TX::Watch

TX::Watch is a real-time transaction visualizer for Bitcoin (BTC) and Bitcoin Cash (BCH). It turns observed transactions into a live visual stream and keeps a browser-local session ledger for activity, value, fees, and transaction signals.

The mempool is a holding area for transactions waiting to be confirmed. Each block has finite capacity: BTC accounts for block weight, while BCH uses an adaptive serialized-byte limit. If more candidate transactions are waiting than the next block can carry, only a subset is confirmed.

BTC and BCH both target a ten-minute average, not a ten-minute schedule. Proof-of-work discovery is probabilistic, so several blocks can arrive close together or a much longer gap can occur. Their difficulty algorithms respond on different schedules—BTC every 2,016 blocks and BCH after each block—but neither removes short-term variance.

Fee pressure rises when transaction demand approaches available blockspace. Miners commonly prioritize fee rate while also applying dependency, package, and local-policy rules, so this is not one strict global queue. BCH currently permits more base-layer headroom through an adaptive byte limit, while BTC uses a fixed weight limit; either network can still experience changing fees, relay policies, or delayed inclusion.

Some are small payments, tips, or application interactions. Others are token-bearing outputs, contract state, change, or minimum-value outputs, so the displayed BCH amount is not always the economic value transferred. The USD figure is also an estimate based on the market price available when TX::Watch observes the transaction.

TX::Watch subtracts all output satoshis from all input satoshis to calculate each miner fee, then sums those fees. USD totals and averages use the latest available price; a missing price is shown as unavailable. Missing input or output amounts leave fee statistics incomplete. The weighted fee rate divides total fees by total serialized bytes, not BTC virtual bytes.

They are session-local observations, not canonical network totals. Upstream disconnects, provider delays, unsupported transaction forms, parser limits, and opening the page after an event can all create gaps. USD totals depend on a separate market-price snapshot. Use a node or block explorer when complete historical accounting matters.

TX::Watch currently supports BTC and BCH because its live sources, parsers, signal classifications, and explorer links are network-specific. Adding another chain requires reliable event data and explicit support for that chain's transaction and block rules.

The data for BTC & BCH transactions and blocks is sourced from the Blockchain Socket API. Mempool and transaction fee data is sourced from the Blockchair API. SLP Token Icons are sourced from slp-token-icons.
