What is the onus to prove?

In the realm of cryptocurrency and finance, the question "What is the onus to prove?" often arises in the context of disputes, legal proceedings, or even simple transactions. The onus, or burden of proof, refers to the responsibility of a party involved to present evidence in support of a claim or argument. In cryptocurrency transactions, for instance, the onus to prove ownership of digital assets or the validity of a transaction may fall on the individual or entity making the claim. In legal proceedings, the onus to prove certain facts or allegations may shift depending on the nature of the case and the applicable laws. Understanding the onus to prove is crucial in navigating the complexities of cryptocurrency and finance, as it can have significant implications for the outcome of disputes or transactions.
