1/10 Tangerine upgrade just went live on @citrea_xyz testnet
This upgrade brings full BitVM (@BitlayerLabs) support in clementine - first time bitcoin has been tested for optimistically verifying a fully programmable layer https://t.co/zngpZH57P1

2/10 The headline: Clementine (their Bitcoin bridge) now has complete BitVM support working. First time Bitcoin's being used to optimistically verify a fully programmable layer in practice rather than just theory. Pretty big deal if it works as intended

3/10 They completely rewrote the proving pipeline. ~50% cycle count reduction for batch proofs is no joke - that's the kind of optimization that actually matters in production. Constant-sized light client proofs too, which makes verifying inside bridge circuits way more practical

4/10 Block gas limit bumped from 8M to 10M

7/10 The storage layer rewrite producing smaller state diffs matters a lot for apps with frequent updates. Rollup bridges, oracles, on-chain orderbooks all benefit here

8/10 Reading their whitepaper, the most interesting part is how Clementine handles Bitcoin fork selection. They're using succinct header chain proofs in their light client design

9/10 Capital efficiency improvements are clever - operators processing hundreds of withdrawals with single collateral, with just one disproof stopping all malicious activity

10/10 Tangerine is the most foundational upgrade since citrea's inception - laying groundwork for mainnet. More technical details can be viewed in the whitepaper they dropped last week

So upgrade your node and say Hi to tangerine!

5/10 Added Schnorr signature verification precompiles - native to Bitcoin and used across Taproot wallets. Also p256r1 precompiles for traditional systems. Makes interfacing with both worlds way cleaner

6/10 Implementing EIP-7702 before Ethereum's Pectra upgrade is an interesting strategy. Racing ahead of the chain you're compatible with is a good move
