What do you think of the cooperation between ParticleNetwork and babylon? In short: Particle's Omini unified entrance built on the chain abstract 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 this in many articles before. In essence, it encapsulates a whole set of interoperability capabilities, mainly including: underlying language compilation, account model compatibility, smart contract standard interoperability, and other component designs that facilitate a 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 various heterogeneous chains, 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 chain communication.

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

Moreover, 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 Relayer is required to be more "safe".

Usually, the underlying POS chain framework needs to pledge native tokens to ensure that nodes do not do evil, but if the price of tokens fluctuates greatly in the early stage, malicious nodes may hoard a large number of tokens to implement governance attacks, which will seriously undermine the stability of the chain. Moreover, an important hub chain like Particle, which 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 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. How to achieve the technical logic?

Babylon uses technical solutions such as time lock, one-time signature EOTS, and final round multi-signature consensus to ensure that users' assets remain on the main network when they cross the chain to the second-layer network, so there is no need to worry about the threat to user assets caused by 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 is that user assets are locked in the main network multi-signature contract through time locks, so that if there is a problem with the second layer network, the user's assets will not be immediately damaged. The high security of the Bitcoin main network provides basic protection for users;

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

The third layer of security, Babylon cleverly uses BTC timestamps to prevent "long-range attacks". Even if the attacker tries 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.

that's all

Based on the above understanding, the value and significance of the Particle+Babylon alliance are self-evident.
