Blockchain Decision Tree - Reading Assignment

[Ernesto]

1 Normal Data base are easier cheaper and more efficient than a block chain database
2 More expensive more time consuming on development more difficult to change functions for people
3 only 1 writer, that means nobody will ever check the information. That only writer is a trusted source, in that case, no point in using a Block chain.

[Zachary21]

1. Less expensive, fast, simple, and efficient.

2. Bottom line, difficulty of making quick and easy changes, and slower speeds.

3. Well, I would say that as long as this one person can fully trust themselves then a standard data-base will work just fine. Lol

[vezuchiy]

1. A normal database is faster, uses less computational power, time sequence could be maintained and have privacy.
2. That could be a waste of resources- time and money.
3. Because with one writer the information is trustful and secured, no need of the blockchain.

1. What are the benefits of using a normal database instead of a blockchain?
   A normal database is much cheaper and quicker to implement and only requires conventional IT skill sets.
2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   The consequences would be that your development and system costs as well as development timeframe are much greater than they need to be.
3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   If there was only a single writer then that writer would by definition be trusted. When trust becomes an issue, then that is a reason for considering blockchain.

[Naz]

1. The benefits of using a normal DB are cost and time efficiency. It’s also a widely used and known technology, meaning it’s easier to develop and to implement it and to find the experts to do the job.

2. Some of the consequences of using a blockchain, when you don’t need one, is that it’s time and cost consuming, i.e. it’s less efficient and it adds ‘stress’ to your business.

3. There should be more than 1 writer to a database in order to justify a blockchain because, consensus requires more than 1 entity.

[jostrings]

1. What are the benefits of using a normal database instead of a blockchain? -
   Easy to find competent developers, it has a track record, it will in many cases be efficient if the writers trust each other and are unified in the purpose of the project

2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   -Harder to find competent developers, inefficient, expensive, unpractical, timeconsuming, opportunity cost, unorganized data in some cases.

3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   -because blockchain writes transactions between 2 parties. Off course i can see the use case to document something for yourself that is immutable and final, but i think the price in most cases don’t justify the value you get back. Problems with transaction documentation can lead to legal issues in some cases. And then it’s practical to have blockchain as documentation for what happened.

[Finu]

1. It´s basically a better idea, if all writers are trusted and there´s no need for decentralize. Normal databases are faster and cheaper for “normal” use.
2. Slower database with no real benefits
3. If only one writer, the database is fully controlled/trusted anyway, no need to use blockchain.

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

A normal database is simple to manage, not as complicated relative to Blockchain, and you don’t need a server farm that require specialized competences (less cost). But there is off course also negative things and costs with a normal database, not mentioned here.

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

You get a expensive solution to manage, loss of invested effort and money, and you probably be the black sheep, so make sure that the “business department” understand how and why to use a private blockchain.

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

The main thing with blockchain is to solve trust problem, if multiple users update information all user gets trusted by the blockchain protocol itself. If there are only one db-admin that write information, then that user already got the trust by the business.

[Danieljd]

1. What are the benefits of using a normal database instead of a blockchain?
   Faster, more easy to implement and cheaper
2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   Unnecessary development costs and time, will be slower than traditional databases and harder to update/change functions.
3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   Otherwise the blockchain is not immutable and all of the trust is based on the 1 writer. Then the benefits from using blockchain gets eliminated.

[MSeeman]

1. A non immutable source of data, a closed, and centralized system

2. Loss of time, man power, and money for start.

3. It’s a good indication of decentralization

• What are the benefits of using a normal database instead of a blockchain?
  They show current value. They are easy to query and read. They are familiar.

• What do you think the consequences would be of using a blockchain when you in reality don’t need one?
  High costs of implementation and knowledge acquisition. Exposure to manipulation.

• Why should there be more than 1 writer to a database in order to justify a blockchain? Because blockchain is a dristributed network of nodes and requires their consensus for transparency.

[Laszlo_Leonardo]

1. save money, quick to get access and give different rights, save time,
2. waste of money and time and resources
3. if a network needs the same rules, a way of trust,or transparency and high security of the data

• What are the benefits of using a normal database instead of a blockchain?
• What do you think the consequences would be of using a blockchain when you in reality don’t need one?
• Why should there be more than 1 writer to a database in order to justify a blockchain?

1. Faster to processing/render, less expensive, only need one public local hard drive, dont need so much energi.

2. Expensive, unnecessary system to build and teach everyone, waste of time, slowing down the work flow.

3. You must be more than 2 in a blockchain, otherwise is unnecessary to have a blockchain.
   better to have a central database instead.

[VICBTC]

• What are the benefits of using a normal database instead of a blockchain?
  much easier and cheaper to build

• What do you think the consequences would be of using a blockchain when you in reality don’t need
  one?
  costly to run inefficient difficult to integrate, slower transactions

• Why should there be more than 1 writer to a database in order to justify a blockchain?
  Blockchain uses consensus to prevent multiple actors/writers from inputing dishonest transactions such as double spending through trustless mechanism. If there’s only 1 writer, there is no need for trust, as they control more than 51% of the nodes (in this case 100%) and input whatever they wish since there is no consensus needed.

[Daniel_Fuchs]

	a. poor user experience
	b. higher ressource consumption

	d. higher cost
	
3. Why should there be more than 1 writer to a database in order to justify a blockchain?
	a. with one writer you don't need a trustless system

[carmen1408]

1. Cheaper, faster, more efficient, can be controlled.

2. More expenses, time consuming

3. Security

[Samuel_Inclan]

1. What are the benefits of using a normal database instead of a blockchain?**
   Because it is easy to implement, more user-friendly and cheaper.

2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
   Costly plus great complexity for implementation and inefficiency and slowness.

3. Why should there be more than 1 writer to a database in order to justify a blockchain?
   To guarantee the transparency and reliability of the data.

[Wade]

1. Easier and cheaper to build and maintain.
2. Poor user experience
3. If you do not need security and transparency there is no need for a single entity blockchain.

[confusius]

A database can store this data much better and process it faster as well since it does not require multiple nodes to run each piece of data.

A waste of resources, time and money.

Because of transparency and security.

[matty.t]

1. Cheaper to set up, more efficient and speed of transactions
2. It is expensive and inefficient
   3.Transparency and security
