Advanced Overview

Architecture

The QuantDAO staking system operates on a mathematically elegant three-bucket architecture. The system maintains balance through the core equation α = P/S, where the appreciation ratio (α) equals the Principal Bucket (P) divided by total sQD supply (S). During each cycle, rewards from the Pending Rewards Bucket are distributed by gradually increasing this ratio, ensuring proportional distribution to all stakers. When a cycle concludes, the Excess Bucket (Next Cycle) transfers to Pending Rewards (minus a small caller bounty), restarting the process. This mechanism achieves fair distribution with O(1) gas efficiency instead of O(N) for traditional systems, as rewards compound automatically through the appreciation ratio rather than individual transfers.

The three-bucket capital segregation design isolates different token flows while maintaining system cohesion,

Principal QD Bucket (principalQDBucket) acts as the base capital reservoir that directly collateralizes the sQD token supply through a mathematically defined exchange rate. This bucket holds the sum of all user deposits and serves as the foundation for the entire staking system.
Pending Rewards QD Bucket (pendingRewardsQDBucket): functions as the active distribution mechanism during the current cycle, containing a precise quantity of QD tokens allocated for distribution over a fixed block period (~50,000 blocks). This bucket is systematically depleted at a predictable rate through the gradual adjustment of the sQD:QD exchange rate.
Excess QD Bucket (excessQDBucket): operates as a forward accumulation buffer, capturing incoming protocol revenue, trading fees, and taxes awaiting deployment in subsequent distribution cycles. This bucket effectively decouples reward accumulation from distribution.

The resulting system guarantees that each user's redeemable value (s × α) always grows proportionally to their stake, with the contract maintaining precise accounting of all QD tokens regardless of when users choose to deposit or withdraw.

Technical Advantages

The segregated bucket architecture offers several technical advantages over conventional staking designs as a means to have,

Deterministic Reward Quantification: by isolating pending rewards from new inflows, the protocol achieves precise calculus of reward rates and distribution schedules, allowing for accurate time-remaining estimations and predictable yield calculations.
Capital Efficiency Optimization: the system maintains full capital utilization while simultaneously providing liquidity partitioning that enables future protocol functionalities to be implemented without architectural refactoring.
Reentrant-Resistant Distribution: by eliminating discrete claim events and instead distributing rewards through the global exchange rate mechanism, the design circumvents common vector points for reentrancy attacks present in traditional reward-claiming systems.
Gas Optimization: the architecture significantly reduces gas costs by eliminating individual claim transactions. Instead of each user executing separate claim transactions, rewards are automatically compounded through the appreciation ratio adjustment, requiring zero user-initiated transactions.
MEV Protection Layer: the automatic distribution mechanism mitigates MEV opportunities that typically exist in protocols where claim timing can be optimized or front-run.

Innovative Aspects

The three-bucket architecture represents innovation in several key areas,

Temporal Decoupling: by separating current distribution from future accumulation, the design achieves temporal independence between reward generation and distribution, allowing for resilience against irregular revenue patterns.
Incentive Alignment Mechanism: the caller bounty system for cycle reinitialization creates a game-theoretic equilibrium where protocol participants are incentivized to maintain operational continuity in a permissionless manner.
Non-dilutive Reward Distribution: unlike staking models that mint new tokens (creating inflation), this system distributes only actual protocol revenues, maintaining token economic integrity while still offering competitive yields, and when paired with the central thesis of burns, the sQD exchange rate grows aggressively over time.
