As  Blockchain  Blockchain Blockchain comprises a digital network of blocks with a comprehensive ledger of transactions made in a cryptocurrency such as Bitcoin or other altcoins.One of the signature features of blockchain is that it is maintained across more than one computer. The ledger can be public or private (permissioned.) In this sense, blockchain is immune to the manipulation of data making it not only open but verifiable. Because a blockchain is stored across a network of computers, it is very difficult to tamper with. The Evolution of BlockchainBlockchain was originally invented by an individual or group of people under the name of Satoshi Nakamoto in 2008. The purpose of blockchain was originally to serve as the public transaction ledger of Bitcoin, the world’s first cryptocurrency.In particular, bundles of transaction data, called “blocks”, are added to the ledger in a chronological fashion, forming a “chain.” These blocks include things like date, time, dollar amount, and (in some cases) the public addresses of the sender and the receiver.The computers responsible for upholding a blockchain network are called “nodes.” These nodes carry out the duties necessary to confirm the transactions and add them to the ledger. In exchange for their work, the nodes receive rewards in the form of crypto tokens.By storing data via a peer-to-peer network (P2P), blockchain controls for a wide range of risks that are traditionally inherent with data being held centrally.Of note, P2P blockchain networks lack centralized points of vulnerability. Consequently, hackers cannot exploit these networks via normalized means nor does the network possess a central failure point.In order to hack or alter a blockchain’s ledger, more than half of the nodes must be compromised. Looking ahead, blockchain technology is an area of extensive research across multiple industries, including financial services and payments, among others.

Read this Term (SZSE) has released a new index tracking the performance of 50 companies working in the sector.

Dubbed Blockchain 50 Index, investors can invest in the index to get exposure to firms working on blockchain technology.

According to the official announcement published on Wednesday, the index is tracking the performance of major companies, including Ping An Bank, S.F. Holding, Visual China Group, and Midea Group.

The index was jointly released by the SZSE and its subsidiary Shenzhen Securities Information. The announcement also detailed that the chosen companies are involved in the upper, middle, and lower streams of the blockchain industry, including hardware equipment, technology and services, and other applications.

The 50 companies for the index were picked based on their average daily market value during the latest six-month period. Moreover, the index is capitalization-weighted, meaning the shares have been included based on the total market capitalization of the outstanding shares.

The Hype over blockchain in China

The index was introduced amid the speech by Chinese President Xi Jinping, in which he boosted the nascent technology and urged the country to capitalize on it.

Many major private players in the country also jumped in the development of blockchain-based products, including technology giants like Tencent.

Though this is the first such index on the Chinese stock exchange, its United States counterpart NASDAQ has been tracking performances of crypto and blockchain stocks for a long time. In September, the New York-based exchange launched an index to track the much-hyped decentralized finance sector, which includes firms like Augur, MakerDAO, Amoveo, and 0x.

Meanwhile, officials of the Chinese foreign exchange regulator recently revealed that the agency is planning to expand the scope of its blockchain-based cross-border financing platform.
