1.What are the benefits of using a normal database instead of a blockchain?
It is cheaper and fast. And also it is easy to maintain due to the skills required.

2.What do you think the consequences would be of using a blockchain when you in reality don’t need one?
It is going to take unnecessary time and money.

3.Why should there be more than 1 writer to a database in order to justify a blockchain?
If you only allow one writer, it is centralized.

  1. Privacy of data, cheaper to implement infraestructure, fast, easier to find skills to develop it.

  2. Lost of time in order to create a complex infraestruture, expensive, unefficient, lack of specialist on Blockchain area.

  3. In order to get a consensus, more then 1 writer is a must. With just 1 writer doesnt have sense to create a descentralized infraestructure.

  1. Tech readily available and inexpensive in comparison to a Blockchain. Recruiting staff is easier and less expensive with a lot of knowledge if you use a well known DB/RDBMS, Standard DBs tick a lot of boxes.

  2. expense, possible loss of job, bad press for Blockchains, processes made more complicated unnecessarily

3)more than one writer could play into the hands of a Blockchain due to it’s security features and immutability.

  1. What are the benefits of using a normal database instead of a blockchain?
    => When no shared write access is required, writers known + trusted + unified interests, want/need to use trusted 3th parties
  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    => It is more expensive, needs more resources, costs more development effort.
  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    => With more writers its important to trust the input, so transparancy of a blockchain database is essetial.

  1. It’s centralised, secure and cheap to implement and manage
  2. It would be a costly exercise to implement and maintain, more “admin” and headaches (having to give nodes permissions to write to the database etc)
  3. Because it’s a system of decentralised consensus across a network of many nodes

1.What are the benefits of using a normal database instead of a blockchain?

If the need is to only have a database without shared writing access, then sticking to a traditional database would be wise. Same thing if there’s a need of a database with shared writing access, where network writers are known and trusted, and have unified interests.

2.What do you think the consequences would be of using a blockchain when you in reality don’t need one?

Depending on the type of blockchain used, there could be a risk of confidentiality issues that could hurt a business and even problems complying with rules and regulations businesses have to follow. Also, restructuring the existing IT-infrastructure would be expensive and time consuming.

3.Why should there be more than 1 writer to a database in order to justify a blockchain?

For consensus and security reasons. Consensus helps verify authenticity of transactions and avoid double spending. One single writer has no other parties to trust in the database and therefore no need of consensus.

  1. Open, easy and no constraints
  2. Adding constraints and complication that are no needed
  3. The whole purpose is to have some activity, transactions ans security, one person does not justify investing in a blockchain.

  1. A normal database instead of blockchain offers improved throughput and performance and a lower operating cost.

2/ Using a blockchain when it is not required would cause more expensive development and operation and lower performance and throughput.

  1. If only one party is writing to a database then their are no trust issues to justify the use and expense of using a blockchain soltuion.

  1. Normal databases are functional, simple and cheap. A family ran pizza shop would be an example of one who prefers it that way. They wouldn’t see problems that would involve spending more money incorporating blockchain technology.
  2. Adding higher costs, while making simple efficient native ways complex.
  3. To remove the problem of trusting middle men, the double spending problem, no consensus needed.

Waste of resources, time and money.
3. Why should there be more than 1 writer to a database in order to justify a blockchain?
Backup, backup, backup…plus at minimum you need show transparency and verification of the blocks.

  1. Its more efficient because it doesn’t require high security like blockchain.
    It’s easier to implement since it’s already a common thing compared to blockchain and has a lot of resources

  2. There will be a waste of time, energy, funds, in implementing that since blockchain is a relatively new technology and still more expensive than usual database system

  3. When there is 1 writer which we know and trust, there is no point of using blockchain since everything from him is already true. MOre than 1 writer is required to provide consensus in the blockchain

Do you even need blockchain?

  1. What are the benefits of using a normal database instead of a blockchain?
    Databases are less complicated to implement and maintain. They also have better performance.

  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    It would be a waste of time and money and might unnecessarily introduce points of potential failure.

  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    Expending resources to reach consensus does only make sense if there are at least 2 parties that can disagree on what is true.

  1. What are the benefits of using a normal database instead of a blockchain?
    Easier to set up, cheaper, faster

  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    High costs, not flexible in terms of changes

  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    Otherwise a BC would not make sense at all because there wouldn’t be other users we would have to trust.

What are the benefits of using a normal database instead of a blockchain?
A normal database allows edits, efficient, fast, cheaper than a blockchain databse. It is much easier to learn how to operate a normal database and there’s plenty of reference online.
*** What do you think the consequences would be of using a blockchain when you in reality don’t need one?**
Expensive and much harder to respond to changes required.
*** Why should there be more than 1 writer to a database in order to justify a blockchain?**
Transparency and security issues. If there is only one writer his/her power won’t be contested and he/she may not be using the Blockchain to its maximum productivity.

  1. It is faster, atm better to maintain as you find personal easier, cheaper in general
  2. Depending on the use case, but for sure more expensive, slower, could harm your growth in your business
  3. If you have only one there is no need for a blockchain where multiple can participate. Especially if the writer is trustworthy.

    faster, cheaper, efficient
  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    higher cost, higher maintenance, time intensive
  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    Otherwise it is not decentraliced, so it is centralized only with 1 writer

  1. Normal databases are more efficient, faster and cheaper than a blockchain. If you trust all parties.
  2. they have higher cost, are harder to change functionality, rules, speed and etc.
  3. If only one writer you would have to trust it as a third party, the point of the blockchain is NOT to trust but VERIFY.

  1. Cheaper (easier to find people with the skillset unlike blockchain), faster, Easy to query, more privacy and data are saved as key-value pair.

  2. More cost for the company, reduce speed and potential confusion within the company.

  3. Consensus.
