In the rest of this thread, I'll describe CashTokens and why I think they're an important tool for expanding financial access and protecting human rights.

- By 2014, BTC was the clear future of money: inflation resistant, pro-freedom, sound money for the world. A decade later, it's a quirky, unreliable, “digital gold”. This book explains how we lost a decade in the growth of peer-to-peer cash, and how we nearly lost the movement

- Excited to share a new proof of concept: Joint-Execution Decentralized Exchange (Jedex) is a non-custodial, censorship-resistant token DEX architecture for Bitcoin Cash (BCH). Jedex demos new techniques made possible by CashTokens, an upgrade proposal for 2023. (1/n)
- Congrats on the 2023 upgrade, Bitcoin Cash! 🎉 Beginning with block #792773 (000000000000000002fc0cdadaef1857bbd2936d37ea94f80ba3db4a5e8353e8), $BCH supports #CashTokens, future-proof multiparty vaults (P2SH32), and several non-breaking technical improvements to TX validation.
- Very excited to begin rolling out full support for Bitcoin Cash. With average transaction fees on the BTC network now running over ~$20 USD, it couldn't come at a better time.BitPay Will Process Payments on Multiple Blockchains, Starting with Bitcoin Cash | The BitPay Blog blog.bitpay.com/multiple-block… #BitcoinCash #Bitcoin #Segwit
- The May 2023 upgrade to Bitcoin Cash (BCH) is now active on the test network! 🎉 Supported at block #121957 (0000000056087dee73fb66178ca70da89dfd0be098b1a63cf6fe93934cd04c78): transactions as small as 65 bytes, P2SH32 for stronger contract security, and CashTokens!
- 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
Bitcoin Cash's November 15th chipnet lock-in is almost here, and the VM Limits & BigInt CHIP upgrades are expected to activate in 2025! 🚀 If you run a node on chipnet, please upgrade today! Over the past 6 weeks, we’ve been requesting final approval from all stakeholders: over - Just published CashTokens.org, a new website about the CashTokens technology, including technical specifications, documentation, and other resources.
- Reminder: the US Dollar began as a "layer 2" network for gold.Replying to @TheDesertLynxI'm still not sure if creating a "real" L2 is possible at all. The only way to have the same risk profile is to have the same validator set. But if it's the same validator set, it'd be just an extension of the existing L1 (i.e. it directly scales L1 rather than creates an L2).
- Just released – CashChannels: Recurring Payments for Bitcoin Cash. They're noncustodial, privacy-preserving, and can be denominated in any currency.
- 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 (withinThis post is unavailable.
- While some computations are still impractical (requiring loop unrolling and/or multi-input computation), I think BCH is within 1-2 years of exceeding ETH in contract efficiency across all remaining classes of computation. VM limits were the messiest problem blocking Bitcoin Cash
This post is unavailable. - 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.
