Trias Talents Opinion丨Lin Guo: How is to Survive the Cold Winter of Blockchain？
There are some talents who change the world a little bit every day. They always believe in technology, but are never limited by it. They are passionate and optimistic about the future but never satisfied with what they have achieved. What is the world likes in their eyes? Starting today, we will begin to uncover for you the secrets that you’ve never heard of.
Lin Guo, as Server Operations Develop Engineer Director of Octa Innovations, is familiar with lockchain including BigchainDB, Ethereum, Hyperleger, Fabric, etc. And he is skilled in Linux, Unix (Solaris) and Windows systems, especially Linux system, with a deep understanding of operating system theory.
Blockchain, one of the most closely watched technologies in recent years, has been described by its proponents as a catalyst that can change the world while opponents calling it the biggest hoax in the 21st century.
Compared with last year’s warmly embracing, the blockchain technology market now cold down, even someone said that its winter has arrived. How to integrate the business mode with blockchain technology, such as BigchainDB, Ethereum, Hyperledger, EOS and other fields has an in-depth study. Setting aside these extreme views, we wonder what blockchain looks like in the eyes of a technology geek.
The following is part of the sharing brought by Lin Guo.
BTC, the first shot to trigger the blockchain
In Helsinki, Finland, on January 3, 2009, Satoshi Nakamoto wrote in the Genesis Block, “The Times 03/Jan/2009 Chancellor on brink of second bailout for banks’. No one would have thought,a system that could change the world economy.
Under the current system management, the centralization situation is extremely serious. Compared with the central institutions, people can only obey their rules. The deficient in centralization network system are obvious, it is not only lacking power checks and balances, but high operating costs.
Blockchain has been widely recognized all over the world, one of the important reasons is that it provides a new trust mechanism based on decentralization through technical means. The blockchain system relies on the multiple participants on the network, and can realize the confirmation of assets and real-time monitoring.
This allows blockchain to be widely used in asset notarization, audit operations, intellectual property protection, and domain name administration. In a word, blockchain strike seriously in trustworthy and the fundamental foundations of human society.
1. Blockchain belief and realistic problem
First of all, it is worth noting that the so-called blockchain is not a single point technology, but a collection. Such as cryptography, data structure, consistent algorithm, network, database, and so on, these technologies have never been short of applications. But mentioned blockchain, it can be iterated and scalable. For technologists, there is a huge space for research and development.
However, neither the world nor technology is static. After the previous booming development, blockchain is now faced how to solve challenges and the high cost pain point.
We know that blockchain is difficult to tamper with the data properties to ensure security. But the blockchain is not a panacea, in the process of practice, it remains its own security problems mainly in the field of private key and system loopholes, all those problems greatly affected the application and promotion of blockchain.
However, in the process of promotion, there is a ‘Value Island’ problem. The Value Island refers to a war between the different chains, information isolated and not shared, each chain is a parallel world. This is clearly not conducive to realizing the value of the information.
The current blockchain world has numerous chains, such as public chain, private chain, main chain, side chain. Even if on large public chain, there are only a few active DApp on it, which has not yet formed a complete ecological system.
Based on the above problems, Trias is committed to building a blockchain framework on the ground. In the consensus layer, the consensus algorithm can be embedded in TEE technology so that more secure and reliable. This part is actually secure and controllable, and the security level can be adjusted based on different industries and consensus security.
In terms of usage cost, Trias provides convenient upper chain interface and technical solutions, including account system and consensus strategy, which makes native application can easily interface with Trias system.
2. How to use TEE to reach consensus?
Combined with the TEE consensus, it will first choose the trusted state node as the consensus participating one. In doing so, TEE first evaluates the security of the node, there will be a layer of security consensus, which will significantly enhance the overall consensus security.
So, what is the trusted structure of TEE? As we know, each node maintains the authentication information between nodes in the network, which is updated with the verification. They represent the trusted nodes in network.
3. How to run TEE data in Network?
The trusted information among nodes will be propagated through P2P network built by Gossip algorithm, and the trusted state of all nodes will be recalculated at a specified time, and then all nodes will be ranked to finally form “SkyLadder”.
It’s worth mentioning that the verification process is not merely one time, but changes every time. And each node is constantly measuring the others credible level. After joining the network, Trias will go through a certain period (it is not fixed, and mainly updated by the entire network computing power, such as 8 days mentioned above) to release the ladder and select the top ranked nodes in order as the super nodes. This is totally different from the EOS voting mechanism.
