Simple Summary
Priming Fuse for mass business and consumer adoption requires that the infrastructure on top of the Fuse Network blockchain become more robust and decentralized. The Fuse Network blockchain must also change and offload most transactions to the execution layer.
A crucial function in this change is the introduction of Power Validators (PVs). The value proposition for PVs is predicated on the fee structure from which PVs stand to benefit.
This Fuse Request for Comments (FRC) introduces the new and improved payment flow of the Fuse Network and the entities that make the magic happen. Accordingly, this FRC requests feedback on the reward method of PV.

What functions and services will PVs perform?
PVs will perform several functions and services on the Fuse Network. These functions and services will be introduced in multiple phases.
Phase I: Relaying Service
Simply put: Relaying means bundling several gasless user operations into one transaction. Such user operations may include transaction abstractions, recurring payments, and other complex operations.
The Relay service is the inaugural service available for Power Validators to operate, and it has been instrumental in the growth of businesses on the Fuse network. This service facilitated gasless transactions for over 180,000 unique users and has been the backbone of this growth.
Permitting PVs to operate the Relay service will significantly enhance its robustness and decentralization, ultimately promoting a thriving Fuse ecosystem. In addition, PVs performing the Relay service will receive rewards through operators’ fees.
Phase II and Beyond: Identity, Indexing, Oracles, and Bridges:
In Phase 2 and beyond, we aim to decentralize most of the functionality of the Fuse Stack that does not require centralized middleware.
In addition, to relay services, PVs’ service will also include the following:
- User Identity - Upon user verification, the user will receive a DID as a Soul Bound Token (SBT), utilized to identify them on-chain. Metadata and verifiable credentials can be associated with their DID.
- Indexing - Indexing the Fuse Network and providing a user-friendly API for querying assets and wallets.
- Oracles - Running oracle nodes to provide price and other data feeds necessary for payment applications.
- Bridges - Implementation and operation of bridges between the Fuse network and other blockchain networks. The inclusion of bridges as part of the Power Validators service will further decentralize the Fuse network and promote its integration with different blockchain ecosystems.
Evaluating PVs and Rewarding them
The objective is to create a fault-tolerant system enabling high-quality service and a failover architecture. An algorithm to rate and verify the service quality per service needs to be defined. This algorithm can be used for PVs’ reputation.
We need to consider that evaluating one service is more complex than the other. For example, evaluating the Quality of Service (QoS) for the relayer service is more accessible based on on-chain data. On the other hand, the QoS of an API service has multiple parameters, such as response time failure rate.
PVs’ Service NFT: Due to the difficulty of evaluating each service, we propose rewarding each PV with an NFT representing their reputation and services. For example, a registered PV will receive a unique PV NFT. For each service the PV provides, they will be rewarded with a Service NFT (relaying NFT).
Why NFTs? This will assist Operators in choosing between different PVs and provide a transparent signal to the community.
Can PVs trade their NFTs? Yes, under several conditions. PVs wishing to discontinue their operations will be able to trade their NFTs.
