NMKR Glossary

A simple handbook for clear definitions and easy understanding.

#

51% Attack

A 51% attack, also known as a majority attack or majority hash power attack, occurs when a single entity or group of entities controls more than 50% of the total computational power or mining power of a blockchain network. This enables the attacker to manipulate transactions, reverse transactions, or double-spend coins, undermining the security and integrity of the network. 51% attacks are more likely to occur on smaller and less secure blockchain networks, highlighting the importance of decentralization, consensus mechanisms, and network security in preventing such attacks.

Mobile Wallets

Cardano supports mobile wallets through various software applications and platforms that allow users to securely store, manage, and transact with ADA and other digital assets on their mobile devices. These mobile wallets provide features such as address generation , transaction history, and QR code scanning, enabling users to send, receive, and monitor their cryptocurrency holdings on the go. Cardano's mobile wallet ecosystem includes both native wallets developed by the Cardano community and third-party wallets integrated with the Cardano blockchain, offering users a diverse range of options for managing their funds securely and conveniently.

Multi-Asset Tokens

Cardano supports multi-asset tokens through its native token functionality, which allows users to create and transact with custom digital assets on the Cardano blockchain. These tokens can represent various assets, including cryptocurrencies, securities, commodities, and collectibles, and can be securely traded, transferred, and programmed within smart contracts. Cardano's multi-asset token standard enables interoperability, composability, and innovation within the ecosystem, fostering the growth of token economies and decentralized applications (DApps).

#

Multi-Signature Wallet

A multi-signature wallet, also known as a multisig wallet, is a type of cryptocurrency wallet that requires multiple private keys or signatures to authorize and execute transactions. Multi-signature wallets enhance security by distributing control over funds among multiple parties, reducing the risk of single points of failure, theft, or unauthorized access. Each transaction initiated from a multi-signature wallet must be approved by a predefined number of signatories, typically set by the wallet creator, before it can be broadcasted and confirmed on the blockchain.

#

Multi-Signature Wallets

Cardano implements multi-signature wallets for security through smart contracts, cryptographic threshold schemes, and multi-party computation protocols that require multiple signatures from authorized parties to authorize and execute transactions, reducing the risk of unauthorized access, theft, or loss of funds in wallet management and transactions on the blockchain.

#

Native Token

Cardano's native token functionality allows users to create and transact with custom digital assets directly on the Cardano blockchain. These native tokens can represent various assets, including cryptocurrencies, securities, utility tokens, and non-fungible tokens (NFTs), and can be securely traded, transferred, and programmed within smart contracts. Cardano's native token standard ensures interoperability, security, and efficiency, enabling the creation of diverse token economies and decentralized applications (DApps) within the ecosystem.

#

Network Congestion

Cardano's approach to handling network congestion and spam attacks involves fee market mechanisms, transaction prioritization policies, and rate limiting controls that incentivize efficient resource allocation, discourage abusive behavior, and maintain network stability and performance under heavy loads or attack conditions.

#

Network Partition and Fault Tolerance

Cardano's approach to handling network partition and fault tolerance involves redundancy, consensus mechanisms, and adaptive protocols that mitigate the impact of node failures, network partitions, and malicious attacks, maintaining network availability, reliability, and continuity under adverse conditions or attack scenarios.

#

Network Resilience

Cardano ensures network resilience and fault tolerance through redundancy, failover mechanisms, and adaptive protocols that mitigate the impact of node failures, network partitions, and malicious attacks, maintaining availability, reliability, and continuity of service for users and applications on the blockchain.

#

Network Sustainability

Cardano ensures network sustainability through its focus on energy efficiency, resource optimization, and long-term viability. By utilizing a Proof of Stake (PoS) consensus mechanism, Cardano reduces energy consumption and carbon footprint compared to traditional Proof of Work (PoW) systems, making it more environmentally friendly and sustainable. Additionally, Cardano's treasury system and governance mechanisms enable stakeholders to allocate resources and fund initiatives that promote the growth, development, and resilience of the network over time.

#

Network Upgrades and Protocol

Cardano's approach to handling network upgrades and protocol changes involves decentralized governance processes, voting mechanisms, and stakeholder engagement mechanisms that enable users to propose, discuss, and vote on protocol upgrades, parameter changes, and ecosystem improvements through transparent, inclusive, and democratic decision-making.

#

Network Upgrades and Protocol Changes

Cardano handles network upgrades and protocol changes through a decentralized governance process known as "Cardano Improvement Proposals" (CIPs), where proposed changes are discussed, reviewed, and approved by the community through stakeholder voting and consensus mechanisms before being implemented on the blockchain.

#

Off-Chain State Channels

Cardano implements off-chain state channels for scalability through peer-to-peer communication, cryptographic commitments, and dispute resolution mechanisms that enable parties to conduct off-chain transactions, execute smart contract logic, and settle disputes off-chain, reducing on-chain congestion and latency while preserving security and trustlessness.

#

Oracles in Cardano

Oracles in Cardano are trusted sources of off-chain data that provide information to on-chain smart contracts. They act as bridges between the blockchain and the real world, supplying data such as prices, weather conditions, or events. Oracles play a crucial role in decentralized finance (DeFi) applications, enabling the execution of complex financial transactions and the creation of new financial products.

#

Ouroboros Consensus Protocol Work

Ouroboros is Cardano's innovative Proof of Stake (PoS) consensus algorithm designed to achieve decentralization, scalability, and security. It divides time into epochs, each consisting of slots where blocks are produced. Slot leaders are chosen randomly from a pool of stake-holding validators to create and validate blocks. Ouroboros ensures consensus through a process of securely aggregating transactions and reaching agreement on the valid chain.

#

Performance Metrics

Performance metrics for Cardano's blockchain include parameters such as throughput, latency, transaction confirmation times, and network scalability, which measure the efficiency, reliability, and responsiveness of the blockchain network under various conditions and workloads.

#

Permissioned Blockchain

A permissioned blockchain is a type of blockchain network where access and participation are controlled by a central authority or consortium of trusted entities. Unlike public blockchains, which are open and permissionless, permissioned blockchains require users to be authenticated and authorized before they can interact with the network. Permissioned blockchains are often used in enterprise and government applications where privacy, security, and regulatory compliance are essential.

#

Philanthropy and Social Impact

Cardano's role in philanthropy and social impact encompasses its commitment to leveraging blockchain technology for the greater good, supporting charitable initiatives, and driving positive change in communities around the world. Through partnerships with nonprofits, NGOs, and philanthropic organizations, Cardano facilitates donations, grants, and social impact projects that address critical issues such as poverty alleviation, education, healthcare, environmental conservation, and disaster relief. By harnessing the power of blockchain for social good, Cardano empowers individuals, organizations, and societies to create a more equitable, inclusive, and sustainable future for all.
