Glossary

Welcome to the NuLink Glossary, where you can find key terms and their definitions related to NuLink's Web3-based ZK Provable Data Privacy Solutions.

A

Access Control

Access Control refers to the mechanisms, such as Proxy Re-Encryption (PRE) and Attribute-Based Encryption (ABE), implemented by NuLink to regulate and manage data access.

B

Bond

Bond is the process in NuLink where a staker establishes the mapping between their staking account and a service node, such as a worker node. After staking tokens in the dashboard, the staker initiates the bonding procedure to link their worker node to their staking activities. This linkage is essential for the network to recognize the staker's contributions and allocate rewards accordingly.

Batch

A Batch in the NuLink network refers to a designated period, comprising multiple epochs. The specific length of a batch will be determined by the DAO in a late stage.

C

Claimable Deposit

Claimable Deposit represents the amount of deposit return to the staker after unstake. The staker can claim back in the staking dashboard.

Claimable Reward

Claimable Reward refers to the reward earned by a staker within the NuLink network that can be claimed.

D

DAO (Decentralized Autonomous Organization)

The Decentralized Autonomous Organization (DAO) in NuLink is a self-governing entity that plays a crucial role in determining various network parameters, including the length of epochs, batches, etc. DAO decisions shape the overall governance and evolution of the NuLink ecosystem.

E

Endpoint Encryption

Endpoint Encryption is a privacy-preserving mechanism provided by NuLink. It enables the secure encryption of sensitive data at the endpoint (i.e., on the local device such as PC and smartphone).

Epoch

An Epoch is a defined time period within a NuLink network batch. Key processes such as reward distribution and staker changes are orchestrated on an epoch-based timeline. This structured approach ensures that these activities are carried out at the conclusion of each epoch, offering an organized and predictable framework for managing NuLink network operations.

F

FHE (Fully Homomorphic Encryption)

Fully Homomorphic Encryption (FHE) is a cryptographic technique employed by NuLink to enable computations on encrypted data without the need for decryption.

L

Living Ratio

Living Ratio is a metric within the NuLink network that represents the proportion of stakers who are actively participating.

P

PRE (Proxy Re-Encryption)

Proxy Re-Encryption (PRE) is an access control mechanism used in NuLink. It allows for the secure sharing of sensitive data.

R

Reputation Score

Reputation Score is a metric in the NuLink network assesses a staker's historical contribution within a single batch. It counts the number of active epochs within a batch, considering epochs with a living ratio higher than a specified threshold (currently set to 0.8) as active. The reputation score serves as an indicator of a staker's reliability and positive engagement with the NuLink network

Reputation Score Quota

Reputation Score Quota is a measurement represents the proportion of an individual user's reputation score relative to the total user's reputation score within the NuLink network. The metric provides insights into the relative contribution of a user's reputation to the overall reputation dynamics of the NuLink ecosystem.

S

Service Bonus

Service Bonus is intended to encourage stakers based on their performance. This bonus is generated from the service fees paid by users to the system. It reflects the active and valuable participation of stakers in delivering reliable and efficient services within the NuLink ecosystem.

Stake

Stake is the process in NuLink where a staker deposits tokens into the pending pool. Tokens in the pending pool are scheduled to be counted in the staking pool starting from the next epoch. By staking, a staker commits tokens to participate in the NuLink network, securing it and becoming eligible for rewards based on the staked amount.

Staker

A Staker is an entity within the NuLink network that actively participates in staking by providing services or computational resources. Stakers contribute to the network's operations and receive rewards in return.

Staker Address

Staker Address is a unique identifier associated with a staker within the NuLink network. It serves as a reference for tracking and managing staking activities, rewards, and contributions.

Staking Amount

Staking Amount represents the quantity of tokens a staker commits to the NuLink network as part of the staking process. This amount is a key factor in determining staking rewards and incentives for the staker.

Staking Reward

Staking Reward is the reward earned by a staker within the NuLink network based on their staking activities and service performance.

U

Unbond

Unbond is the process in NuLink where a staker terminates the established mapping between their staking account and a service node, such as a worker node. By initiating the unbonding procedure, the staker discontinues the association between their staking activities and the worker node.

Unstake

Unstake is the process in NuLink where a staker moves deposited tokens from the staking pool to the pending pool. Tokens in the pending pool can be claimed back by the staker in the next epoch.

V

Valid Staking Amount

Valid Staking Amount is a dynamically adjusted quantity of tokens committed by a staker to the NuLink network as part of the staking process. It is calculated by multiplying the staking amount by the living ratio. This adjustment ensures that the staker's contribution is proportionate to the overall engagement and participation of stakers within the network..

Valid Staking Quota

Valid Staking Quota represents the percentage of the total valid staking capacity that a staker contributes to the NuLink network for a specific epoch. It is calculated by dividing the staker's valid staking amount by the total valid staking amount in that epoch. This metric provides insights into the relative contribution of an individual staker to the overall staking dynamics of the NuLink ecosystem.

W

Worker

A Worker is a participant in the NuLink network responsible for providing PRE services.

Worker Address

Worker Address is the unique identifier associated with a worker node within the NuLink network.

Z

ZKP (Zero-Knowledge Proof)

Zero-Knowledge Proof (ZKP) is a cryptographic protocol used by NuLink to prove the authenticity of information without revealing the actual data.
