Colt Technology Services, a multinational telecommunications firm, and Pacific Century CyberWorks (PCCW) Global have joined forces with  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  Startup  Startup A company operating within its first stage of investing is known as a startup. While startups may give the impression that the company must be new, that is not always the case.Many companies can have this designation after nearly three years of existence. Typically, a company exits the startup status after a period between 3 to 5 years or after successful funding rounds where capital is acquired. Startups tend to derive out of the belief that there is a demand for a service or product which is created by at least one or more entrepreneurs. These seek capital as a means to bypass a limited availability of capital and combat high costs. This is why startups seek funding from funding rounds, crowdfunding, venture capitalists, financial institutions, or other sources. What Makes Startups Successful?Given the fact that most startups fail, the first three years of a startup are critical which is why startup founders require capital for talent acquisition, creating effective business models and plans.In parallel it is important to provide proof-of-concept for the long-term through an established user base and consistent revenue streams. Many startups use seed funding, which occurs during the first stage of funding rounds, where fundraised capital is used to conduct market research and product or service development.Sometimes, startups go through an acquisition process, where they merge larger companies competing in a similar industry. Companies that generate less than $20 million annually, possess less than 80 employees, and are primarily controlled by the founding entrepreneur(s) are generally classified as startups. Today, some of the world’s most successful companies started as startups, such as Facebook, Uber, and SpaceX to name a few.

Read this Term Clear to develop a proof of concept (PoC) involving blockchain technology.

According to MondoVisione, the PoC demonstrated that blockchain can be used to reduce the amount of time needed for inter-carrier voice minute settlements from hundreds of hours to just a few minutes. The PoC involved the implementation of a bilateral blockchain that recorded and reported transactions to a public blockchain. Smart contracts were used to resolve disputes, record settlement transactions, and rate call detail records.

The PoC was demonstrated on two separate occasions, the first of which took place at the Pacific Telecommunications Council annual conference earlier this year. When tested, the PoC developed by these three firms resulted in tens of thousands of call records being analyzed and settled within the space of a few minutes.

If the transactions were processed according to current industry practices, the operation would have taken weeks or even months to complete.

Indeed, “current industry practices” involve these types of settlements being carried out using manual transactions. This is particularly surprising because of the financial importance of the settlements to phone carrier companies and the high costs associated with manual work.

Speed and Security

In addition to making the process much speedier, using blockchain to settle these kinds of transactions makes the process more secure. This is especially important when you consider the sensitive nature of the information being exchanged in this industry.

The immutable nature of blockchain technology is also particularly well-suited to these kinds of transactions because, as MondoVisione reported, the industry is "rife" with fraud. Additionally, "dispute resolution can be lengthy and complex." The application of blockchain technology will ensure clarity in record-keeping.

“It is exciting for any business to create something that has the power to truly innovate how an entire industry operates. This PoC marks the beginning of how blockchain is set to revolutionize the telecom sector,” said Gal Hochberg, Chief Executive Officer of Clear.
