My major questions have always been: where is the business value in blockchain applications? what can a blockchain app do that can't be done by non-blockchain (beyond decentralization - bc I don't think this produces much business value)?
This is really the main selling point, decentralizing consensus so no one party becomes to big to fail, or so big they are unable to be opposed which leads to tyranny.
The sad part is that the blockchain is the least interesting part of this hype. The interesting part is making all mutations of state require signed inputs which has given a really needed push to the PKC UX. Metamask is fucking amazing and interacting with applications that utilize metamask as the source of identity is so simple, something that you'd be hard pressed to find before all this hype.
Sending money without fees and delay? Have you ever tried a normal bank transfer? How long did it take?
Have you ever tried, say, nano? It literally takes seconds and 0 fees.
Here is some value.
He's not talking about Bitcoin, do people realize there's literally 1000+ projects (Most irrelevant) with some clear innovation going on. We're already way past bitcoin and PoW as the future of blockchain tech.
The delays have little to do with technology, and a lot to do with regulations and bureaucracy. Largely put in place to combat money laundering, fraud, terrorist financing, etc etc. Yes, there's some small banks that have horrible APIs and shoddy servers, but for most transfers the delays come down to things that if cryptocurrency were ever mainstreamed would be tacked onto it.
That is why it takes time to get approved on coinbase and other exchanges that try to follow the law.
There is literally no place to tack on a middleman with nano/btc. Yes it will take some rethinking of how we combat what society conceives as improper use of funds.
> There is literally no place to tack on a middleman with nano/btc.
BTC is just a widely distributed set of middlemen imposing delays and costs (both mining rewards and transaction fees are costs to everyone holding or using BTC that run from holders/users to miners.)
I plan on only accepting crypto for consulting this year, it filters out clients and I have limited time.
At some point I will exchange to USD to pay whatever I owe in taxes and to pay any vendor that does not take crypto. I imagine if I were an unscrupulous actor I would skip the tax step and avoid vendors that don't accept crypto.
Good for you. I have rent to pay, so I need to be paid in USD. That brings us back to my original question: Are the people I have to go through to exchange crypto to USD not middlemen?
Why can't you build on top of these protocols, nothing is stopping them from being underlying technology that new banks and financial institutions can be built on top of.

For less than $5,000 it is free and instantaneous in the United States (e.g. Zelle). For more, it is free and instantaneous (wire; my bank waves the fee; most charge $15 to $35).
The number one thing holding back the blockchain from becoming a proper database technology is its proponents insistence on applying it to problems that already work faster and cheaper.
In the UK we can do that without the blockchain, in many situations, thanks to the real-time payment system [0]. So for me, a normal bank transfer is free and easy, whereas every time I've tried to do something involving blockchain it's meant delays, fees, and messing around on shady-looking websites.
I take the point that in other places the norm is a lot worse and blockchain systems are producing better results, but it won't be long before banks get their act together and improve their services to match modern expectations (for fear of becoming obsolete), and then the blockchain competitive advantage is gone.
SEPA Instant Pay allows transactions of up to 15k in 10 seconds (bigger transactions fall back to the 1 day SEPA rule, I think), and some banks provide it for free. This is only relevant within the EU and associated regions, obviously.
I’m glad some people get it. Banks do zero delay and zero cost transactions between themselves already. The idea that “if only we coukd figure out where to use blockchain, everything would be FREE” is really naive. You take away a banks ability to charge for X, don’t be surprised when Y gets a new fee.
As to decentralized, there seems to be a wonderful libritarian ideal around cryptocommodities but I’m reality they are much more centralized than anyone wants to admit. There are probably 10 people that if they wanted to could absolutely demolish bitcoin.
Too much hype around all of this. Not even getting into the massive waste of power and potential.
Just about everyone that's worked in finance professionally gets it - netting, collateral calls etc all happen daily and instantaneously and have been for decades.
Having worked in computational finance the entirety of my career, I still don't totally understand how this combination of Dunning-Kruger and Libertarian leanings somehow became a thing.
The financial times while back had an interesting take: there's a structural reason why VC throws money at seemingly non-nonsensical ideas (Theranos, wireless charging etc) - many have a policy portfolio mandate to shoot for 100x returns and as such they will throw money at impossible things as part of their fiduciary duty. So, especially in the climate of free money, funding a slightly-better-widget-startup takes a backseat to things with lottery odds that may not make any sense at all.
In Canada, the gov'ment told the banks they had to offer cheap, instant transfers. Today, it's free to send money to anyone in the country and it takes minutes.
Yeah, in Australia it's currently overnight between banks (but generally instant from one account to another within a bank), and they're bringing out a new real-time payments platform over the next few months so you will be able to transfer instantly to anybody knowing only their 'pay ID', which can be a mobile number, Australian Business Number (ABN), etc.
Atomic transactions of money on one hand, and ownership on the other.
For big amounts, transfers of money are either slow (big wire transfers between banks) or unsecure (cash, how do you know if those bills are real?). Therefore either the money or ownership stays insecurely in limbo on one side.
Therefore escrow services currently provide a solution for this, or notaries. But in the end they are still not atomic, and not free either.
If both money and proof of ownership are both on blockchain, you can do a REAL atomic transaction. This could work for selling cars, houses, etc, on an international level without much fuzz.
