BEVM launches Super Bitcoin technology framework to build Bitcoin consensus security value Internet

Original source: BEVM

The Bitcoin ecological entrepreneurial team BEVM (Bitcoin-Enhanced Virtual Machine) recently released the Super Bitcoin technical framework, with the goal of creating a value Internet with shared Bitcoin consensus security.

The author read the Super Bitcoin white paper as soon as possible, and I suggest that everyone can read this white paper. The white paper is full of essential thinking about Bitcoin expansion plans, and it is also very forward-looking about the current situation and future predictions of many L1 public chains and L2. At the same time, we can also see the BEVM team's calm observation of the current Crypto industry and the team's ambitions.

This article will comprehensively interpret the Super Bitcoin white paper and some of my own thoughts from the following points.

1. What is Super Bitcoin?

2. Super Bitcoin's five-layer architecture

3. The core of Super Bitcoin - sharing Bitcoin consensus security

4. Why is there only a future for the expansion plan that shares Bitcoin consensus security?

1. What is Super Bitcoin?

Super Bitcoin is a new five-layer technical architecture launched by the BEVM (Bitcoin-Enhanced Virtual Machine) team, which integrates the Lightning Network, Taproot Consensus and BEVM-Stack. Super Bitcoin is a network built on the basis of Bitcoin consensus security and can expand Bitcoin infinitely. The vision of Super Bitcoin is to build a value Internet that can share Bitcoin consensus security, which is also the ultimate goal of the BEVM team.

From this series of descriptions, we can see that the Super Bitcoin solution proposed by BEVM has gone beyond the scope of the Bitcoin second-layer network, but is firmly rooted in the Bitcoin network. By integrating the Lightning Network and Taproot Consensus, the consensus security of Bitcoin is shared through the Super Bitcoin technical framework. Super Bitcoin serves various chains that want to share the Bitcoin consensus security and various decentralized Bitcoin applications on the chain.

2. Specific technical implementation of Super Bitcoin

Super Bitcoin proposes a five-layer structure, as shown below:

As can be seen in the figure, Super Bitcoin uses Bitcoin as the basic layer of the network, and the entire network is completely built on the security of Bitcoin's ledger. How is it built? It is through the Lightning Network. Why is it the Lightning Network? Because the Lightning Network is currently the only second-layer solution that can share the security of Bitcoin consensus. However, the Lightning Network can only be used for payment, and there is no way to make more complex expansions?

Good question, this is the problem that Super Bitcoin wants to solve.

The Lightning Network is the only Bitcoin second-layer network built according to Satoshi Nakamoto's ideas and the Bitcoin white paper so far. From its proposal to its implementation, the Lightning Network has always received much attention and support from the global Bitcoin community users. Almost no one in the world doubts the security of the Lightning Network, because the Lightning Network completely inherits the security of Bitcoin. In essence, the Lightning Network is the Bitcoin network's own fast payment channel.

However, in addition to payment scenarios, the Lightning Network has no more scalable scenarios. For example, it is almost impossible to run smart contracts on the Lightning Network. However, the Super Bitcoin framework proposed by the BEVM team provides a solution.

Those who understand the principles of the Lightning Network know that the BTC in the Lightning Network is locked in the Bitcoin layer and is controlled by the private key holder. The whole process only requires the establishment of a state channel between two nodes, and then the injection of BTC. The whole process is completed on the Bitcoin chain. There is no cross-chain process, and there is no custody. The BTC in the state channel can be paid quickly and at almost zero cost. At this time, the ledgers of both nodes only need to update the status. At the moment of ending the transaction, the state channel is closed, a transaction is submitted to the Bitcoin main network, and the verification is completed, and the transaction is completed.

However, the only flaw is that the Lightning Network does not support smart contracts and cannot achieve more complex expansion. At present, the Lightning Network nodes are all point-shaped. A certain organization or individual runs a Lightning Network node, and then the nodes establish state channels to achieve fast Bitcoin peer-to-peer payments.

In order to achieve more complex smart contract scenarios, Super Bitcoin creatively upgrades the Lightning Network node to a chain that supports smart contracts. Then, any Lightning Network node can establish a state channel with this chain-shaped Lightning Network node (Super Bitcoin). Then, a large amount of BTC can enter the expansion layer with smart contract functions without cross-chain and custody, thereby expanding Bitcoin's applications.

Super Bitcoin does not change any rules of the Lightning Network, but only upgrades the nodes of the Lightning Network to chains with smart contract capabilities. By allowing a chain with smart contract capabilities to serve as a Lightning Network node, BTC that enters this state channel can achieve the expansion of smart contract applications. This solution is indeed very simple and elegant. The key is that it fully inherits the technical advantages of the Lightning Network and shares the consensus security of Bitcoin.

In the technical framework of Super Bitcoin, the Lightning Network is the only second-layer network of Bitcoin. Then, Super Bitcoin creatively combines Taproot Consensus with the Lightning Network to create a chain-like Lightning Network node with smart contract capabilities, thereby bringing BTC into a safe and scalable environment, which is called the expansion layer, which is the third layer of Super Bitcoin.

Taproot Consensus is a solution created by the BEVM team combining the three technologies of Schnorr signature, MAST and Bitcoin SPV node brought by Taproot upgrade. The main goal of this solution is to decentralize the management of a Bitcoin Taproot address through a node network maintained by BFT consensus, and this Taproot address is the core of building a chained lightning network node. Because the security of this lightning network node is protected by a network maintained by BFT consensus.

Of course, even if the chained node of Super Bitcoin is offline or the network is paralyzed, it will not affect the user's BTC security, because all BTC are on the Bitcoin mainnet, and users can get their BTC back by initiating a challenge (this is a function of the lightning network), so, to some extent, Super Bitcoin has its own escape hatch mechanism.

So, after BTC can enter the extension layer without custody and cross-chain, what is the next step?

This is the fourth layer of Super Bitcoin, the Fusion Layer. The main function of the Fusion Layer is to abstract the functions of the first three layers, and then modularly output them to any mainstream virtual machine (MultiVM), so as to share the consensus security of Bitcoin with any Lightning Chain built on the Fusion Layer.

It is necessary to explain here that BEVM exists as the main chain of Super Bitcoin (System Chain, which is a special Lightning Chain). In the future, there will be many Lightning Chains and System Chains interacting. On the Lightning Chain, many Bitcoin applications that can share the Bitcoin consensus security will grow. This is the application layer above Lightning.

The above is the five-layer architecture built by Super Bitcoin. In summary, Bitcoin is used as the most consensus-based and secure basic layer; the Lightning Network that shares Bitcoin consensus security is used as the second layer of asset communication; the Lightning Network and Taproot Consensus are integrated into an extension layer, and Bitcoin consensus security is shared upward to the Lightning Chain on the fusion layer. Finally, various decentralized Bitcoin applications grow on the Lightning Chain.

In the five-layer architecture of Super Bitcoin, one point that is repeatedly emphasized is shared Bitcoin consensus security. It can be said that Super Bitcoin has a reason to exist because of shared Bitcoin consensus security.

So, why is shared Bitcoin consensus security so important?

III. The security core of Super Bitcoin - shared Bitcoin consensus security

What is shared consensus security? Super Bitcoin There is a special section in the white paper to introduce the importance of "shared consensus security".

So, what is consensus security?

Consensus security refers to the fact that in a blockchain network, nodes use a consistent consensus algorithm to ensure the security and validity of transactions. For most blockchain networks, consensus security means that most nodes in the network need to reach a transaction consensus through some form of verification mechanism to resist external attacks or tampering.

It can be said that consensus security is the core of blockchain, and consensus security is the highest level of security, because Consensus security is the maintenance of network security by all chain nodes at the consensus level.

So, what is shared consensus security?

Shared consensus security means that some blockchains can borrow the consensus mechanism of the main chain to ensure their own security. This means that even if transactions are conducted on the second layer, side chain or parallel chain, users can still enjoy the security protection of the main chain level. For example:

1. Polkadot and parallel chains:In Polkadot's architectural design, the main chain (Relay Chain) is responsible for providing global security, while each parallel chain ensures its own security by sharing the consensus mechanism of the main chain. Parallel chains can focus on their specific functions without sacrificing security because they rely on Polkadot's main chain consensus.

2. Ethereum and Ethereum Layer 2: Ethereum's Layer 2 solutions, such as Optimistic Rollup and ZK-Rollup, use the main chain's security mechanism to ensure the transaction security of Layer 2 by recording simplified transaction status on the Ethereum mainnet. This means that although Layer 2 can handle a large number of transactions independently, its security still relies on Ethereum's PoW/PoS consensus mechanism.

3. Bitcoin and Lightning Network Lightning Chain: The Lightning Network is currently the only second-layer network that shares Bitcoin consensus security. State channels are established between Lightning Network nodes. The opening of a channel involves creating a multi-signature output on the Bitcoin blockchain, while closing requires broadcasting the final state to the main chain, which is the core mechanism for Lightning Network to share Bitcoin consensus security. Each channel state update generates a new commitment transaction, which can be broadcast to the Bitcoin mainnet when needed. The design of the commitment transaction ensures that even if one party to the channel does not cooperate, the other party can still close the channel and obtain the funds it deserves by broadcasting the latest commitment transaction. This mechanism directly relies on the consensus rules and security of Bitcoin, so that the security of the Lightning Network is actually guaranteed by the Bitcoin network, that is, it fully shares the consensus security of Bitcoin.

Through these examples, we can see that the core of shared consensus security is that it enables developers to create sub-chains or second-layer networks with independent scalability while maintaining the security of the main chain level.

So, how does Super Bitcoin specifically share Bitcoin consensus security?

Existing BTC Layer2 solutions usually ensure security through cross-chain, multi-signature or BTC pledge. These methods are not to share Bitcoin consensus security, but to achieve relative security through joint signature mechanisms (cross-chain and multi-signature) or economic game mechanisms (BTC pledge). In contrast, Super Bitcoin is built on the basis of the Lightning Network, using HTLC (Hash Time Locked Contract) and commitment transactions, and its security is completely dependent on BTC consensus. This design enables the Super Bitcoin system to fully inherit the consensus security of the Bitcoin network.

Specifically, Super Bitcoin achieves shared BTC consensus security in the following ways:

1. Use the point-to-point channel of the Lightning Network to ensure that all transactions can eventually be settled on the Bitcoin main chain.

2. Use HTLC commitment transactions so that each state update is protected by the consensus of the Bitcoin network.

3. Through the Taproot Consensus extension layer, the security features of Bitcoin are extended to more complex smart contract environments.

4. In a multi-chain system, all Lightning-chains share the consensus security of the Bitcoin network to ensure the consistency and reliability of the entire ecosystem.

So, why does Super Bitcoin attach so much importance to shared Bitcoin consensus security?

Because only Bitcoin expansion solutions that share Bitcoin consensus security have a future.

Fourth, why only Bitcoin expansion solutions that share Bitcoin consensus security have a future?

Bitcoin has become one of the most popular cryptocurrencies in the world because of its unparalleled security. Bitcoin's PoW consensus mechanism makes the network extremely difficult to attack, and any attempt to destroy its network requires huge computing resources. It is this mechanism that gives Bitcoin extremely high security and decentralization.

If a Bitcoin expansion plan cannot share Bitcoin's consensus security, it is tantamount to building a new chain with independent consensus, whose consensus needs to be built from scratch, and its network security has nothing to do with Bitcoin. The reason why the Ethereum second-layer network is established is that most Ethereum second-layers share the security of the Ethereum ledger, and the essence of people's trust in the Ethereum second-layer network is to trust the security of Ethereum.

Therefore, as a Bitcoin expansion plan, it must share Bitcoin's consensus security to be established, otherwise it will be meaningless.

Thinking along this line, we can even deduce why there are so many new public chains in the history of Crypto, but there are very few new chains that are truly successful.

Because, no matter how great the technology of a new chain is, or how sexy the narrative is, these are all based on the "trust assumption". These new chains are all re-establishing new consensus from scratch. It can be said that the consensus of these chains is zero at the beginning. The reason why developers and community users are willing to try is based on the "trust assumption".

If you want to evaluate the consensus strength of a chain, the market value of the chain's token is the most intuitive standard.

The current market value of Bitcoin is about 1.4 trillion US dollars, the current market value of Ethereum is about 300 billion US dollars, and the market value of tokens of other new chains is basically 10 billion US dollars, or even less than 10 billion US dollars.

From the perspective of token market value, it is very intuitive to evaluate the consensus size of a chain (although this is a social consensus based on the value of tokens, it can reflect the size of a chain consensus to some extent, after all, the market votes with real money).

Undoubtedly, Bitcoin is the chain with the largest consensus in the Crypto field, followed by Ethereum, and Ethereum's Layer2, because it can share Ethereum's consensus security, can have a consensus comparable to or even stronger than most new public chains from birth (this can be verified by the fact that most Ethereum Layer2s are valued at tens of billions of US dollars).

In theory, the valuation of Bitcoin Layer2 should be greater than Ethereum Layer2 or even greater than Ethereum's market value. Therefore, if we rank the consensus strength of these chains in terms of theoretical value:

Bitcoin > Ethereum > Bitcoin Layer2 > Ethereum Laye2 > New Public Chain

However, most Bitcoin Layer2 valuations on the market remain within the 1 billion US dollar valuation. Why is this? (In theory, the valuation of Bitcoin Layer2 should be more than 4 times that of Ethereum Layer2, because the market value of Bitcoin is more than 4 times that of Ethereum, and the consensus strength of Bitcoin Layer2 should also be more than 4 times that of Ethereum Layer2)

There is only one reason, that is:

Currently, most Bitcoin Layer2 do not share Bitcoin's consensus security. Developers and community users have no trust in these so-called Bitcoin Layer2s (basically they are all multi-signature and cross-chain, how can we trust them?)

However, looking at the Lightning Network, without any token incentives, it has been able to attract 5,000 BTC to circulate in the network for many years. This data has exceeded the vast majority of so-called Bitcoin Layer2s that rely on token incentives to attract BTC.

There is only one reason, that is:

The Lightning Network fully shares Bitcoin consensus security. People choose to use the Lightning Network because they trust the security of Bitcoin.

So, as a Bitcoin expansion plan, whether it can share Bitcoin consensus security has become the most important criterion, because it almost involves the life and death of the project.

Only expansion plans that share Bitcoin consensus security have a future!

Summary:

This article introduces the Super Bitcoin technical framework launched by BEVM in detail, directly hitting the biggest pain point of Bitcoin expansion plans - sharing Bitcoin consensus security. On this basis, a complete five-layer architecture is proposed to achieve unlimited expansion of Bitcoin while sharing Bitcoin consensus security.

At the same time, this article discusses in detail the importance of "shared consensus security" and "shared Bitcoin consensus security" for Bitcoin expansion solutions, and draws the final conclusion that only expansion solutions with shared Bitcoin consensus security have a future. At the same time, this conclusion has a significant reference significance for evaluating the value of new public chains and L2. I believe that it will also be inspiring for entrepreneurial teams that are currently developing Bitcoin expansion solutions and entrepreneurs of new public chains.
