  1. Normal database is efficient, fast, easier and cheaper to use than a blockchain database. If you don’t need the security, immutability, transparency and other benefits of a block chain, then use a normal database.

  2. It would be very inefficient, costly, difficult to build, difficult to maintain, difficult to integrate, etc.

  3. Because of transparency and security.

  1. Speed plus not shelling out the time and money to build a custom solution that will work with your existing system.
  2. Expense, time invested creating the solution, extra infrastructure needed to manage peers and certificates.
  3. The more writers the less possibility of fraud or mistakes.

  1. a normal database is cheaper as all developers know how to use
  2. if we dont need blockchain and are using it anyway, its more expensive because it needs specific knowledge, it takes much more time to create the blockchain project.
  3. to remove an unknown middleman and to provide transparency

  1. What are the benefits of using a normal database instead of a blockchain?
    Much easier to deploy. No consensus mechanism so Tx’s are processed faster. Centralized control over data.
  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    Higher overhead costs of setup. Slower Tx processing.
  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    Because if not you are simply just having a single user write to multiple servers which increases processing and involves higher costs to maintain the infrastructure of a blockchain.

  1. Cheaper, less time consummed to get to basiaclly the result you are looking for. Easier to get it fix or updated

  2. Need specialist to get the job done, extra cost, and probably lost your job because you did not adjust to the real needs of your client :slight_smile:

  3. only one writer get to the conclusion of not trusted. You need more node then one to get concensus,
    therefore get a trusted blockchain

Reading Assignment: Blockchain Decision Tree

  1. What are the benefits of using a normal database instead of a blockchain?
    It’s easier and cheaper to build.
    It’s easier to find the knowledge and experience to run it.
    It would also give more control over unified data interests.

  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    Takes to much time and unnecessary expenses out of company’s budget in building the blockchain, due to lack of experience.
    It can also remove the invisibility and management of harmonized data of the company’s interests to others outside the organization.

  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    Otherwise there would just be one dictator over the data with full control of what will be written to it, instead of a consensus would be needed with more than 1 writer.

  1. A normal database is centralized under the control of the sole user.

  2. The blockchain is all about decentralized control of the network and its activity, If the user uses the blockchain as another database its a waste of energy.

  3. A block chain needs to be distributed in order for it to be relevant, if its composed of 1 writer then its just a program running on a database that does not have the benefit of being neither, retributed, decentralized or trustless.

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

    They are faster, more efficient, and easier to set up.

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

    Its going to cost more than setting up a traditional database and your database will not be as efficient.

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

    When you only have 1 writer you only need to trust 1 person. Blockchain help establish a trustless environment when there are multiple are writers.

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

  • Easier and cheaper to build
  • Competency & Skill is easier to find vs. lack of experience
  • More resources are available

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

  • Expensive
  • Wasted time

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

Avoids unnecessary consequences. One solo writer defeats the blockchain consensus philosophy

  1. A normal database is cheaper, more efficient, and easier to implement.
  2. Higher costs, less efficiency
  3. Only one writer means that there is no trust required between parties. Blockchain makes a transaction trustless

What are the benefits of using a normal database instead of a blockchain?
Many programing languages available, Databases are cheaper than developing a blockchain solution. More available talent to work on databases rather than Blockchain
What do you think the consequences would be of using a blockchain when you in reality don’t need one? And it would be a chore to maintain and integrate with other databases.
The economic cost will be high and the time wasted will be a killer too.
Why should there be more than 1 writer to a database in order to justify a blockchain?
needs to have at least 2 users or more write to gain trust.

  1. Efficiency, higher speed of transaction processing, cost effective, easier to integrate and modify information, privacy, competency and skills easier to find.

  2. Higher costs, slower speed of transaction processing, unnecessary use of resources, worse user interface, more programming needed, harder to find competency and skills to maintain and develop the network further.

  3. If there is only one writer that one writer will always be a trusted party so there is no need to implement a trustless system which would not bring the benefits a blockchain system offers but yes the cons.

Normal database is efficient, fast, easier and cheaper to use than a blockchain database. If you don’t need the security, immutability, transparency and other benefits of a block chain, then use a normal database.

  • Expensive
  • Time intensive

. In this regard the transparency of a blockchain is essential.

  1. Faster, more efficient, cheaper
  2. Unnecessary expense, slow to develop, not flexible
  3. Because if there is only 1 writer, everybody knows who has entered the information; the 1 person. Nobody has to wonder who changed or input what. With 1 authority-person, they hold the trust of the company and the power. If money goes missing, everybody knows it was the 1 person.

= faster, cheaper, more easy to find developer and administrators

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

= higher costs, slow transaction, lot of senseless work for changes, inefficients

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

= because if you only have one writer and he trust himself a blockchain is senseless.

  1. The benefits of using a normal database vs a blockchian is the speed of transactions, query speed and privacy of data.

  2. It is more expensive, needs more resources, costs more development effort.

  3. There should be more than 1 writer to a database for transparency and trustless system.

1/ Database are far more efficient in CRUD functionalities; Blockchain are good at preserving data integrity, and immutability in transactions sequencing

2/ losing lot of money, as building a team with experienced people in blockchain project is presently very expensive (rarity of experience)

3/ with 2 or more writers, not unified by a top supervisor (the orderer), there will be current conflicts about: which (whom coming from?) is the accurate data to be inserted in blockchain?
