Recently, BTC Layer2 has sprung up after the rain, and there are hundreds of project arrows on the string, and the entire extended ecology has shown a prosperous and chaotic scene.
Because of this, the new chain cuts into the BTC Layer2 track, and it must find a fit card.Next, the @Mapprotocolall in Bitcoin ecology is known to be passers -by, but its final may not be Layer2, but the interoperability layer of BTC.Why?
Because in my opinion, there is no clear “standard” and “specification” at the current BTC Layer2 ecology: the mature EVM Composition chain is used as BTC Layer2; the independent side chain that can safely cross the chain BTC assets as BTC Layer2; canThe new chain of some UTXO account models is also regarded as BTC Layer2, including BTC Layer2, such as the status channel lightning network and client verification of RGB.
Theoretically, as long as this chain can access the BTC ecological assets, and the expansion chain that can promote the second prosperity of BTC assets can be classified into the category of BTC Layer2.It seems that the definition of “Layer2” is disrespectful, but a while ago, Vitalik faced Ethereum’s Layer2 inner roll war and proposed to give up the concept of Layer2?
To some extent, BTC Layer2 is now presented by chaotic disorder (entropy Entropy).Turned to clear.
I wrote an article before the analysis of @BSQUAREDNETWORK on the Bitvm challenge mechanism. It also mentioned the abstract design of @Partic Serk and @Bitmaptech on BTC Connect. Map Protocol has been in a long time, and the voices on Twitter are relatively loud.Many friends let me analyze.
To be honest, I didn’t understand it from the beginning.Because, a chain that originally made Layerzero’s interactive operation, suddenly promoted the ALL in Bitcoin Layer2 ecosystem, which always felt a bit of being committed to “narrative”.After all, it is clear that it can be a full -chain narrative. Is it not equivalent to self -restrictions if BTC Layer2 is positioned?
With this question, let’s briefly analyze the technical logic framework of Map Protocol:
The MAP positioning is based on the point -to -point full -chain infrastructure of the light client at ZK, focusing on the point -to -point interoperability of the point -to -point center center.How to do it?The MAP scheme is actually building a MAP relay chain, which is equivalent to the BOB chain chain. The relay chain will compile the signature algorithm of different chains in the contract in the contract. Based on this, you can obtain cross -chain communication and zero -friction asset transfer capacity.
Taking BTC as an example, MAP first deployed the ZK light client on the BTC chain. The light client does not need to download the historical data of the full node, and you can perform some operations on the BTC main network: for example, the Merkle proof of the block header and the transaction -related Merkle proofWhen the two -layer chain requests the currency withdrawal, the main network light client only needs to verify some data related to specific transactions to complete the operation safely.
This is actually the first simple payment verification standard SPV (Simplify Payment Verification) technology defined in Bitcoin white paper technology.
If the BTC main network is regarded as the asset settlement layer, the method of using a light -node client can significantly improve the security of asset transfers of cross -chain transfer, and at the same time, it also avoids the resource loss and cost of the entire node verification.The reason why ZK technology is used is to ensure that the operation of the Layer2 side chain and the main network verification consensus remain consistent.
(Need to clarify that the light client can only verify the payment type, and it cannot verify the status effectiveness on the Layer2 chain, that is, the main network can verify part of the data submitted by Layer2 to verify whether the unlocking UTXO unlocking conditions can be transferred to asset transfer.Verify the more complex state on the layer2 chain)
It should be said that the method of ZK light client+relay chain can indeed realize the safe cross -chain and non -wear conversion of assets.The relay chain will deploy smart contracts that adapt to the full -chain environment (BTC -free contracts such as BTCs use light clients as assets to migrate assets) and follow a set of standards for cross -chain communication, and then cooperate with a set of POS -based interaction and effective validity.Sexual verification mechanism.To do this, it constitutes an interactable operating solution.
It is precisely because Map Protocol has a genetic -based interactive gene, which is positioned as BTC Layer2 and its development path will be different:
1) MAP will focus on the characteristics of BTC’s main network, to enrich your Layer2 function, and allow BTC’s assets. In addition to BTC’s main assets, many inscriptions assets can also safely cross the chain on Layer2.
Because of the strong consensus circulation of a single BTC, it is difficult for any Layer2 expansion plan to leverage the consensus of BTC Holder. If the inscriptions are different.BTC Layer2 can manage and circulate these BTC derivative assets with lower cost, low loss, to achieve the goal of Layer2 expanded BTC’s main network value;
To achieve this goal, it is not as simple as simply put BTC assets to the Layer2 chain, involving the consistency management of the Indexer indexant, compatibility and management of different BTC derivative inscriptions assets, and so on.Obviously, it is the key to develop more expansion performance that conforms to the native characteristics of BTC around the characteristics of BTC derivative assets.
2) MAP will become an interactable operation layer of other BTC Layer2 (layer 0). Imagine that BTC Layer2 is connected to a batch of mature EVM chains and a number of Non-EVM performance chains.The chain is connected in some way, but isn’t the core question interacting for interoperability?Obviously a chain chain in a chain characteristics of a sufficient heterogeneous BTC main network and being compatible with other all -chain environments will become the key.
MAP can choose not to compete for the C position of the Layer2 chain, watch other Layer2 chains compete with each other, and then to tear the market to seven -point cracks, and then integrate and interact the characteristics of its own all -chain interactive operation.Manage liquidity.
In my opinion, this may be a trick.
Of course, during the barren period of BTC Layer2, everyone was squeezing through the heads and grabbing the C position. Among them, there were some plans that regarded the objective defects of the main chain of BTC, and the core of the two -layer chain value was active.Next, if a BTC Layer2 can settle down and find your own ecological card, it is the ultimate point of winning.
