What Is Blockchain? The ‘Transformative’ Technology Behind Bitcoin, Explained
Download Charter document. Trust is a key requirement of the modern-day digital economy. In most current applications, trust is delegated out to a third-party who acts as a type of Trust Authority. This provides a degree of assurance to participating applications because they can verify information through the Trust Authority. Dependency on a centralized trust authority however carries some risk, should the centralized trust authority become compromised and suddenly become unavailable.
To address this risk, a new trust paradigm based on Distributed Ledgers has recently emerged. Distributed Ledgers are collections of replicated, shared and synchronized digital records that are stored across multiple sites that are geographically spread. An example of a DLT is Blockchain, which is a digital ledger of records arranged into linked chunks of data called blocks. The blocks are linked together through a hashing function that provides cryptographic validation on those records.
This charter defines the role of the DWG within the OGC, Blockchain and Distributed Ledger Technologies communities and allows for an open forum for the discussion and presentation of interoperability requirements, use cases, pilots, and implementations of OGC standards in this domain. At present, there are several DLT services and networks available.
There is however no standard for how those DLT should encode geospatial information such as locations, coordinates and coordinate reference systems. The various DLT have therefore implemented ad-hoc geo encoding approaches. This situation is likely to lead to a problem of limited interoperability between information held in different DLT networks.
Limited interoperability typically has the effect of higher costs for users because of limited options for data exchange. Furthermore, the risk of information loss increases when there is limited interoperability between systems.
By far, the most widely cited application of blockchain technology is in the finance sector where it can be used as a cryptocurrency as shown by Bitcoin and Ethereum. However, other application areas are gaining popularity too, demonstrating the utility of blockchain in non-financial sectors. Blockchain has been used in a variety of applications, for example cryptocurrencies, land registration, and justice. In each of these application areas, location can play a key role.
For example, the location of transactions can determine what taxes apply, the location of the boundary of a property forms the basis of its registration, and the location where evidence is discovered in a crime scene can have an impact on judicial proceedings. Recognizing the role that location can play in applications of blockchain, the OGC initiated a review of DLT and blockchain.
The review was initiated within the OGC Technology Trends activity, which has been set up to continuously provide analysis of technology trends and advise on their potential impact of current and future OGC standards.
The discussion paper has identified case studies of blockchain implementation in the following geospatial-related areas:. The discussion paper also identified related standardization initiatives by the following organizations:. Although this group will not be the platform for creating new standards, it will be the platform to discuss and understand any issues, concerns, or barriers to interoperability to ensure that geospatial data and other forms of location-referenced information can be used effectively within the wider Blockchain and DLT communities.
It is being chartered by the following members and individuals with extensive education and experience in blockchain, distributed ledger technologies and OGC web services security issues, namely:.
Membership will be open to those with an interest in blockchain and wider DLT. Active membership is defined by regular member contributions of material or participation in DWG meetings and discussions. This DWG is being established to address geospatial interoperability challenges within the blockchain and wider DLT communities. The group will facilitate discussion of the requirements that define different exchange methods, encodings in blockchain records and architectures to ensure that location-referenced information that is based on open standards can also be used within blockchain and other DLT.
Initial activities will include:. Define any areas for standardization and create necessary Standards Working Groups to address the gaps in the OGC standards baseline.
Explore the potential for an interoperability pilots and testbeds that help define geospatial architectures that benefit from Blockchain and other DLT. Some of the issues that need to be addressed by the DWG include the encoding of geospatial information and metadata in DLT.
Without improvements to standardization in this area of DLT, the problem of limited interoperability will become an obstacle for growth. Without user education activities that reach the wider DLT community, there is a risk of slow uptake of geospatial standards within that community.
Understand implementation barriers for the broader use of geospatial data in distributed ledger technologies and document them in a way that can guide future project work. Identify interfaces and information encodings that complement the existing OGC standards, but are tailored to the requirements of the DLT community. Identify use cases where efforts to streamline data transfer and exchange requirements result in a net gain for the community by broadening the usefulness of geospatial data in Blockchain and other DLT.
Monitor the practices of domains and DWGs with similar objectives and problem sets, and recognize potential for sharing and collaboration between domains and DWGs. The Blockchain and DLT DWG will concern itself with technology issues related to blockchain and other DLT so that geospatial data and services can be more effectively represented in DLT, and the means by which those issues are appropriately factored into the OGC standards development process.
The mission of the Blockchain and Distributed Ledger Technologies Domain Working Group is to enable the OGC as a community to improve its understanding of distributed ledger technologies, their use cases, applications and opportunities for geospatial standardization; review and assess the impact of distributed ledger technologies on the OGC standards baseline.
The role of the Blockchain and Distributed Ledger Technologies Domain Working Group is to serve as a forum within OGC for distributed ledger technologies issues; to present, refine and focus interoperability-related issues to the Technical Committee; and to serve where appropriate as a liaison to other relevant industry, government, independent, research, and standards development organizations active within the distributed ledger technologies domain.

Almost all of them are wrong because they start from a false premise. There is no universal definition of a blockchain, and there is widespread disagreement over which qualities are essential in order to call something a blockchain. The Bitcoin system is considered the first blockchain — the epiphany that launched the blockchain industry that proponents say will revolutionize money, government, and beyond.

What is blockchain? Blocks, distributed ledgers and nodes explained in simple terms
They will not be evidenced by physical certificates or notes, recorded in book-entry system of the type typically used by issuers and transfer agents today, traded through a traditional securities exchange or cleared through an established clearing system. Interest in using blockchain technology to increase the efficiency of, and reduce costs and risks associated with, securities transactions has continued to grow rapidly in recent months. For example, Nasdaq Private Market, LLC recently unveiled a platform to allow trading in private company securities using blockchain technology. Many proposals to use the blockchain for securities transactions remain under development and continue to evolve.
What is Blockchain?
Blockchain is one type of distributed ledger: distributed ledgers use independent computers — referred to as nodes — to record, share and synchronize transactions, instead of keeping data centralized as is the case with a traditional ledger. The Blockchain organizes data into blocks, which are chained together in an append-only mode. It has the capability to move any kind of data swiftly and securely and, at the same time, make a record of that change, movement, or transaction instantly available, in a trusted and immutable manner, to the participants in a Blockchain network. In terms of governance, Blockchain technology is decentralized. There is, however, an operator function that sets the rules for everyone in the network, along with regulators and government agencies.
Blockchains: Recent Applications of Distributed Ledger Technology in the Banking Industry
Distributed Ledger Technologies DLT such as Blockchain are a concept known to many people as the technology behind the cryptocurrency Bitcoin. But their potential to redefine how we do business and also redesign our business structures remains unclear to many. DLT are decentralized, digitally managed ledgers. By the capacity to distribute information with a high level of transparency and security, DLT have really refined the internet. Distributed Ledgers are basically a collaboration model which is based on an old idea: the cooperative system. DLT transfer this system into the digital world.

RELATED VIDEO: Blockchain vs Distributed LedgerBlockchain is one type of a distributed ledger. Distributed ledgers use independent computers referred to as nodes to record, share and synchronize transactions in their respective electronic ledgers instead of keeping data centralized as in a traditional ledger. Blockchain organizes data into blocks, which are chained together in an append only mode. Distributed ledger technology DLT could fundamentally change the financial sector, making it more efficient, resilient and reliable.
Blockchain technology is often used as a synonym of distributed ledger technology DLT although both are not the same. A blockchain uses several technologies, including distributed ledger technology, to enable blockchain applications. Blockchain technology is a form of distributed ledger technology. A blockchain is a distributed and immutable ledger to transfer ownership, record transactions, track assets, and ensure transparency, security, trust and value exchanges in various types of transactions with digital assets. Distributed ledger technology DLT revolves around an encoded and distributed database serving as a ledger whereby records regarding transactions are stored. At the core DLT is an innovative database approach with a data model whereby cryptography is utilized in each transaction update and verification become possible across the specific blockchain network, depending on its goal and stakeholders. A look at distributed ledger technology in practice and beyond cryptocurrencies — how blockchains and DLT work, industries, applications, evolutions, networks and the business reality.
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.
