  1. benefits b2b blockchain collaborations:
  • increased trust between parties
  • quick and reliable information
  • no need for middlemen
  1. permissionless blockchains have the following characteristics:

  • anyone can take part on it without asking for access, anyone can see all the history of transactions, do transactions etc… (they are “public”)

  • they are decentralized: there is no owner of the data, no central administration

  • anonymity: personal information not required. However we can’t see it as full anonymity

  • some form of consensus (proof of work, proof of stake are the two most used) is used to add transactions to the blockchain.

  1. bitcoin, ethereum, litecoin

  2. those who are foreseen by the blockchain owner/s.

  3. reasons for permissioned blockchains:

  • scalability (no need for high decentralization)
  • participants are chosen by owners
  • secure registration and storing of transactions

    Because that has how it has always worked, they like to control and be able to manipulate figures if needed. They can choose approved people they trust and securely record transactions and exchange inoformation privately between themselves.

    The blockchain can be easily updated and improved.

  2. Anyone can use and join the network without permission from an authority.
    Works in a trust-less environment. No central authority or person manages the blockchain.
    The ledger of transaction is immutable and can not be hacked, changed, destroyed or revised.

  3. BTC, Eth, EOS, Cardano

  4. People who have been approved by an authority or owner of the block chain.

  5. They scale better, are easier to maintain, change and update. Security is provided by selecting participants rather than employing consensus algorithms that can require resources to operate. An incentive program is not required to approve transactions. The block chain can be tailored to a companies specific needs and is therefore more efficient and streamlined.
