Blockchain 101: A Beginner’s Guide to Understanding the Technology at EMBA Global Network Week
Blockchain technology, the backbone of cryptocurrencies like Bitcoin and Ethereum, is a decentralized, digital ledger that records transactions across multiple computers. Decentralization, the core feature of blockchain, makes it distinct from traditional databases and financial systems. Harnessing the power of distributed networks, blockchain operates independently of any single entity, making it more secure and resilient against hacks and fraud.
How Does Blockchain Work?
To understand blockchain, let’s take a closer look at its functional aspects. Each transaction on the network is verified and recorded with an encryption algorithm in a block. Once the block is filled with transactions, it’s added to a chain of previously verified blocks – thus, the name ‘blockchain’. The result is an unalterable and transparent record of transactions.
Key Components of Blockchain
Decentralized Network:
As mentioned earlier, decentralization is the backbone of blockchain. It allows participants to interact directly with each other without requiring intermediaries like banks or clearinghouses.
Cryptography:
Blockchain utilizes advanced cryptographic techniques to secure transactions, ensuring that every participant has access to a tamper-evident record. It’s important to note that this doesn’t mean the identities of participants are concealed – rather, the transactions themselves remain anonymous and secure.
Consensus Mechanisms:
Blockchain networks rely on consensus mechanisms to validate transactions and prevent double-spending. The most common consensus mechanism is Proof of Work (PoW), which requires users to solve complex mathematical problems to add new blocks to the chain.
Benefits and Applications of Blockchain
Blockchain offers numerous benefits, including increased transparency, security, and efficiency. Industries like finance, healthcare, logistics, and supply chain management are exploring its potential applications to revolutionize the way they operate.
In conclusion:
Blockchain technology represents a groundbreaking innovation, enabling decentralized, transparent, and secure transactions. Its applications extend far beyond cryptocurrencies, making it an essential topic for business leaders to understand at EMBA Global Network Week.

The Basics of Blockchain Technology
Decentralization and distributed databases
Blockchain technology is a revolutionary digital ledger system that offers decentralization and distributed databases. Unlike traditional centralized databases, which are managed by a single entity, decentralization allows multiple participants to validate and record transactions across a network. This decentralized nature brings several advantages, including:
Elimination of intermediaries
Decentralization removes the need for intermediaries, reducing costs and increasing efficiency. Transactions occur directly between parties.
Enhanced security
Decentralization also improves security, as there is no single point of failure. Each participant maintains a copy of the database, making it resilient to attacks.
Blocks, chains, and consensus mechanisms
At the core of blockchain technology are blocks and a chain of those blocks. Each block contains multiple transactions, creating an immutable and time-stamped record. Once a block is added to the chain, it cannot be altered without consensus from the network.
Structure of blocks and their sequence (chain)
Blocks are digitally signed, ensuring data integrity. Once a block is filled with transactions, it is added to the chain, which creates an unbroken chain of records.
Consensus algorithms: Proof of Work (PoW), Proof of Stake (PoS), Delegated Proof of Stake (DPoS)
Consensus algorithms
- Proof of Work (PoW): Miners compete to solve complex mathematical problems, adding the next block and earning rewards.
- Proof of Stake (PoS): Validators are chosen based on their stake in the network, reducing energy consumption and increasing efficiency.
- Delegated Proof of Stake (DPoS): Validators are elected by token holders, creating a more streamlined consensus process.
Public and private Blockchains: Characteristics, use cases, and implications for businesses
Blockchain technology offers both public and private implementations, each with distinct characteristics:
Public Blockchains (e.g., Bitcoin, Ethereum)
Public blockchains are open to anyone and offer transparency. Their decentralized nature makes them ideal for cryptocurrencies and decentralized finance (DeFi) applications.
Private Blockchains
Private blockchains
- Are restricted to authorized participants.
- Offer greater control and privacy.
- Can be used in industries like finance, healthcare, and supply chain management for secure data sharing and recordkeeping.
