Network charts/Explicit RBF Signaling

Explicit RBF Signaling

Daily share of transactions signalling replaceability under BIP 125

Short ranges plot one point per block, about one every ten minutes. Longer ranges plot one point per day, computed from every block in that day. How it is computed depends on the chart: some average, some total the day up, some are a ratio of the day's sums, and each chart says which. Either way a brief spike inside a day is smoothed away.

Key factsCalculated from the points currently plotted, so they follow the range you pick. Zooming with the slider changes only what you see, not these.

OverlaysExtra context drawn on top of the chart. Event markers are vertical lines at dated moments; a comparison series is a second set of numbers on its own axis at the right.

Event markers

Every 210,000 blocks, roughly every four years, the block subsidy halves. Fees are the other part of what a miner collects and do not halve with it. Four halvings have happened so far.

A BIP is a Bitcoin Improvement Proposal: a design document for a change to the protocol. These lines mark the dates that proposals such as SegWit and Taproot became active on the network.

Releases of Bitcoin Core, the software most nodes run. A release does not change consensus rules by itself, but it often changes what transactions a node will relay, which can show up in these charts.

Dated moments outside the protocol that moved the numbers: exchange failures, country-level bans, the first Ordinals inscriptions.

Comparison series

The BTC price in US dollars, drawn on its own axis on the right. Sampled every 4 days, which is all the source provides for the full history, so a range shorter than that cannot draw it. Price crosses six orders of magnitude, so it usually wants the logarithmic setting beside it.

The total size of the block chain on disk, growing as blocks are added. An archival node keeps every byte of it; a pruned one verifies the same blocks and then discards the old ones.

About this metric

Definition

How many transactions said, when they were sent, that they might be replaced by a higher-fee version. It is a signal in the transaction rather than a thing that happened: 67.7% of recent transactions carry it, and Bitcoin Core has allowed replacement regardless since version 28.

How it is measured

Replace-By-Fee (BIP 125) lets senders bump fees on unconfirmed transactions. A transaction signals RBF by setting at least one input's sequence number below 0xfffffffe. Higher adoption means more wallets support fee bumping, which can help users during congestion.
