financial products. I challenge our innovators: devise creative solutions to prevent virtual
currency abuse.”2013, Jennifer Shasky Calvery, former FinCEN Director

● Mines and makes a payment to a third party on behalf of a customer (e.g., for-profit miners)
● Accepts value from A and delivers it to B (e.g., some wallets)
● Accepts value from A and delivers it to A at a different time or place (e.g., vaults)
…whoever
● Mines, uses or invests virtual currency for own benefit
● Provides network access services to money transmitters
● Acts as a payment processor by agreement with a seller or creditor
● Acts as intermediary between BSA-regulated institutions

• Risky “product”(no value limits, global, etc.)
• No identity & location of either S or R (FT+T rules, Sanctions) • Limited monitoring: blockchain data insufficient
(no transaction metadata + dark web)
• “Evil” smart contracts• Regulations designed for intermediaries, not P2P• Clash with privacy/confidentiality

• Global monitoring (vs. intra-company)
• Digital, global, real-time information sharing (vs. analog & after-the-fact)
• Traceability + attribution + immutability• Third-party doctrine
(privacy forfeited voluntarily; no warrants/subpoenas/MLATs)

THIEVING TECHNIQUES- AGGREGATIONS → bitcoins were moved from several addresses into
a single one - FOLDING → addresses not associated with the theft, used to “clean”
the stolen money- SPLITS → a large amount of bitcoins was split among two or more
addresses- PEELING CHAINS → small amounts were peeled off from a
succession of one-time change addressesSource: A Fistful of Bitcoins

BEHAVIORAL INDICATORS- TRANSACTION VOLUME: observe transaction volumes and pay close attention to outliers from an
expected distribution as they may stem from a major theft.
- OBFUSCATION PATTERN: aggregations, foldings (i.e., combining blacklisted transactions with clear transactions), splits and peeling chains
- FREQUENCY OF USAGE: the thief must construct his fake transactions fast, resulting in a short time span between transactions involving these coins. This motivates measuring transaction frequency to use it is an indicator of risk. Whenever frequency increases above average values, there are reasons for suspicion.
- CHANGE ADDRESSES & MULTI-INPUT TRANSACTIONS: heuristics such as the detection of change addresses or the combination of addresses from multi-input transactions, which are likely to belong to the same user, can detect connections between apparently unrelated transactions.
- COINBASE TRANSACTIONS: these transactions do not have inputs, i.e., they create new bitcoins without using up the bitcoins from other transactions.
