2.1. Definition and Basics

Blockchain technology is best described as a decentralized and distributed ledger system that aims to ensure transparency and decentralized data validation through consensus in a network of distributed entities [4]. These entities, also known as block miners or crypto miners, run their own nodes to validate transactions and mine blocks in the network. The consensus protocol requires decentralized consensus to be reached amongst the participating nodes to transition any state of a block or ledger with new transactions included in newly mined blocks. The blockchain network can be either permissionless and publicly distributed or permissioned for enterprise use. Each block in the blockchain contains a hash pointer of its preceding block, ensuring immutability and making it impossible to alter the state of ledgers retroactively. Additionally, the header of every block contains a cryptographic hash of the preceding block, creating a chain of linked blocks.

Moreover, blockchain technology utilizes distributed ledgers, cryptographic hash algorithms, and time-stamped transactions to achieve immutability and consensus among its users [5]. This technology has proven to be disruptive in several industries due to its properties such as permanence, tamper-resistance, accessibility, data integrity, and privacy. However, it is important to ensure that a blockchain implementation retains decentralization and integrity to fully leverage its benefits. Furthermore, the technology has the potential to create displacement in administrative jobs due to its ability to reduce redundancy and manual tasks, leading to the creation of new jobs focusing more on technical skills.
