• What are the benefits of using a normal database instead of a blockchain?
  • higher efficiency
  • lower costs
  • greater accessibility
  • easier development
• What do you think the consequences would be of using a blockchain when you in reality don’t need one?
  • critical misallocation of capital, therefore loss of potential profit
  • could lead to project’s comlete failure
  • could cause company to collapse
• Why should there be more than 1 writer to a database in order to justify a blockchain?
  • The whole point of a blockchain is to have trustless, decentralized consensus amongst multiple parties. If there is only one party in charge of writin data, then there is no need for a decentralized ledger

1.) What are the benefits of using a normal database instead of a blockchain?
Easier and cheaper to develop solutions.

2.) What do you think the consequences would be of using a blockchain when you in reality don’t need one?
It would waste a lot of time and money.

3.) Why should there be more than 1 writer to a database in order to justify a blockchain?
Because of transparency and security reasons.

[emiliano_sosa]

1. scalability, speed, effienciency, cheaper, easier to make changes to.
2. It could end up being costly and you might need to make upgrades or changes that wouldnt be possible to do.
3. For consensus and decentralization, you do not want to have only one person being able to do one function on a blockchain.

1. The benefits of using a normal database instead of a blockchain are that a “normal” database is faster and cheaper to implement. These are more efficient, and easier to deploy.
2. Using a blockchain when you in reality don’t need one would

• spend capital and time that would not have needed to be spent without increasing value to the organization
• over complicated the BD
• slow down production in using BC which is slower than a normal DB

3. There should be more than 1 writer to a database in order to justify a blockchain, because one of the key features of a blockchain are its immutability, trustlessness and distributed ledger.
   It is an append only DB. As such if there is only one user, trust is implied. Likely no need for a distributed model (aside from a backup of course).

[Bull75rm]

1. Normal databases are cheaper, more efficient, more experienced and there more resources available
2. Waist of money, time and resources
3. Because with 1 writer there is nothing to share and no need for ledger consensus.

[Dora_Csonka]

1,
Creating a normal database is quicker, cheaper and simpler.
2,
Wasting money and time
3,
To be decentralized, you have to more than one person ‘in charge’

• What are the benefits of using a normal database instead of a blockchain?
  It is much faster and more efficient in searching and dealing with queries.

• What do you think the consequences would be of using a blockchain when you in reality don’t need one?
  Potential lost of time and resources as unnecessary implementation takes place.

• Why should there be more than 1 writer to a database in order to justify a blockchain?
  There will not be transparency and trust in the blockchain.

1. What are the benefits of using a normal database instead of a blockchain?
   A normal database is easier and cheaper to implement. Can be quicker to query and may consume less energy.
2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   Redundant effort, greater expense for a less efficient solution. Harder to adapt to future changes.
3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   There is no consensus required if only 1 writer, no issue with trust.

[Vivek20]

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

It is easier and cheaper to implement because there is a lot of history and talent available.

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

Not a good fit can lead to unnecessary complexicy and excessive costs.

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

If there is only one writer there are no collaboration or trust issues.

[thoth]

1. It is more efficient and less costly.
2. Inefficient and more costly
3. In order to verify transactions or inputs

[ble4h]

1. What are the benefits of using a normal database instead of a blockchain?
   A normal database is cheaper in terms of cost, talent, and time to develop.

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 resources, time and effort.

3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   Because blockchain needs consensus. There wouldn’t be a point for consensus when there’s only 1 writer to the database.

1. What are the benefits of using a normal database instead of a blockchain?
   A “normal” database, like SQL is a lot more affordable than developing your own blockchain bases database. SQL is efficient in its performance and there is a lot of previous history on how to use various non-blockchain databases.

2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   Unnecessary resources spent, labor invested only to discover that it was not the right approach from the outset.

3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   One of the main benefits for using blockchain based system is to keep participants (writers) accountable, as blockchain is immutable. This feature is beneficial if there are many writers.
   Why waste time and money in case of just one writer?

1. What are the benefits of using a normal database instead of a blockchain?
   You have more functionality, it is cheaper and easier to incorporate into your business.

2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   Higher cost, harder to change functionality and rules, speed of use.

3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   So that they all can come to a consensus and see if the particular writer is a valid member or to double check to see if the code has any sort of malicious software.

[Pats]

1. Fast transaction speeds.
2. Waste of time and resources implementing the unneeded blockchain.
3. A trustless system is not needed with only one writer.

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

• Normal database like MySQL is easy to setup,maintain and it provides CRUD method which supports many applications when in doubt.
• Normal databases are relational so it becomes much easier to create relations between different entities
• Normal database interact very well with existing centralized iT infrastructure and do need additional resources in the form - New Talent, hardware etc

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

• It can significantly create overhead to maintain the blockchain especially when it do not fit the business model.
• If writers/users are trusted party and they already have consensus among-st them then blockchain will be unnecessary

3. Why should there be more than 1 writer to a database in order to justify a blockchain?
The biggest advantage of blockchain is it creates a trust-less environment and to achieve that it relies on solving a math problem also called “consensus”. In order to achieve consensus, we need to have at least 51% of the users to agree with the change and hence blockchain can only be justified when we have more than 1 writer that can create conflict of interest.

[Jackchap]

A normal database allows update and delete functionality, and is a more straightforward method for users and administrators.

Using a blockchain can introduce some complexity in a traditional environment where records are constantly updated.

If there is only one writer, then then there doesn’t need to be consensus among multiple parties.

[Daniel_L]

1. What are the benefits of using a normal database instead of a blockchain?
   -> Easier/cheaper to implement because there is a lot of history and skills available. SQL is also efficeint

2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   -> Can lead into unnecessary complexicy and costs (waste fo time and resources)

3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   -> One writer only there is nothing to share and hence a blockchain is nit justified

[JoshB]

1. Normal databases are cheaper to use and also faster and more efficient.
2. Expensive to build and time consuming
3. 1 writer = no need for consensus

[Rafael21]

1. What are the benefits of using a normal database instead of a blockchain?
   It is faster, more efficient, and less expensive to set-up and maintain.

2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   Slow down process, benefits will not outweigh cost, and project will fail.

3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   Because blockchain is there to ensure trust and integrity of the data. If there’s only one writer then you don’t need to ensure trust among participants.

[LamouchiM]

• Faster, easier to implement, cheaper solution.
• Waste of time, money, and effort.
• You don’t have to trust anyone.
