Decentralized Key Recovery

Decentralised key recovery is a method for helping users regain access to their digital keys, such as those used for cryptocurrencies or secure communication, without relying on a single person or organisation. Instead of trusting one central entity, the responsibility for recovering the key is shared among several trusted parties or devices. This approach makes…

Decentralized Credential Systems

Decentralised credential systems are digital methods for issuing and verifying qualifications, certificates, or proofs of identity without relying on a single central authority. Instead, these systems use distributed technologies such as blockchain to ensure credentials are secure, tamper-resistant, and easily shareable. This approach gives individuals more control over their personal information and makes it harder…

Statechain Protocols

Statechain protocols are a type of cryptographic technology designed to transfer ownership of digital assets, such as Bitcoin, without moving them on the public blockchain. Instead, control over the asset is passed between parties using a secure chain of signatures and encrypted messages, which are verified by a trusted server called a statechain entity. This…

Taproot Upgrades

Taproot upgrades are improvements made to the Bitcoin network to enhance privacy, efficiency, and flexibility. They allow complex transactions to look like simple ones, making it harder to distinguish between different types of Bitcoin spending. These upgrades also make it cheaper and easier to use advanced features like multi-signature wallets and smart contracts.

MuSig2 Protocol

MuSig2 is a cryptographic protocol that allows multiple people to create a single digital signature together. This makes it possible for a group to jointly authorise a transaction or message without revealing each person’s individual signature. MuSig2 is efficient, more private, and reduces the size of signatures compared to traditional multi-signature methods.

Aggregate Signatures

Aggregate signatures are a cryptographic technique that allows multiple digital signatures from different users to be combined into a single, compact signature. This combined signature can then be verified to confirm that each participant individually signed their specific message. The main benefit is that it saves space and improves efficiency, especially when dealing with many…
