Dynamic Data Rate
Adjustment/ DRA
A self-regulating OP_RETURN policy for Bitcoin. DRA replaces arbitrary data carrier limits with a deterministic, market-responsive mechanism — adapting blockspace capacity to actual on-chain demand.

/ design principles
01
Deterministic
Adjustment is computed from on-chain data alone. No oracles, no governance committees, no off-protocol inputs.
02
Market-responsive
Capacity follows demand the way difficulty follows hashrate — measured per epoch, clamped to safe bounds.
03
Manipulation-resistant
Logarithmic damping plus min/max ratio clamps neutralize spam and starvation attacks.
04
Backwards-compatible
DRA replaces only the static datacarrier policy. Consensus rules remain untouched.
/ the mechanism
One equation.
Zero arbitrary constants.
Every epoch, DRA observes the median OP_RETURN payload across the last N blocks and computes a damped log adjustment. The result is clamped between L_min and L_max. The protocol — not a developer — sets the next limit.
