Blockchain Network

Understand how blockchain networks work

Types of Consensus Mechanisms

Proof-of-work (PoW) and proof-of-stake (PoS) are two of the most prevalent consensus mechanism algorithms, used to validate transactions and add new blocks to the chain. In PoW, miners compete to solve complex mathematical problems to add new blocks to the chain. The first miner to solve the problem gets to add the block and receives a reward in the form of cryptocurrency. PoW is energy-intensive and requires specialized hardware, making it less accessible to small miners.

Can blockchain network be hacked?

Blockchain technology has various inherent security features that make it challenging for attackers to corrupt. Even though hackers can potentially take control of a blockchain, they can likely steal digital tokens from sources such as cryptocurrency exchanges or wallets.

Transparency in blockchain network

Blockchain is transparent because it enables all network participants to view and track transactions. The distributed nature of blockchain ensures that all participants have access to the same information and that transactions are recorded immutably. This transparency can foster trust among network participants, as it eliminates the need for a third-party intermediary and enables more efficient and secure transactions.

Security in blockchain network

The security of blockchain networks is a fundamental feature built on consensus, cryptography, and decentralization principles. Transactions are validated and agreed upon by a consensus mechanism (authorized users), and each new block is connected to all previous blocks in a tamper-proof way. The blockchain network is designed to be highly secure, with the use of cryptographic techniques making it impossible to alter data. With no single point of failure, blockchain networks are also resilient against cyber attacks, ensuring the integrity of the transactions and data stored on the network.

What is Decentralization?

Decentralization refers to the transfer of authority and decision-making from a centralized entity (individual, organization, or group thereof) to a distributed network. Decentralized networks are intended to reduce the amount of trust that participants must place in one another, as well as prevent members from abusing power or control over one another in ways that would be detrimental to the network’s operation.

What is a Smart Contract?

Smart contracts are simply programs that are stored on a blockchain network that run when specific conditions are met. They are commonly used to automate the execution of agreements, allowing all parties to immediately know the outcome without involving intermediaries or wasting time. In addition, smart contracts can also automate workflows by triggering the next action when conditions are met. This makes the process more efficient and eliminates the need for intermediaries, ultimately saving time and reducing costs.

What are Immutable records?

Immutable records refer to data entries that cannot be altered, deleted or falsified once they have been recorded onto the blockchain network, which ensures the integrity and transparency of data, making it a reliable and trustworthy source of information. This is due to the distributed and decentralized nature of the blockchain, where each block in the network contains a unique cryptographic hash, timestamp, and reference to the previous block.

What is a Distributed Ledger?

Distributed ledger technology (DLT) is a digital system used for recording asset transactions. Unlike traditional databases, DLT records transactions and their details in multiple locations simultaneously without the need for a central data store or administration function. Blockchain is a prominent example of distributed ledger technology. It enables all participants in the network to access immutable records of transactions, which are recorded only once. This shared ledger eliminates the duplication of effort that’s common in traditional business networks.

What is Blockchain?

Blockchain is a decentralized, distributed and public digital ledger that is used to record transactions across multiple computers in a way that makes it impossible to change previous records without altering all subsequent blocks and gaining consensus from the network as a whole. It was originally developed as the underlying technology for the cryptocurrency Bitcoin, but it has since found use cases in many other industries, including finance, healthcare, supply chain management, and digital identity.
