I saw @GOATRollup post about this on Twitter a while ago, but the white paper was so long that it took me three or four days to read before I even started writing. I couldn't understand it, so naturally I couldn't write it down, and without writing it down, I couldn't make it understandable to users. But finally, today I understood the original white paper! It's just too long, so you can just read this post instead 🙋 The problem it solves: Traditional BTC Layer's BTC cross-chain security is too serious. Centralized custody or so-called multi-signature are just for show; they don't fundamentally protect users' assets. Before crossing, everyone is using real money in BTC. After cross-chain conversion, XBTC becomes centralized and not recognized by the industry. ➡️Therefore, what GOAT Network does is perfectly solve the above problems through an optimistic challenge mechanism, allowing users to freely and at any time exchange their BTC back from Layer 2. Specifically, this is achieved through three major innovations: Balancing privacy and efficiency: Simply put, it involves moving complex calculations off-chain, with only a tiny "fingerprint" stored on the Bitcoin blockchain. This caused on-chain verification costs to plummet by two orders of magnitude, resolving the long-standing problem of Bitcoin's Layer 2 network being "unaffordable and unusable." 2. Compared to many projects that simply exist in documentation, GOAT Network's latest V3 testnet is the first complete BitVM2 stack to run in a production environment. 3. Supports decentralized sorters, anchoring the system's transaction ordering to the Bitcoin mainnet. This design completely eliminates the possibility of forging transaction history, ensuring that the withdrawal process is both transparent and secure. 🤔 In contrast to many other solutions that are still debating whether Bitcoin should undergo a hard fork for L2 (such as adding new instructions), However, GOAT's ability to directly utilize the existing Taproot tree to create Turing-complete logic, demonstrating a "localized" engineering capability, is precisely what the ecosystem needs most right now. Addressing users' concerns about asset security and allowing them to seamlessly and freely move BTC in and out of the mainnet and Layer 2 could unlock billions or even trillions of dollars worth of BTC in yield and liquidity. Currently, all BTC ecosystem projects should be built on the GOAT Network. By activating dormant BTC in hardware wallets and old BTC OGs through BitVM3, the BTC ecosystem's capital and user base will experience explosive growth. I think it all depends on them.
