@MarioNawfal @grok How much is btc worth in Iran in USD?

1/ People often ask: “Why can’t Ethereum just increase its block size like BCH to lower fees and speed up transactions?” Simple: it literally can’t — or the entire network breaks. Here’s why:

Announcing a developer preview of Quantumroot ⚛√: a new kind of vault offering full 256-bit classical, 128-bit quantum security strength, without relying on new cryptography – it uses only the mining-proven SHA256 algorithm. Quantumroot is an ultra-efficient, post-quantum vault for Bitcoin Cash. It's optimized for business and savings use cases: ‣ With cross-input aggregation via introspection, sweep transactions are 15% smaller per additional input than today’s single-signature, "Pay-to-Public-Key Hash" (P2PKH) wallets. ‣ Post-quantum spends cost ~$0.01 per UTXO in on-chain transaction fees for typical two-input, single-signature transactions. ‣ With CashToken-based aggregation, post-quantum sweeps of 400+ unique addresses or 800+ inputs are less than $0.10. 🚀 ‣ While SLH‑DSA‑SHA2‑128s (SPHINCS+) signatures weigh in at 7,856 bytes, CashToken-based delegation and Bitcoin Cash's UTXO model allow Quantumroot to use LM-OTS signatures (RFC 8554) – improving quantum security, while also reducing signature sizes (2,144 bytes) and preventing on-chain privacy leaks. ‣ Quantumroot can support quantum multi-signature (30+ signers), cross-vault signature aggregation (each signature used by multiple, multi-signature vaults), sweep-free vault upgrades and key rotations, threshold and fallback conditions, time-delayed withdrawals, percentage or amount-based pre-authorizations, inheritance and business-continuity configurations, destination-based withdrawal rules, and more. Most importantly, Quantumroot is quantum safe "at rest" from day 1, even if quantum attackers suddenly steal all Taproot-held BTC. On "Q-Day", Quantumroot wallets can smoothly continue operation – or even reduce their post-quantum transaction sizes by retiring pre-quantum signing. Following Bitcoin Cash's 2025 upgrade, all Quantumroot components are possible on BCH mainnet – today. This developer preview combines these components with 10-100× transaction size reductions and code simplifications made possible by several 2026 Cash Improvement Proposals (CHIPs): Loops, Functions, P2S, and Bitwise. I plan to continue verification, complete security audits of specific Quantumroot CashAssembly templates, and provide an open source implementation for wallets to integrate via Libauth, targeting Bitcoin Cash's May 2026 Upgrade. The full explanation, code, and demo can be found on my blog: “Quantumroot: Quantum-Secure Vaults for Bitcoin Cash” Ask me anything!

Today, Bitcoin Cash just activated a major upgrade: CHIP‑2021‑05 (Targeted VM Limits). It doesn’t add new opcodes or shift to an account model—but it does remove legacy bottlenecks that were holding BCH smart contracts back. Here’s what changed.

🔥🔥🔥

BTC Maxis: "We won the block size war!!!" Me: "You had a war against Satoshi?"

Look, I'm not even being arrogant here. BCH has survived every catastrophe and every bit of FUD you can possibly throw at it. We've survived THREE chain splits, endless propaganda, censorship, and astroturfing, an entire exchange and sidechain collapsing, and our biggest whales capitulating. We've never been 51% attacked despite having minority sha256 hashrate. We've stayed solidly in the top 25 by market cap despite a dwindling ratio against BTC. We've shipped substantial beneficial upgrades every year since 2020 and it's safe to say we have some of the best tech in the entire industry. We're one of the only coins actually focused on real peer to peer commerce and economic activity. We've turned our community from a group of people who dwells in the pain of the past into a group that's optimistic and forward-thinking. We have some of the best developers in the entire space, creating some of the best, most user-friendly and practical wallets and apps in the space. Even the volume of trolls and haters are negligible now. We simply stay in our lane, shipping awesome stuff. More and more people are taking notice. The only argument left against BCH is a price/hash chart and a transaction volume graph. Don't worry, we're working on those too. :) There's never been a better time to get into BCH than today. Don't sleep on us. 💚

There is no faction in crypto with more conviction than BCHers. (Maybe Monero bros are close.) Expect us...

By order of the President of the United States, a blockchain is not a blockchain unless it’s open-source.

BREAKING: Vitalik speaks on quantum computing - how will eth handle quantum resistance - how will bitcoin handle it - what happens to satoshi’s 1 million coins. Will satoshi have to move them or will a hacker steal them? MUST WATCH

Proposing three CHIPs for Bitcoin Cash's 2026 upgrade: loops, function eval, and Pay to Script (P2S). These would make BCH contracts more efficient than ETH, SOL, etc. across some remaining gaps + optimize transaction sizes for zero-knowledge and post-quantum covenants. (1/6)

There now exists on #BCH a native (on-chain, miner-verified), provably over-collateralized, dollar-pegged stablecoin. Still in beta but I cannot overstate how awesome and huge this is. Connecting my wallet and minting these 20 MUSD seriously took less than 10 seconds.

Since May 2023, Bitcoin Cash contracts have been able to implement: zk-SNARKs, STARKs, BLS signatures, Lamport signatures & hash-based signature schemes, post-quantum cryptography, verifiable delay functions, bulletproofs, ring signatures, confidential transactions (within covenants), homomorphic encryption, multi-party computation, and any other cryptosystem being implemented on or in any other cryptocurrency. (Note these were also possible on Bitcoin Cash in 2009, but they were broken by the 2010 emergency anti-DoS patches.) Bitcoin Cash's May 2023 upgrade allowed computations to be split across inputs and/or transactions, so even without further upgrades, it is already possible to perform any kind of computation within Bitcoin Cash contracts. In practice though, important use cases require KBs or MBs of transactions to incrementally complete a computation, presenting a practical barrier to development and deployment. After the 2025 BCH upgrade, many constructions that would have ballooned transaction sizes by KBs or MBs will now require only a few bytes: larger stack items and bigint arithmetic bring down these transaction sizes by 10-100x. Technically only a quantitative improvement, but significant enough to feel qualitative. So for the record, BCH has been computationally universal since May 2023, the 2025 upgrade just makes things more efficient: smaller transactions, lower fees, and simplified development/security audits. For comparison, I'll note again that these constructions have also been possible on ETH since it's inception (but with higher fees), and BTC since the Taproot Schnorr hack (but with KBs or MBs of waste in transaction sizes vs BCH).

This is not part of the 2025 Bitcoin Cash upgrade, but over the next few years I expect to see Bitcoin Cash covenants that allow users to deposit BCH and CashTokens and receive "privacy-wrapped" BCH and CashTokens. Within these privacy covenants, users can indefinitely transact

Bitcoin was hijacked. A group of bad actors betrayed Satoshi and corrupted the rise of Bitcoin as a cheap and instant payment tool for the masses to sabotage the rise of crypto as digital money and to install an insecure and custodial second layer to control Bitcoin. Read this:

The May 2025 upgrade to Bitcoin Cash is now active on chipnet at block 227,228! 🎉 (0000000000b8dc4625844fa367b12317645fac7c9afbc5fb8def4025a6822c86) This upgrade includes two Bitcoin Cash Improvement Proposals (CHIPs): Targeted Virtual Machine Limits CHIP The VM Limits CHIP retargets Bitcoin Cash's Denial-of-Service limits to extend compute for real contracts by more than 100x while reducing worst-case node compute usage by 50%. By reducing overhead, the retargeted limits simplify contracts, reduce transaction sizes, streamline contract audits, and improve overall security. By improving contract efficiency, this upgrade also makes important use cases more practical, including post-quantum cryptography, stronger escrow and settlement strategies, zero-knowledge proofs, homomorphic encryption, and other crucial innovations for the future security and competitiveness of Bitcoin Cash. Finally, this upgrade raises the bar by contributing new tooling and a cross-implementation benchmarking methodology to continuously verify node performance. Beyond empirically verifying the safety and correctness of the upgrade, these tools will simplify development of new production-ready implementations, prevent regressions in existing implementations, and reduce the cost of verifying implementation-specific software updates. BigInt CHIP: High-Precision Arithmetic for Bitcoin Cash The BigInt CHIP enables high-precision math for Bitcoin Cash, offering over 10x reductions in contract lengths and making previously-theoretical use cases immediately practical: more advanced automated market making and exchange protocols, decentralized stablecoins, collateralized loan protocols, cross-chain and sidechain bridges, zero-knowledge proofs, post-quantum cryptography, homomorphic encryption, and more. This upgrade takes full advantage of Bitcoin Cash's fundamentally more scalable architecture to offer math capabilities which exceed those of Ethereum: "bare metal" performance, more byte-efficient transactions, far lower transaction fees, and protocol-level simplicity that eliminates whole classes of Ethereum contract vulnerabilities. These capabilities are available to Bitcoin Cash contracts on "layer one" – ensuring security, censorship resistance, and cross-contract compatibility – without increasing compute requirements: fully-archiving Bitcoin Cash nodes can continue to run on inexpensive, consumer hardware.

I’m surprised that $BCH is still a sleeping giant. It’s literally #BTC but exactly what the white paper set out to create.

Oh, you believed them when they told you that BCH was a dead chain? That couldn’t be further from the truth! The eco-system is thriving and growing at break-neck speed! If you want true Bitcoin innovation; Here are 7 new(ish) projects that you’ll love! 💚:
