# Fungibility #### The Basics Property of a currency whereby two units can be substituted in place of one another. Fungibility means that two units of a currency can be mutually substituted and the substituted currency is equal to another unit of the same size. For example, two $10 bills can be exchanged and they are functionally identical to any other $10 bill in circulation (although $10 bills have unique ID numbers and are therefore not completely fungible). Gold is probably a closer example of true fungibility, where any 1 oz. of gold of the same grade is worth the same as another 1 oz. of gold. Haven is fungible due to the nature of the currency which provides no way to link transactions together nor trace the history of any particular XHV. 1 XHV is functionally identical to any other 1 XHV. Fungibility is an advantage Haven has over Bitcoin and almost every other cryptocurrency, due to the privacy inherent in the Haven @blockchain and the permanently traceable nature of the Bitcoin blockchain. With Bitcoin, any BTC can be tracked by anyone back to its creation @coinbase-transaction. Therefore, if a coin has been used for an illegal purpose in the past, this history will be contained in the @blockchain in perpetuity. This lack of fungibility means that certain businesses will be obligated to avoid accepting BTC that have been previously used for purposes which are illegal, or simply run afoul of their Terms of Service. Currently some large Bitcoin companies are blocking, suspending, or closing accounts that have received Bitcoin used in online gambling or other purposes deemed unsavory by said companies. Haven has been built specifically to address the problem of traceability and non-fungibility inherent in other cryptocurrencies. By having completely private transactions Haven is truly fungible and there can be no blacklisting of certain XHV, while at the same time providing all the benefits of a secure, decentralized, permanent blockchain. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
