According to Blockchain for Dummies, " Blockchain has its title to method by which it stores transaction information in blocks connected to create an chain. The number of transactions increases as will the blockchain. Blocks are used to record and verify the timing and the sequence of transactions. They are later recorded on the blockchain within a separate network that is governed by rules that are that are agreed upon by network's participants.

"Each block has an hash (a digital fingerprint or unique identification number) as well as timestamped batches of legitimate transactions, and the hash of the prior block. The hash of the previous block links the blocks and blocks, and blocks the alteration of any block or a block from being placed between two block." In the theory of things, the technique renders the blockchain impervious to manipulation.

This course will assist you in attaining the highest standards in this field.

The four main concepts behind blockchain are:

  • Shared ledger. Shared ledgers are an "append-only" distributed system of record that is shared within a network of business. "With shared ledgers transactions are only recorded one time, which eliminates the duplication of effort typical to conventional business network."
  • Permissions. Permissions guarantee that transactions are safe verified, authenticated and verified. "With the ability to restrict the network's participation, companies are able to more easily adhere to laws on data protection that are outlined by the Health Insurance Portability Accountability Act (HIPAA)" and the EU General Data Protection Regulation (GDPR).
  • Smart contracts. Smart contracts are "an arrangement or set of guidelines that govern a commercial transaction. It's recorded in the blockchain and executed in an transaction."
  • Consensus. With agreement, the parties consent to the verified transaction on the network. Blockchains use a variety of consensus mechanisms, such as the proof of stake, multisignature as well as the PBFT (practical Byzantine fault tolerance).

Every blockchain network is comprised of a variety of participants that play these roles, for example:

  • Blockchain customers. Participants (typically business users) who have permission for joining the blockchain network and make trades with network members.
  • Regulators. Blockchain users with special privileges to monitor the transactions taking place on the network.
  • Operators of blockchain networks. Individuals who have specific authority and permissions to design, develop and manage and monitor the blockchain network.
  • Certification authority. Individuals who issue and manage the various types of certificates needed for a permissive blockchain
