Tableau de censure des pools de minage

Réponse rapide

Seulement deux pools de ce tableau ont des incidents de filtrage de transactions OBSERVÉS et datés qui ont survécu au tri des faux positifs : F2Pool (adresses sanctionnées par l'OFAC, reconnu par son fondateur en novembre 2023, re-signalé pour des blocs de décembre 2024) et OCEAN (une politique de données ouverte basée sur Knots concernant la taille des OP_RETURN et les inscriptions, à son lancement de décembre 2023 — que son propre protocole DATUM permet désormais à chaque mineur de contourner). MARA Pool a censuré des transactions sanctionnées en mai 2021 et a publiquement fait marche arrière en un mois. Tous les autres pools : aucun filtrage observé — y compris trois (Foundry, ViaBTC, SBI Crypto) signalés par b10c puis blanchis comme faux positifs de déplacement de frais. Une adresse américaine, un formulaire KYC ou le mot « conforme » dans le marketing sont un risque INFÉRÉ, pas un incident, et ce tableau ne confond jamais les deux.

La résistance à la censure en pratique : les transactions filtrées finissent quand même confirmées — juste dans le bloc de quelqu'un d'autre. Le correctif structurel, ce sont les templates contrôlés par le mineur : le DATUM d'OCEAN est en ligne aujourd'hui ; le Job Declaration de Stratum V2 ne l'est surtout pas. Si cela compte pour vous, minez là où vous construisez le template, ou exploitez votre propre pile solo.

Pool	Filtrage	Incidents (datés)	Politique OP_RETURN / données	KYC	Template	Échappatoire aujourd'hui	Juridiction	Grade
F2Pool	observed	2023-11 — b10c/miningpool-observer identified four F2Pool blocks (Sep-Oct 2023) missing OFAC-sanctioned transactions; co-founder Chun Wang acknowledged running a transaction-filtering patch and said it was disabled 'for now'. (b10c observation #8 (b10c.me/observations/08-missing-sanctioned-transactions/)) 2025-01 — b10c reported fifteen OFAC-sanctioned transactions missing from about nine F2Pool blocks mined in December 2024, concluding F2Pool might be filtering again; all were later mined by other pools. (b10c observation #13 (b10c.me/observations/13-missing-sanctioned-transactions-2024-12/))	standard-core — Has mined non-standard/oversized OP_RETURN and inscription data — its observed filtering is OFAC-address-specific, not a data policy.	no	pool-controlled	None in production.	China-origin (co-founder Chun Wang); operating entity offshore/undisclosed	A
The only pool with a founder-acknowledged sanctions filter, applied intermittently. At its hashrate share this delays rather than prevents confirmation — the filtered transactions were mined by others in later blocks.
MARA Pool	observed	2021-05 — Marathon directed its hashrate to an OFAC/AML-compliant pool and mined its first 'clean' (censored) block in early May 2021, filtering sanctioned transactions. (Marathon press release + Bitcoin Magazine, May 2021) 2021-05 — After community backlash, Marathon announced in late May 2021 it would stop filtering and move all miners to standard Bitcoin Core 0.21.1 — the reversal is the canonical precedent that public censorship costs a pool more than it earns. (CoinDesk / The Block, May 31 2021)	standard-core — Post-2021 reversal.	unknown	pool-controlled	None; MARA Pool is largely MARA's own fleet.	United States (MARA Holdings, Fort Lauderdale FL; Nasdaq: MARA)	A
Historic, self-declared OFAC censorship — publicly abandoned within about four weeks. Listed as the reversed case, not a current filterer.
OCEAN	observed	2023-12 — At launch (running Bitcoin Knots), OCEAN's default template filtered Ordinal inscriptions and rejected Samourai Whirlpool CoinJoin / BIP47 notification transactions whose 46-byte OP_RETURN exceeded the 42-byte datacarrier limit; Samourai publicly called it censorship and OCEAN acknowledged the inscription filtering. (news.bitcoin.com + atlas21.com, Dec 2023)	filters — Knots-based DEFAULT template restricts OP_RETURN size and inscriptions — a data policy, not OFAC-address filtering. Since Sep 30 2024, DATUM makes the restriction miner-overridable: each miner can build its own template.	no	miner-controlled	DATUM — live since Sep 30 2024: the miner runs the DATUM Gateway against their OWN bitcoind and builds their own block template while keeping pooled TIDES payouts. The strongest real escape hatch on any pool today.	United States (Delaware; co-founded by Luke Dashjr)	A
Non-custodial, no KYC (payout address only), coinbase-paid rewards. Its filtering is a spam/data-policy stance the pool is open about — and the only 'filtering' incident on this scorecard that the affected miner can individually override.
AntPool	none-observed	—	standard-core — Mines inscriptions and large OP_RETURN data.	no	pool-controlled	None in production; SV2 working-group member, no live miner job declaration.	China-origin (Bitmain-affiliated); operating entity offshore/undisclosed	B
b10c's 2021 Taproot observation (some pre-activation P2TR spends not mined by F2Pool and AntPool) was standardness behavior before lock-in, not sanctions filtering. No OFAC filtering observed.
Binance Pool	none-observed	—	standard-core	yes	pool-controlled	None.	Global/ambiguous (no single disclosed domicile)	C
Mining requires a KYC'd Binance account. No documented transaction-filtering incident; occasional exchange-pool empty/near-empty blocks are propagation-latency behavior, not censorship.
BitFuFu	none-observed	—	unknown	yes	pool-controlled	None (cloud-mining / hosted model).	Singapore (BitFuFu Inc., Nasdaq: FUFU)	C
Primarily a listed cloud-mining service; KYC required. No documented filtering.
Braiins Pool	none-observed	—	standard-core	no	pool-controlled	Stratum V2 transport is live (encryption, less stale work) and BraiinsOS+ ships a native SV2 client — but the SV2 Job Declaration protocol that would let a miner build its own template is not a confirmed generally-available customer option as of mid-2026. Honest status: SV2 efficiency yes, miner-side template selection not yet.	Czech Republic (Braiins Systems, Prague; formerly Slush Pool)	B
Authored the SV2 spec. Claims of full job-declaration support overstate today's practical status; treat the JD escape hatch as not yet real here.
EMCD	none-observed	—	unknown	no	pool-controlled	None documented.	Self-stated Hong Kong HQ; mixed-region infrastructure (Europe, Kazakhstan, elsewhere)	C
No KYC for basic mining (states AML monitoring). Jurisdiction is a blended self-report, not a single clean domicile.
Foundry USA	none-observed	—	standard-core — Mines standard templates including large OP_RETURN/inscription transactions; no published filtering policy.	yes	pool-controlled	None native today — FPPS, the pool builds the template; no Stratum V2 job declaration in production.	United States (Rochester, NY; Digital Currency Group subsidiary)	B
b10c's Sep-Oct 2023 sweep flagged one Foundry block missing an OFAC-sanctioned transaction but ruled it a false positive (fee-displaced), and Foundry later mined the same sanctioned addresses. Compliance risk here is INFERRED from US jurisdiction + KYC onboarding, not observed behavior.
Luxor	none-observed	—	standard-core	no	pool-controlled	None native (FPPS, pool-built template).	United States (Luxor Technology, Seattle WA)	B
US company reported to operate without mandatory miner KYC. No filtering observed; compliance risk is INFERRED from jurisdiction only.
NiceHash	none-observed	—	standard-core	tiered	pool-controlled	None for hashpower sellers — NiceHash is a marketplace: the BUYER directing the rented hashrate picks the pool and therefore the template policy.	Slovenia (NiceHash / H-BIT d.o.o.)	B
Hashrate broker rather than a classic block-building pool; KYC tiers by activity/withdrawal volume.
Poolin	none-observed	—	standard-core	no	pool-controlled	None.	China-origin (Hong Kong / Singapore registrations)	C
Greatly diminished since its 2022 withdrawal freeze; no filtering study covers current Poolin.
Public Pool	none-observed	—	standard-core — Hosted instance templates come from the project's own Bitcoin Core node.	no	miner-controlled	Self-host: fully open source with one-click Umbrel/Start9 deployment — the miner runs their OWN node and fully controls the template. The most accessible run-your-own-template path for Bitaxe/home miners.	US-based maintainer; MIT-licensed, self-hostable	B
The censorship-resistance value is in self-hosting against your own node.
SBI Crypto	none-observed	—	standard-core	unknown	pool-controlled	None documented.	Japan (SBI Crypto Co., SBI Holdings subsidiary)	B
b10c's Jan 2025 analysis attributed an SBI block's missing sanctioned transaction to block-weight reservation / fee displacement, NOT filtering. Regulated Japanese parent implies an INFERRED compliance posture only.
Solo CK (solo.ckpool.org)	none-observed	—	standard-core — Operator states the pool does not filter any transactions and uses default Bitcoin Core selection.	no	pool-controlled	Self-host: ckpool-solo source is public, so you can run your own instance against your own bitcoind for full template control. The hosted endpoint builds a Core-default, unfiltered template for you.	Operated by developer Con Kolivas (Australia)	B
No registration or KYC; solo reward model. 'Pool-controlled' is technically true of the hosted endpoint even though the rewards are solo.
SpiderPool	none-observed	—	unknown	unknown	pool-controlled	None documented.	Asia-origin (INFERRED); operating entity not clearly disclosed	C
Fast-growing FPPS pool. No filtering study covers it; the jurisdiction is inference, not a filing.
ViaBTC	none-observed	—	standard-core	no	pool-controlled	None in production.	China-origin; operating entity offshore/undisclosed	B
One flagged block in b10c's Sep-Oct 2023 sweep was concluded a false positive (transaction too young / fee-displaced); ViaBTC later mined the same sanctioned addresses.
WhitePool	none-observed	—	unknown	yes	pool-controlled	None documented.	Europe (WhiteBIT exchange; launched Aug 2024)	C
Exchange-operated FPPS pool inside a KYC'd exchange ecosystem. No filtering or template-transparency data available.
Carbon Negative	unknown	—	unknown	unknown	pool-controlled	None documented.	UNKNOWN (operating entity undisclosed)	C
Insufficient public information — recorded as unknown rather than guessed.
KuCoin Pool	unknown	—	unknown	yes	pool-controlled	None documented.	Seychelles (KuCoin exchange entity)	C
Exchange-tied pool with mandatory KYC; minor hashrate, no transparency data.
Mining Squared	unknown	—	unknown	unknown	pool-controlled	None documented.	UNKNOWN (operating entity not reliably documented)	C
Operator and jurisdiction could not be verified from primary sources — recorded as unknown.
SECPOOL	unknown	—	unknown	unknown	pool-controlled	None documented.	Asia (INFERRED); operating entity undisclosed	C
No transparency data; jurisdiction inferred only.
Ultimus	unknown	—	unknown	unknown	pool-controlled	None documented.	UNKNOWN (Asia-origin INFERRED); operating entity undisclosed	C
Self-describes as 'compliant' — a marketing claim that might imply OFAC/AML alignment (INFERRED). No incident data exists either way.
