Token design, not a live asset
PlannedThis page describes a target architecture. BCGOLD is not currently presented as a liquid, backed, or externally finalized token, and no purchase or return claim is made.
The BCGOLD
Index Token
A proposed index-token architecture for representing independently verified blue-carbon inventory after the required registry, custody, and chain controls exist.
Target Architecture.
Verified Before Issuance.
The proposed BCGOLD design explores how independently verified registry inventory might later be represented through controlled smart contracts. It is not currently a liquid asset or an ownership claim.
The target design would admit independently verified and retired registry inventory under an approved custody and accounting policy. That backing relationship is not live during shadow mode.
This makes blue carbon accessible to individuals, brands, DAOs, and institutions — without needing to manage individual project positions or navigate the Verra registry directly.
Diversified Across Projects
The pool holds credits from multiple verified mangrove projects across different geographies, reducing single-project risk.
Verified-backing policy required
Any future issuance must be constrained by independently verified inventory, custody evidence, and reconciliation controls.
Composition Fully Transparent
Pool ratio snapshots are published on every composition change. Anyone can see exactly what backs each token at any moment.
Community Governed
Token holders vote on pool decisions — which projects to admit, ratio adjustments, and platform parameters. Governance weight = token balance.
From Contribution to Token
The target lifecycle has five controlled stages. External verification and permanent chain records are future acceptance requirements, not current outcomes.
Contribute to a Tranche
You contribute to a funding tranche for a specific mangrove project. Funds go directly to project developers for restoration work.
Instrument types: Grant, Revenue Share, Debt. Your contribution is recorded in the BCGReceipt contract.
Receive a Receipt → Claim a Pack
Your contribution issues a Regeneration Receipt. After the project's first Verra audit, you claim your BCGPack — a hectare-denominated position.
BCGPack is an ERC-1155 token representing your fractional hectare entitlement after audit verification.
Credits Retired on Verra
When audit milestones are met, BCG retires verified credits on the Verra registry. Retirement is permanently recorded with beneficiary attribution.
Each retirement links to a Verra serial number, beneficiary name, and Arbitrum transaction hash.
Pack Deposited into Pool
You deposit your BCGPack into the BCG pool. The pool composition ratio is updated and your pack is accounted for in the aggregate.
Pool ratio snapshots are published publicly. The BCGPool contract manages all deposits and ratio tracking.
Receive BCGOLD Index Token
The BCGIndex contract mints BCGOLD tokens proportional to your pool deposit. You now hold a fungible, transferable position in the diversified pool.
BCGOLD is an ERC-20 token on Arbitrum. Token balance = governance weight = pool position.
How the Pool Works
Ratio-Based Composition
The pool tracks the ratio of each project's packs to total pool size. Ratios update on every deposit and are published as public snapshots.
Multi-Project Diversification
The pool accepts packs from multiple verified projects. This diversifies geography, methodology, and audit timelines — reducing concentration risk.
Governance-Controlled Admissions
New projects enter the pool through governance votes. Token holders decide which projects meet quality thresholds — preventing greenwashing at the pool level.
Traditional Credits vs. BCGOLD
Proposed On-Chain Stack
These contracts describe the target architecture. Deployment, roles, bytecode, and transaction finality still require independent verification.
Issues participation receipts to contributors. Stores tranche reference, amount, and timestamp.
Hectare-denominated pack issued after first audit. Represents verified project position.
Aggregates packs from multiple projects. Tracks ratios and manages composition snapshots.
Mints the BCGOLD fungible token proportional to pool deposits. Manages redemption.
Manages credit retirement events. Links to Verra registry references and logs on-chain proof.
Anchors external Verra registry data on-chain. Provides verifiable references for audit milestones.
Who Holds BCGOLD?
Individual Contributors
Anyone who wants permanent, verifiable proof of funding nature restoration — beyond a donation receipt.
