This is fun, but it also raises an interesting question , If I make a time capsule for 10 years from now, what guarantees I can still open it if #BCHNostr itself is no longer around?

A time capsule that can outlive the app would be very #Bitcoin . 👀

Welcome to the club😂
Censorship and narrative control, the truth must be kept hidden from the public, the central in a decentralized system 😜

BitcoinCash is the few sane place where decentralization stills hold, whether in Consensus, Forums, or simple conversations

The common assumption: BCH's 0-conf acceptance is a security shortcut — merchants who skip waiting for a block confirmation are just accepting more risk, hoping they don't get defrauded. The implication is that real finality requires a block, and anything faster is wishful thinking dressed up as a feature.

The actual mechanism tells a different story, and the gap between assumption and reality comes down to one architectural decision made in August 2017.

When BCH forked from BTC, it removed Replace-By-Fee. BTC had introduced opt-in RBF in 2016, and kept it. RBF allows a sender to broadcast a replacement version of an unconfirmed transaction — typically one that pays a higher fee to jump the queue, or one that redirects the funds entirely. On a chain with RBF, a merchant who accepts an unconfirmed transaction is accepting that the sender could, in theory, replace it before it confirms. The standard advice for BTC merchants is to wait for at least one block confirmation before treating a payment as final. That's roughly 10 minutes on average, longer during congestion. For a retail transaction, that's not a checkout flow. That's a waiting room.

BCH removed RBF. Full stop. A BCH transaction that hits the mempool cannot be replaced by the sender under the protocol rules. The first broadcast is binding for practical purposes. This is the foundation that makes 0-conf viable — not optimism, not trust in the sender's good intentions, but a protocol rule that eliminates the primary mechanism for transaction replacement.

The second layer of protection is Double Spend Proofs. If a sender attempts to broadcast two conflicting versions of the same transaction — sending the same BCH to two different recipients simultaneously — DSproofs propagate alerts across the BCH network nearly instantly. A merchant's point-of-sale software can receive that alert in real time. The double-spend attempt is visible before any block confirms it. This isn't a guarantee of zero fraud risk in every conceivable scenario, but it makes the attack window extremely narrow and the attempt highly visible.

The practical result: a customer pays at a BCH-accepting merchant using Paytaca or any standard wallet. The transaction hits the mempool. The point-of-sale registers it within 2-5 seconds. The merchant has effective finality. The customer walks out. No waiting room.

This is how 78 businesses in Tacloban City in the Philippines accept $BCH today. Not as a novelty, not as a pilot — as a routine checkout flow. The same architecture is why Argentina has 400+ BCH-accepting businesses nationally, including K24, a convenience store chain that accepts BCH at 30 of its 85 locations. A K24 cashier with a line of customers cannot operate a 10-minute confirmation wait. They can operate a 2-5 second mempool confirmation. The protocol makes that possible.

The fee side of this matters too, because 0-conf only works reliably when the mempool isn't congested. On a chain where blocks are perpetually full and transactions compete in a fee auction to get included, the mempool becomes adversarial — high-fee transactions jump the queue, low-fee transactions linger, and the timing assumptions that make 0-conf safe start to break down. BCH's median transaction fee right now is $0.00081. Average blocks run roughly 60-80 kilobytes out of a possible 32 megabytes. The fee auction that defines BTC's fee environment never starts on BCH because blockspace supply exceeds demand. Transactions get included in the next block reliably. The mempool clears. The timing assumptions hold.

ABLA — the Adaptive Blocksize Limit Algorithm, activated May 2024 — sets 32MB as a floor and adjusts the ceiling upward automatically based on observed demand. If BCH transaction volume scaled dramatically, blockspace supply would respond before congestion could develop. The 0-conf security properties are designed to remain intact as the network grows, not to degrade under load.

The gap between the common assumption and the actual mechanism comes from conflating BTC's architecture with BCH's. On BTC, skipping confirmation genuinely does mean accepting more risk — because RBF exists, because blocks are full, because the mempool is congested. That analysis is accurate for BTC. It doesn't transfer to BCH because BCH made different protocol choices. Removing RBF wasn't a minor tweak. It was a foundational decision about what kind of payment system BCH would be.

The original Bitcoin whitepaper described a peer-to-peer electronic cash system. Cash settles at the point of exchange — you hand over the bill, the transaction is done. 0-conf on BCH is the closest any major proof-of-work chain has come to that property in practice. The protocol enforces it. The math supports it. The 78 merchants in Tacloban are evidence it works.

[Nurain🥑 @Nurain_Dev]

Most people in crypto don’t actually want peer-to-peer electronic cash.

They want a number on a chart.

Bitcoin Cash stayed focused on the boring part:

Make Bitcoin useful as money.

And that might be the most controversial idea in crypto. ⚡️

Of course not. Anything But BCH!!!

[BiorLabs @BiorLabs]

Bitcoin Cash people have been saying the same thing for about a decade now. Money should move like cash. A wire transfer that needs three business days to clear is not really money moving at all. Hard to argue.

[夏小栀 @bch_sun]

Nearly a decade has passed, and reality has given us more and more counterexamples. Hardware, bandwidth, and storage have continued to improve, while other blockchains have repeatedly shown that L1 has far more room to scale than we were once told. The question is no longer whether L1 can scale, but how far it can reasonably scale. Even Vitalik, looking back on the blocksize war years later, acknowledged the shortcomings of the L2-centric approach in practice.

Meanwhile, Lightning never became the simple, natural, global payment network for everyone that many had hoped it would be. To work around what was originally a fairly simple problem, we ended up with channels, liquidity management, routing, online requirements, and an increasingly complicated user experience.

So when people look back today, more of them are starting to ask:

Maybe we weren't rejecting a bad way to scale Bitcoin. Maybe we gave up too early on Bitcoin's most direct path to scaling, then spent nearly a decade trying to solve with increasingly complex engineering what might have been solved much more simply.

That may also explain why people who once wouldn't even read Roger Ver who would stop listening the moment they heard his name are now willing to open his book and reconsider what he had to say.

History hasn't changed.

What has changed is that we now have nearly a decade of real-world results against which we can judge the promises that were made.

[夏小栀 @bch_sun]

This is where “wallet” starts to mean something more than just a place to hold and spend #BCH .

With CashTokens support, BiorVault can also become a home for assets and applications built directly on Bitcoin Cash community tokens, loyalty points, NFTs, and other on-chain projects.

BCH isn't just money you can move. It's infrastructure you can build on.

[夏小栀 @bch_sun]

Sidechains make sense for things that genuinely don't belong on L1. But scaling shouldn't start with the assumption that L1 must remain artificially constrained.

If the main chain can do something cheaply, securely and at scale, just let it do it. Sidechains should expand what's possible, not recreate capacity we deliberately removed from L1.

[smartBCH @SmartBCH]

@0zkBrewer This is getting interesting. Stealth transfers for receiver privacy, confidential spends for transaction privacy, and PQ security underneath is that roughly the direction you're heading?

[0zkBrewer @0zkBrewer]

Making good progress on stealth transfers on #BCH.

An old project I built for someone on #SOL features this exact capability to send funds privately directly on-chain.

[BCH 王二分 @wangxuelong007]

People often ask, "How do I know that BCH is not a scam?"

Good question. Teach you a 3-second judgment method:

Characteristics of the scam:

❌ There are founders standing on the platform, shouting orders, and promising profits.

❌ There are "pulling people's heads to return profits" and "locked position dividends"

❌ The code is not public, and the white paper is PPT

❌ All your searches are advertisements of "rich" and "wealth freedom"

Characteristics of BCH:

✅ No CEO, no company, no customer service

✅ The code is completely open source, and anyone can audit it.

✅ The white paper is Satoshi Nakamoto's 2008 paper.

✅ You search for BCH, and what you see most is "how to use" and "how to buy", not "get rich"

The scam is desperately trying to make you buy it. BCH only said "self-study".

If you ask this question today, it shows that you are more sober than 90% of people.

Keep this habit. 🧠
