1. How does blockchain enable digital provenance?
Blockchain is like a digital stone, in that you can only add information to it. Erasing information is possible through the use of excessive force, but this is only achievable through controlling the majority of the nodes in the network. The more decentralised a network is, the harder it is for any one node in that network to challenge the consensus of the majority.
The bitcoin blockchain, for example, is a public ledger, where all transactions are traced, tracked, and potentially audited in real time, whether the data is encrypted or not. This allows users of the network to monitor the lineage of transactions relevant to the integrity of their business practices.
‘Don’t trust - verify’ is a common slogan in the crypto and blockchain community, wherein the mathematics built into the code is used to validate and confirm transactions on the blockchain. This scientific approach to verification facilitates digital provenance, making blockchain an ideal solution for businesses looking to improve the strength and sustainability of their supply chains.
2. Why doesn’t a normal database bring the same provenance?
Transactions and accounting are separate when using a traditional database - this creates ample room for bad actors to falsify or manipulate the data maliciously, or to serve self-interest.
Blockchain on the other hand, combines accounting and transactions into a single layer of the protocol, adding security to the network against attacks upon the integrity of the data and infrastructure contained within it, as well as circumventing the need for potentially corruptible human auditors.
3. Why is digital provenance such a great benefit to many businesses?
Blockchain extends beyond just cryptocurrency use cases. For example, OriginTrail is a specific company focused on providing provenance to their customers with blockchain technology, enabling supply chains to work together in a collaborative capacity through the automated exchange of traceable data in industries that include farming, fashion, and railway maintenance.
Blockchain is trustless and transparent by design - this is in direct contrast to how supply chains are conventionally run, in that manufactures and producers have to trust that their suppliers are being honest about the sources, quality, and ethical standards kept to with regards to their goods.
There is historically an opaqueness to this information, making it hard to establish the authenticity of claims made by companies concerning the items they sell. The transparency of blockchain technology gives companies confidence and assurance that they are able to reliably produce their wares with efficiency, consistency, and peace of mind.
