Blind signatures are a type of digital signature where the content of a message is hidden from the person signing it. This means someone can sign a message without knowing what it says. Blind signatures are often used to keep information private while still allowing for verification and authentication.
Non-Interactive Zero-Knowledge (NIZK) is a cryptographic method that allows one person to prove to another that they know a secret, without revealing the secret itself and without any back-and-forth communication. Unlike traditional zero-knowledge proofs that require multiple steps between the prover and verifier, NIZK proofs are completed in a single message. This makes them efficient…
Commitment schemes are cryptographic methods that allow one person to commit to a chosen value while keeping it hidden, with the option to reveal the value later. These schemes ensure that the value cannot be changed after the commitment is made, providing both secrecy and integrity. They are often used in digital protocols to prevent…
Bilinear pairing cryptography is a type of cryptography that uses special mathematical functions called bilinear pairings to enable advanced security features. These functions allow two different cryptographic elements to be combined in a way that helps create secure protocols for sharing information. It is commonly used to build systems that require secure collaboration or identity…
Elliptic Curve Digital Signatures are a type of digital signature that uses the mathematics of elliptic curves to verify the authenticity of digital messages or documents. They provide a way to prove that a message was created by a specific person, without revealing their private information. This method is popular because it offers strong security…
Decentralised marketplace protocols are sets of computer rules that allow people to trade goods or services directly with each other online, without needing a central authority or company to manage the transactions. These protocols often use blockchain technology to keep records secure and transparent, ensuring everyone can trust the process. By removing middlemen, they can…
A Distributed Hash Table, or DHT, is a system used to store and find data across many computers connected in a network. Each piece of data is assigned a unique key, and the DHT determines which computer is responsible for storing that key. This approach allows information to be spread out efficiently, so no single…
Decentralised governance models are systems where decision-making power is distributed among many participants rather than being controlled by a single authority or small group. These models often use digital platforms or technologies to allow people to propose, discuss, and vote on decisions. The aim is to make the process more transparent, inclusive, and difficult to…
Cross-chain atomic swaps are a technology that allows people to directly exchange cryptocurrencies from different blockchains without needing a central exchange or trusted third party. These swaps use special smart contracts to ensure that either both parties get what they agreed to or nothing happens at all. This process increases security and privacy, as users…
Blockchain sharding techniques are methods used to split a blockchain network into smaller, manageable pieces called shards. Each shard processes its own transactions and smart contracts, allowing the network to handle more data at once. By dividing the workload, sharding helps blockchains scale up and support more users without slowing down.
