If your technology doesn't scale, it probably doesn't have any meaning at all. At least, in the real world there is no use in any sense.
Blockchain-based media is no exception. In order to be able to apply in the media domain, blockchain technology must be scaled up to accommodate and increase user and deman

This article will give you a brief introduction to the knowledge about BlockChain and use Python for a simple implementation. Let's take a look at the details below:

A real blockchain is a data structure that is logically linked from the back to the block that contains the transaction information. It can be stored as flat file, which contains files with no relative relational records, or stored in a simple database. Bitcoin core clients use Google's LEVELDB database to store true blockchain
Reliability Comparison
The reliability of blockchain mainly investigates three aspects of blockchain network, shared ledger and account system.

0x00 IntroductionBlockchain (Blockchain) is one of the most revolutionary technologies of the 21st century, and it is still in its maturing stage, and its development potential has not been fully realized. Essentially, a blockchain is just a distributed database of records. But it's unique because it's not a private database, it's a public database, which means that every person who uses it has a full or pa

Blockchain technology is now very hot, not only for financiers and venture capital to flock to, and now has been sown in many fields everywhere. As an entrepreneur with sharp tentacles, do you want to integrate blockchain into your existing applications, and as an IT technical engineer, are you eager to practice a hand based on blockchain to avoid being eliminate
Blockchain trend technology has entered the technology market since its launch. In a short time, it became the headlines and sudden news of newspapers and news channels respectively. In this case, the development of blockchain attracts many entrepreneurs.Experts claim that in the next few years, this technology world will become a blockchain world, and every comp
question of the Byzantine general
Four generals discuss the timing of the attack on Byzantium, in which any three of them can agree and win. As a result of their lack of mutual trust, they could not be in the same room and could only express their views to other generals through correspondence, for example, in the first round of communication, there could be 4 generals. So, how to coordinate, let everybody's attack time coincide. In such a case, if 40 people, or more people, how to coordinate i
If the consensus mechanism is the core of the soul of the blockchain, then for the blockchain, especially the alliance chain and private chain, cross-linking technology is the key to realize the value network, it is to save the alliance chain from the separate isolated islands to rescue the medicine, is the blockchain outward expansion and connection of the bridg
Blockchain is one of the hottest technical terms of the last two years, and it is considered to be the core technology that has the potential to trigger the fifth round of disruptive revolutions, and most people are consensus about how the blockchain really changes the world. With the traditional industry gradually joined the block chain army, I found in the actual block chain, we have a lot of common misun
Blockchain, simply put, is like a database ledger, which records all the general ledger of historical transactions and is the underlying technology of Bitcoin. However, because of the deviation of the domestic cognition, the blockchain has not been universally accepted in China, so its application is seldom used. But in Beijing Cornerstone trillion Industry Holdings Co., Ltd. CEO Wang Dong, the entire

Interpreting blockchain, soft fork and hard fork
Recently in the Exchange Group and the forum often hear soft fork and hard fork, at first, this concept is simply considered to be a blockchain software upgrade after the old and new protocol caused by new and old nodes of the new block recognition of a disagreement, soft fork generally does not produce a permanent fork chain, and the hard fork will produce t
