It was not surprising that when I heard that @Nervosnetwork played BTC Layer2 in the backwater.Because the CKB public chain technology is close to BTC and ahead of BTC, it can not only undertake the native UTXO characteristics, but also achieve higher -level programming feature expansion.If the CKB public chain is not possible to surpass the narrative of BTC, it is second to retreat, and the Layer2 of BTC will definitely be invincible.Why?Next, let’s talk about CKB.
The current BTC Layer2 market is limited by the defects of BTC’s main network in verification capabilities, and there has been a situation of blooming flowers.That’s right, because the BTC main network script language is innate and simple, and its calculation+verification ability is almost 0, it gives the market full of space and opportunities.At present, in addition to the limited transaction inspection+multi -signing of the UTXO unlocking conditions, everything else that needs to be verified data DATA, status change and other complex trading logic cannot be realized directly, but only BTC can only be used by BTCAs an asset settlement layer, an extension of a powerful public chain to build a local consensus and computable verification capabilities to achieve expansion.In this way, the landing standard of BTC Layer2 has no unified standards. There is no “orthodoxity”, and it is even difficult to distinguish between high.You can only distinguish between narrow and broad senses according to the perception of community Community: In the narrow sense, only the one -time sealing Single Seal of the lightning network state channel and RGB is the real BTC orthodox Layer2, because they are fully sufficientApplications have played a limited script verification capacity of BTC, and do not need or rely on the minimum chain local consensus.In a broad sense, as long as the local consensus of the external extension chain is recognized, there is a cross -chain bridge solution that ensures the safety of assets. In theory, the Ethereum EVM chain, Solana high and hair performance chain, etc. can all act as Layer2 of BTC.Obviously, the current BTC Layer2 market is obviously polarized, either extremely narrow, and develops slowly and difficult to develop like Lightning Networks and RGB.It is BTC Layer2.So, there is no “folding” solution?Yes, the answer is: @NervosNetwork, which is adapted and upgraded by the UTXO model and performance of the technical bottom framework.Specific performance:
1) CKB Network and BTC are completely different in the “UTXO model, mining consensus mechanism”, and different account balance models such as Ethereum and other mainstream public chains. UTXO has a certain unique advantage.The parallel processing of anti -double flowers has certain advanced characteristics, which is the greatest invention of Satoshi Nakamoto.This also explains why after Ethereum, SUI and APTOS use similar UTXO models.We can say that Bitcoin’s capacity and block speed have the limitations of the times, but the UTXO model is very advanced.CKB follows the UTXO model and upgrades it to the Cell model. This model not only retains the transaction pureness of the Bitcoin UTXO model, but also provides the data status of account models such as Ethereum.Popular understanding: The Bitcoin UTXO model creates and destroys the process of continuously destroying and casting by coins, and Cell removes the destruction process. It wants to verify and keep the state for a long time.Each Cell contains two fields of CapaCity and Data. Capacity uses bytes as the balance of UTXO; data is preserved so any form of data such as historical transaction status;, It can also include a series of smart contract complex state.In general, Cell model is a leading trading model with stronger continuity, better flexibility, and at the same time that can enlarge the scope of the UTXO model.It is also the key to CKB that can inherit the security of the BTC main network and can “speed up” the slow expansion direction of Bitcoin such as Lightning Network and RGB.
2) Take the recent CKB launched RGB ++ as an example. According to the normal process, the BTC ecosystem will extend the mature RGB solution. The difficulty is not the one -time seal of the BTC main network, but it is precisely the communication between the client verification node under the link.The process of coordination and status co -maintenance, especially in the case of node decentralization and decentralization.In other words, the RGB theory looks easy, but the practice is limited by the restrictions on the foundation Infra and other restrictions leading to obstacles.
CKB saw this clearly, and simply allowed all these nodes to verify these under -chain clients to participate in the public verification process of the CKB chain.This directly speeds up the UTXO extension client’s practice path that RGB wants to implement.After all, the complex P2P node network consensus under the chain client environment is difficult to achieve, full of complexity and challenge, such as: under -chain communication may face data synchronization delay or inconsistent issues, there are some fraud and attack challenges.If this process can be moved to the environment on the chain, it is simple.3) RGB ++ has recently been discussed more recently. I will add a data format of an Open Transaction data proposed by CKB, and everyone can feel the advanced characteristics of the CKB chain.Simply put: Open Transaction allows multi -party participants to build and aggregate different transactions within different times, including three major characteristics: partial construction, allowable modification, incremental construction, and aggregation.For example: Alice created an Open Transaction that stated that he wanted to exchange from BOB how many tokens A was exchanged for token B. After the transaction was initiatedYou can add your own tokens B and supplement the trading conditions.At first glance, I feel very abstract. For example, in the cross -chain scene, Alice and BOB can independently complete asset transactions in different heterogeneous chains, which greatly improves the cross -chain interactive operation of the CKB chain; in complex DEFI trading scenarios,The DEFI involved in users may need to be dynamically adjusted according to market changes. Through Open Transaction, contract participants can flexibly adjust trading conditions during the contract execution process, which undoubtedly greatly enriches the complexity processing capacity of transactions.
In my opinion, the unlocking conditions of Open Transaction and UTXO transactions are exactly the same, which can unlock the establishment of complex transactions. The transaction environments such as multi -party signatures and complex application scenarios are also integrated.EssenceaboveInterestingly, as a member of the Ethereum core R & D team @busyForking, the first out of the mountain turned out to use the UTXO model of BTC.Although Ethereum’s smart contract model is now more widely used, Jan and his NERVOS team paranoid the extension and upgrade on the UTXO model of BTC.It not only expresses the awe of Satoshi Nakamoto’s minimalist UTXO trading model, but it has also become a BTC Native Layer2 reason for it.
Summary: I am very optimistic about CKB doing BTC Layer2.In the short term, it can indeed speed up the landing of the Lightning Network and RGB on the UTXO model chain. At least it can provide a meaningful reference for these two types of orthodox expansion schemes on the BTC main network.The characteristics and the characteristics of the underlying architecture and the capacity of the capacity can make it go further in this BTC Layer2 without standard melee.
Note: There are many technical details and highlights of CKB, and more content can be further analyzed again. I can’t help but sigh. BTC Layer2 gave some opportunities for new chains.ah.
