Unlike traditional databases, which are managed by a central authority, blockchains are decentralized and distributed across multiple nodes. This eliminates single points of failure and enhances security.

Transactions on a blockchain are visible to all participants, fostering transparency and trust. Each transaction is recorded in a block, which is then added to a chain of previous blocks.

Once a block is added to the blockchain, it is nearly impossible to alter or delete. This immutability ensures the integrity of the data and prevents tampering.

A user initiates a transaction, which is broadcast to the network.

Transactions are grouped into a block by a node (miner or validator) in the network.

The block is validated through a consensus mechanism, such as Proof of Work (PoW) or Proof of Stake (PoS), to ensure its accuracy and legitimacy.

Once validated, the block is added to the existing blockchain, and the transaction is considered confirmed.

The updated blockchain is propagated to all nodes, ensuring that the transaction is recorded across the entire network.

Miners compete to solve complex mathematical puzzles, and the first to solve the puzzle gets to add the block to the blockchain. Bitcoin is the most well-known PoW-based blockchain.

In a Proof of Stake system, validators are selected based on the amount of cryptocurrency they are willing to stake as collateral. The more they stake, the higher their chances of being chosen to validate transactions and create new blocks. This method is more energy-efficient than Proof of Work (PoW) and promotes long-term network security. Ethereum 2.0 is one of the most notable projects transitioning to PoS to enhance scalability and reduce energy consumption.

Stakeholders elect delegates to validate transactions and create new blocks. DPoS aims to enhance scalability and reduce centralization.

Smart contracts automate processes, reducing the need for intermediaries and minimizing errors.

Once deployed on the blockchain, smart contracts are immutable and tamper-proof, ensuring that all parties adhere to the agreed terms.

Smart contracts can be used in various applications, including financial transactions, supply chain management, and digital identity verification.

dApps operate on public blockchains, providing transparency in how data is managed and transactions are executed.

The decentralized nature of dApps enhances security by reducing single points of failure and ensuring that data is distributed across the network.

Popular dApps include decentralized finance (DeFi) platforms, non-fungible token (NFT) marketplaces, and blockchain-based gaming platforms.

Digital currencies like Bitcoin and Ethereum that serve as a medium of exchange.

Tokens that provide access to a specific product or service within a blockchain ecosystem. Examples include Binance Coin (BNB) and Chainlink (LINK).

Tokens representing ownership of traditional assets, such as stocks or real estate, and subject to regulatory oversight.

Facilitating seamless transactions and data exchanges between different blockchains.

Solutions like Polkadot, Cosmos, and Chainlink are working on enhancing interoperability.

Technologies built on top of existing blockchains to improve transaction throughput and reduce congestion. Examples include the Lightning Network for Bitcoin and Optimistic Rollups for Ethereum.

A technique that involves dividing the blockchain into smaller, more manageable pieces (shards) to increase transaction processing capacity.

Protocol upgrades, such as Ethereum 2.0, aim to enhance scalability through changes to consensus mechanisms and network architecture.

Cryptographic techniques that enable transaction verification without revealing sensitive information. zk-SNARKs and zk-STARKs are examples of zero-knowledge proofs.
