Tension reds said | dialogue jiang fuyao, jiang jiashiji: boca and Cosmos almost stand on the same starting line

Late January 8, tension within the community held the fifth red man said "tension" AMA activity, the theme for the online sharing, "cross chain pair: Polkadot VS Cosmos", by the tension and energy chain lab partner, cinda securities chief the block chain experts Cao Yin, co-chair, interviewed Polkadot early community members Jiang Fuyao, coinex chain chief Jiang Jiazhi developers.

Cao Yin first gave a wonderful introduction to Polkadot, Cosmos and analysis, he said to independent chain such as COINS and etheric fang and his own verification nodes, but can be by connecting bridge link to the card, the chain nodes do not need to use the wave of the card itself Shared state and safety system, need not hosted on the wave card platform, can benefit from boca chain of interoperability.

Unlike poka, the cross-chain in the Cosmos network applies a hub-and-spoke model: the Hub (" hub-and-spoke ") is at the center. The Hub manages a number of separate blockchains called "zones" that track the status of each Zone, and each Zone is obligated to constantly report back to the Hub the new blocks it produces. Similarly, each Zone also needs to synchronize the status of the Hub.

When it comes to poka and Cosmos, the first thing that comes to mind is the cross-chain blockchain project, which is very popular, but few people can explain the characteristics of the two and the difficulty of cross-chain technology.

In the interview, Jiang Jiazhi presents a generalization of a very refined: cross chain is difficult to achieve, there is a lot of technical threshold in the Cosmos is very wise choice to develop a first block chain development framework that can be used by you to develop your own block chain within the framework of the project, you need to use the cross chain, natural to use the IBC protocol, so will a lot of developers to help solve the problem of cross chain.

In other words, Cosmos is a novel way of breaking problems into smaller pieces and motivating developers to solve them together.

Of course, poka has its advantages. Fuyao jiang, an early member of Polkadot's community, is very vocal on this point, noting that the Substrate is designed to be pluggable and modular, and to some extent to pull away from the network layer and the consensus layer. In addition, the Substrate runs most of the chain logic in the form of runtime. When the upgrade is made, all changes to the runtime module can be written into the transaction, and a vote is initiated in the form of a proposal. After passing, all nodes will synchronize with the update of runtime. And complete the runtime update at the specified height, the whole process does not need to pause the node upgrade client, is a real silky seamless upgrade.

No matter how it is designed, blockchain will eventually have to be implemented. DeFi is a key word in this year's New Year trend outlook for investors and media. So, how do the interviewees see DeFi domain and how do they see DeFi combined with Polkadot and Cosmos?

In this regard, jiang fuyao raised a very interesting point: BTC will replace ETH as the main force locked in DeFi.

Bear in mind that BTC, the main collateral in derivatives markets such as BitMEX, is trading at more than $1tn a year. In his opinion, more head capital in the market is concentrated in BTC market, BTC liquidity is 3 times of ETH, market value is 8 times of ETH, historical volatility is far less than ETH, so if open BTC mortgage DeFi market will lead to unprecedented prosperity. At the same time, he was more comfortable with the framework ecology of Substrate.

"I think there will be four directions for DeFi's application: decentralized lending, insurance, real asset chain upstream, and decentralized trading. The blockchain industry is just beginning, DeFi is in the ascendant and there is still a long way to go. Jiang jiazhi finally said in an interview.
