All blockchain networks have one thing in common: transactions need to be verified. For example, bitcoin adopts Proof of Work (PoW), the so-called mining, which requires a lot of electricity. Proof of Stake(PoS) is another kind of consensus mechanism, which has different evolution and integration forms. We call it staking.
The NYSE parent company, ICE, originally planned to launch the Bakkt Bitcoin Futures Exchange in December 2018. Due to various reasons, it was delayed until the July 23 when the global user test of bitcoin daily and monthly futures contracts was finally launched. It finally went online on September 23.
The glamor of Bakkt not only comes from its compliance attempts in physical delivery, but also its traditional financial background and strong investment institutions.
There is an “impossible triangle” problem in the blockchain industry, that is, the security, scalability and decentralization. People can only achieve the other two by sacrificing the third one. In order to “solve” this impossible triangle, people have thought out many solutions, including the Layer 2.
Now, let’s make a brief introduction to Layer 2.
This is not an article with conclusion. It only aims to trigger heated discussion and exploration on the concept known by almost everyone in the blockchain field: the impossible triangle.
We will discuss whether it is a true concept or a pseudo one, because only when we can distinguish the authenticity and no longer focus and waste our development on the pseudo one, it’s possible to explore the issues in the blockchain which really need to be focused and solved.
We often read the news of some coins being burned. So, what’s coin burning? How is the coin burned? Why should the coin be burned?
Now, we’d like to answer the three questions.
In terms of the blockchain scalability, we have kinds of consensus mechanism optimizations, such as Tendermin and Sharding. The new solutions decouple the time and state updates, propose the program for asynchronous processing of transactions. Will the blockchain scalability be redefined therefore?
Since the blockchain has become a new novelty of entrepreneurship, the project with the concept of decentralized storage in blockchain has become very attractive from time to time.
Facing the temptation of trillion data storage market, many entrepreneurs have targeted at the business opportunity.
The long-anticipated Facebook cryptocurrency Libra white paper has been released finally. Now, join us to have a look at what cryptocurrencies Libra has “referred to”.
At a time when blockchain and cryptocurrency waves are sweeping across the world and the vague prospects of central banks on cryptocurrencies, many large cities worldwide seem to rush to introduce their own regional cryptocurrencies.
In Asia, Japan, South Korea, Chinese Taiwan; In Europe, Britain, Norway, Sweden, Ukraine; In America, Canada; In Africa, Orania … According to public statistics, more than 14 countries and regions in the world have launched exclusive “city cryptocurrency”.
EastShore will make a detailed introduction of the city cryptocurrency in this article. No matter whether they are successful ones, they will provide a new paradigm template for the development of blockchain and cryptocurrency.
DAG (Directed Acyclic Graph) is a kind of distributed ledger technology different from the mainstream blockchain. Since it can upgrade synchronous accounting to asynchronous accounting, it’s widely believed to solve the high concurrency problem of traditional blockchain as an innovation from capacity to speed. However, is DAG technology really so powerful?
This article aims to introduce the architecture, development trends and typical applications of DAG technology to the readers to provide a new idea on the development of blockchain.
