The Elliptic Curve Digital Signature Algorithm (ECDSA) is a cryptographic algorithm used to generate digital signatures, which ensures the authenticity, integrity, and non-repudiation of digital messages or transactions. It is based on elliptic curve cryptography (ECC), making it more efficient than other signature algorithms like RSA by offering strong security with smaller key sizes. How…

Elliptic Curve Cryptography (ECC) is a form of public-key cryptography that is based on the mathematics of elliptic curves. It provides strong security while using much smaller keys compared to traditional methods like RSA. This makes ECC efficient in terms of both computation and bandwidth, which is why it’s widely used in modern cryptographic systems,…

Optimistic Rollups on Cardano are a Layer-2 scaling solution designed to improve the network’s scalability by enabling off-chain transaction execution while maintaining the security guarantees of the Layer-1 (Cardano’s main blockchain). This technology allows for more efficient transaction processing, particularly for smart contracts and decentralized applications (dApps), by shifting most of the computational work off-chain.…

Input Endorsers on Cardano are part of a planned optimization to improve the blockchain’s scalability and transaction throughput. This concept aims to separate the process of transaction validation from block production, allowing for greater parallelism and efficiency in how transactions are handled. Here’s how Input Endorsers work and their significance: In summary, Input Endorsers are…

Non-Interactive Proofs of Proof-of-Stake (NIPoPoS) are cryptographic protocols designed to allow a party (the prover) to demonstrate to another party (the verifier) that a certain blockchain is following a valid proof-of-stake (PoS) protocol without requiring interaction between the two parties or access to the entire blockchain history. NIPoPoS are particularly useful in situations where a…

KMZ Sidechains refer to a specific sidechain design proposed for the Cardano blockchain. The name “KMZ” comes from the authors of the research paper that describes them: Kiayias, Miller, and Zindros. The goal of KMZ sidechains is to enable secure and scalable communication between the main blockchain (like Cardano) and sidechains, which are independent blockchains…

Cardano uses several types of addresses within its blockchain architecture, each serving different purposes. Here are the main types of addresses in Cardano: Each of these addresses has a unique role, and their selection depends on whether you’re participating in staking, regular transactions, or smart contracts.

Byzantine Fault Tolerance (BFT) on Cardano refers to the blockchain’s ability to function correctly even when some nodes in the network behave maliciously or incorrectly, either due to bugs, network failures, or deliberate attacks. In a distributed system like Cardano, where multiple nodes work together to maintain consensus, BFT ensures that the network can tolerate…
