🧵 Bitcoin Upgrade History — and why it evolves so slowly

1️⃣ 2009: Bitcoin goes live
The genesis block is mined by Satoshi Nakamoto.
Core ideas:
•Decentralization
•Proof of Work
•Immutable ledger

👉 The goal was never speed — it was independence from trust.

⸻

2️⃣ 2010–2014: Survival mode
•Critical bugs fixed (one nearly caused infinite BTC issuance)
•No roadmap, no VC funding, no marketing

👉 At this stage: staying alive = success

⸻

3️⃣ 2015–2017: The scaling wars
•1MB blocks → congestion → high fees
•Community split:
•Bigger blocks
•Or preserve decentralization

⸻

4️⃣ 2017: SegWit
•Activated via soft fork
•Fixed transaction malleability
•Effective block size increase
•Enabled Layer-2 systems

👉 Bitcoin chose slow + conservative
Those who disagreed forked → BCH

⸻

5️⃣ 2018–2020: Lightning Network
•Layer 1 = settlement
•Layer 2 = payments
•Fast, cheap, off-chain

👉 Strategy shift:
Don’t scale L1 like an app

⸻

6️⃣ 2021: Taproot
•Schnorr signatures
•MAST
•Better privacy & scripting

👉 Single-sig, multi-sig, smart conditions
all look the same on-chain

⸻

7️⃣ 2023: Ordinals / Inscriptions
•Images, data, tokens written into sats
•Fees rise, miners earn more
•Highly controversial

👉 Key truth:
If the protocol allows it, it’s not a bug

⸻

8️⃣ Bitcoin’s upgrade philosophy
•Extremely slow
•Extremely conservative
•Mostly soft forks
•No DeFi, no high TPS race

👉 Bitcoin is not an app
👉 It’s a global value settlement consensus

⸻

9️⃣ One-line takeaway

Ethereum evolves like an operating system
Bitcoin evolves like a mathematical theorem

Once proven, you don’t change it often.
