Analysis of Patile Network and Babylon introducing the dual staking model to the public chain

What do you think of the cooperation between ParticleNetwork and babylon? Simply put: Particle's Omini unified entrance built on the chain abstraction framework needs to coordinate and handle a large number of cross-chain communications and transactions. After introducing Babylon's Dual Staking model, the dual security of $PARTI +$BTC can provide "double insurance" for the underlying security operation mechanism of the Particle POS chain. Next, let me briefly talk about my understanding:

1) The chain abstraction L1 network provided by Particle Network is built on the modular underlying architecture of Cosmos SDK, which enables it to simultaneously connect the EVM environment, BTC stateless chain environment, and other POS chain environments that support smart contracts.

I have analyzed it in many articles before. In essence, it encapsulates a complete set of Interoperability capabilities, mainly including: underlying language compilation, account model compatibility, smart contract standard intercommunication, and other component designs that facilitate unified user UX experience, etc.

To become a unified access entry chain linking multiple heterogeneous chain environments, Particle Chain must ensure that it is a very powerful POS chain, and then can realize a unified full-chain account. The general contract of the Particle chain will schedule the synchronization and verification of accounts and status information on each heterogeneous chain, the routing and processing of cross-chain information, etc. For non-smart contract chains such as BTC, Particle has specially launched BTC Connect to realize the communication and interconnection between BTC native wallets such as Unisat and EVM Compatible POS chains. The implementation mechanism will be more complicated than the normal POS inter-chain communication.

If you are familiar with the logic of the IBC relay processing mechanism of Cosmos, you will understand that Particle Chain needs to deploy sub-contracts on other heterogeneous chains, and use the general contract on the main chain to monitor transactions and status updates on each chain, and respond to and handle a large number of demands in an orderly manner.

In addition, Particle has realized many interactive experience upgrades based on chain abstraction. The limited interaction perceived by users will be followed by more complex contract interaction logic. Particle accepts users' complex intent operation instructions through decentralized Bundler services and performs complex Solver processing. In this process, the coordination work of the Relayer relayer is required to be "safe".

Usually, the underlying POS chain framework needs to ensure that the nodes do not do evil by staking the native tokens, but if the price of the tokens fluctuates greatly in the early stage, malicious nodes may hoard a large number of tokens to achieve governance attacks, which will seriously undermine the stability of the chain. Moreover, an important hub chain like Particle that coordinates a large number of inter-chain communications cannot tolerate any mistakes in its consensus governance layer.

2) Recently, Babylon received a huge amount of financing led by Paradigm, and its Native technical security mechanism has been recognized by the industry. As one of the earliest public chains to launch the Babylon Dual Staking dual staking model. The goal of the cooperation between Particle and Babylon is to "strengthen" the security mechanism of the underlying POS chain.

Since both parties have deep integration and application in the BTC ecosystem, the strong combination will directly upgrade the security underlying architecture of the Particle chain to a higher level. Technical logic, how to achieve it?

Babylon uses technical solutions such as time lock, one-time signature EOTS, and final round multi-signature consensus to ensure that the assets of users who cross the chain to the second-layer network remain on the main network, so there is no need to worry about the threat to user assets caused by the malicious behavior of the second-layer POS chain. Specifically, Babylon has realized a "layered" asset security model by combining multiple technologies:

The first layer of security, user assets are locked in the multi-signature contract of the main network through time lock, so that if there is a problem with the second-layer network, the user's assets will not be immediately damaged, and the high security of the Bitcoin main network provides basic protection for users;

The second layer of security, the conditions for users to be attacked on the second-layer network are difficult to achieve. Constrained by the final round of multi-signature consensus, the attacker must not only pledge the native token on the second layer, but also lock a certain amount of BTC on the BTC main network. Even if the attacker can obtain the "governance" right through the low-priced second-layer token, to truly succeed, he must have the corresponding main network BTC assets. This "cost" of doing evil is so high that ordinary nodes dare not even think about it.

For the third layer of security, Babylon cleverly uses BTC timestamps to prevent "long-range attacks". Even if the attacker attempts to fork the second-layer chain, he still has to fork the longest chain of the main network. Considering the huge computing power and security of the Bitcoin main chain, the difficulty of such an attack will obviously be astronomical;

Based on the above understanding, the value of the alliance cooperation between Particle and Babylon is self-evident.
