    Very nice explanation.
    However, one thing is not clear for me:
    “if the output can be consumed by two or more people at the same time”
    Multi-signature allows to own Alice and Bob the same UXTO, and only both agreement gives the ability to spend tokens. So the word “consumed” means something different?
    If Alice own 10 tokens and Bob 3, and all of the tokens are in the same account on the Ethereum blockchain, then how the blockchain can know that Bob can spend only 3 of 13 tokens?

    I don’t think the point for SPV is true. ETH also have lots of wallets with which I don’t need to download full node and still send txs.
