Sustainability indicators
MLRCOIN-O runs on the Solana network (Proof of Stake). The indicators below are published pursuant to MiCA Article 66 and the regulatory technical standards under Article 62(5) of Regulation (EU) 2023/1114.
Last updated: April 2026 · Next scheduled review: December 2027 · Status: not independently assured (Scope 1–3 audit planned within 18 months of commercial launch, whitepaper §3.7.7).
Consensus mechanism
Proof of Stake (PoS)
No Proof-of-Work mining. Validators selected by stake, not computational competition.
Annual network energy consumption
≈ 8.5 GWh / year
Solana network 2024 (Solana Foundation + Crypto Carbon Ratings Institute).
Estimated per-transaction energy
< 0.01 kWh
Per-transaction allocation derived from the network total; sensitive to load and transaction complexity.
Annual network CO₂e emissions
≈ 2,670 t CO₂e
Geo-weighted validator electricity mix. Solana Foundation public data.
Estimated Trace & Anchor footprint
< 0.5 t CO₂e / year
Projected from expected anchoring volume and the per-transaction allocation.
Renewable energy share (validators)
Significant (network-level)
Source: Solana Foundation validator mix; DMMF does not control this parameter.
Methodology
Indicators follow the IPCC-aligned GHG Protocol Scope 1–3 framework, with ADEME factors and ISO 14064 guidance for carbon quantification. Network-level figures are sourced from the Solana Foundation and the Crypto Carbon Ratings Institute (CCRI) PoS Benchmark Study 2023/2024. Per-transaction figures use a simple volumetric allocation and are sensitive to network load, transaction complexity, and validator geography.
DMMF does not claim carbon neutrality for the Trace & Anchor service or MLRCOIN-O. Figures will be revisited at least annually and independently verified within 18 months of commercial launch.
Mitigation commitments (whitepaper §3.7.7)
- Prioritise ISO 14001–certified (or equivalent) data-centre hosting for the operational layer.
- Optimise Merkle-tree aggregation to reduce on-chain transactions per anchoring operation.
- Evaluate lower-impact blockchain alternatives if the environmental profile of Solana changes materially.
- Publish an updated carbon-footprint estimate by December 2027.
- Commission an independent verification of the carbon accounting (ISO 14064) within 18 months of commercial launch.
Limitations
- Data rely on modelling and voluntary disclosures; no full life-cycle analysis has been performed.
- Indirect effects (e.g. validator hardware manufacturing) are not fully included.
- Sectoral methodology is not yet fully standardised.
- Figures are estimates; they are not a contractual commitment of performance.
