work in progress : https://www.speare.com/doc/4c4301e9-6b4c-47cd-887e-f16b6076a163
Technology overview
Type of blockchains
Technological constraints & functioning
Environmental Impact
Impact types
- Energy consumption (fossil energy? nuclear? …)
- Rare minerals
Impact sources
- Running the nodes + Consensus algo (PoW / PoStake / PoSpace / etC.)
- Network comunication (% of inefficiency?)
- Storage of blockchain
What measures, studies & analysis say
- For blockchains (in general) ?
- The case of Bitcoin ?
- The case of Ethereum ?
- Other coins/chains ?
Conclusions
Technical evolutions ?
What can we change ? (as users / adopters)
