How Bitcoin transactions are tracked
ForkLog 17 05.09.2019

How Bitcoin transactions are tracked

Bitcoin addresses are alphanumeric and pseudonymous, but every transaction is recorded openly, making activity traceable. Block explorers let anyone view balances, TXIDs and flows, while privacy tools such as CoinJoin provide only partial cover. For deeper, faster work, firms including Chainalysis, Bitfury’s Crystal and Elliptic sell analytics that link addresses, visualise flows and flag risks for exchanges and law enforcement.

What is a zero-knowledge proof?

A zero-knowledge proof is a cryptographic protocol that lets a prover convince a verifier that a statement is true without revealing any additional information about it. The notion was first proposed by MIT researchers Shafi Goldwasser, Silvio Micali and Charles Rackoff in the 1985 paper The Knowledge Complexity of Interactive Proof Systems.

How to choose a multicurrency wallet?

1 Why use a multicurrency wallet? Altcoins are gaining ground. The market capitalisation of altcoins has long outpaced bitcoin’s, as seen in the steadily declining dominance index of the first cryptocurrency. There is a vast array of altcoins, some already above $1bn in capitalisation. Many are attractive not only for their technology but also for portfolio diversification. That raises a simple question: where best to store different digital assets?
