Nebula Marketplace on Cardano is a decentralized marketplace platform designed for trading Non-Fungible Tokens (NFTs). Built on the Cardano blockchain, Nebula offers a marketplace where users can create, buy, sell, and trade NFTs in a decentralized and secure manner. The marketplace aims to leverage Cardano’s scalable, secure, and low-fee infrastructure to provide an efficient environment…

A faucet on the Cardano blockchain is a service or application that provides users with small amounts of test ADA (tADA) or other Cardano native tokens for free. These faucets are primarily used in testnets—the blockchain networks used for testing before deploying to the Cardano mainnet. Faucets help developers and users experiment with transactions, smart…

Record-keeping models refer to the frameworks or methods used by blockchain systems (and other digital platforms) to maintain, track, and validate data or transactions in a transparent and verifiable manner. These models ensure that records, such as financial transactions, ownership of assets, or legal agreements, are accurately captured and remain immutable over time. Blockchain technologies,…

A coinbase transaction is the first transaction in a newly created block on a blockchain, and it is used to reward the block producer (miner or validator) for successfully creating and adding the block to the blockchain. This transaction is special because it creates new cryptocurrency out of thin air, which is the mechanism by…

The Longest Chain Rule is a fundamental concept in blockchain consensus mechanisms, particularly in Proof of Work (PoW) systems like Bitcoin. It states that the valid blockchain is the one that has the most accumulated work, meaning the chain with the most blocks or the greatest amount of computational power (difficulty) invested in it. In…

CIPs (Cardano Improvement Proposals) are formal documents that outline proposed changes, enhancements, or new features for the Cardano blockchain. They are designed to provide a structured process for suggesting and discussing improvements to the Cardano ecosystem. CIPs are similar to other blockchain improvement systems like BIPs (Bitcoin Improvement Proposals) or EIPs (Ethereum Improvement Proposals). They…

Proof-based consensus algorithms are mechanisms used in decentralized networks (like blockchain systems) to achieve agreement on the state of the system, ensuring that all participants (nodes) agree on the same version of the data (e.g., transactions) without a central authority. These algorithms are based on requiring participants to provide a “proof” to validate their participation…

KYC, or “Know Your Customer,” is a process used by financial institutions to verify the identity of their clients and assess their potential risks, primarily to prevent illegal activities like money laundering, fraud, and terrorist financing. This process usually requires customers to submit personal identification documents (e.g., passport, utility bills), which are then verified by…

Network Time Protocol (NTP) is a protocol used to synchronize the clocks of computers and devices across a network. It ensures that the system clocks of multiple machines, regardless of geographic location, remain in sync with each other. This is critical for many applications, such as logging events, coordinating processes, or ensuring security mechanisms function…

The Blockchain Trilemma refers to a concept in blockchain development that suggests there is a trade-off between three key properties: decentralization, scalability, and security. According to this trilemma, it is challenging for a blockchain to fully optimize all three of these properties simultaneously. Instead, developers often have to make compromises and prioritize two at the…
