Total Transaction Size sums the byte sizes of Bitcoin transactions recorded each day, in bytes. It is a daily data-volume measure, not the cumulative blockchain size or the BTC value transferred.
An increase means more transaction data was recorded that day, through more transactions, larger transactions, or both. The series reached about 456.16 million bytes on March 23, 2023, compared with a 2022 daily high of 242.93 million bytes; byte throughput can change markedly as the transaction mix changes.
Daily totals also vary with the number of blocks mined. They do not include a backlog of unconfirmed transactions and cannot on their own establish congestion. Byte totals are distinct from block weight, and transaction data totals need not equal the full storage occupied by blocks.
No. Each point covers one day's transaction data. Blockchain storage is cumulative and also includes block-level data beyond the transactions measured here.
Using decimal units, it is 456.16 MB. Dividing bytes by 1,000,000 gives decimal megabytes; binary mebibytes use a different conversion.
No. It measures recorded transaction data, while congestion concerns transactions competing to be confirmed. Compare fees, pending transactions and the day's block production for context.
