If there is no accident, Web3.0 concept and cross-chain technology will become important competition points for crypto enthusiasts, which will gradually overtake closed networks such as Bitcoin-Ethernet and promote the resonance of open source networks to maximize the role of the whole chain, and become an emerging way to solve industry problems such as inefficient silo effect.
As early as 2016, the concept of cross-chain has been on the rise, and in 2019 the trend of cross-chain competition was formed, but due to the technical implementation and other multi-dimensional problems, the last two years have experienced the elimination of the strongest and stronger situation, like Polkadot, COSMOS has become the “king class” in this circle. The existence of the project. Nowadays, we need to know what other public chains with “cross-chain” label exist in this blue ocean track, and what is the progress of their respective development?
What is a “cross-chain” type of public chain?
The opposite of the term “cross-chain” is the closed single-chain, that is, the model chain represented by Bitcoin, Ether, etc., which is only limited to its own network growth, compared with the single-chain, the cross-chain public chain can achieve a greater range of connectivity, such as Polkadot, which can achieve cross-chain interoperability and combinability of business ecology development between parallel chains by building a basic framework of parallel chains and linking to the main chain. The value of this network system will be further extended outward through the cross-chain bridge to continue to connect applications and protocols outside the main network, maximizing the multi-directional movement of the whole blockchain network, and thus constructing a huge network system with “multiple concurrent chains and mutual support of chain capabilities”. Based on such infrastructure, more unforeseen innovations will be born. In short, cross-chain ecology is the key to realize the next generation of web 3.0, which solves the core problem of value exchange and interoperability of value silos, and realizes the interconnection of blockchain. The significance of cross-chain lies not only in the increase of blockchain scalability, but also in the means to achieve exchange and interoperability between different blockchains. The current cross-chain implementation methods are mainly as follows.
What is the current status of cross-chain type public chain projects?
The internal architecture and technology development of cross-chain projects are very difficult, and it is not easy to build a chain by copying the code overnight, and it will experience a lot of technical practice in the creation of the overall underlying changes. Therefore, this is why the concept of cross-chain projects is very hot, but the developers have not formed a substantial scale, presenting a dumb fire situation of “sound first but not yet seen”, at this stage, the cross-chain representatives are still mainly Polkadot and Cosmos, and other cross-chain solutions are more of an add-on supplement.
Polkadot:The god of cross-chain in heterogeneous network
There are many introductions about Polkadot in the market, but we still need to mention it first. First of all, Polkadot has been developing cross-chain projects without fail, and the developers, represented by Garvin, have been focusing on the overall implementation of the technology since the beginning, and the support policy of Web3 Foundation shows a “community autonomy” spirit for the parallel development of the project; secondly, Kusama auctions have always been highly anticipated, even if Secondly, Kusama auction has always been highly anticipated, and even after several “maybe in a few weeks” pigeon news, it did not make followers complain until it appeared in such a market environment. Once again, the second chain of the parallel chain slot auction has been created, and with the settlement of more parallel chains, the dawn of “cross-chain” operation will be ushered in, which has the demonstration and exemplary role of an opener for the whole blockchain industry. The final result, at least, opens the curtain of the cross-chain drama.
According to the official news of Poca, XCMP, parallel threads, bridge between Kusama and Poca, etc. will be updated to the network through the forkless upgrade. Next, multiple parallel chains connected to Kusama/Poca can run in parallel, which will increase the transaction processing capacity several times, and then may give birth to some new applications and business models that we can’t imagine in the current state, and it is hard to estimate and imagine what kind of new applications and new models will be unlocked.
Cosmos: A cross-chain network built by Hub and Zone
As early as a few years ago, Cosmos was no less popular than Boka, and was the necessary talk of the “cross-chain” theme in those years. It’s only in the past two years that it’s been slightly weaker. Cosmos is a network of independent blockchains called “Zones”, and The Cosmos Hub is the first Zone in the Cosmos network and the home base of all the Zones. Cosmos places great emphasis on autonomy and wants each chain to have a freer and more autonomous cross-chain ecology, with each chain being able to maintain its own security, so there are different verifier nodes in the Hub and the Zone.
Cosmos has three important parts in technology: Tendermint, Cosmos SDK and IBC. tendermint is the consensus engine and BFT consensus algorithm. In simple terms, Tendermint ensures that transactions are recorded in the same order on different machines, and supports processing transactions in any computer language, saving the time required for development. IBC is an inter-blockchain communication protocol that enables connections between different blockchains (Zones in Cosmos).
The latest news shows that the Cosmos Hub of the cross-chain project has over 100,000 ATOM delegates and 330,000 ATOM accounts. on June 20, Osmosis, a decentralized exchange based on Cosmos, went online. According to the introduction, Osmosis is a decentralized exchange based on Cosmos. Through Osmosis, users are able to trade assets in the Cosmos ecosystem and provide liquidity to trading pairs, and will first support trading of Cosmos assets applying the Interchain Communication ( IBC ) protocol.
Aelf: a parallelized blockchain framework based on multi-level sidechains
Aelf is committed to providing users with a high performance, good experience and trustworthy large-scale commercial blockchain infrastructure, creating an open blockchain network specifically for the new economy, providing unlimited scalability through a multi-level main-side chain system with cross-chain collaboration mechanism, effectively realizing resource isolation and “one chain, one scenario”. According to the official website, the project implements the main chain and side chain of the main network to start step by step. At present, it has entered the main network start-up security observation period, and will then enter the coin exchange period, node campaign period, perfection period and stability period in turn. Nowadays, Aelf has little market action, and its token ELF price has lost its scenery in 2018, and is now quoted at around $0.18.
Avalanche: a two-tier network structure derived from the Paxos algorithm
Avalanche avalanche protocol is closely related to IC3, the top academic team of blockchain. It was derived from the Paxos algorithm and later received $6 million in funding led by coinbase and others in February 2019. The avalanche protocol creates a “sub-stable collapse” concept, where a single node starts to collapse towards its neighbors, eventually forming an avalanche until consensus is reached. The team also created a two-tier network structure that allows applications to customize sub-networks and for the sub-networks to interact with the main network, which forms the final consensus through the Avalanche Protocol. In February this year, the Avalanche protocol (Avalanche) was launched with a two-way cross-chain bridge (AEB) to the Ethernet network. With the advantage of high performance and low fees, smart contract activities on the Avalanche protocol have flourished, and project cooperation has started one after another, with corresponding representative projects in the DeFi and NFT fields.
Near: A sharding solution analogous to ETH 2.0
Near is a PoS public chain using sharding technology. its main team has built one of the few sharding database systems in the world, and now they apply their original sharding experience to the blockchain field. near’s sharding technology has also been affirmed by ethereum founder Vitalik, saying that Near’s sharding technology makes him feel anxious.
In addition to these, there are Achain, the first domestic multi-chain parallel public chain, Wanchain, a cross-chain framework for heterogeneous chains, BitXHub cross-chain platform launched by Funchain, Wecross cross-chain platform launched by Weizhong in 2020 and BCP, a trusted cross-chain platform launched by Baidu in 2020, etc. All of them are the new trendsetters in this big wave of cross-chain, only There is no more creation discovery yet, and the whole is in the stage of muffled technology. In such a market pattern, we can only discover slowly who has the opportunity to go longer on the road of “cross-chain” and so on.
