Forecaster's notes

Mempool state
The mempool is active but uncongested — 38,747 transactions occupying 8.8 vMB at rock-bottom fees (median 0.1 sat/vB). Size is -22% vs 24h avg; median fee is -70% vs 24h avg. A typical weekend lull.
Fee outlook
Good window for consolidations or non-urgent traffic — paying just 1.2 sat/vB confirms in the next block.
Urgent traffic
4 recent txes moving 42.6 BTC total are paying premium fees (≥3 sat/vB). Consistent with time-sensitive settlements, exchange withdrawals, or bridge transfers — intent not confirmable from on-chain data. Examples: 8.65 BTC at 5.0 sat/vB (1m ago); 18.18 BTC at 5.0 sat/vB (51s ago); 7.00 BTC at 3.7 sat/vB (50s ago). Plus 1 more.
Composition
Of 2,083 recently-arrived classified txs, 18% are monetary and 82% are non-monetary — 7 inscriptions (0%), 1,703 OP_RETURN (82%). That's +72% vs 24h avg. Majority non-monetary — an ordinals/data-leaning window; monetary users compete with data storage for blockspace.
Value flow
3,049.8 BTC queued for movement (-66% vs 24h avg). Most pending txs are small — typical retail/wallet traffic. 3 whale txes (≥100 btc) · 3 large (10–100 btc). Largest pending: 2,482.1991 BTC at 1.1 sat/vB. By value, 96% of BTC sits in the slow (0.5–2) sat/vB tier.
Age structure
Mempool has accumulated backlog — only 2,235 of 38,747 txs are from the last 6 hours. 3,245 stuck transactions older than a week sit at minimum fee — cheap consolidations and dust waiting for a quiet block. Many will be evicted at the 14-day expiry.
Block cadence
New block #974,979 landed -335s ago, cleared 6,417 txs.

1,050.14BTC moved on by the sweeper

Dormant single-sig wallets emptied in about 25 minutes on 30 July 2026, the day Coinkite disclosed that some COLDCARD firmware generated seeds from a predictable RNG. Public reports cite 594.5 BTC from ~500 wallets; this node sees that wave plus three more destinations swept by the same actor (same ~30 sat/vB fee, coins dormant ~3 years) within nine blocks.

Linked to COLDCARD by public reports and timing; Coinkite's advisory confirms weak seeds were exploited but does not list transactions.

Dormant-wallet sweep clusters · unattributed leads, since block 945,000

Many separate wallets holding long-dormant coins (avg. age ≥ 1 year), each emptied in its own transaction into one address within a few blocks at one fee rate. A key-compromise sweep looks like this, but so does a custodian consolidating old deposit addresses. Thieves racing other bots tend to pay well above the going fee rate; clusters at the minimum rate are more likely housekeeping. Not counted in the totals above.
