Blockchain, or Distributed Ledger Technology (DLT), enabled Bitcoin, the first cryptocurrency. Since then, many new DLTs have come to market – built to mathematically deliver trust in an uncontrolled environment – where the distributed results and grouped consensus is derived to determine the integrity of the absolute result.
A Distributed Ledger is an append-only database technology in which every new block of information is encrypted with a part of the previous one, making the historical record of data unchangeable. This builds up into a chain, where if it were even possible to remove a link – this would be identified immediately.
As the name implies, the database is also distributed by nature. In contrast with other distributed technologies it does not spread the data over the network – instead all members keep a fully synchronised copy of the data – each ‘peer’ therefore being essential in determining the integrity of every new transaction. The result is that to break into the system, this would have to happen to all members at the exact same time.
Most Distributed Ledgers historically have been public in which any person or organisation can contribute compute power to the system. To incentivize these attributions, complex Proof mechanisms that require extra compute power have been put in place, such as Proof-of-Work (PoW) and Proof-of-Stake (PoS).
Public Distributed Ledgers also lack a certain minimal level of governance. This results in hard forks where sub-segments of the infrastructure get their own way – an unacceptable feature for adoption by Enterprise or Governmental customers.
A new type of high performance and high governance ledger has therefore been created for business – Enterprise Blockchains – removing these negative attributes and supported by some of the largest and most trusted technology brands.
Gospel Technology uses Private, Enterprise Blockchain frameworks that can be run on premises, on a shared infrastructure with partners or in a controlled public cloud environment, providing full control over the infrastructure management by the stakeholders of the ledger. The lack of unnecessary consensus mechanisms built in public DLTs increases the performance capabilities exponentially without impacting on the integrity and security guarantees built into the system.
Gospel LedgerBridge is the technology that allows data to be translated and copied onto the Gospel Cloud and underlying Blockchain. It is an application environment that includes the source data integration through API and the secure, encrypted connection to the Gospel LedgerNode, ensuring that data copied from centralised systems is absolutely secured as it is translated to transactions on ledger.
LedgerBridge also adds additional metadata to increase security and context. This enables the distributed data logic to be even more accurate when it comes to trusted consent driven transactions. Data such as location, identity and time are appended, therefore enabling analysis on transaction behaviour and filtering the data for consent based usage.
The technology therefore creates a link between multiple data sources such as generic databases (SAP, SQL Server), structured data files (.CSV or .PPTX), or regular unstructured data types (images, word processing, .PDF, .DWG, … )
LedgerBridge can be deployed as system, or indeed for industry specific applications, and for custom requirements an SDK can be provided for full configuration and API integration.
Gospel LedgerNode is the scale-out entity that holds the actual data and capacity. Each LedgerNode holds the world view, i.e. the current active data set versions and the full immutable history of real data versions, and consent rules. This LedgerNode also holds the Gospel core application and the underlying Enterprise Blockchain.
All actual data and configuration are stored on-chain and therefore the number of LedgerNodes can be increased to improve security and distribution. The Gospel Cloud service is based on a minimum of 5 LedgerNodes in each region. The current regions are North America, Europe and Asia-Pac. Nodes can be added or removed non-disruptively and the chaining of LedgerNodes creates extreme high availability where there is no single point of failure.
LedgerNode is platform, cloud and Blockchain agnostic allowing Gospel to deployed with extreme high availability. LedgerNode data replication and synchronisation is handled with an advanced consensus mechanism that goes far beyond traditional storage system replication. This makes ‘backup’ obsolete as Gospel ensures incorruptible replicas that are geographically dispersed- natively managed through the architecture.
Gospel TrustLink allows not only data ingest, but also egress to the data on the ledger. TrustLink holds the identity information and configuration to allow absolute trusted access to the data. It also ensures the identity of transactions in line with Distributed Data Logic.
TrustLink is also used for administration and user engagement with the system. Its encrypted signatures allow access to the membership services alongside multi-layer authentication.
Many security mechanisms are natively already built into Gospel including Public Key Infrastructure (PKI) and the fault tolerance consensus algorithms that together do not allow a system to be broken from within.
Gospel Cloud also adds an additional layer of security, as it in real time trends behaviour across the system. Transaction and consent is monitored to ensure the rules and access context are within expected norms of behaviour and activity.
The multi-platform web application (HTML5/Angular) allows a rich user experience with Gospel Cloud. Data owners can configure Gospel’s Distributed Data Logic for transparent and secure data usage. The web application allows secure desktop and mobile access through multi-layer authentication.
Gospel adds a rule based consent so the subject of the data can choose whether this data can be shared, with whom and for how long. This logic allows absolute trusted access to defined content for systems and people. It goes beyond permission based systems to define context and identity as part of consensual access.
Distributed Data Logic makes global security policies redundant as trust can defined at the point of transaction in a totally secure manner.
This method safeguards unlawful access of personal data when it resides on the ledger. Access can be requested, granted or denied, helping your company with your data compliancy standards.
Gospel RESTful API will make true end-to-end integration possible between different systems and applications. LedgerBridge and TrustLink securely translate structured and unstructured data into and out of the platform. This accelerates enterprise data integration with cloud services, essential in the age of digital transformation.
