1- Makes it more transparent as everything is recorded on the blockchain, eliminates third parties, people can transact peer to peer with increased trust.

2- Means that everyone can participate, these are public blockchains such as Bitcoin or Ethereum.

3- Ethereum, Bitcoin and EOS.

4- Only trusted nodes are allowed to join the network

5- They are cheaper to run due to easy consensus, therefore they are faster. There is no mining or cryptocurrency required to achieve consensus.

  1. Decentralization, transparency, digital assets, anonymity
  2. Permissionless refers to who can control the blockchain (must have network consensus), because in many cases a private organization will retain this control but still take advantage of the other features of blockchain networks
  3. Bitcoin, Ethereum, EOS
  4. Anyone
  5. Because they need to retain control and cannot reveal company secrets to the world.

1.The main benefits are the security and immutable of the blockchain network for data sharing between business to business. Not only that it eliminates the costly third party (parties) from the process to make the transfering of value/asset/data more effcient such as peer-to-peer fashion(P2P) but also to increase trust when verifying data on the chain.
2. Permissionless is the property of blockchain that is called decentralization system that has no central authority.
3. The three examples of permissionless blockchains are Bitcoin,Ethereum and EOS.
4.People or entities that are approved by a particular centralised organisation to participate in their network.
5. Permisioned blockchain prefer by many companies because they want to have control on their assets or data for their own interest.

  1. Increases trust between business because is tamper resistant and the information is easily accesible for users.
  2. Permissionless means everyone can access and make use (participate) of the blockchain, no previous authorization from a central authority is neeeded.
  3. Bitcoin, Ethereum and EOS among others
  4. Only users previously authorized by a central authority
  5. Because of the posibility of control from a central point, the ability to make changes without the concensus from all participants of the blockchain, just the designated ones. Control of the different permisions of each user (tier based)

  2. public
  3. Bitcoin, Ethereum, and EOS
  4. The governing party controls who can join the private blockchain
  5. Private blockchains are preferred because the information the companies put into the blockchain should only be available to people who need access to that information. What can and cannot be seen can be controlled.

  1. When it comes to b2b collaborations, Blockchain ensures an increased trust between parties and instant access to relevant, authentic information. It allows the various members that collaborate to be aware of what happens at what time, while insuring them the goodness of the information they can access.
  2. It refers to the fact that this kind of Blockchain is not based on a set of permissions to allow users to access data and interact with the network by creating and reading entries. It is basically the public type.
  3. Bitcoin, Ethereum and EOS.
  4. Only approved people, generally from within the organization which created the permissioned network or from other authorized organizations.
  5. Because they have the benefits of blockchain in terms of transparency and integrity of data, but at the same time access is provided only to specific members. This allows companies to have a verified ledger which prevents tampering but at the same time is under their control.

In case of business to business collaborations blockchains enable the business between two strangers without needing a third party or an intermediary. Through the blockchain trust and transparency is created and now companies can do business with strangers without even knowing them. That being said expensive third parties are not needed anymore which results in a completely new trust level which never existed before. The benefits which results are the following: trust, transparency, secure, everybody has access to all information anytime (in case of permissioned they have access to the information they are only allowed to have), reduce costs and immutable against changing of data/value/transactions.

  1. Permissionless means in this context a public blockchain to which everybody has anytime access to and can read historical data and can also participate in the network instantly. Everyone is allowed to participate in the network and can run a node or add transaction/ transfer value in this public blockchain. There is no central authority (no censorship, no restricted access), so nobody can prevent somebody from using the blockchain.

  2. Bitcoin, Ethereum, EOS

  3. A permissioned blockchain network consists of different members which decided to participate in a closed network/ or build a close ecosystem based on blockchain where only valid/trusted members/entities can join this blockchain and can participate. More or less you could see this a a central controlled/governed blockchain. The validiation of transactions/data/values is done by certified/approved nodes which are chosen by the ecosystem. That being said the access to the information etc. is limited to the members who are in the permissioned blockchain network. Without being accepted as a member you cannot use the blockchain.

  4. Information from companies are mostly very sensitive which means they donĀ“t want to provide it to the public and therefore also to their competitors. They donĀ“t want to show to the public or other companies any transaction about their money or giving them information about their supply chain (amount of products being produced and sold, where do they buy it, what are the conditions of goods for being accepted (e. g. temperature of food), which products a company need for manufacturing their products). That being said companies want to have control who have access to their information. These are some points for companies. But when you think of the health sector there should be also only permissioned blockchain be used because of data protection. Just imagine, a company who want to hire/fire someone has access to a public blockchain where information about your health is stored. They could see how ā€œillā€ you are and decide to not hire you because of this. So, to protect the company itself they will use only permissioned blockchains.

1.In business-to-business scenarios, blockchain networks allow for increased trust between parties, and instant access to relevant, authentic information. This is so thanks to the fact that blockchains provide a historical record of all transactions, alongside the means to record these entries. Transparency, secure transactions, no third party involved, transfer of digital assets between 2 parties.

2.Permisionless blockchain networks allows every user to create a personal address and begin interacting with the network, by submitting transactions, and hence adding entries to the ledger. Trustless environment no central authorithy and anyone can run the software.

What property of a blockchain does the name ā€œPermissionlessā€ refer to?
They allow every user to create a personal address and begin interacting with the network, by submitting transactions, and hence adding entries to the ledger. Additionally, all parties have the choice of running a node on the system, or employing the mining protocols to help verify transactions.
