What’s the "impossible triangle"?

Precisely what is the "impossible triangle"?

The so-called "impossible triangle" means that with the blockchain public cycle, it is difficult to quickly attain both good "decentralization" and good "security" of the system. "Transaction Processing Performance. inch The "transaction handling performance" is often called TPS (Transactions Digesting Per Second).

imposible triangle Actually the "impossible triangle" is not a rigorous conclusion. It is just a overview of the actual doing work status of each general public chain in the industry. That is to say, it is not necessarily that the public chain simply cannot do well in the some aspects of "decentralization", "security" and "transaction producing performance", but it have not done well within these three factors at the moment.

Public chain. How is additional public chains?

Nowadays, the most famous court chain projects are generally BTC, ETH, together with EOS.

First of all, you should study the Bitcoin - BTC.

BTC uses a consensus tool based on Proof of Job (POW). In the early days of BTC enhancement, an ordinary computer may participate in mining. Nevertheless later, with the skyrocketing currency price, exploration became profitable, which means that graphics card exploration appeared, and in the future ASIC mining equipments with stronger scheming power appeared, and eventually unified the estuaries and rivers and lakes. That mining of typical computers and artwork cards is completely the past. At present, the construction and production from ASIC mining devices are almost monopolized by Bitmain, as well as the computing power with BTC's entire mobile phone network is almost monopolized by several large mining pools. Therefore , this "decentralization" of BTC seems to be inaccurate to numerous people.

In terms of "transaction processing performance", BTC's TPS is only approximately 7 transactions each and every second, which is completely unsuitable for day-to-day high-frequency and small-value transfers. It is this approach low transaction performance that has caused that BTC community being divided over the upcoming development of BTC. This disagreement isn't properly settled, eventually leading to a hard hand of BTC money in 2017.

In terms of stability, compared with several other open chains, BTC is still the best. On the one hand, the computer power of the comprehensive network is regularly improved with the improvement of the ASIC mining machine itself, and additionally on the other hand, new mining machines are constantly added to continue to improve the computing power in the entire network. Consistent with estimates, the current charge of attacking BTC is the highest off POW public restaurants.

Next, we explain blockchain 2 . 0 Ethereum - ETH. Although ETH is also a consensus infinite triangle mechanism based on proof of get the job done. But it can always use graphics greeting card mining, so the circumstances of computing electrical power monopoly is not as serious as of which of BTC. In addition , the recent overall overall shift to be able to POS consensus to eliminate the problem of computer power monopoly, so it is better than BTC in the case of decentralization.

ETH carries a slightly higher TPS than BTC, but because ETH can be described as smart contract principle, its application scenarios are more complex in addition to congestion is very likely to occur than BTC. As a result, the performance issues that ETH provides exploded have received more attention. Because of this, EOS, which was later very anticipated and troubled, was born.

In terms of protection, ETH is following only to BTC.

We should take a look at EOS which has been so much expected. As soon as EOS first arrived on the scene, TPS was its biggest selling point. Really, the EOS for the once-proclaimed million-level TPS has long since changed, because in fact , the TPS involving EOS is only a couple hundred. But this does not prevent the idea from ranking top in terms of transaction handling speed of the three major public restaurants.

However , in order to achieve this TPS, EOS offers made huge eschew in the degree of decentralization. Compared to the 10, 000 nodes on the general network of BTC and ETH, it has only 21 nodes on the entire network. Therefore , it is the the majority questioned of the several major public organizations in terms of "decentralization".

From your security perspective, due to the fact EOS has simply 21 nodes within the entire network, it truly is relatively easier designed for hackers to impossible triangle harm 21 nodes as opposed to to attack several thousand nodes in BTC or ETH. For that reason EOS is also your worst of the several in terms of security.

Sooner we analyzed some great benefits of some public restaurants and their performance in the "impossible triangle", which is basically the present-day status of open public chains. But in the case of the most promising general public chain technology in recent years, Liberum must be stated.

At present, the basic standard of blockchain technological know-how is the development logic of "low-level open public chain → answer → project application". Therefore , even by 2020, the main concentrate of the blockchain holds the competition of the base public chain plans. It is obviously promoting the development for the entire blockchain sector.

Liberum uses HWD-PoW as the core protocol, while ensuring the decentralization of the open public chain, it nevertheless effectively prevents 51% attacks. By isolating transactions and smart contracts and creating a fixed block generation algorithm, the filter production speed, success rate, latency, server cost, and scalability cost of the Liberum main network need all broken way back when technical barriers, really surpassing the same hidden public market on the market chain.

Facing this impossible triangle, Liberum adopts the unique HWD-PoW innovative consensus instrument to try to optimize the total amount between security together with transaction processing accelerate while maintaining increased degree of decentralization.

You selected three real Ethereum mainnet circumstances for experiments, plus the results were per the official claims. Using the HWD-PoW solution may well indeed increase the strike cost by above 100 times.

In addition , one of the reasons for this inefficiency of old blockchain solutions is normally that all nodes must process the same mission multiple times. Your sharding technology gives more powerful processing strength proportional to the variety of nodes in the system by sharding a nodes. Through sharding technology and revolutionary improvements that isolate transactions from wise contracts, Liberum's leading-edge hierarchical group company system has considerably improved the overall dealing processing speed. In theory, TPS can get through to tens of a huge number. However , it is appreciated that, because Liberum is still in the first stages of development, in order to reduce development difficulty and reduce fritter away of resources, that core team currently has some limitations. Liberum's transaction finalizing speed is for the short term stable at round 20, 000 TPS. But even so, this approach ultra-high TPS comes with thrown EOS, ETH and BTC miles away.

According to the overall examination, Liberum has an unparalleled high speed within the overall transaction digesting speed of the active public chain available to buy, while its specific HWD-PoW innovative total mechanism maintains a healthy degree of decentralization although successfully attacking a attacker to increase spend. The cost of episodes and 51% attacks has also risen to your level that shouldn't be surpassed by many other public chains. It happens to be no wonder that after the new involving Liberum mainnet definitely will launch soon ended up recently, there are many solutions enthusiasts on the market exactly who highly respect the following underlying public company that broke your "processing speed-security-centralization" impossible triangle.

You might have heard about “the impossible triangle” which has triggerred heated discussion in cryptocurrency communities. We will discuss whether it is a true concept or a pseudo one, because only when we can distinguish the authenticity and no longer waste time on the pseudo one, it is possible to explore the issues worthy the [...]
