As we have exhaustively covered, getting accurate estimates of the actual economic throughput of public blockchains is not a trivial task. Due to the existence of mixers, self-churn, privacy enhancements, spam, and change outputs (in UTXO chains), raw estimates of transactional value are often misstated by a factor of 10 or more.
An update to our ERC-20 methodology
Recently, it was brought to our attention that our figures for transaction count and transaction volume for ERC-20 tokens were quite significantly different from those of Etherscan.io. We looked in to this and realized that we were undercounting these figures – dramatically in some cases.
