On the occasion of the inscription FOMO tide, I had contact with some “real” Bitcoin developers and found that they would not get hot, saying that some Bitcoin Layer2 subverted Ethereum and the like.
On the contrary, everyone has a consensus: the Bitcoin ecosystem will have a chance, but it will definitely distinguish between the DEFI Ledo Gao combination paradigm of Ethereum.Next, how can the Bitcoin ecosystem be implemented based on technical logic discussion?
Indeed, the new asset issuance method of inscription has pulled many people back to the ICO time in 2017, and the enthusiasm was completely ignited.This wave of inscriptions brings new users, new application scenarios, and newly increasing funds. To some extent, this round of bull market is not an exaggeration.
As a result, side chain, lightning network, Taproot Assets, RGB, BITVM and other directions are full of Bitcoin orthodox Layer2 “saliva”. They often talk about Bitcoin ecosystem high -profile that it is necessaryCrimson orgasm.
Just as the ICO assets issue heat, the inscription market is also eager to undertake a new Bitcoin Layer2 boom when the FOMO tide is over.
There are such ambitions and demands, but if you want to restore the ecological diversity of Ethereum to Bitcoin, it really does not work.Line route.
The core logic is that the Bitcoin chain’s original characteristics have “limited” calculation and verification capabilities. Even if the storage capacity in the Taproot address Segwit also has dust attack “controversy”.
The restrictions determine that more complex trading logic must be realized outside the chain. For example, Bitvm boldly imagined a picture of using the external circuit+the logic door (0, 1) on the chain.After the calculation of the spirit, the brain hole is large, and the technical logic is reasonable, but the amount of engineering is comparable to the people in the Qin Dynasty in the three bodies, which is unrealistic;
The restricted verification makes Bitcoin more suitable for asset settlement, rather than the entire status check of the situation. For example, the Schnorr signature and MAST data structure characteristics of Bitcoin nodes have brought some verification capabilities, but Schnorr only aggregates multiple signatures.Limited to multiple scenes, and MAST allows the creation of more complicated scripts, but it relies on the UTXO model to only make asset settlement and cannot achieve a global state verification.To build a complex light node matrix, it can only strengthen the interactive operation between the side chain and the main chain, and improve the safety and response speed of asset settlement;
Storage disputes are beyond doubt that the development of Bitcoin has now been a minimalist route. This is the consensus that runs out of the last round of block war. Therefore, the idea of trying to make articles based on Taproot’s script space is definitely unreasonable.Although it does not necessarily go to the degree of bifurcation of Segwit, upgrade protocols such as Atomicals, Rune, PIPE, etc. are all compromised in the direction of the block.
These limitations determine that the Layer2 expansion scheme of Bitcoin is very different from Ethereum:
1) Bitcoin Data Availability data can be lacking in performance. Ethereum DA is the calculation of data submitted by the main network Validators on Layer2.Efficient calculation and verification capabilities.
Therefore, the Bitcoin DA is more like the “announcement board” nature. The original RAW DATA is stored in the Bitcoin block, and the INDEXER indexer under the chain can only be used to account for bookkeeping and confirmation.This is bound to test the bookkexer’s bookkeeping and verification capabilities. If multiple Indexer challenges will further increase, there will be a problem of confusion in the book logic.
2) Bitcoin InteroperaBlity is limited to operating performance. Ethereum Layer’s second -layer submission status to the main network. The main network has a contract with the second floor to expand a 7 -day challenge time window, and Layer2 escape compartment to ensure that ensure thatUnder the premise of the second layer of Sequner, the main network can protect the assets of the second -layer users.Obviously, Bitcoin, which does not have the ability of smart contracts, does not exist in this layer of security.Users can only believe that Bitcoin Layer2 will not be evil.
3) Bitcoin UTXO security model is limited by the “payment” scene.Similar to the second floor of the Ethereum Plasma, if the second layer of the Nonce Hash corresponding to each transaction is synchronized in the form of UTXO and the main network, you can find an absolute security mode based on UTXO.
But just as Plasma can only be limited by payment scenarios, the Bitcoin Layer2 based on UTXO models also exists in this limit.Dan Fan is a mechanism with complex smart contracts such as EVM, and it cannot be simply relying on this security mechanism, unless it is superimposed with other Bitcoin chains.
Based on this technical logic and cognition, the narrative space of Bitcoin Layer2 is also extremely clear:
1) Take Bitcoin as a settlement layer, set up independent consensus on the second floor, and provide a whole set of Ecological carrying capabilities that are connected to Ethereum in various types of DA, Interoperability, VM virtual machines.However, such a powerful chain of comprehensive strength is tantamount to building an Ethereum execution chain. Many people actually do not know. In fact, Ethereum also has a Beacon setting chain.Layer2 of the chain.
The reason why everyone perceives the settlement chain is the core of the main network is the ability of the interactive verification. If it is just a settlement chain, the chain of the processing and verification operation of a large number of computing and verification operations will become the real “main chain”.
The question comes. We make the bitcoin as a settlement chain. Do other chains dare to call ourselves the main chain?Does the Bitcoin ecosystem allow such “consensus” to exist?
2) Use Bitcoin to pay SOLUTION, including Lighting Network Lightning Network, Taproot Assets assets, and client verification RGB. It is essentially providing security guarantee based on the Bitcoin mainxo model.The scene is payment.
The Lightning Network’s circulation experience is very silky. Taproot Assets and RGB are actually similar, which is relatively suitable for the payment channel for landing stablecoins.
If you want to superimize some of the status and client verification more status, it is equivalent to adding more complicated verification logic to the original UTXO model.The net is essentially dependent on the chain consensus.Such schemes may be through, but compared to the transaction scenario controlled by pure UTXO model, the security level will also decline.
above.How does the Bitcoin ecosystem land?
If the Bitcoin ecosystem under the security consensus of pure Bitcoin, point to the subsequent stable coin application consumption scenarios such as Lightning Network and Taproot Assets;
If the Bitcoin’s main network consensus is allowed to add some off -chain consensus, it points to the RGB client to verify that this type can realize complex application scenarios that can realize complex Layer2 smart contracts;
If the Bitcoin’s main network only makes a settlement chain and rely on the independent consensus by the chain, it seems that all kinds of side chains, alliance chains, index chains, etc. can be consensus and strictly implement the transparent settlement of assets.
If Bitvm’s Bitcoin Turing calculation verification scheme is really implemented, if it does not change the consensus of the Bitcoin main network, and the cost is lower than the Ethereum smart contract structure, the above conclusion is overturned.
In short, the problem of security+decentralization+scalability is impossible to perform stronger on the main Internet of Bitcoin.The so -called Bitcoin Orthodox Layer2 may be a pseudo -proposition. In my opinion, when choosing an orthodox consensus, you must accept the expansion of the “limit”. If you want to break through the limit, don’t take the banner of the universe invincible consensus.
