1/20 Just saw this comment and it hit me - I've been so deep in Bitcoin L2 tech that I forgot most people aren't familiar with the whole ecosystem. @ArchNtwrk is doing something interesting, but it's just one piece of a growing Bitcoin L2 landscape that many haven't explored yet https://t.co/mTeJiWsdfP 2/20 Time for a thread on Bitcoin L2 approaches since a lot of you might find this interesting...

3/20 Bitcoin L2s all try to make Bitcoin more useful without messing with Bitcoin’s core rules. But they take really different technical paths to get there. Let's break them down: 4/20 Zero-knowledge magic (@citrea_xyz, @build_on_bob) These projects use zero-knowledge proofs to prove transactions happened without revealing details. Bitcoin doesn't verify each tx - it checks a single proof that confirms everything is legit

5/20 The math behind this is powerful (@nubit_org, @MerlinLayer2) - like proving you know a password without showing any characters, or proving you have enough money without revealing your balance. That's zero-knowledge tech

6/20 ZK rollups vs. general zero-knowledge tech ZK rollups take this a step further - they bundle a ton of transactions into one proof, making everything cheaper and faster. But zero-knowledge isn’t just about rollups. It’s also used for privacy, security, and even new smart contract logic on Bitcoin 7/20 Simpler to deploy than ZK rollups, but they rely on time delays before transactions are final. Like a bank deposit that shows up instantly but takes days to fully clear

8/20 Bitcoin staking (@babylonlabs_io, @nubit_org) These let you use your Bitcoin to secure PoS networks, acting as economic security without wrapping or moving it. Your BTC stays on Bitcoin but is referenced by another chain. It's like using your Bitcoin's cryptographic proof of ownership to validate actions elsewhere, without the coins ever leaving your wallet.
