Ethereum Versus Ardor Blockchain Growth

Ethereum blockchain grows approximately 4GB per year while Ardor is only growing 17 GB

Under the assumption that every block is full of transactions, Ethereum grows 150% faster than Ardor. To further reduce blockchain bloat, Ardor is using a blockchain pruning system. It's not necessary for every node to hold a complete copy of the transaction history, the the relevant recent transactions.
