Homework on Provenance - Questions

  1. Blockchains are logs of record that can be replayed recalling every state the blockchain had.
  2. Traditional relationship databases tend to store the data normalized, losing on that process part of the historic data.
  3. Digital provenance expands the data sources businesses have from their supply chains

How does blockchain enable digital provenance?

Since the blockchain is an immutable ledger that is decentralized makes changing any info on the blockchain very hard, in other words, the informattion that is originally written on the blockchain cannot be changed or tampered with.

Why doesn’t a normal database bring the same provenance?

Because it has a central authority, and the central authority has the possibility to change the information. In other words it is not immutable and and is prone to corruption. This requires thatthe central authority allocates administrators that need to be trusted.

Why is digital provenance such a great benefit to many businesses?

Because its provides the opportunity to do live auditing and the it can remove the overhead of the accounting department or accounting firm or accounter. It also has the ability to provide it in a transparent manner if so needed, live and in real time. The information and benefits provided by digital provenance is highly reliable and is verified at the point of entry and cannot be changed after that. The possibility to include the information and the transaction into one is also a great time saver to anyone running a business and minimizes discrepancies

blockchain enhances provenance by tracking goods on a trustless system. You can’t change the info, just add to it, so it’s harder for businesses to cheat or be fraudulent.

Question 2
Normal data bases are not trustless. You have to rely on humans to be honest. Things put on the blockchain for tracking cannot be changed, just added to.
Question 3
It makes businesses more efficient, thus more profitable. All transactions for tracking, finance, and accounting are in one area.

  1. It is provided by the blockchain by veryfication of all the nodes off the system.
    Also you are not able to remove information from the system.
  2. Because it is centralized and the central entity can change the the information however
    they want.
  3. Because it’s a trustless system built on veryfication. You can track all the information
    from the start till the end.

  1. How does blockchain enable digital provenance?
    By keeping full copies of the entire history of transactions distributed across a decentralized network.
  2. Why doesn’t a normal database bring the same provenance?
    A normal database is centralized which is subject to error and manipulation.
  3. Why is digital provenance such a great benefit to many businesses?
    It enables tracking on transactions and supply chains that don’t require trust of a third party.

  1. Blockchain enables digital provenance by allowing users to input permanent data on a decentralized public ledger. A network of computers verifies the transaction before it is added to the public ledger. This verification allows trust to be established without the need of a centralized agent.

  2. A normal database doesn’t provide the same provenance because it they require a central agent to verify the data.

  3. It reduces the time to verify information, and reduces the risk of relying upon a central agent. If the central agent is taken down, the data is at risk of being compromised or removed.

Question: How would a blockchain handle erroneous data? Say there is a supply chain for pork manufacturing. (the chain consists of the farmer, the slaughterer, the meatpacker, the shipping company, the grocery store). What if the farmer accidently input the wrong weight of the pig, or the wrong type of feed? How would the blockchain know that was erroneous data?

How does blockchain enable digital provenance?
Information is added to the blockchain, no one is able to delete it and everybody is able to track the transactions.
So for every information stored in the blockchain, the provenance can be verified.

Why doesn’t a normal database bring the same provenance?
Normal databases are controlled by a central instance and therefore can be manipulated.
You have to trust the instance that the information is valid and you have no way to verify that.

Why is digital provenance such a great benefit to many businesses?
It is such a great benefit because the paradigm of central instances controlling information is changed.
Therefore, transparency can be brought to any existing businesss where centralized ledgers are used nowadays (e.g. Banking, Supply Chain).

Bitcoin is used for financial transactions. Things like supply chains are not part of it. There are other companies that tackle these problems, one of them being OriginTrail. I suggest you contact them and ask how they solve this issue. :slight_smile:

1.Blockchain is a public ledger that allows you to track financial and/or non-financial data in real-time, without the risk of it being corrupted.
2.Because it’s either publicly unavailable or it’s inaccurate due to human error.
3.Firstly it makes the process of audit more accurate and efficient. It also holds a defensive value - in case that false allegations are made towards the company.

How does blockchain enable digital provenance?

A blockchain-based provenance system could prevent against manipulation by providing a complete, transparent audit trail of the collectibles, that is collected, processed, and accessed. Any modifications made to the collectibles would require at least 51% consensus from stakeholders and would be visible to everyone, ensuring high data quality and preventing fraudulent attempts.

Why doesn’t a normal database bring the same provenance?

Blockchains offer a number of fundamental advantages compared to centralized ledgers — immutability, improved security, greater reliability, transparency, privacy, and efficiency.

Immutabillity : this means that data stored in blockchains cannot be modified, appended or erased unless 51% of nodes agree to the changes.

Security & Reliability : there are no individual points of failure. Blockchains are designed to be both resilient to attacks and self-healing. If a node in a blockchain network goes offline or becomes unstable, the remainder of connected nodes continue working to make the network available, and no data is lost or compromised.

Why is digital provenance such a great benefit to many businesses?

Because it allows you to “showing your work” in a database. That information can be trusted for validation and auditing.

Blockchain combines the accounting/transaction layers, to create a public immutable distributed ledger, verified by all the other network nodes.

A normal database can be modified by whoever created it, it can also be made not public. Makes it very hard to verify or trust information.

It will allow businesses to verify information in house or on the network at any time. Information is power.

  1. How does blockchain enable digital provenance?
    As you explain, the blockchain is a book that we can only add information never removed, this makes the process reliable with transparency and traceability.
  2. Why doesn’t a normal database bring the same provenance?
    Because the normal database you can edit, delete or lose information making the process unreliable and is the opposite of blockchain to where the process is transparent and can always be verified instead of trusting
  3. Why is digital provenance such a great benefit to many businesses?
    The provenance make any process be able of be verified instead of the need for trust.

  1. By keeping track of all transactions. And keeping them on a public ledger, for anyone to audit.

  2. Because it is decentralised. So no one can change or tamper with the information in this database.

  3. The advantage for businesses is that you know where fe. ingredients or materials come from. Where they started, in what condition and so on. This makes that you can do trustless transactions.

  1. It enables digital provenance by eliminating the need to trust. It is decentralized from any government or authority and uses math to instantly verify transactions (real time auditing)
  2. Normal database is centralized and there we need to put trust in third parties such as governments to verify our transactions and this can lead to mistakes or fraud.
  3. Its a great benefit because it eliminates the need to trust because transactions, food ingredients etc… are instantly verifiable.
