Key Concepts
- Proportional Resource Allocation: Validators receive network resources proportional to their delegated SOL.
- Sybil Attack Resistance: Higher delegations provides increased resistance against Sybil attacks.
- Commercial Benefits: RPC infrastructure operators and validator nodes gain advantages in transaction inclusion and capacity.
Technical Implementation
The swQoS system operates on the following principles:- Packet Transmission Rights: A validator’s right to transmit packets to the epoch leader is directly proportional to their delegations.
- Priority Queueing: Transactions from larger validators receive priority in block inclusion.
Example Scenario
Consider two validators:- Validator A: 2% of staked SOL
- Validator B: 0.2% of staked SOL
- Validator A can submit up to 2% of packets to the block producer
- Validator B is limited to 0.2% of packet submissions

Transaction Weighting
In the swQoS system:- Each transaction carries a “weight” based on delegations.
- Higher-weight transactions have a greater probability of inclusion in the next block.
- Increased delegations correlates with higher quality of service and improved resilience against potential malicious activities from lower-delegation validators.
