If Apple introduces this, it will likely require scalability higher than that of the current blockchain, which allows for roughly seven transactions per second. Peer-to-peer is definitely the way forward, but for now, banks have the infrastructure, and the customers.

There are cryptocurrencies now with more scalable architectures... I'm just counting my blessings that Apple is foolish enough to build another centralized system that is sure to be hobbled by AML requirements and misguided fraud-prevention measures. Having a centrally-mediated, proprietary cryptocurrency endorsed by Apple/Google/Amazon/Facebook is the worst thing that could happen to the cryptocurrency community right now, so I'm glad none of these companies are pursuing this opportunity yet.

This will be fixed when it's needed. To deviate from the discussion, I don't know why Bitcoin doesn't move to a faster block time. Less time to confirm a transaction, more blocks per minute, more transactions per second.

  It is very, very unlikely any major architectural tweak will happen with Bitcoin ever again. The only thing that will ever happen is maybe a few additional opcodes (to enable lightning networks perhaps) but even that will take many years. (This isn't necessarily a bad thing... although I'm certainly not a fan of this approach)

  There have already been four different proposals made to fix this (BIP 100, 101, 102, 103) and the miners shot them down. Remember that the miners profit from increased competition and tx fees on small block sizes, and they control the block size. It's more probable that banks will use some other system than ACH before bitcoin block size is ever increased.

Payment channels combined with the lightning network (https://www.youtube.com/watch?v=8zVzw912wPo https://www.youtube.com/watch?v=8zVzw912wPo) would allow Apple to create create off-chain transactions and aggregate micropayments into individual bitcoin transactions. However, unless Apple has had a secret bitcoin project going on for the past few years, it's too early to deploy something like this. Their first person-to-person product certainly wouldn't use a cryptocurrency.

  That's still not competitive to ACH or viable. If 10 million people today used off-chain, their transactions wouldn't complete until 16 days later. If 10 million people then used off chain tomorrow, their transactions wouldn't go through until 32 days later. t+22 days and you're already waiting a year to get paid in some instances.

    That's not how it works; if you checkout the presentation, you'll see it's possible for the lightning network to enable transactions that don't ever need to be broadcast to the blockchain. We're not there yet; this would require additional op codes to be added to get the full capabilities.

      Side chain transactions aren't fulfilled until they're broadcast through the blockchain. Most people and merchants do not want to be paid in arbitrary I.O.U.s that take weeks or sometimes months, which is essentially what side chain is.

        Payment channels and the lightning network aren’t side chains. And there are no IOUs; not sure where that came from.
