Where did you get the 100g of e-waste figure from btw? Is that, roughly speaking, the e-waste mass of storage/txn * total number of nodes?

- throwaway271818 5y agoAh, but they’re calculating e-waste in the form of specialized mining hardware (ASIC) that, at present, goes obsolete every few years. The e-waste generated this way is not an intrinsic cost of handling a transaction, since the hardware could hypothetically be reused or recycled. It seems unwise to think of it as an irreducible cost per txn, rather than a dynamic figure that would likely improve over time (especially if the carbon externality were appropriately taxed)
