Bitcoin is a complex adaptive system composed of three technologies: transparent trust code blockchain technology, decentralized distributed account UTXO technology, and asymmetric P/NP aware reality adaptive POW technology. There are already plans to vertically expand Bitcoin. One: Expanding POW includes mining pool technology and merging mining technology Secondly, there are (BRC20, recorded in the storage of the blockchain) options for expanding the blockchain Thirdly, there are (Runes) extensions to UTXO The technology of vertically expanding POW mining pool mining machine business has eaten up the majority of profits in the cryptocurrency industry. The biggest charm of Bitcoin lies in decentralization, and the charm of decentralization lies in the distributed UTXO like account model. So, by reusing Bitcoin's UTXO account, we can also obtain consensus from the largest group of Bitcoin users. BRC20/Runes is just the first small step in the technological expansion of the Bitcoin industry, and this small step is similar to the ETH ICO market in 2017, only addressing the speculation that the system can issue coins, without reaching the stage of implementation. The essence of UTXO is not a token, but a distributed account. So we separated the UTXO account system of Bitcoin and reused it. Instead of using Bitcoin's blockchain and POW technology, or using it sparingly. So our expanded business can be infinitely enriched. The guiding logic for this direction is that the greatest value of Bitcoin lies in each holder behind the UTXO account. The Lightning Network is only a demo of BTC transfer on the UTXO account model, and only requires Bitcoin blockchain to operate when initiating arbitration or notarization. And the Lightning Network is also limited to expanding the Bitcoin UTXO account system for currency BTC payment applications. Based on the Bitcoin UTXO account system, we can expand any landing application in this trusted world. For specific instructions, you can refer to the method of learning GEB's P/NP perception of reality to create complex adaptive systems.
