Just throwing it out there, would anyone be interested in a Bitcoin fork that has faster blocks (Let's say 10 second blocks). Block size 0.2MB. Effectively increasing block size to 12MB per 10 minute
Advantages:
* Time to 1st confirmation will be a few seconds on average, good enough for even buying coffee and actually getting a confirmation, instead of relying on completely insecure 0-conf or 3rd party service
* Much better tx/sec capacity obviously
* Better user experience overall, it will just feel fluid for all tx, anyone that has used a sub-10 sec altcoin should know the feeling. Everything is just fluid
Disadvantages:
* Potentially bigger blockchain size obviously, but that's not really a big problem unless we are doing VISA level transaction volume
* Orphans for everyone, but that's fair
The idea sounds great. But what happens if you can use Bitcoin with low transaction taxes. People will start using it at a VISA level and yes that's great for the adoption and all. But we first need to find a solution for the increasing blockchain size before making the blocks faster in my opinion.
Overall on the streets, people that know about blockchain do say the following why would I use Bitcoin to pay at the gas station or buy a coffee because the transaction costs are too high? If that barrier is gone yes more people would start using it for smaller transactions. Just that you need insane HDDs then to just store the full blockchain on.
If they can fix the scaling problem and they can get to a solution where everyone agrees on with increased security then it would be nice. But now we must just see it as digital gold at its current level.
