Proof-of-authority: Proof-of-authority is a consensus mechanism used in blockchain networks where a limited number of approved nodes, or authorities, validate transactions and create new blocks. This approach emphasizes identity and reputation of validators over computational power or stake, making it faster and more energy-efficient. It is often used in private or consortium blockchains where the identities of validators are known and trusted, but it raises concerns about centralization and trust in the chosen authorities.
Proof-of-Authority (PoA): Proof-of-Authority (PoA) is a consensus mechanism used in blockchain networks where validators are pre-approved and their identities are known, contrasting with more decentralized approaches like Proof-of-Work. In PoA, trust is placed in these known entities rather than an anonymous network, leading to faster transactions and lower costs, but raising concerns about centralization and trust issues.
Proof-of-Stake: Proof-of-Stake (PoS) is a consensus mechanism used in blockchain networks that allows validators to create new blocks and confirm transactions based on the number of coins they hold and are willing to 'stake' as collateral. This system contrasts with Proof-of-Work, where validators must solve complex mathematical problems. PoS is designed to be more energy-efficient and secure, while also providing incentives for users to hold onto their coins instead of selling them.
Proof-of-stake (pos): Proof-of-stake (PoS) is a consensus mechanism used in blockchain networks to validate transactions and create new blocks. Instead of relying on miners to solve complex mathematical problems as in proof-of-work systems, PoS allows validators to create new blocks based on the number of coins they hold and are willing to 'stake' as collateral. This approach aims to improve efficiency, reduce energy consumption, and enhance security in blockchain systems.
Proof-of-Work: Proof-of-Work is a consensus mechanism used in blockchain networks where participants (miners) solve complex mathematical problems to validate transactions and create new blocks. This process ensures security and decentralization by requiring computational effort, thereby preventing malicious activities like double-spending and ensuring that all network participants agree on the current state of the blockchain.

This approach ensures that no single party can access the others' data, making it especially relevant in scenarios where privacy and confidentiality are crucial. By enabling collaboration without compromising sensitive information, SMPC plays a significant role in enhancing privacy within blockchain technologies and addressing challenges related to data security in decentralized systems.
Secure multi-party computation (MPC): Secure multi-party computation (MPC) is a cryptographic protocol that allows multiple parties to jointly compute a function over their inputs while keeping those inputs private. This means that even though the participants collaborate to get a result, none of them learn anything about the other parties' inputs. This method addresses significant privacy concerns and provides a way to perform computations in a distributed manner, ensuring security and confidentiality among the parties involved.
Sharding: Sharding is a technique used in blockchain technology to improve scalability and performance by dividing a database into smaller, more manageable pieces called shards. Each shard processes its own transactions and smart contracts, allowing for parallel processing and significantly increasing the overall throughput of the network. This approach helps address the challenges of scalability, reduces congestion, and enhances the efficiency of blockchain platforms.
Supply Chain Traceability: Supply chain traceability refers to the ability to track and verify the journey of a product through every stage of its supply chain, from raw materials to the end consumer. This process ensures transparency and accountability in the supply chain, making it easier to identify issues such as fraud, contamination, or inefficiencies. The growing demand for sustainable and ethical sourcing practices further emphasizes the importance of supply chain traceability in modern business operations.
Sustainability: Sustainability refers to the ability to meet the needs of the present without compromising the ability of future generations to meet their own needs. It encompasses environmental, social, and economic dimensions, ensuring that resources are managed responsibly and equitably. In various systems, particularly those involving technology like blockchain and cryptocurrency, sustainability is increasingly important as these systems face challenges related to energy consumption, resource depletion, and societal impacts.
