Solana
61.5 /100
Why this tierGreen: 60–79
Solana grades Green with a CicadaX Score of 61.5, the mean of its three lens scores. Its lens profile is uneven (8.7-pt spread), pointing to where it is strong versus where it lacks. Data completeness is 85%, so a transparency discount applies.
Solidly sustainable: low-energy, good governance, neutral-to-positive impact.
