Privacy-preserving smart contracts are digital agreements that run on blockchains while keeping user data and transaction details confidential. Unlike regular smart contracts, which are transparent and visible to everyone, these use advanced cryptography to ensure sensitive information stays hidden. This allows people to use blockchain technology without exposing their personal or business details to the…

Differential Privacy in Blockchain
Differential privacy is a technique that protects the privacy of individuals in a dataset by adding mathematical noise to the data or its analysis results. In blockchain systems, this method can be used to share useful information from the blockchain without revealing sensitive details about specific users or transactions. By applying differential privacy, blockchain projects…
Proof of History
Proof of History is a cryptographic method used to create a historical record that proves an event has occurred at a specific time. It works by producing a series of hashes, each building on the previous one, making it easy to verify the sequence and timing of events. This approach allows computers in a network…
Proof of Space
Proof of Space is a method for proving that a participant has allocated a certain amount of storage space to a task or process. It is used as an alternative to proof of work in some blockchain and distributed systems, where instead of requiring computational power, participants show they have set aside disk space. This…
Blockchain and Cryptography
Blockchain is a digital system for recording transactions in a way that makes them secure, transparent, and nearly impossible to alter. Each block contains a list of transactions, and these blocks are linked together in a chain, forming a permanent record. Cryptography is the use of mathematical techniques to protect information, making sure only authorised…
Batch Auctions
Batch auctions are a way of selling or buying items where all bids and offers are collected over a set period of time. Instead of matching each buyer and seller instantly, as in continuous trading, the auction processes all orders together at once. This approach helps to create a single fair price for everyone participating…
Gasless Transactions
Gasless transactions are blockchain transactions where users do not need to pay transaction fees, commonly known as gas. Instead, a third party, such as a sponsor or a smart contract, covers the fees on the user’s behalf. This makes it easier for newcomers to use blockchain applications without needing to hold cryptocurrency for fees.
Decentralised Name Services
Decentralised Name Services are systems that allow users to register and manage human-readable names, like website addresses, using blockchain technology. These names replace complex strings such as wallet addresses or technical identifiers, making it easier for people to interact with digital services. Because the system is decentralised, no single entity controls the database, reducing the…
Bonding Curves
Bonding curves are mathematical formulas used in digital markets to set the price of a token based on its supply. As more people buy tokens, the price automatically rises according to the curve, and when tokens are sold, the price falls. This system helps automate pricing and liquidity without needing a traditional market or order…
Initial DEX Offering (IDO)
An Initial DEX Offering (IDO) is a way for new cryptocurrency projects to raise funds by selling their tokens directly on a decentralised exchange (DEX). This method allows anyone to participate in the token sale, often with fewer restrictions than traditional fundraising methods. IDOs typically offer immediate trading of tokens once the sale ends, providing…
