The Truth About Blockchain


Blockchain: distributed transactions that will radically change the world. Ben van Lier. The American mathematician and A. Turing Award winner Leslie Lamport is one of the founding fathers of distributed computing and distributed algorithms. Without the trailblazing by this founding father of distributed computing, today's blockchain technology hype would have been unthinkable.

Distributed computing A key requirement in the development of distributed computing is that a system made up of distributed processes has to be able to keep functioning, even when one or several of its components have ceased to reliably contribute to the functioning of the system as a whole. When it comes to reliability, Lamport is unequivocal when he says that a distributed system can only function reliably by using time as a fundamental part of its reliability [2].

As a whole, the system can only function reliably on a permanent basis when the majority of separate components of the system maintain consensus with respect to the functioning of the system as a whole. It is therefore key for a distributed system that all components involved keep a ledger of how and with whom they have performed transactions by exchanging and sharing data and information. All components must have access to information about transactions logged in the distributed ledgers, which are intended to provide an overall view of all approved transactions.

In Lamport's age, generating consensus between the various components of a system was a new and complex issue. In their article, Lamport, Shostak and Pease develop an algorithm that lays the foundation for reliable consensus between systems that are separated in terms of time and space. The essential idea in the solution they come up with is that to establish consensus there have to be at least three plus one components and mutual exchange of qualified messages between them.

In , Lamport added a protocol to this consensus principle that regulates the voting that is needed to achieve consensus between the various components within a system. This latter protocol, which is also known as the Paxos algorithm [4], addresses things such as how to handle the voting between the various components, how to record the results of the voting between the components in central and decentralised ledgers, and how to guarantee the consistency of recorded information.

Blockchain technology Without Lamport et al. The most widely known application of this technology so far is attributed to Satoshi Nakamoto [5]: Bitcoin. Blockchain's boom as an application for things such as value calculation, currency exchange, data storage in the cloud, or contracts, has received widespread attention in subsequent years. Blockchain technology's potential in developments such as the Internet of Things, mobile health care and advanced manufacturing has only been attracting increasing interest in the past two years.

Physical nodes in a network, such as computers, smartphones, sensors and devices such as smart TVs, fridges and cars can thus be interconnected through software and distributed algorithms that ensure consensus in transactions between these nodes. Distributed computing, Blockchain and the IoT Many agree that Bitcoin is but a first step towards numerous more applications in a wide range of sectors.

Silicon Valley's role in developing and shaping blockchain technology is considerable. It is therefore no surprise that Google, Microsoft and Amazon stand to gain a great deal from further development of the concept of distributed computing. Philips Healthcare has recently also announced that it is to research the potential uses of blockchain technology in exchanging and sharing data and information between medical applications.

Working closely together with parties such as Samsung, IBM is investing considerable time and money into making a blockchain possible for the Internet of Things. IBM expects the current growth of automated transactions to snowball on the back of the development of the Internet of Things and advanced manufacturing.

According to IBM, the exponential growth of the number of objects that are connected to the internet and share information through that connection calls for new paradigms such as the blockchain of distributed computing. The development of the theory behind this information technology has been ongoing for decades. Despite fundamental breakthroughs and the first advances in this field, the area of distributed computing and distributed algorithms is still one with numerous practical and theoretical issues.

Before we can start using this form of information technology globally in developments such as the Internet of Things, mobile health care and advanced manufacturing, we need better understanding of the possible development of such a new and technology-based ecosystem over time.

Databases and Blockchains, The Difference Is In Their Purpose And Design

Those of you who who fall in the early adapter camp are probably aware that it is some part of the certification system around the bitcoin mania. These include reference data maintenance in payment and settlement systems, trade finance, syndicated loans, and tracking provenance of agricultural products and commodities, their subsequent sale or use as financing collateral. He quotes one panelist, Caitlyn Long, chairman and president of Symbiont:. On the liability side, Long said DLT facilitates automatic execution of parametric insurance contracts. Still to come, he said, are new and innovative applications being developed to provide value and services not envisioned before DLT was developed. That will necessarily involve a learning curve, he said.

White paper – Distributed Ledger Technologies (DLT) and blockchain

Distributed file storage aims to support credible access to data on distributed nodes. There are some application scenarios, for example, data centers, peer-to-peer P2P storage systems, and storage in wireless networks. Nevertheless, among these applications, data blocks are inevitably replaced and inaccessible when there exists nodes failure. As a result, data integrity and credibility is absent. To overcome such a challenge, blockchain is explored to protect the distributed data. Through analysis and evaluation, we demonstrate that blockchain advocates data integrity and credibility for distributed file storage, as well as the application of blockchain technology for distributed file storage. Distributed file storage contributes to storing data over the network by distributed storage nodes.

Having been involved in the design and delivery of lectures spanning from undergraduate courses to a masters in blockchain and DLT at the University of Malta UMmalta with students ranging from IT and Computer Science, Business, Finance, Economics, Management, and Law and Regulation, I have given such introductory lectures and talks many times over. The highlights and parts of lectures that I tend to keep fond memories of always involve interaction with students. However, when I started this talk little did I know that I would receive a memento that will outlive my often volatile memory. During the talk an attendee put, what is for me, a masterpiece together — seen here. The drawing was passed on via Thy Diep Ta, the upbeat organiser.

On the Exploitation of Blockchain for Distributed File Storage

What is it? Distributed ledger technologies DLT like Blockchain are a secure way of conducting and recording transfers of digital assets without the need for a central authority. It is "distributed" because multiple participants in a computer network individuals, businesses, etc. New transactions are added in a manner that is cryptographically secured, permanent, and visible to all participants in near real time. Figure 1.


Blockchain - Distributed Ledger Technology: a stitch in time

Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain. Blockchain is a type of DLT in which transactions are recorded with an immutable cryptographic signature called a hash. This means if one block in one chain was changed, it would be immediately apparent it had been tampered with. If hackers wanted to corrupt a blockchain system, they would have to change every block in the chain, across all of the distributed versions of the chain. Blockchains such as Bitcoin and Ethereum are constantly and continually growing as blocks are being added to the chain, which significantly adds to the security of the ledger.

Blockchain is a form of distributed ledger technology. While it has grown in prominence, its full potential and.

Distributed ledgers are totally transparent, secure and irrevocable. Over time, you automatically generate an immutable audit trail. The obvious applications of blockchain are in financial services but the potential use cases are unlimited.


Are blockchain and distributed ledger technology the same? This is a common misconception that many people have. We are living in a digital age of sound bites and buzzwords. An age where even complex technological solutions are reduced to five words or less. As a result, we are witnessing a rise in cunning businesses attempting to piggyback the so-called crypto boom. Predictably, using buzzwords such as blockchain technology to attract investment will only deliver short-term gains.
