What does 1 HydroCoin represent?

1 HydroCoin represents 1 verified gallon of stormwater infiltrated into the subsurface. Each unit is issued only after physical infiltration has been measured in the field, reviewed by a licensed engineer, and attested by an independent CPA. No credits are created based on modeled estimates or design capacity alone.

What blockchain does HydroCoin use?

HydroCoin issues and retires tokens on the XRP Ledger (XRPL) using Multi-Purpose Token (MPT) technology, providing an immutable, auditable record of every verified gallon issued and retired.

Who verifies HydroCoin credits?

Every HydroCoin credit requires dual professional verification: a licensed engineer reviews the measurement methodology and calculated volumes, and an independent CPA attests to the recorded quantities. Both approvals must be completed before any tokens are issued.

Q: Is HydroCoin affiliated with any hydrogen, fuel cell, or clean-energy token project?

No. HydroCoin (hydrocoin.com) is not affiliated with any hydrogen fuel cell, clean-energy cryptocurrency, or unrelated token project that may share a similar name. This HydroCoin is a verified water-performance accounting platform representing measured stormwater infiltration — issued only after real field measurement, professional engineering review, and independent CPA attestation on the XRP Ledger.

Q: What is the HydroCoin MRV framework?

MRV stands for Measurement, Reporting, and Verification. The HydroCoin MRV framework is a standardized methodology for calculating, documenting, and certifying stormwater infiltration volumes. It requires field sensor data, licensed engineer review, and independent CPA attestation before any water credits are issued.

Q: What is the two-token architecture described in the HydroCoin white paper?

HydroCoin uses two token types on the XRP Ledger: HydroCoin (HC) represents verified gallons of infiltrated stormwater and is the primary water credit unit; HydroSite (HS) represents proportional economic interest in a specific site's verified water performance. Both use Multi-Purpose Token (MPT) technology on XRPL.

The technical foundation for tokenizing verified stormwater infiltration. 1 HydroCoin = 1 verified gallon of infiltrated stormwater, measured in the field, verified by licensed engineers and CPAs, and recorded on the XRP Ledger.

01 — Executive Summary

HydroCoin delivers evidence-based infrastructure for stormwater infiltration through a standardized system for measuring, verifying, and recording performance. Each HydroCoin represents one verified gallon of stormwater infiltrated into the subsurface — issued only after physical infiltration has been measured, reviewed by a licensed engineer, and attested by an independent CPA. No tokens are created prior to verification.

02 — The Problem: The Measurement Gap in Water Management

Water management authorities carefully measure withdrawals from rivers, reservoirs, and aquifers, but not what we put back. Without consistent, verified data on stormwater infiltration performance, communities, regulators, and investors cannot reliably evaluate whether infrastructure investments are delivering their intended hydrologic outcomes.

03 — The Solution

HydroCoin provides the measurement and verification infrastructure needed to standardize stormwater infiltration data at scale, combining field monitoring, independent professional verification, and permanent on-chain recordkeeping to produce auditable, issuable units of verified water performance.

04 — Technical Basis for Infiltration Measurement

Stormwater infiltration is governed by well-understood hydrologic principles. Measurement methods include direct sensor monitoring of subsurface water levels, correlation with rainfall and evapotranspiration data, and site-specific engineering analysis based on known soil and basin characteristics.

05 — MRV Framework

The HydroCoin Measurement, Reporting, and Verification (MRV) framework establishes a standardized methodology for calculating, documenting, and certifying stormwater infiltration volumes. It requires dual professional approval — a licensed engineer and an independent CPA — before any credits are issued.

06 — Two-Token Architecture

HydroCoin uses a two-token structure on the XRP Ledger: HydroCoin (HC) represents verified gallons and is the primary water credit unit; HydroSite (HS) represents proportional economic interest in a specific site's verified performance. Both use Multi-Purpose Token (MPT) technology on XRPL.

07 — Token Issuance & Markets

HydroCoin units are issued in batches after each completed verification cycle, covering site enrollment, data collection, engineering review, CPA attestation, fingerprint generation, and on-chain recording. No tokens are created prior to verification.

08 — Technology Architecture

The HydroCoin platform combines IoT sensor infrastructure, a cloud-based MRV data platform, a dual-approval verification workflow, a cryptographic fingerprinting control system, and XRPL-native token issuance and retirement.

09 — Regulatory Positioning

HydroCoin tokens function as digital records representing verified environmental performance measurements. They do not represent ownership of water resources, groundwater rights, or entitlements to extract water. The platform is designed to align with emerging stormwater credit markets and environmental compliance frameworks.

10 — Pilot Program

Active pilot sites in California are currently measuring, verifying, and recording stormwater infiltration data through the HydroCoin MRV platform, validating the full verification pipeline from field measurement to on-chain issuance.
