  1. What are the benefits of using a normal database instead of a blockchain?
  • Cheaper, easier to use and amend as needed.

  1. What do you think the consequences would be of using a blockchain when you in reality don’t need one? The main aspect would be the needless high costs and time wasting. In addition to the burden of having to get everyone aligned with learning a new technology that they don’t require in the first place.

  2. Why should there be more than 1 writer to a database in order to justify a blockchain? The trustless aspect of a blockchain only comes into play when trust is an issue. If there is only one writer to a database there is no trust issue to solve.

  1. It is more efficient because it is faster and cheaper.
  2. More expensive to operate, time inefficient.
  3. Trust in accurate information for auditing and regulation. Since smart contracts are involved, both would need consensus.

  1. What are the benefits of using a normal database instead of a blockchain?
    Centralization, flexibility and control, privacy
  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    HIgher maintenance costs, less flexibility and efficiency
  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    Because a blockchain’s based on consensus of multiple parties. 1 is not a multiple party.

  1. What are the benefits of using a normal database instead of a blockchain?
    Speed, ease of use, lower costs, easy to implement and deploy, many devs available to build one

  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    Will cost more to build, not many devs available, lower performance

  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    Because it is safe to say that 1 writer can trust himself and has his own interest unified

1- Databases are cheaper, quicker easier to read and write data, much more efficient and flexible.

2- The consequences are that it will be unprotitable, slower and you won’t the flexibility to adapt it to the needs of your business.

3- If there is only one writer there is no need to be concerned about the security as there is a trusted writer.

  1. What are the benefits of using a normal database instead of a blockchain?
    They are much easier to work with, there is more expertise available with these skill sets vs a blockchain, it is much quicker to build, it is easier to adapt to and make changes, cost will be lower, performance is generally faster at this time.

  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    Unnecessary increase in development time, higher cost, more difficult to develop, solution is likely to be more prone to errors due to higher and scarcer skill set required to develop, slower performance

  3. Why should there be more than 1 writer to a database in order to justify a blockchain? There should be more than one writer to justify a blockchain because two or more writers is less trustworthy situation than a sole writer. Blockchains work better in trustless situations. In addition a blockchain provides more transparency with the transactions.

  1. It is cheaper, faster and way easier to build.
  2. The processes will run slower than expected and the decentralization will not justify the real business need.
  3. If there is only one writer than there is no need for a consensus from different actors, as well as there are no trust issues, which may arise when there are more writers.

  1. Traditional DB is faster, easier to work on, less expensive than BC.
  2. Pay extra money :wink: and every will become much slower…
  3. So there is no TRUST between intermediaries, only math/physics and some love

  1. Normal database is faster therefore more efficient. Not as expense to implement than block chains. Skills already developed and therefore more support.
  2. Will be spending unnecessary funds and will also be harder to change the rules associated to the block-chain. You will also be compromising on the speed.
  3. One writer in a block chain is basically describing a central database. Therefore 2 or more is required for a block chain as consensus is needed.

  1. A normal database is probably cheaper, less complex to manage, faster in registering information and more efficient as for the current scenario. If you don’t need a decentralized, secure, transparent, immutable ledger, a normal database is more suitable.
  2. It would make processes overly complex, make the investment less profitable, reduce efficiency, require proper regulatory compliance.
  3. Because if there is only one person enabled to write on the database then the blockchain is not really necessary, as it is actually useful if you need to verify and validate multiple information flows from different nodes. When you only have one authorized party, then the information is not subject to verification (because the only one to be able to verify would be the writer itself, which makes it useless). Using a blockchain in such way would be a waste of resources, time and potential.

1. What are the benefits of using a normal database instead of a blockchain?
Compared to a blockchain, a normal database is easier, faster and less expensive to set up.

2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
Consequences would be lost of time in development, unnecessary spending and inefficiency.

3. Why should there be more than 1 writer to a database in order to justify a blockchain?
With no more than one writer there is no need of transparency or consensus control.

  1. A normal database is cheaper, easier to build and maintain, faster, more scalable.

  2. You are wasting a lot of time and costs. Your application is also not as effective and efficient as it could be.

  3. If there just one 1 writer you should use a normal database (SQL) for your application, because a blockchain with only 1 writer (that means a central supervisor/authority) is just the same as a normal database (but with the disadvantages of a blockchain). It makes no sense to implement such a use case in a blockchain.

  1. What are the benefits of using a normal database instead of a blockchain?
    More talent available, cheaper and faster.

  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    it would result in waste of time and resources as well as decreased efficiency.

  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    If there is only one writer needed, a simple database can be used.

1.Traditional centralized databases can be customized by the administrator depending on business requirements. When properly managed, a database system can handle large volumes of data and process thousands of transactions per second.Today’s databases are designed for both high volume transaction processing and data analytics. This means they are tried, tested and true for mission critical operations in enterprise production environments.

2.Unnecessary costs, waste of time and recources.

  1. If there is 1 writer there is no need for trust. Blockchains are useful for sharing data with a group of non-trusting parties.

  • What are the benefits of using a normal database instead of a blockchain?
  • Its going to be faster, cheaper and easier to build

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

  • Potential unnecessary waste of capital & time

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

  • If theres only one writer than there is no viable need to require using a blockchain (zero consensus required)

More cost efficient; Can be faster; Other databases includes modification or deletion of data, in some case can be beneficial.
2.
Loosing energy, money, and time.
3.
Avoiding mistakes, revisit data accuracy.

  1. Normal databases are cheaper, more, and faster to set up if all users are trusted and have common goals, such as employees of the same company.
  2. Using a Blockchain when it is not needed will result in slower transaction times, higher costs, and frustrated users.
  3. One writer does not make a consensus and should not be trusted.

1-What are the benefits of using a normal database instead of a blockchain?
It is cheaper and easier to keep functioning.

2-What do you think would be the consequences of using a blockchain when you don’t really need it?
The real advantage of the blockchain is its irreversibility. This more expensive system is profitable to be used when the parts are not entrusted or when that may have some potential conflict of interests. When the parts fully trust one another, have no potential conflicts, or even there is only one part involved in the data management it makes no sense to store datas on a blockchain.

3-Why should there be more than 1 writer in a database to justify a blockchain?
For the same reason I said at point 2.
