So the thing that prevents the conflict aspect of double spends are nodes. How does bitcoin prevent double spending? For instance, electrum's paytomany option. Double spending is avoided through the confirmation mechanism and immutability of the blockchain. There is no qualification by the network that prevents the same bitcoin from being used in multiple, parallel (unconfirmed) transactions. Bitcoin naturally defends against this by confirming which the transaction which is included in a block first. Each bitcoin has a log of digital signatures attached to it, denoting the true path of its exchanges. If bitcoin and other cryptocurrencies continue to prevent double spending and prove to be reliable, then it is possible that hundreds of millions of people could start using them regularly. The proof of work is what allows for the irreversible aspect.
