Who is the cross-chain king between Cosmos and Polkadot

Discussion on the marketArticles on the realization of cross-chain technology of two projectssecondary title

Comparison of core features

Before talking about the core technical features, you need to know,The concept of cross-chainWhat it means and why Polkadot and Cosmos are the real all-stars out there. The concept of cross-chain actually existed a few years ago, including the lightning network on BTC, the side chain on ETH, and some so-called "cross-chain" projects, which can all be counted as cross-chain. However, this kind of cross-chain is more about the cross-chain of assets through two-way anchoring or atomic swap; across each other". After so many years, everyone has discovered that there is a DApp chain, nothing more thanETH，EOS，TRONThree, the chains that can really be counted as "assets" are nothing more than Bit Monero. With just a few chains, do they really need to cross each other?

The next stage of cross-chain is the era of "interconnection of ten thousand chains" led by Cosmos and Polkadot. The so-called cross-chain is more about "chain issuance". Remember Gavin Wood's "magical feat" of building a new blockchain from scratch in 15 minutes at the Web 3 Summit?

Cosmos’ chain-building tool is called Cosmos SDK, and Polkadot is called Substrate. Both of them give developers the ability to “quickly build chains”. The chains generated through these protocols are naturally interoperable; method of linking in.

What is the difference between these two core technical features:

1. Architecture

Cosmos: more concise

Polkadot: more complex

It can be seen at a glance from the structure diagram of the two:

This is Cosmos, simple and clear, a Hub is a chain, and other connected Zones are Hub side chains, and Hubs can be interconnected. The recently popular project IRIS is a Hub on Cosmos.

2. Security

2. Security

Cosmos - more like the United Nations

Polkadot - more like NATO

The price of Cosmos simplicity is a slight decrease in security. After all, you can’t have both. If the central Hub and the regional Zone are different countries, each country has its own army and sovereignty to maintain security.

The most secure must be the Cosmos Hub. After all, among all Hubs, Cosmos native token Atom must have the highest market value. Based on the security model of PoS Staking, of course, the larger the market value, the higher the attack cost, and the safer it will be. Security varies for each of the other Hubs.

Polkadot is similar to NATO, which uniformly allocates military power and deployment, and the military power (validator nodes) of the central Relaychain and regional Parachain are randomly selected and allocated by the Polkadot system. In other words, if the Polkadot main network is secure, all parachains connected to it will be secure.

3. Autonomy and flexibility

Cosmos - more like Android

Polkadot - more like an apple

Autonomy and flexibility are actually the final results of differences in structure and security.

The access threshold of Cosmos is lower, just like developing on Android, as long as you use its IBC standard, you can access the Hub to download at any time, but you are at your own risk. This is why there are more programs and more viruses on Android.

developer perspective

In fact, it is not important to compete with cross-chain technology. Because it is not the so-called capital whales that determine the future of the blockchain, nor retail investors like you and me, nor even project parties like Cosmos or Polkadot. The real decisive force is blockchain developers from all over the world. Only when they develop chains or DApps that ordinary people "really use" can blockchain truly transform the world and embrace the future.

In the past ten years, the projects that have really landed, strictly speaking,Only one BTC. The next ten years will be the decade when the concept of "blockchain" will really bear fruit. So the essence of all public chain competition today is actually robbing developers, not users.

If you are a developer and plan to make aExplosive DApp, then who will be the choice with the lowest comprehensive cost, the easiest to promote, and the most effective option?

JingdongJingdong, Pinduoduo these three.

In the blockchain world, after 2019, developers' preferred platforms must be the three chains of Ethereum, Cosmos, and Polkadot. the reason is simple:

1. Ethereum has the strongest developer community and a huge first-mover advantage. Solidity has become a popular language for getting started with blockchain and has a huge ecosystem. The disadvantages are equally obvious, the current performance is a huge bottleneck, and the final version of "Serenity" is far away, and the very frightening point is that Polkadot can basically do everything that ETH2.0 can do.

2. Cosmos has the best time advantage among the three, and originally this advantage could be bigger (Cosmos’s main network was originally scheduled to be launched at the end of 2017, but it was later postponed until 2019), although it was delayed for nearly two years , but Cosmos is still the first cross-chain star to go live on the mainnet. Before the Polkadot mainnet is launched and before ETH2.0 is finally formed, Cosmos may be the best choice for new project developers, none of them. Binance Dex chooses to develop based on Cosmos, which is the best example.

3. The main network of Polkadot has not yet been launched, but the video of Gavin using Substrate to build a chain in 15 minutes is too impressive. Coupled with Gavin Wood’s huge reputation, after Polkadot was launched, developers flocked to compete for 24 parallel chains. The fiery scene of the chain slot is not hard to see.

Investor's perspective

Some time ago, the Cosmos mainnet was launched, and friends would ask me every now and then, "Can you accept the $3 Atom? car!"

At the time of writing this article, the price of Cosmos token Atom is 4 US dollars, ranking 17th, with a market value of 700 million US dollars. This is also in line with the consistent characteristics of the all-star currency: when listed on the exchange, the top 20 will be airborne directly. So the question is, what is the current price and ranking, and what is the investment potential? Has the potential been exhausted, and only the offer is left?

It depends on when you actually participate!

If it is based on the day or week, then in the near future, unless the market soars, it is unlikely to soar again in the near future. When the main network has just launched and the ecology has not yet been established, the current market value and ranking are really not good. Low. However, if you look at it in months or even years, if you firmly believe thatWanchain InternetIf it is an inevitable trend in the next stage of the blockchain, it would be a good choice to start investing in Cosmos. Believe in one word - the strong will always be strong!

Looking at Polkadot again, many people do not know the founder of Cosmos, and the reputation of the founder of Polkadot is almost second only to Satoshi Nakamoto and V God in the circle, the former CTO of Ethereum, the author of the Yellow Paper of Ethereum, and one of the inventors of Solidity , the inventor of the Parity client, the founder and president of the Web 3 Foundation, the founder of Polkadot... too many dazzling halos added to the body; what's more: Gavin is so handsome...

Polkadot is almost the only project that has obtained the capital consensus, elite consensus, and leek consensus before it goes public. The cost of ICO in the first round in 2017 was US$30, and the valuation in the second round recently was US$100. If we look at the second round of prices, if all of them are unlocked, the market value of 1 billion is exactly the same as that of Dash, which is currently ranked 14th.

Below, we compare Polkadot with Atom:

1. Cosmos is currently able to achieve cross-chain token transfers, while Polkadot is designed to achieve any form of DApp interoperability, so in terms of functionality alone, Polkadot is more powerful. Of course, this power also has high development costs and a more structured architecture. The price of complexity.

2. As I just said, the founder of Polkadot has a halo bonus.

3. The function of the Cosmos token Atom, after Staking, can only realize the self-security of the Cosmos Hub, and cannot make security contributions to other Hubs. Polkadot's token, Dot, is responsible for the security of all parachains connected to the relay chain.

Another point is that the emergence of Cosmos and Polkadot will have an important impact on the entire public chain and cross-chain ecology. Do not believe? Let's wait and see next year...
