深入解读热门 BTC 二层 B² Network

Bitcoin ecology contains great potential. As the cornerstone of the whole encryption industry, Bitcoin's current market value has reached, but most of the time it is only used as the value storage carrier of encrypted gold. As a rare way for Bitcoin to flow into the field, the current market value of assets mapped by centralized custody institutions is less than the market value of Bitcoin itself. Therefore, there is actually a lot of asset liquidity in Bitcoin network, and the original ecology of Bitcoin has huge potential momentum, which is contrary to widely recognized fact. Bitcoin network does not support smart contracts, but only for the sake of security and simplicity. Although the supported smart contract programming language is not as powerful as Turing, it can still support functions such as multi-signing, time-locking, partial signature transactions, etc., so that the signature information of witness data unlocking transactions has an independent isolation space and the capacity reaches to expand the media types stored in the chain, and the upgrade enhances the privacy of transactions and allows Bitcoin to perform more and more complicated transactions. It is easy to store data in the script path, which has promoted the birth of subsequent agreements, spawned the distribution of new assets and brought about the prosperity of new bitcoin assets, and brought people's attention back to the possibility of bitcoin ecology. Many bitcoins insist that Bitcoin should remain simple and pure and play the role of a good value reserve, but the lack of online activity will actually be harmful to Bitcoin. Take the upcoming bitcoin halving as an example. The reward for each block will be reduced by half, which means that the income of miners will be greatly reduced. If the income cannot make ends meet, it will naturally lead to a reduction in the number of miners, a reduction in the degree of decentralization and a corresponding increase in vulnerability when attacked. There are only two solutions to avoid this situation. Even if the price of bitcoin doubles, the reward income for the block will be balanced with the present or the active online activities will bring more fees, which has been agreed and verified in the two waves in May and December. The tide has greatly increased the income of miners. So far, the income brought by the agreement far exceeds the income of miners. A method often used by developers to measure the security of the network is to evaluate the number of all nodes. In order to enable individuals to run all nodes, the size of the block should be strictly limited and the cost of all nodes should be reduced. From the point of view of the number of all nodes, many people need and interact with each other, which obviously increases the number of all nodes. Obviously, the network needs rich activities on the chain that are ecologically empowered. It only brings economic benefits to miners, makes up for the loss after halving, increases the number of all nodes and increases the network security. More importantly, it makes more people really understand the reason why the mechanism of releasing potential is not applied. Besides the limitation of intelligent contract language, it is also slow and expensive. The important means to expand the capacity of Ethereum is essentially to separate the executive layer with the idea of modular blockchain to improve efficiency and inherit the security of Ethereum network. The past year has also been an extraordinary year for Ethereum. If you want to release the potential of Bitcoin, a natural idea is to build a two-tier network to expand its capacity, and make up for some shortcomings with an efficient and fast virtual machine or a more familiar executive layer. It is a pioneer of the two-tier network, which is based on the zero-knowledge proof of Bitcoin and is compatible. The technical architecture that brings the talent of Taifang to the bitcoin ecological technology architecture mainly includes two layers. The layer and the layer simply understand that this architecture needs a virtual machine to handle users' transactions, and also needs a place to store data to verify transactions. The scheme adopted at the layer will be extended to the world together. Users can use the Ethereum account and the account to interact, and at the same time take care of the common wallets of users with ecological habits on both sides. It can also continue to reduce users' learning costs. The main account can be realized as a sub-account through services, and users' transactions are submitted and submitted at the layer. Processing the user's state is also stored in the layer network, which will generate related zero-knowledge proof package and send it to the layer for storage and verification. The layer includes decentralized storage nodes and the zero-knowledge proof used by Bitcoin network for verification. Finally, the data will be engraved into Bitcoin network by inscription. The whole data flow is as shown in the figure below. After the sorter packages the user transaction data, it will be saved by distributed storage to avoid single point failure and increase reliability. Guaranteeing data availability will write scripts to Bitcoin network in each block to realize the continuity of data availability time. In Ethereum network, the data of the second-tier network is transmitted to the contract on the main network to verify the transaction and save the data. However, Bitcoin network does not support automatic verification of intelligent contracts. Only by writing the aggregated data with zero knowledge proof into Bitcoin, the data guaranteed is anchored in Bitcoin and cannot be tampered with, but it cannot guarantee the validity and correctness of internal transactions. Sex can't be guaranteed by bitcoin's powerful consensus ability. Therefore, the adopted scheme is to write the promise of zero-knowledge proof into the main network, allowing challengers to challenge the promise of zero-knowledge proof verification within a specified time limit. If someone challenges successfully, they will roll back the assets locked by the node, while if no one challenges or fails during the challenge period, they will be finally confirmed on the internet. The design is very clever. First, it reduces the learning threshold of users by using account abstraction, which actually reduces the capital. The threshold of production access is convenient for users to access their wallets wherever they have assets. The two-tier network is compatible, which is convenient for introducing developers and Ethereum ecological migration. A similar hybrid model is adopted to verify data, reduce transaction costs, and the challenge model is adopted to avoid the problem of limited verification ability. The vision is not limited to one, but it has similar or the same ambition to become a two-tier center, which will serve all developers and project parties who want to build a two-tier bitcoin network in the future. Providing data availability layer and state transition verification based on bitcoin network proves that future developers can choose combinations to build their own token economy. In the design, there are many links with decentralized needs. Where there are token incentives, the sorter pledge network realizes decentralized sorter service through nodes. The sorter participates in the sequence verifier election by pledging tokens. The service updates the sorter set through a similar mechanism. The sorter in the sorter set provides transaction sorting and packaging service income in sequence. It is proved that bitcoin will be burned by paying tokens as part of income when settling accounts. 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台
