# Aligning Blockchain with Sustainability In our journey at Honua to champion sustainability, the choice of blockchain technology is crucial. We have selected Solana as our foundational blockchain, particularly because of its Proof of History (PoH) combined with its Proof of Stake (PoS) mechanisms. This decision reflects our commitment to environmental responsibility and technological innovation. **Proof of Stake:** Solana's PoS model marks a significant step towards eco-friendliness in the blockchain world. Unlike the energy-intensive Proof of Work (PoW) model, PoS drastically reduces the blockchain's energy consumption and carbon footprint. This aligns with our ethos at Honua, where every aspect of our operation is tuned towards minimizing environmental impact. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
