The Graph: un protocole décentralisé pour l'indexation et l'interrogation des données.
Query: une requête de données. Dans le cas de The Graph, une requête est une demande de données provenant d'un subgraph qui sera traitée par un indexeur.
GraphQL : Un langage de requête pour les API et un moteur d'exécution pour répondre à ces requêtes avec vos données existantes. Le graph utilise GraphQL pour interroger les subgraphs.
Endpoint: A URL that can be used to query a subgraph. The testing endpoint for Subgraph Studio is https://api.studio.thegraph.com/query/<ID>/<SUBGRAPH_NAME>/<VERSION> and the Graph Explorer endpoint is https://gateway.thegraph.com/api/<API_KEY>/subgraphs/id/<SUBGRAPH_ID>. The Graph Explorer endpoint is used to query subgraphs on The Graph's decentralized network.
Subgraph: An open API that extracts data from a blockchain, processes it, and stores it so that it can be easily queried via GraphQL. Developers can build, deploy, and publish subgraphs to The Graph Network. Once it is indexed, the subgraph can be queried by anyone.
Indexer: Network participants that run indexing nodes to index data from blockchains and serve GraphQL queries.
Flux de revenus des indexeurs : Les indexeurs sont récompensés en GRT avec deux composantes : les remises sur les frais de requête et les récompenses d'indexation.
1. Remises sur les frais de requête : paiements des consommateurs de subgraphs pour la réponse aux requêtes sur le réseau.
2. Récompenses d'indexation : les récompenses que les indexeurs reçoivent pour l'indexation des subgraphs. Les récompenses d'indexation sont générées par l'émission annuelle de 3 % de GRT.
Indexer's Self-Stake: The amount of GRT that Indexers stake to participate in the decentralized network. The minimum is 100,000 GRT, and there is no upper limit.
Upgrade Indexer: An Indexer designed to act as a fallback for subgraph queries not serviced by other Indexers on the network. The upgrade Indexer is not competitive with other Indexers.
Delegator: Network participants who own GRT and delegate their GRT to Indexers. This allows Indexers to increase their stake in subgraphs on the network. In return, Delegators receive a portion of the Indexing Rewards that Indexers receive for processing subgraphs.
Taxe de délégation : Une taxe de 0,5 % payée par les délégués lorsqu'ils délèguent des GRT aux indexeurs. Les GRT utilisés pour payer la taxe sont brûlés.
Curator: Network participants that identify high-quality subgraphs, and signal GRT on them in exchange for curation shares. When Indexers claim query fees on a subgraph, 10% is distributed to the Curators of that subgraph. There is a positive correlation between the amount of GRT signaled and the number of Indexers indexing a subgraph.
Taxe de curation : Une taxe de 1% payée par les curateurs lorsqu'ils signalent des GRT sur des subgraphs. Le GRT utilisé pour payer la taxe est brûlé.
Data Consumer: Any application or user that queries a subgraph.
Développeur de subgraphs : un développeur qui crée et déploie un subgraph sur le réseau décentralisé de The Graph.
Subgraph Manifest: A YAML file that describes the subgraph's GraphQL schema, data sources, and other metadata. Here is an example.
Epoch: A unit of time within the network. Currently, one epoch is 6,646 blocks or approximately 1 day.
Allocation: An Indexer can allocate their total GRT stake (including Delegators' stake) towards subgraphs that have been published on The Graph's decentralized network. Allocations can have different statuses:
1. Actif : Une allocation est considérée comme active lorsqu'elle est créée sur la chaîne. Cela s'appelle ouvrir une allocation, et indique au réseau que l'indexeur indexe et sert activement les requêtes pour un subgraph particulier. Les allocations actives accumulent des récompenses d'indexation proportionnelles au signal sur le subgraph et à la quantité de GRT allouée.
2. Closed: An Indexer may claim the accrued indexing rewards on a given subgraph by submitting a recent, and valid, Proof of Indexing (POI). This is known as closing an allocation. An allocation must have been open for a minimum of one epoch before it can be closed. The maximum allocation period is 28 epochs. If an Indexer leaves an allocation open beyond 28 epochs, it is known as a stale allocation. When an allocation is in the Closed state, a Fisherman can still open a dispute to challenge an Indexer for serving false data.
Subgraph Studio : une application puissante pour créer, déployer et publier des subgraphs.
Fishermen: A role within The Graph Network held by participants who monitor the accuracy and integrity of data served by Indexers. When a Fisherman identifies a query response or a POI they believe to be incorrect, they can initiate a dispute against the Indexer. If the dispute rules in favor of the Fisherman, the Indexer is slashed by losing 2.5% of their self-stake. Of this amount, 50% is awarded to the Fisherman as a bounty for their vigilance, and the remaining 50% is removed from circulation (burned). This mechanism is designed to encourage Fishermen to help maintain the reliability of the network by ensuring that Indexers are held accountable for the data they provide.
Arbitrators: Arbitrators are network participants appointed through a governance process. The role of the Arbitrator is to decide the outcome of indexing and query disputes. Their goal is to maximize the utility and reliability of The Graph Network.
Slashing: Indexers can have their self-staked GRT slashed for providing an incorrect POI or for serving inaccurate data. The slashing percentage is a protocol parameter currently set to 2.5% of an Indexer's self-stake. 50% of the slashed GRT goes to the Fisherman that disputed the inaccurate data or incorrect POI. The other 50% is burned.
Récompenses d'indexation : les récompenses que les indexeurs reçoivent pour l'indexation des subgraphs. Les récompenses d'indexation sont distribuées en GRT.
Récompenses de délégation : Les récompenses que les délégués reçoivent pour avoir délégué des GRT aux indexeurs. Les récompenses de délégation sont distribuées dans les GRT.
.GRT : le jeton d'utilité du travail de The Graph, le GRT offre des incitations économiques aux participants du réseau pour leur contribution au réseau.
Proof of Indexing (POI): When an Indexer closes their allocation and wants to claim their accrued indexing rewards on a given subgraph, they must provide a valid and recent POI. Fishermen may dispute the POI provided by an Indexer. A dispute resolved in the Fisherman's favor will result in slashing of the Indexer.
Graph Node: Graph Node is the component that indexes subgraphs and makes the resulting data available to query via a GraphQL API. As such it is central to the Indexer stack, and correct operation of Graph Node is crucial to running a successful Indexer.
Indexer agent: The Indexer agent is part of the Indexer stack. It facilitates the Indexer's interactions on-chain, including registering on the network, managing subgraph deployments to its Graph Node(s), and managing allocations.
The Graph Client : une bibliothèque pour créer des dapps basées sur GraphQL de manière décentralisée.
Graph Explorer : Une application conçue pour que les participants au réseau puissent explorer les subgraphs et interagir avec le protocole.
Graph CLI : Un outil d'interface de ligne de commande pour construire et déployer sur The Graph.
Période de récupération : le temps restant jusqu'à ce qu'un indexeur qui a modifié ses paramètres de délégation puisse le faire à nouveau.
L2 Transfer Tools: Smart contracts and UI that enable network participants to transfer network related assets from Ethereum mainnet to Arbitrum One. Network participants can transfer delegated GRT, subgraphs, curation shares, and Indexer's self-stake.
Updating a subgraph: The process of releasing a new subgraph version with updates to the subgraph's manifest, schema, or mappings.
Migrating: The process of curation shares moving from an old version of a subgraph to a new version of a subgraph (e.g. when v0.0.1 is updated to v0.0.2).
