1. Introduction

Introduce BCH as a major Bitcoin hard fork—born in 2017 to tackle Bitcoin’s scaling issues with bigger blocks, cheaper fees, and faster transactions—invoking Satoshi’s original vision. (investopedia.com, en.wikipedia.org, binance.com, messari.io, en.wikipedia.org, reddit.com, investopedia.com, reddit.com, bitcoincashstandards.org)

2. The Origins of Bitcoin Cash

Trace BCH’s roots to July–August 2017, when EOS, blockstream debate prompted miners and developers to split and launch BCH in Aug 2017. Every BTC holder received an equal amount of BCH. (coindesk.com)

3. The 2017 Fork: Philosophy and Technical Dispute

Detail ideological rift: Some favored SegWit and layer-2 scaling; BCH proponents wanted on-chain scaling, citing Satoshi whitepaper’s peer-to-peer goal. (coinbureau.com)

4. Block Size Debate: Big Blocks vs. SegWit

BCH launched with 8 MB blocks, increasing to 32 MB in 2018—contrasting Bitcoin’s 1 MB + SegWit weight limit. Explain impact on capacity, fees, and decentralization. (coinmarketcap.com)

5. How Bitcoin Cash Works: Technical Foundations

BCH shares SHA‑256 PoW, UTXO model, 21 million supply, ~10-minute block time, halving cycles.

6. Consensus and Mining in BCH

PoW consensus, 2017’s emergency DAA, replaced with ASERT in 2023. Mining pools dominate—risks for network centralization. (binance.com)

7. UTXO Model and Schnorr Signatures

BCH inherits UTXO, added Schnorr signatures (2019) for multi-sig efficiency, privacy, scalability. (binance.com)

8. Difficulty Adjustment Algorithms

Explain initial Bitcoin DAA, BCH’s EDA fallback, subsequent fix and ASERT algorithm ensuring stable block times. (binance.com)

9. Smart Contracts & Token Standards

Discuss CashScript for contract scripting, Simple Ledger Protocol (SLP) for tokens, Memo protocol for messaging, CashID for authentication. (binance.com)

10. Key Upgrades and Protocol Development

Walk through major updates: 2019 Schnorr, 2020 opcodes, 2023 CashTokens, 2024 adaptive blocksize. (messari.io)

11. The 2018 Split: Birth of Bitcoin SV

Cover November 2018 BCH split, creation of BSV, Craig Wright’s larger-block vision versus Roger Ver–backed BCH continuity. (investopedia.com)

12. Leadership: Roger Ver and BCH Evangelism

Highlight Roger Ver—“Bitcoin Jesus”—championing BCH; discuss his vision, controversies, 2024 indictment. (en.wikipedia.org)

13. Ecosystem & Tooling: Nodes and Software Clients

Detail node implementations: BCHN, Bitcoin Unlimited, Verde, BCHD. Development tools like BCH Unlimited and Bitcoin Cash Node. (en.wikipedia.org)

14. Adoption: Merchants, Payments & Use Cases

Discuss low fees (~$0.001), fast times, merchant adoption for coffee shops and remittances—include user testimonies.

15. Market Dynamics: Price History and Competition

Chart BCH events: launch price ~$294, ATH ~$3.5k (Dec '17), slump, 2021 rally to ~$1.6k, 2024 halving. Compare to BTC and altcoins. (crypto.com)

16. BCH vs. BTC: Comparative Analysis

Side-by-side: block size, TPS, fees, decentralization, hash rate. Acknowledge BCH’s lower security/higher risk.

17. Risks and Criticisms: Centralization and Liquidity

List concerns: small ecosystem, centralized mining/governance, whale control, low liquidity. (fool.com)

18. BCH in DeFi and CashTokens

Discuss SLP and CashTokens, early DeFi efforts, low adoption; challenges from Reddit. (bitcoincashstandards.org)

19. CashScript, CashID & On‑Chain Messaging

Explore scripting, authentication methods, memo attachments—emerging ecosystem.

20. Community Governance and Culture

Swarm methodology manifesto; decentralized dev culture; voice of Pirate Party’s Falkvinge. (wired.com)

21. Regulatory Stance and Legal Positioning

BCH treated as currency; less scrutiny than DeFi tokens. Ongoing regulatory clarity ahead. Mention Roger Ver’s legal case. (en.wikipedia.org)

22. Security Considerations

Explain PoW reliance, hash rate vulnerability, smaller network and 51% risk, comparing hash weight to BTC.

23. Future Roadmap and Proposed Innovations

Outline future upgrades: adaptive blocksize, deeper smart contract support, protocol refinements. (messari.io)

24. BCH’s Role in the Broader Crypto Landscape

Position BCH within forks, contrasts with Ethereum/Layer‑1s, relevance amid DeFi and Web3 trends.

25. Conclusion

Summarize BCH as a bold bet on on-chain scaling and peer-to-peer electronic cash—highlighting tradeoffs of speed vs. decentralization, and its place as Satoshi’s “other child.”
