Decentralized identity

olga.hryniuk@iohk.io
A system in which users retain control over their identity using a blockchain wallet. This technology ensures data is stored securely and protects privacy rights. Users choose when and with whom they share their identity and credentials, which the requester verifies on the blockchain.

Delegation

olga.hryniuk@iohk.io
The process whereby ada owners can assign their funds using their wallets to a stake pool. This helps maintain a computer server to run a node on the Cardano network. In exchange, delegators receive a share of the pool’s total rewards. Delegating your ada is totally safe because no ada leaves the user’s wallet.

Determinism

olga.hryniuk@iohk.io
The predictability of costs for a blockchain transaction. Cardano uses deterministic pricing, which means you know how much a transaction will cost before you make it. Protocol parameters, rather than network traffic, govern pricing on Cardano, so prices remain stable and low. No fees are charged for failed transactions, which differentiates Cardano from ind...

ERC20 converter

olga.hryniuk@iohk.io
A tool that allows ERC20 tokens to be used on Cardano. Users benefit from a higher capacity of transaction processing, lower fees, and the greater security offered by the Ouroboros consensus protocol. SingularityNET’s AGIX token is the first token that users can move between Ethereum and Cardano.

EUTXO: extended unspent transaction output

olga.hryniuk@iohk.io
The accounting model used by Cardano. This is an extended version of Bitcoin’s unspent transaction output model. EUTXO brings greater security, ensures fees are predictable and can process a large number of transactions in parallel. It also supports different types of assets and smart contracts, without compromising the advantages of UTXO. EUTXO’s concurrenc...

EVM sidechain

olga.hryniuk@iohk.io
The Ethereum virtual machine (EVM) sidechain is the first sidechain built and released by IOG, with the goal of opening Cardano up to Solidity developers. The EVM sidechain allows the Solidity developer community to build DApps on a lower-fees and environmentally friendly platform that consumes far less energy than proof-of-work blockchains.

EVM: Ethereum virtual machine

Ivan Irakoze
A computing engine that functions as a decentralized computer with millions of projects that can be executed. It serves as the foundation for Ethereum's complete operating system. EVM is the component of Ethereum that handles smart contract execution and deployment.

Edwards-curve Digital Signature Algorithm (EdDSA)

olga.hryniuk@iohk.io
Cardano uses the Edwards-curve Digital Signature Algorithm (EdDSA) with elliptic curve Curve25519 as its base curve (aka. Ed25519). This gives fast signature verification and small signature sizes, which helps to improve the overall performance and security of the blockchain. Additionally, Ed25519 is designed to be resistant to certain types of cryptographic...

Elliptic Curve Cryptography (ECC)

olga.hryniuk@iohk.io
ECC is used for developing cryptographic protocols and secure applications. ECC provides the same level of security as other mechanisms while using shorter keys and signatures. Examples of elliptic curves include Standards for Efficient Cryptography (SECP) signatures such as Elliptic Curve Digital Signature Algorithm (ECDSA) and Schnorr.

Fee market

Ivan Irakoze
Cardano's fee strategy is based primarily on market demand rather than the actual supply. Research continues to be done on how Cardano can evolve to offer a fair structure of fee tiers that provides the best balance between managing demand and maintaining reasonable costs. Ultimately, the Cardano community will vote on whether or not to implement this tiered...

Formal verification

olga.hryniuk@iohk.io
The process of checking whether system design and the underlying algorithms are correct and satisfy the given requirements and properties. It is based on the formal methods of mathematics and is an integral part of IOG research. The core parts of Cardano are written in Haskell.

Fungible token

olga.hryniuk@iohk.io
A token that is identical to many others and can be traded is fungible. For example, one ada is the same as all others and so is fungible. Shares in a company, gold bars, and US dollars, for example, are all fungible. Cryptos are usually fungible, but there are also unique, non-fungible tokens (NFTs).

Game theory

olga.hryniuk@iohk.io
The study of logical decision-making made by players within the defined parameters of a system. Game theory provides mathematical frameworks for predicting interactions between people in a system, where they are all looking out for their best interests. Cardano uses game theory to help avoid economic attacks on the network.
