  1. A normal database can be faster and can be fully controlled
  2. Expensive and can overcomplicate
  3. Having more than one writer and a decentralized database is what offers security.

  1. Cost efficiency, full control and fast

  2. Higher costs, unefficient system with higher difficulty

  3. Trust and security increases when it is not on one persons shoulders.

  1. trust is an issue, higher query speed, the control is in the hand of one or a group of selected members.
  2. slow working speed & cost intensive
  3. if you only have/need 1 trusted source, you donā€™t need a trustless network were the everyone trusts the protocol

  1. Its efficient fast and cheaper. It is also easier to find competence regarding the installation and governance of the database.
  2. It would be expensive, unnecessary and would not have any functionality. This could be called the FOMO-effect, organization implement a new technology on the notion that it is new and without having a special use case for it.
  3. There would not be any ā€œshared consensusā€ and the blockchain would be unnecessary.

  1. What are the benefits of using a normal database instead of a blockchain?
    Cost. Less complexity for implementation. We know what to expect and can easily find the resources to implement a normal database. We canā€™t say the exact same for blockchain because itā€™s a new technology.

  2. What do you think the consequences would be of using a blockchain when you in reality donā€™t need one?
    Cost. Using blockchain when not needed might incur unnecessary cost.

  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    If the writers donā€™t have a unified interest and/or are not know and trusted, blockchain will provide a solution that is trustless.

  1. What are the benefits of using a normal database instead of a blockchain?
    Itā€™s faster, and easier to set-up and use. More developers know that technology.
  2. What do you think the consequences would be of using a blockchain when you in reality donā€™t need one?
    It will likely take longer to set-up and develop your solution and it will normally be slower than a traditional database project.
  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    For consensus. Otherwise it is just like a db administrator with all authority

1- A normal database is easier to use and cheaper to build. If itā€™s not required security, immutability, transparency, and other blockchain attributes, a normal database is enough

2- Higher costs and time-consuming in the beginning

3- If only 1 writer the security and the trust is only dependent on one person, that way was better to be in a traditional database

  1. easier and cheaper to manage.
  2. Confusion, cost, and lower speed of use.
  3. Otherwise there is no need for it to be distributed.

  1. cheaper/ quicker to get set up/ easier to find database talent/ higher transaction throughput/ more likely to integrate with other business software/ more control

  2. slower transaction throughput/ more expensive/ not compatible with other business software by default

  3. Because the entire thing is based on managing trust among unknown users attempting to edit the database

  1. What are the benefits of using a normal database instead of a blockchain? More efficient, private, and less expensive
  2. What do you think the consequences would be of using a blockchain when you in reality donā€™t need one? Higher expense, less efficient, and not private.
  3. Why should there be more than 1 writer to a database in order to justify a blockchain? For security and ensure trustless

  1. The benefits of using a regular database instead of blockchain are that it is less expensive and easier.
  2. Using a blockchain when you donā€™t really need one would be an expensive waste of time and resources.
  3. A blockchain is for the purpose of consensus and transparency. If those are not the aim, then a regular database should do the job.

    Controle, Faster and cheaper to manage and implement
  2. What do you think the consequences would be of using a blockchain when you in reality donā€™t need one?
    Wasted time and cost
  3. Why should there be more than 1 writer to a database in order to justify a blockchain? Transparency and security No need for consensus if there is only one writer

  1. Itā€™s easier to set up, to use, less writers required, cost effective, ā€¦
  2. You might spend of lot of unintented energy. Cost might be unreasonably high.
  3. Not a single party should determine all. Blockchain is all about decentralization.

  1. Cheap and easy development (no blockchain developers needed), fast queries and transactions.
  2. Besides more expensive development, the whole project might fail because the main business case either would not have been solved or solved inefficiently. Investors wonā€™t be happy.
  3. If only one entity writes to database (or plain text file), there is no need in a trustless solution even if you want to have all transactions public. One writer does not doubt his own actions and trusts himself.
    In the case of multiple writers, the blockchain makes more sense if they need equal or transparent rules for writing. The more writers are participating, the more trustless the solution must be to make sure nobody is cheating - and the blockchain is the most trustless solution know to humankind at the moment.

  1. What are the benefits of using a normal database instead of a blockchain?
    centralized trusted and unified writers, easier to integrate and cheaper to setup and maintain
  2. What do you think the consequences would be of using a blockchain when you in reality donā€™t need one?
    it would be an never ending project, resulting in higher cost spending and the danger of creating a presedent within the organisation against Blockchain
  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    to maintain the consenus and transparency.

High cost and time consuming.

If only 1 writer you donā€™t need trustless blockchain tech cause thereā€™s no one to distrust.

  1. What are the benefits of using a normal database instead of a blockchain?
    One benefit is the ease of use. Traditional Dbs are well-known. The tools and the professionals are available. A traditional Db is also more performant as no consensus is needed.

  2. What do you think the consequences would be of using a blockchain when you in reality donā€™t need one?
    Added complexity, lower performances.

  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    Because no matter what database technology we are using, a single writer is basically a private store.

  1. What are the benefits of using normal database instead of a blockchain?
    A normal databse is much cheaper and quicker to implement and only requires cnventional IT skill set.
  2. What do you think the consequences would be of using a blockchain when you in reality donĀ“t need one?
    The consequences would be that your development and system cost as well as develoment timeframe are much greater than they need to be. In other words: Its not efficient!
    3.Why should there be more than one writer to a database in order to justify a blockchain?
    If there was only a single writer then he would by definition be trusted. When trust becomes an issue, then its a reason for considering blockchain!

  1. What are the benefits of using a normal database instead of a blockchain?
    A normal DB is benefits to store content that does not require consensus, requires faster access and can be build quickly with conventional IT skills.
  2. What do you think the consequences would be of using a blockchain when you in reality donā€™t need one?
    Expensive , Time consuming & inefficient outcome
  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    The issue of trust come into play only when u have two parties involved and Blockchain helps to drive consensus & transparency
