A bitcoin, as defined in [the whitepaper](https://bitcoin.org/bitcoin.pdf), is a chain of digital signatures. "To own 1 bitcoin" is by definition equivalent to the following: "in the history of transactions, as defined by the heaviest blockchain branch originating from the [genesis block](https://en.bitcoin.it/wiki/Genesis_block), there exist unspent transaction outputs that sum up to 1 bitcoin such that you have the private key(s) required to spend them".
