StandardChain, why cross the chains?
On the vast ocean of cryptocurrency across chains, floating a beautiful islands, each island represents a public chain.Due to the barrier of the sea water, the island and the island cannot reach each other.Reflected in the real blockchain world, because different kinds of public chains, alliance chains and private chains have different underlying architectures, different data structures and different interface protocols, it is extremely difficult to realize the mutual visits of one chain and another chain, especially between heterogeneous chains.In addition, there is an important reason why — — smart contracts are not available enough.
Whether it is the architecture, running environment, or update design of smart contract, smart contract cannot achieve complex logic.With the development of new blockchain businesses such as DeFi, people naturally have higher expectations and requirements for Dapp, and the complexity is getting more and more beyond the scope that smart contracts can support. Therefore, many people have pointed out that “ the successful Dapp in the future may not be a smart contract, but a separate chain!」
As we know, all the theory across the chain began with Adam Back paper Enabling Blockchain Innovations with Pegged Sidechains, the paper explains how to transfer assets X from block chain A to block chain B-the so-called “transfer” is actually an illusion, asset X is not “transfer”, but temporarily lock on block chain A, and on the block chain B to generate the same amount of equivalent assets X.This approach is called anchoring (Pegging).If two directions “transfer” to each other (Two-waypegging, 2WP)
