1- In business to business,Blockchain increases the trust between parties thanks to instant access to relevant authentic information.

  1. Permissonless BC is public BC, which is a distributed ledger based on cryptographic protocols. Anyone can join without permission by central authority.

  2. Bitcoin, EOS and Ethereum.

4.those who are allowed by central authority to join the network can only join.

5.The permissioned BC is preferred by many companies, because the central authority will secure the data with less cost without loosing their control.

    Only approved people or computer entities have the possibility of running nodes on the network

  2. Why do you think permissioned blockchain networks are preferred by many companies?
    Because they will have more authority on their blockchain, they can decide the level of decentralization, level of transparency, they can decide the algorithm, and decide the governance by the members of the business.

  1. What benefits do blockchain provide in business-to-business collaborations?

The current system is based on trust between the parties. With blockchain the trust is in the system, and all information is immutable. The absolute best way of handling trust in my opinion.

  1. What property of a blockchain does the name “Permissionless” refer to?

It refers to the blockchains that is public for all.

  1. What are 3 examples of permissionless blockchains?

Bitcoin, Ethereum, Bitcoin Cash, or all digital currencies is based on permissionless blockchains.

  1. Who are allowed to join a permissioned blockchain network?

A permissioned blockchain is built to serve a company’s info in closed ecosystems. And used by centralized organizations. That means that the centralized organization will decide who is getting access to the network.

  1. Why do you think permissioned blockchain networks are preferred by many companies?

Because they don’t want intel or information that could be sensitive to others or themselves to be public.

    • Trustlessness: Blockchain is transparent and trustless, so you can validate instead of trust your business partner.
    • Security: Blockchain is immutable. No single person can change data, unless she/he has 51% of the computing power
    • Cut the middleman: No third party is needed to facilitate transactions

  2. Public: If it is a public blockchain, it is permissionless

  3. Bitcoin, Ethereum, EOS

  4. Whoever will be approved by a central authority (Government, Company, Club,…)

  5. Companies like to keep the control on how things are run. Also, companies want to keep certain information private/secret.

1.Block chain has a wide array of applications where the immutable and transparant data needs to be shared, and needs to be trusted by the participants (e,g. the expiry date of a medication production batch should not be altered - It should be trusted information)
2.A Permissionless system really means that anybody can participate in the network, share, and become a part. There are no limitations. The trust is built into the technology/cryptography and this provides the security people require
3. Examples of Permissionless blockchains are Bitcoin, Ethereum and EOS
4.In a permissioned blockchain network, just as with any IT infrastructure, there is administrators who assign certain rights or certain levels of permission depending on the requirements or work position.
5.As many companies deal with proprietary information, and do not want this in the public domain, while still benefiting from the advantages that Block chain brings, a permissioned blockchain would be a good compromise

Bitcoin, EOS,Etherium.

  1. Who are allowed to join a permissioned blockchain network?

The owner of the blockchain only allows those that they trust into the network - the full nodes of that network will be chosen by the creator of the network, and the creator of that network will always determine who will be in the network, and who will not.

  1. Why do you think permissioned blockchain networks are preferred by many companies?

Permissioned blockchains are most used by business because they want control.If you are using a blockchain in business you may have secrets that you don’t want anyone to see.

  1. If businesses opt to use blockchain it can potentially increase the trust and confidence in collaborations because the data shared (assuming the businesses fully opt to use a permissionless blockchain) is transparent, secured and immutable (cannot be manipulated).

  2. Permissionless = does not require permission. In this context, for example, a person does not require to be authorized to use the blockchain, unlike centralized systems.

  3. Bitcoin, Ethereum and EOS.

  4. Only those which are authorized by the central authorities (those with full user access control powers), either a person, a group of persons or computers.

  5. Because traditional businesses operate and profit via business secrets and, normally, owners of such businesses do not wish to share out such information to the public blockchain. They also prefer to allow the persons or stakeholders who they can trust to have access to such information. We still live in an era where a fully trustless environment is hard to implement due to human behaviour in general.

  1. The benefits blockchains provide in “business-to-business” collaborations are; a) Less need for trust between parties (the trust is in the blockchain), and b) Instant access to information.

  2. The property of a blockchain that the term “permissionless” refers to is “Public” - the fact that anyone can interact with the network.

  3. Three examples of permissionless blockchains are; Bitcoin, Ethereum and EOS.

  4. Only approved people or entities are allowed to join a permissioned blockchain network.

  5. I believe permissioned blockchain networks are preferred by many companies because a lot of their information is confidential, and because companies tend to be hierarchical so governance is preferred over consensus.

  1. Eliminates the need for a 3rd party, increases trust, access to information
  2. Any user can set up an address/run a node, interact with network eg. submit transactions
  3. Bitcoin, Ethereum, EOS
  4. Only approved people or entities can join permissioned blockchain networks
  5. Since only approved people can run nodes, execute transactions/smart contracts and read the transaction history, it protects the companies from those who seek to harm it and lets them keep some of their activities private, controlling who can have access

  1. What benefits do blockchain provide in business-to-business collaborations?
    It allows for faster access to secure, reliable, verified information. And removes the need for expensive and time consuming (and potentially corrupt) intermediaries.

  2. What property of a blockchain does the name “Permissionless” refer to?
    It refers to the ability to join the network freely and participate freely by adding transactions or by mining new blocks without needing permission to do so.

  3. What are 3 examples of permissionless blockchains?
    Bitcoin, Etherium and EOS

  4. Who are allowed to join a permissioned blockchain network?
    Only participants that are granted access by the central governance of the blockchain.

  5. Why do you think permissioned blockchain networks are preferred by many companies?
    They allow the company to decide what is openly viewed by the users and not, so they can pick and choose the information they would like to keep private from the blockchain. It allows them to “customise” the blockchain protocol as they see fit so they do not have to have 50% +1 of the network to make changes. This means changes can be made much faster and so it can serve their business better.

    Depending on the type of business, certain companies prefer more central control when concerning their data. For those who prefer to keep their sensitive information private, and only grant access to “trusted” parties for viewing, a permissioned blockchain network would be preferable.
