Bitcoin
Consensus mechanism
Proof-of-work (SHA-256).
Incentive mechanisms
Block subsidies and transaction fees paid to miners validating blocks on the Bitcoin network.
Table 2 — Mandatory key indicator (energy consumption)
| S.8 | Total annual energy consumption | To be published — pending compliance sign-off of quantitative figure(s) from the approved sustainability assessment. |
| S.9 | Energy consumption — sources and methodologies | Energy consumption is estimated using a top-down economic profitability model for proof-of-work networks: hardware is selected by consensus hash algorithm (SHA-256 for Bitcoin; Scrypt for Litecoin); a profitability threshold is applied from mining revenue and cost structures; network energy use is derived from hardware distribution, efficiency assumptions, and on-chain miner revenue data. Merge-mining is included where material. Geographic energy mix and GHG estimates use public grid data where node location is unknown. All figures are estimates subject to the methodology described in the identified source document. |

Table 3 — Supplementary key indicators
Required where annual network energy consumption exceeds 500,000 kWh per year.
| S.10 | Renewable energy consumption (share %) | To be published — pending compliance sign-off of quantitative figure(s) from the approved sustainability assessment. |
| S.11 | Energy intensity | To be published — pending compliance sign-off of quantitative figure(s) from the approved sustainability assessment. |
| S.12 | Scope 1 DLT GHG emissions — controlled | To be published — pending compliance sign-off of quantitative figure(s) from the approved sustainability assessment. |
| S.13 | Scope 2 DLT GHG emissions — purchased | To be published — pending compliance sign-off of quantitative figure(s) from the approved sustainability assessment. |
| S.14 | GHG intensity | To be published — pending compliance sign-off of quantitative figure(s) from the approved sustainability assessment. |
| — | Supplementary indicators — sources and methodologies | Table 3 supplementary indicators (S.10-S.14) apply where annual energy consumption exceeds 500,000 kWh. Sources and methodologies align with Table 2 and the identified MiCA sustainability source. |
