Harbor Automation: Running as a desktop app unlocks ability to do long running processes in the background. Move money in and out of mints on your preferred schedule to maximize your desired level of privacy. Harbor makes suggestions, but you are in control.

Move money in and out of Harbor using Lightning or on-chain. We love Bitcoin, and we love privacy. We hope Harbor gives everyday people more privacy and peace of mind.

If you don't already know Kenna James, Charity Crawford, Jaye Summers, and Chloe Scott, this film is the perfect opportunity.

Very cool

Amazing, something like this was definitely needed. LFG!

Awesome โšก๏ธ

Wen installable binaries

When it is ready. We mention in the article a few features we still need to develop first. Though you can compile it and play around with it on signet first if you want to try it out and let us know what you think.

Wow, this sounds awesome. So in automation, are funds meant to be automatically moved in and out of different mints and is it that process that in turn increases the privacy score and reduces the link of identity tied to funds?

๐Ÿ’ฏ

This looks fucking ๐Ÿ”ฅ

Excited to see how it turns out! Ecash is a great opportunity to create a layer of fungibility on top of lightning. I for one will be ready to come aboard ๐Ÿง‘โ€๐Ÿš€

how does your privacy score work? purely based on time? does it take the size of the mint into account?

I'd love to see a post on the underlying algo...

It's not fully implemented yet but that's the intention, for both time and mint size/activity.

I'll keep an eye on it. Might even check the code.

Nothing worse than a false promise of privacy for someone who really needs it.

But I don't want to say that you can't do it... ๐Ÿ˜†

You are fucking legends

Love the name, design, feel. Excited to test it out.

Looked neat until I visited the Shithub and saw "Rust" so I know it will likely require 8`437 crates to work and/or be broken every 3 months.

Can I get it on RHEL linux

Mutha fuckaaaa. Yessss! Glad you guys are also keeping nostr:npub126ntw5mnermmj0znhjhgdk8lh2af72sm8qfzq48umdlnhaj9kuns3le9ll in mind. ๐Ÿซก๐Ÿซก

I tried building today on an Ubuntu machine but ran into issues at the unit tests part, think it was database-related.

Are you still just three dudes doing all this?

Mutiny team is truly incredible to pushing ahead.

I appreciate the effort, but even if we assume that mint operators are good people and will not rug pull their users, who in the right mind would take the risk to run a big/reputable mint when they could easily get charged with money laundering and unlicensed money transmission operations?

I like BTC Sessions point of view on this. Operator wont be known and they will build a "kind of trust" over time.

My opinion is to only put your spending amounts on this and to use tools to automatically use multiple mints and reduce the risk.

Also, I wonder if we could have a federated mint with thousands of people. ๐Ÿค”

Unfortunately, scammers will start operating mints without relieving their identities of course and do this so well that they will gain enough trust to hold substantial amounts of btc. Then, they will rug pull. There has to be some kind of collateral that the mint locks on-chain, which gets lost/donated if the mint does not allow users to pull their funds.

If I have services for 5 years and get rug pulled for 50$, it still worth it. ๐Ÿค”

I like your idea with the collateral.

like we need 1000/3000 signatures in the federation. Is it possible?

Great!

Lets say you accumulating ecash in your wallet for a long time and everything worked smoothly. You now have 1M sats in ecash and want to withdraw to on-chain. And as most of it was the ecash you received the new utxo wonโ€™t be made of your own old utxos. Will there be any coinjoining happening under the hood before you get your 1M sats in your Bitcoin address? Will it be a random utxo from a random mint or what exactly will happen there?

nostr:npub1u8lnhlw5usp3t9vmpz60ejpyt649z33hu82wc2hpv6m5xdqmuxhs46turz

It'll be a withdrawal from the mint. It uses one of their mints. No coinjoin needed

When there will be binaries for osx ?

cargo run does work

but the app is just a giant bug at this point

It is still in early development. Any github issues or pull requests would go a long way.

Its using iced super cool

I lost each and every satoshi I put on the mints I played with to test ecash.

I will never see that 5000 sats againโ€ฆ

Finally a good solution for braindead people like me ๐Ÿ‘

๐Ÿค™๐Ÿซ‚

Hell yeah!

Nice ยฅ

This sounds awesome! You guys are doing great work ๐Ÿ‘

Is the this true? No comment here? Or I can't see them? I'm on Amethyst.

Harbor is also FUTO's identity app... ๐Ÿ˜“ https://harbor.social/

How does this compare to Moneroโ€™s anonymity and privacy features? Could Monero be integrated into this?

Is this in production?

Cool
