You are likely comfortable handling private key material directly (safeguarding seed phrases), but I suspect most of your friends and family lack the time or interest to properly research and study how to do this. So for them Bitkey is a safer solution than exchanges or self custody wallets with footguns.

Are you familiar with the Emergency Access Kit and how it works? It allows a Bitkey customer to transfer their funds to another wallet in the event Block's server and app are no longer available.

My advice to anyone choosing to self custody bitcoin is to only move a small portion of your stack into a new (to you) configuration or a new product. No need to rush into it. Start early but get comfortable over time before moving larger portions of your stack.

2024-12-23 23:27:52

If you are giving Bitkey as a gift to friends and family members, be sure to have them setup a Trusted Contact to protect them in case they happen to lose both their phone and hardware device.

Bitcoin is very hard to change, a property that is critical to it having any value at all. But, what exactly prevents it from being changed? Bitcoin is also bigger than ever, so how do improvements get made?
Announcing the open source bitcoin consensus analysis project (BCAP).
Earlier this year, @avichal and I discussed the potential for such a project, and over the past few months, I have been working with @0xren_cf and @LynAldenContact to go from concept to a solid starting point, which can now be found at the link below
https://github.com/bitcoin-cap/bcap
Bitcoin consensus is simply a set of rules codified in software. However, what maintains that consensus and what allows that consensus to change is extremely complex. What roles do each of us play in this consensus? What motivations and powers do each of us have?
This project identifies 6 stakeholder groups that play a role in bitcoin consensus including each group's motivation and powers. It also analyzes how each group’s power shifts over the lifecycle of potential change. https://github.com/bitcoin-cap/bcap#stakeholders
Ultimately, investors have the most power, but their power is often exercised late in the lifecycle of change when bitcoin might be on the brink during a contentious fork. Ideally, we avoid winding up in such a fragile state, so the project explores this dynamic.
The Bitcoin Core project is just one implementation of the bitcoin protocol, but it wields tremendous power given it is the software run by a near-majority of the bitcoin network. It has earned this position by prioritizing security and being conservative on protocol changes.
Historically, changes to bitcoin consensus have been proposed by Bitcoin Core developers and have all been merged into the Bitcoin Core project. Recently, there has been a shift to non-Core developers proposing changes. It is unclear whether this impacts Core prioritizing these.
Often people claim that Bitcoin Core has too much power as a few devs can “change bitcoin.” While this is clearly untrue, the opposite is true in that there is veto-like power to prevent changes.
Thus, alternative consensus clients are an important option. However, they are for extreme situations as it would be very difficult to gain widespread adoption. Low adoption can lead to a fragile network.
The project explores one such scenario in which a change is (partially) activated with miner hash rate but low adoption from nodes. This can lead to a sizable bounty forming tempting miners to create a chain split, and leaving bitcoin in a state of chaos. (let’s avoid this)
If a trading market develops between fork A and fork B, investors determine the value, but it turns out not all investors are equal. Self-custody individual investors have advantages over corporate and institutional investor segments.
There are many other future scenarios, and we’d love to see the project evolve to analyze these as it is intended to be a community project that serves bitcoin well into the future. The project is off to a great start with 2 dozen reviewers spanning all 6 stakeholder groups.
If anyone sees ways to improve this project please file an issue https://github.com/bitcoin-cap/bcap/issues, open a PR https://github.com/bitcoin-cap/bcap/pulls, or begin a discussion https://github.com/bitcoin-cap/bcap/discussions.
There is a PDF version in case that is easier to read or to share with others. https://github.com/bitcoin-cap/bcap/blob/main/bcap_v1.0.pdf

5 reasons miners benefit from Stratum v2:
1. Authentication and encryption. Don't let your hash rate be stolen. Even if you aren't concerned about this, your auditors and investors likely will be.
2. Less bandwidth-intensive protocol (binary vs. JSON); reduce stale shares and works better in poor internet situations
3. Ensure your pool isn't inserting transactions and not sharing out-of-band fee payments. It is becoming more topical with the increase in usage of transaction accelerators and non-standard transaction inclusion. Eliminate the requirement to have to monitor your pool.
4. Ensure you're selecting the transactions that provide the maximum fees. Don't leave it to others who may censor certain high fee transactions. Eliminate the requirement to have to monitor your pool.
5. Take charge of the bitcoin software you run and consensus rules. Don't leave it to others to determine whether or not to signal for support of a particular change or to take the risk of falling out of consensus. Eliminate the requirement to have to monitor your pool.

Oh, well I don't think the point that LN has found product market fit as the open payment protocol has been discussed hardly at all, so I wanted to start the conversation. The fact LN is enabling nostr zaps is super cool but not in and of itself a demonstration of it being the open payment protocol. It is the emergence of Fedimint and Cashu e-cash systems that largely demonstrate that LN is becoming that as well as Ark and statechains support for LN as OPP.

2024-05-28 18:24:39

- reply

I sense from your responses that your hope is LN will offer near-zero fees while also being non-custodial with an economically viable unilateral exit. I understand it was sold this way by some folks but it isn't reality. LN's fees are a function of on-chain fees, which are going to be volatile and will continue to increase over time.
There are efforts to try and share UTXOs with more people which would allow for amortizing these costs over more people. This is awesome R&D, and I hope to see more of it. But so far, I've yet to see a design that doesn't result in some other tradeoff, such as a vastly more expensive unilateral exit or some other trust assumption.
I'm also not sure if you're understanding the point I'm trying to make. I'm saying LN has already succeeded at product market fit, but for something other than what you're imagining. I'm not saying it offers no/low fee non-custodial payments, but I am instead saying it is THE open payment protocol, connecting not only non-custodial LN wallets and custodial LN wallets but also wallets that use entirely different designs such as Fedimint, Cashu, Ark, and statechains. All of these different solutions already support LN as the open payment protocol. There's evidence that indicates LN solves that problem. Hence, product-market fit.
As for bitcoin as p2p currency, you're free to move on, but I'm going to continue working toward that as a north star. Each and every year we'll inch closer toward that, but we also shouldn't shy away from practical, useful products and designs that work today and are moving toward that north star.

2024-05-28 13:50:31

- reply

Any user of, for example, Phoenix, Mutiny, Cash App, Coinbase, a Cashu wallet, Fedi, etc. can seamlessly pay each other and not even understand each of those represents very different tradeoffs and have completely different designs. What they have in common is using bitcoin as money and LN as the open payment protocol.
If you don't like paying 0.4% fees for a non-custodial mobile LN wallet, then you have the option of using a custodial or e-cash wallet to avoid the fees along with the associated tradeoffs.
Yes, we'd all love a wallet design that supports 8B people, has no fees, is as censorship-resistant and security as on-chain bitcoin, but that doesn't exist today.

Yes I've used many and support many who are adopting LDK. I think Phoenix is the best UX with reasonable fees but it is no longer available to me. I like Mutiny as well and it is my preferred non-custodial LN wallet, but they've had problems with their LSP scaling. It is all very early.
Even once all the kinks are worked out, there are fundamental challenges with a LN wallet that make it impractical for small amount spending wallets (eg $20 balance) that are used to zap in nostr or on Stacker News.
There are other solutions such as e-cash that don't have that problem, but e-cash systems make other tradeoffs. Thus back to my original point, which is there's no single solution that serves everyone's payment needs. The good news is there are many solutions in the works, and LN is the open payment protocol connecting them all so users of different systems can seamlessly pay each other. It is quite beautiful.

2024-05-27 18:41:22

The secret sauce I refer to is LN as the connective tissue or glue between systems. I'm asserting it is unique in its ability to instantly settle payments between disparate systems.

2024-05-27 18:38:00

- reply

I'm not under a rock, and I'm sorry to break it to you, but no cryptocurrency has solved scaling. There's no silver bullet solutions. There are only tradeoffs. LN is _unique_ in that it interconnects these different solutions.
Contrast this with, say, USDC, in which there's no interoperability between the plethora of platforms that support USDC. If you have USDC on Base, try sending it to a Kraken wallet. If you have USDC on SOL in a Phantom wallet, try sending it to a Metamask user.

For non-custodial LN wallets, liquidity ads and the LSP spec are liquidity management solutions (realized in code such as https://github.com/lightningdevkit/lightning-liquidity and by services such as Voltage and Olympus).
Ark and statechain-based solutions take different approaches.
Yet other solutions such as Fedimint and Cashu, or Cash App and Coinbase, because they're custodial/pooled funds, avoid those challenges altogether.

2024-05-27 15:59:10

There is yet to be a silver bullet scaling solution for cryptocurrency. Instead, what we have for now, and possibly for a long long time, are many solutions each with distinct tradeoffs that will match different user needs.
The secret sauce to making this all work is LN.

Note: I'm re-exploring such dynamics for the first time in 7 years.
Here's the distinction I'm thinking: Investors hold power because they can put their money where their mouth is. They can sell bitcoin if they don't like the direction. They can express intentions for a fork through futures like in 2017 with Bitfinex s2x futures. But investors aren't economic nodes because they aren't receiving bitcoin on a daily basis.
Economic nodes hold power because they're constantly receiving bitcoin and validating the rules. If economic nodes reject blocks mined by miners that is significant. Or, if they don't enforce new soft forked rules for transactions that miners are mining, that creates a precarious situation for anyone locking up funds in such scripts.
Thoughts?

Bitcoin governance is fascinating. There are 4 main actors each with unique powers: miners, developers, investors, and economic nodes. For now, economic nodes are largely exchanges although this will grow in the future as payments take off (merchants, e-cash mints, LN routers).
