RTD-Rollup

KRC-20 adopts Kaspa’s RTD (Real-Time Decentralization) mechanism to implement an efficient and secure Layer-2 Rollup protocol. During block production, Layer-1 miners embed KRC-20 Rollup data into Kaspa Layer-1 blocks via the payload mechanism, enabling on-chain verifiability for KRC-20 OPs and state data.

Rollup data primarily consists of checkpoint hash commitments and auxiliary metadata. Each valid KRC-20 transaction deterministically produces an independent, transaction-level checkpoint commitment. This commitment is composed of (i) the previous checkpoint, (ii) the OP header (used to anchor the OP’s Layer-1 reference data), and (iii) the KRC-20 state commitment, thereby forming a verifiable, tamper-evident chained provenance structure.

The KRC-20 Rollup protocol distributes rewards to miners who correctly submit checkpoints and satisfy the eligibility criteria. The reward schedule is computed automatically by the KRC-20 protocol and is disbursed in bridged native KAS tokens. The reward pool is funded by fees generated from KRC-20 OPs. This mechanism both sustains miner participation and further strengthens the decentralization of the Rollup process.

To qualify for Rollup rewards, the reward-receiving address (i.e., the coinbase output address) must stake a sufficient amount of bridged KAS on KRC-20. Addresses that fail to meet this requirement are considered ineligible and will not receive the corresponding Rollup reward share.

• Real-Time Decentralization: Rollup data is submitted by miners worldwide.

• Chained Commitments: Strong-consistency, transaction-granular checkpoints that are traceable, verifiable, and immutable.

• KRC-20 Incentive Mechanism: Additional miner revenue coupled with bridged-KAS staking requirements.
