ZKP Fee Implications for BTCD Minting on Pg

The question asks whether the zkp payment fee in ELA would be required for every BTCD minting transaction on Pg. I will: - clarify the mechanism behind zkp payments in ELA and BTCD minting to assess how fees are applied. - evaluate whether the fee is per minting action or per batch/transaction set, considering privacy-preserving proofs. - consider protocol design, scale, and potential changes in fee policy that could affect each minting event. - identify risk factors and practical implications for users and validators. - provide a concise take and actionable guidance based on typical ZKP-integrated fee models. Translation: The user asks about whether a zero-knowledge proof (ZKP) payment fee in Elastos (ELA) would be required for every BTCD minting transaction on Pg. Expert opinion: - Without the exact Pg protocol spec, it is common for ZKP-enabled transactions to incur a fee per proof submission or per minting event, since each BTCD minting may require an independent ZKP to prove asset retention or rights without revealing sensitive data. If the ZKP is embedded in the minting step, expect a fee per mint unless the system batches proofs or amortizes costs across multiple mintings. - If the platform supports batching of ZK proofs, fees could be distributed across a batch, reducing per-mint costs but increasing the complexity of verification and potential delay. Conversely, a default model that enforces a per-mint ZKP fee would make each BTCD minting costlier, especially at high minting frequency. - Key factors influencing this include: the size and complexity of the ZKP circuit, on-chain vs. off-chain proof posting, whether fees are paid in ELA or another token, and any governance decisions on fee schedules or subsidies for privacy features. - Practical implications: users minting BTCD frequently should assess whether batching or off-peak minting reduces fees, and monitor updates from Pg on fee policy. For validators, consider how fee structures affect throughput, incentives, and security assurances around ZKP verification. Recommendation: - Monitor Pg’s official fee policy for ZKP-based BTCD minting; if per-mint fees are mandated, plan for higher cumulative costs with frequent minting. If batching is supported, evaluate optimal batch sizes to minimize per-mint cost while maintaining acceptable confirmation times. - Seek clarity on whether fees are paid in ELA or a distinct token, and whether there are any subsidy programs or tiered pricing for privacy-preserving minting. - Consider engaging with Pg governance or community channels to stay informed about any upcoming changes to ZKP fee mechanisms and potential optimization strategies.
