Delegation

Olga Hryniuk
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.

Delegator

Vcoincheck.io
an individual or entity that delegates their stake or voting power to a stake pool operator (SPO). SPOs are selected based on the amount of ada they hold or "stake" in the network. By delegating their stake, delegators entrust the SPO with the responsibility of securing the network and validating transactions. In return, delegators can receive a portion of ...

Determinism

Olga Hryniuk
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...

Double spending

Vcoincheck.io
The act of spending the same coin/token more than once. It is a potential issue in decentralized digital payment systems where transactions are recorded on a blockchain or a similar distributed ledger. On the Cardano blockchain, double spending cannot occur due to the Extended UTXO accounting model.

ERC20 converter

Olga Hryniuk
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
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
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.

Edwards-curve Digital Signature Algorithm (EdDSA)

Olga Hryniuk
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
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.
