Bitcoin mempool activity
Loading current Bitcoin data
Connecting to live sources…A view of the pending Bitcoin transaction queue waiting to be included in blocks.
What it means
The mempool is the set of valid, unconfirmed transactions known to a Bitcoin node. BitcoinNeon summarizes the queue using its total virtual size and transaction count.
Why it matters
A larger backlog can increase competition for block space, affecting fee estimates and how quickly lower-fee transactions confirm.
A larger virtual size or transaction count means more pending transaction data is competing for future block space.
A smaller queue generally means less congestion and may allow lower-fee transactions to confirm sooner.
Source & methodology
mempool.space mempool data. BitcoinNeon reads mempool.space's mempool vsize and count values, then assigns a plain-language activity label using fixed size thresholds.
