Blockchain Decision Tree - Reading Assignment

  1. Normal databases are faster, more efficient and cheaper. They also enable trusted 3rd parties and don’t require shared write access
  2. Higher cost, more memory required, inefficiency
  3. If there is one writer, there is no need for transparency/security that blockchain provides, where multiple writers could have conflicts of interest

  1. The benefits of using a normal database instead of a blockchain are; a) a normal database is faster, more efficient and cheaper, b) there are a greater number of experienced developers available to maintain a normal database, and c) normal databases are easier to build.

  2. The consequences of using a blockchain when one is not really needed is; a) excessive cost, b) loss of efficiency, and c) unnecessary difficulty in its creation and maintenance.

  3. There should be more than one writer to a database to justify a blockchain because if there is only one writer there is no need to check the order of inputs and no need for trust or consensus. If there is more than one writer, there is. So the blockchain is then justified.

  1. What are the benefits of using a normal database instead of a blockchain?
    Normal databases are cheaper to design and maintain as they are not so specialised and dev’s are easier to find. They are faster than a blockchain database.

  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    It will be very expensive. And will mean loss of efficiency.

  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    Because a blockchain records and verifies inputs from multiple entities. You do not require this function if there is only one person inputting data.

  1. What are the benefits of using a normal database instead of a blockchain?
    It is centralized, cheaper and faster since you do not have to wait for validation.
  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 costly mistake which is why you need to think of the pain points you are looking to solve first.
  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    There would be no need for consensus with only one writer and no need for a blockchain.

easier to implement, less costly, faster, less memory needed

if only few people need writing access a blockchain is not necessary
if the writers are known and trustworthy, don’t use BC
if a third party is involved (centralization) a BC is not needed
might need longer timeframe to update data, compared to SQL-DB

the concept of BC and HL seems absurd/obsolete to me, if there is just one writer.
This Channel system ie is shared between different organizations where different
peers/Apps have writing permissions.
(writers in hyperledger are the wallet-users in public blockchain and
peer/orderer/ledger in hyperledger is the miner in public blockchain?)

  1. What are the benefits of using a normal database instead of a blockchain?
  • speed and scalability is higher
  • typically lower costs, because technology is known
  • it is private, so not everyone can see what has been stored in the database
  • one can control permissions
  1. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
  • higher costs
  • lower user adoption due to frustration with speed and scalability
  • even complete boycott of usage due to lack of privacy and control over database
  1. It would be way more efficient to use a centralized database. There is just no need to validate data by multiple parties. The only writer decides what will be stored anyway.

    faster and more effective

  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    Waste of money and energy, not efficient

  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    because with only 1 writer a normal DB is enough. Blockchain needs at least 2 or more to find consensus, which is not needed with a normal DB.

What are the benefits of using a normal database instead of a blockchain?
Using a normal database is normal much easier and cheaper to build a solution due to competency, experience & skills in the field. Other benefits are speed of transactions, query speed and privacy of data.
What do you think the consequences would be of using a blockchain when you in reality don’t need one?
Unnecessary costs, slower (Both economic and time consequences)
Why should there be more than 1 writer to a database in order to justify a blockchain?
Due to transparency and security, if there is only 1 writer, there is nothing shared about the ledger. It is no need for consensus.

  1. Some benefits of using a “normal” database instead of a blockchain are that it is cheaper and less complex to build because there are many use cases involving a “normal” database versus a blockchain. Another benefit of a “normal” database is that information can be queried much quicker.

  2. Some consequences of using a blockchain when you don’t need one is spending extra money, time, and energy unnecessarily. Also there may be private data that should only be accessible to appropriate parties in which case a public blockchain would not be the right choice and could give sensitive data to the wrong people.

  3. Multiple writers with different interests writing to a database are better than only one writer to justify a blockchain because when there is consensus among these writers with different interests that shows the legitimacy of the data within.

  1. What are the benefits of using a normal database instead of a blockchain?
    Processing speed, easy access, blockchain developers are harder to recruit.
  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    High operational cost
    Higher cost for blockchain developers
    Development is time intensive
    Why should there be more than 1 writer to a database in order to justify a blockchain?
    With one writer all concurrency is delegated to one writer. Every transaction will be valid.

  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    expensive and makes you non competitive.
    difficult and unnecessary maintenance
    less efficient because of unneeded requirements

  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    To ensure that there is concencus, transparency and security

What are the benefits of using a normal database instead of a blockchain?
Quicker and easier to implement, easier to find developers

What do you think the consequences would be of using a blockchain when you in reality don’t need one?
Having a system which is over-complicated for its purpose, potentially more difficult to use, wasted costs with implementing, risk of the solution not being used.

Why should there be more than 1 writer to a database in order to justify a blockchain?
If there is only one writer then there is no need for a trustless system as there is only one user. There would be no need for consensus.

  • What are the benefits of using a normal database instead of a blockchain?
    The benefits of using a normal database is that it is cheaper, it is easier to maintain as knowledge of blockchain development is still in its infancy and finding someone to maintain it could be costly.
  • **What do you think the consequences would be of using a blockchain when you in reality don’t need one?**It would be a costly exercise that would not benefit the client in anyway.
  • Why should there be more than 1 writer to a database in order to justify a blockchain?
    With only 1 writer you would not need a blockchain as that 1 person is trustless in himself.

  1. What are the benefits of using a normal database instead of a blockchain?
    A normal database provides a super user the ability to easily edit data stored within it because of it’s centralized nature. This is not the case when it comes to blockchain.

  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    A blockchain is expensive to build, expensive to run, and nearly impossible to edit data contained within. If one isn’t needed for business, it could seriously effect a business’s bottom line.

  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    Because a blockchain’s strength lies in it’s decentralized nature. More than one writer boosts the integrity & security of the data contained within.

  1. What are the benefits of using a normal database instead of a blockchain?
    Fast, easy, cheap due to the central authority and the well known approach
  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one?
    Higher costs in building and maintaining and unsatisfied users. Also the problem of complicated updates and deletes
  3. Why should there be more than 1 writer to a database in order to justify a blockchain?
    Consensus needs n>=2 peers, otherwise there is no need for consensus and therefore no need for dlt

  1. What are the benefits of using a normal database instead of a blockchain? More efficient, centralized, cost effective, and deterministic
  2. What do you think the consequences would be of using a blockchain when you in reality don’t need one? Costly (labor, maintenance, electricity)
  3. Why should there be more than 1 writer to a database in order to justify a blockchain? Because it’s a DLT, implying you should have more than one writer for all the transactions and to secure the network.
