Ans.1) First…block-chain technology achieves digital provenance by receiving computational and mathematical solved transaction data from the supply chain, storing it in a block and then transmitting, broadcasting or distributing those identical stored records across a vast network of computers.
Second, these transactions become, what’s known as permanently decentralised immutable records with trace-ability. How? By holding an exact copy record of transaction(s), validations, verification’s performed on one part of that network with time/date stamps. Those preceding transactions now become a direct reference point used to validate and verify any future transactions made, which become the new superseded transaction data records further down the chain of newly created blocks of permanently stored data. Any later block additional adjustments, made through transaction, are tested, matched to previous records, proven, validated, verified and adjusted, time stamped and only placed inside the new data storage block after being accepted as authentic against the consensus of the majority of records held throughout the decentralised distributed network. These newly accepted and authenticated records are then broadcast as an update/addition to all decentralised computing systems maintaining the network providing accuracy and reliability.
Third, now exclusively operating through executable coded rules and mathematical computations (block-chain), requirement no longer exists needing any central control systems of governance, trusted third-party or any intermediary body, such as a company, organisation, government agency or banking institution to verify ledger entries, exchanges and transfers of value. Block-chain removes the need for these inefficiencies providing solutions of not needing centralised trust, based on programmable code operating in exacting accordance to required coded tasks, namely, validation, verification and authenticity of transaction data.
Fourth, block-chain is publicly open source code technology, fully viewable and accessible by everyone. This is known as transparency, a public ledger of every transaction ever performed in the block-chain.
Finally, block-chain not only has all these above-mentioned benefits and attractive features, but is furnished with the highest level of security being full military grade encryption which provides the greatest level of defence for protecting the transaction data stored within blocks upon the distributed decentralised network.
Ans.2) Primarily, normal database operate from a centralised located system. These systems are fraught with susceptibility to hacks, (past) data manipulation (internal/external), loss of sensitive information and errors associated with human interactions. These databases are closed systems and cannot be viewed by the public. These systems can be accessed only by administrators, who may decide to modify data for their own sordid gain. Records stored within their appropriate index of the database also require further accounting validations and verification’s to be cross-checked and performed by internal/external auditory bodies. In a normal central database, their exists a disconnect between transactions captured and recorded, and the layers of records of accounting. They also become large silo’s of data and a honeypot for attacks by bad actors wanting to cash-in.
Ans.3) It offers businesses end to end solutions for recording immutable time-stamped data transaction of every facade of their business supply chain. It offers full disclosure or transparency to consumers. It quickly identifies recalls and isolates any particular item within the supply-chain, that should be found in question. Allows consumers to check and verify product procurement on the public ledgered block-chain, against the shop delivered labelled data records. It removes the need for human verification, it becomes the autonomous trust-less, supply efficiency model. It builds and provides confidence and trust in efficient execution of programmed set standards.
