1. What are the benefits of using a normal database instead of a blockchain?Normal databases are simple to set up, fast and more efficient
2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?expensive, complex to set up
3. Why should there be more than 1 writer to a database in order to justify a blockchain? Transparency and security

1. What are the benefits of using a normal database instead of a blockchain?
   A. Benefits of normal database are its cost effective, fast and efficient and easier compared to blockchain.
2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   A. It will be expensive, no business secrecy, time consuming to name few.
3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   A. When there is more than 1 writer to a database, there is more transparency, remove any middlemen and better security.

1. What are the benefits of using a normal database instead of a blockchain?
   —Its more effective for storing data and its cheaper
2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   —having a blockchain would require more resources, time, and money which can increase a business’s overheads
3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   —for instance if a business deals with various clients they will need to establish transparency and security within their business relationship when coming to sharing data, or financial info

[RCV]

1. More efficient, easier to query database for data, faster computation, cheaper, many people are skilled in normal database.
2. Higher expense, cant make changed to data, slower
3. If there are many writers you would need a trustless system with no intermediaries that all writers can agree to use. Blockchain is useful in this situation due to its transparent and immutable design.

[Agnie]

1. Some of the benefits of traditional database: more accessible, more resources available, cheaper to run.
2. It can be expensive to run and difficult to integrate wit existing IT solutions.
3. Having more than 1 writer creates a decentralised and trustless environment.

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

1. Less expensive (hiring blockchain developers), faster, can use the different types of databases together based on needs, and use of privacy.

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

2. Expensive developers, latency issues, difficult to adjust and make on the spot changes.

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

3. With a blockchain, trust not needed to know who is doing what in the database. If more than the original developer is working on a regular database, trust is needed so that one of the writers does nothing dishonest as normal databases are not immutable like a blockchain.

[Crypto_Daddy]

1. They are cheaper and easier to use

2. It would be more costly and less productive

3. Because trust is already proven by only one person being able to change information

[JBrewer]

1. What are the benefits of using a normal database instead of a blockchain?
   – speed, access control

2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   – cost in manpower and computing power would go up

3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   – you’re using the bc to store many tx’s and if only one user to a db its overkill

[sto]

More effective cheaper and with years of knowhow

You will be doing bunch of time consuming and unnecessary operation in doing blockchain

Its takes to for blockhain but only one for centralized database

[ANV81]

1. What are the benefits of using a normal database instead of a blockchain?
   It would probably be faster to query than a blockchain, and more cost effective to run if you have no need for one.

2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   You’d probably be wasting you time and resources when a standard DB would be a better choice.

3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   With one user, there would be no need for data verification, since there’s no other parties involved. (kinda like Ivan’s coffee )

[JeremyH]

1. What are the benefits of using a normal database instead of a blockchain?
   – Normal database are more effective and faster reading and writing data and is cheaper because of large number of developers and completed projects to gain experience from

2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   – Doing so would increase costs, latency, and would result in something that is the opposite of process improvement

3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   – One writer would be easily identifiable and responsible for the data. A blockchain is expensive, time-consuming, and difficult to implement and would not be ideal for a solution with only 1 writer.

[Crista]

1. What are the benefits of using a normal database instead of a blockchain?
A normal database is easier to run, more time efficient, and less expensive than a blockchain.
2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
It would require more resources in time, money, and energy than needed.
3. Why should there be more than 1 writer to a database in order to justify a blockchain?
The blockchain addresses a range of trust issues that only come up when multiple writers to a database are involved.

[marc.berchtold]

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

• Better performance
• Lower costs
• Easier to use

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

• Higher costs
• Worse Performance
• More difficult and time insitive to develop

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

There is no trust issue with one writer

[laserkavajen]

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

More developers in normal database which will reduce the cost, more history using normal database then blockchain.

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

Waste of time creating this blockchain and of course unusable if i can run a normal database.

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

Blockchain is a trustless network, with only me as permission to write it made everything simple I trust my self!

[Tiffany]

1. shared write access not needed and you have trusted users.
2. possible gas/electricity costs
3. because that is the purpose to gain consensus in a mining topology.

[Dragutin]

1. What are the benefits of using a normal database instead of a blockchain?
   -speed, scalability, inexpensive
2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   -complex, slow, expensive
3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   -I always trust myself, but do I trust another party to keep their word? This is why immutable blockchain can be needed if multi-party transactions are being processed.

[martin-vienna]

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

a) faster
b) cheaper
c) easier to find developers because SQL in “English” in terms of database languages

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

too expensive due to overengeneering

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

because otherwise it must not be a distributed database if there is only one one who “maintains” the database. If only one maintains it, it is per definition central.

• What are the benefits of using a normal database instead of a blockchain?
  Cheaper, easier. Everyone knows how the usual databases work, it’s easy to find expertise and thus quicker and cheaper to set them up. They are ideal if you like centralisation and if the collaborators have very similar interests and trust eachother. There’s no need for certificates and you need far few people involved to set it up.
• What do you think the consequences would be of using a blockchain when you in reality don’t need one?
  Wasted resources. Wasted time. Making things more complicated for no perceivable benefit. You would definitely have to do a cost benefit analysis.
• Why should there be more than 1 writer to a database in order to justify a blockchain?

Blockchain by definition is decentralised, one writer seems the epitome of centralisation.

[Raf.PV7]

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

It would be cheaper as the technology like SQL is more common at the moment, easier to implement, easier to run, easier to scale.

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

As number one, it would be really expensive to implement, then the maintenance, modification & scalability would be difficult.

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

For transparency purposes, if only one writer, one can make the ledger say whatever, instead of having a trustworthy information.

[CocoaCrypto]

1- It’s less expensive, can quickly and efficiently store data, and is easy to integrate with already existing IT systems. It doesn’t require shared write access.
2- It’s difficult to manage and build. It’s expensive, so if not needed, you’d be wasting capital that could be used for other resources. In addition, it can be inefficient in terms of the speed of transactions.
3- Otherwise, you could just have a centralized, regular database system. The idea of having a blockchain is so that information can be trustlessly and securely recorded. If there’s only one person writing, there’d be no need for functions like consensus to verify data.
