We need to structure data engraving. Comparing the recent popularity of various Perp DEXs, the Bitcoin ecosystem has been very quiet these past few months. Whether it's BRC20, Runes, or other Bitcoin asset protocols numbering in the dozens, they all have two fatal issues. Unless these two issues are resolved, I think it will be difficult to regain momentum. 1. There is no official unified asset protocol similar to ERC20. 2. It cannot be truly utilized on a large scale. The first issue is currently unsolvable; the open nature of Bitcoin will only lead to more asset protocols. Unless an asset protocol is strongly pushed during the OP_CAT update (which is unlikely), we can skip this issue for now. The second issue is not just a problem for Bitcoin assets, but it is more pronounced on Bitcoin due to the lack of smart contracts and a unified asset protocol. How can we effectively utilize it? Even if we increase OP_CAT, we can only introduce various rough DeFi applications and follow the old path of the ETH ecosystem? Perhaps that is one way. However, Bitcoin itself has many advantages that the EVM model does not have. Leveraging these unique advantages may lead to a better path than the old ETH route. For example, Bitcoin's data and transactions are atomic, which is a huge advantage compared to the EVM's need to store data on other heterogeneous chains or off-chain. Since we can engrave assets and images in Bitcoin transactions, why can't we engrave the data structure of applications in transactions? With a data structure, it becomes possible to build all applications (program = data structure + algorithm). The early Turing machine was just a tape engraved with many data structures, and through reading and writing (algorithms), it could perform all calculations. This atomic engraving of data on tape (block-chain) is a unique advantage of the Bitcoin UTXO model. With structured data, we can essentially build all on-chain applications. This idea is certainly not my original creation; @gavinandresen mentioned something similar back in 2011: "Bitcoin is a platform for innovation. It’s not just about moving money; it’s about creating a decentralized infrastructure that can support all kinds of applications." With applications, the nearly 100 million inscriptions on Bitcoin can naturally integrate with on-chain applications, potentially becoming "useful" assets. For example, why can't RATS become the admission credential for the RATS community? ORDI might become the most popular red envelope asset for Bitcoin applications? Perhaps in the future, reading a paid article on Bitcoin will require spending several SATS? Bitcoin assets are born from data engraving, and their ultimate vitality must come from the upgraded utilization of data. Transitioning from engraving arbitrary content to 'structuring data engraving' may be the key step to activating billions of Bitcoin native assets and making them truly 'useful.'
