Remember that CAs were invented as a way to solve two UX and security issues: 1. When I go to google.com, I want to be sure it's the same google.com everyone else connects to. 2. When I go to google.com many more times, I want to get t

Stroustroup tries to bend your API to his liking only because in his opinion certain syntax is "older" and more "general". Alarming quotes: "The functional (mathematical) notation is far older and more general than

Apple's Swift makes more sense with its curry feature. If you have class 'C' with method 'm' taking argument 'x', you can call that method either like c.m(x) or C.m(c, x) because C.m is automatically provi

Year-over-year bitcoin is up approx. 300% as of today. In fact, it was 90% of the time in the past 5 years up YOY, except for 5-6 months after 2011th bubble.

Bitcoin's blockchain can't handle micropayments, but blockchain is ideal for insurance deposits making micropayments as a separate protocol "economically" secure (no one wants to lose their deposit). Two use cases: 1. Mi

Logarithmic scale makes sense for everyone. If you buy at X dollars and has 100% return when the price is 2X it does not matter what X actually is. Logarithmic scale reflects relative changes which is the only interesting metric for investo

I speculate that such arbitrators would be too expensive. Who would personally go and investigate a $10 ride? I'd try something else. If you dislike the driver (or rider), rate him and your app propagates to your friends your vote. The

Actually, in Russia taxi is very lightly regulated without limited number of "medallions" like in NYC or Paris. While being in St. Petersburg this summer I ordered a taxi by phone dozens of times and it was always super-swift and

"Disrupting politely" apparently means "drivers don't make a profit therefore aren't classed as professionals". In other words, "if you would like to compete with our monopolized transportation mafia you c

Every person who takes Uber ride votes for Uber and against other taxis. If berliners are all happy with taxis, Uber wouldn't earn a penny there. But since they do and are willing to invest into challenging the ban in court, it's

This curve order limit actually introduces a small bias. You can choose a number greater than a curve order, but then it'll be taken modulo the order, so some incredibly small amount of numbers will be biased closer to zero. In practic

If the judge is really determined to put you in jail he will find CP, cocaine and unpaid taxes everywhere in your life. Law operates beyond logic and reason: only authoritative opinions and scripture interpretations matter. Ask that questio

On related note, you can think of a JPEG image as an instruction to retrieve CP from your CPU and LED screen if you will. When it comes to law, there's no logic since all laws are written and interpreted by faulty humans with some weir

Bitmessage uses similar p2p messaging as Bitcoin (all messages are broadcasted to everyone on best effort basis), similar binary protocol, Base58 encoding for addresses which are hashes of EC pubkeys and per-message proof-of-work to combat

That never happened since 2011. Consider also investing for at least a year or two: in such case you have a 99,9% chance to be in a big fat profit. Wishing to buy BTC and get rich quick is a huge gamble. Or if you are not interested in hold

I was replying to your question on how to sign transactions. Multisig is the real and the best solution for this task. Maybe I don't understand the problem with "multisig forces you to use the blockchain". If you sign a bitco

Police, fire etc. are all instances of "insurance". The only difference is that some insurance is voluntary and some is forced upon you and you have to pay. The real question is: what is the moral basis for violently making people

SSSS is worse than using OP_CHECKMULTISIG because one has to put all the secrets at once on a single machine to produce the final private key. If the machine is compromised, such key can be stolen right away. Using multisig script allows yo

Paying in Bitcoin makes a lot of sense: 1) You don't have to provide private info like CC number. 2) If you bought bitcoins at X and now they are valued at 10X you may effectively enjoy 90% discount on all purchases. All these mythical

How does it matter for seller of BTC? Once you sold it, it can be owned by anyone, how is it your concern? What's important is how many people own it. Not who exactly owns it. Today Coinbase/Bitstamp are doing good business by con

Everyone asks the same question. It does not matter if Coinbase or Expedia "sits" on BTC they receive. As long as there are people willing to sit on them, the price is going to stay the same. The price/liquidity of BTC depend

Your last statement is circular. "Network effect in value transfer" exists only when there is "network effect in seeing value in BTC units". You can't transfer value before something has value. Also, act of transfer

If the process is not designed to survive the crash than it's a more like a bug. I'd rather encourage everyone to design programs in a robust way: when they can clean up after themselves upon relaunch.

It's more like Git where the latest action is linked to all previous action + data is organized in a tree so any piece can be efficiently demonstrated as a part of the trusted whole (via a merkle branch).

Pirate bay is not Bittorrent. Bittorrent, Tor and Bitcoin are all services. But they are not centralized in hands of one person who needs to live in CH. They are distributed among thousands of small nodes which makes the entire service trul
