Yet, in general, more valuable, thus increasing in usefulness over time. 1 bitcoin in 2018 is objectively more useful than a 2010 bitcoin, as it has more buying power.
So I would argue that any deflationary cryptocurrency will more likely be more useful over time as it has increased buying power. (But not necessarily value!)
Its a really nice idea, but will the cost not be passed on to the consumer in the form of inflated health insurance premiums? The health industry already stupidly too expensive in the US. Is having Uber suckling on the heath insurance teat a good thing?
one thing, if you were talking keys of length 2048, your talking RSA, and to break it you are applying GNFS, not trying all the numbers up to 2^2048.
2^2048 is so astronomically large a number it has no universe sized meaning, its likely way way more than any discrete chunking you can do of stuff in the whole universe.
Something like 2^128 or 2^256 are more common 'brute' force type numbers, which would correspond to trying every key in a symmetric cipher like AES or a public key signature in ECDSA
2^256 is similarly quite large, but we can practically estimate this to be about the number of atoms in tens of thousands of galaxies.
Its good that Riot gets money, but its incredibly damning for Status, an ICO that was meant to produce its own chat platform. This shows status has no technical ability of their own, and has to ride on existing open source products.
The status investors paid to build a new platform, and the team is unable to deliver this.
By paying an existing open source project, yes we all win, but that is not what people (not myself, are you crazy... lol) paid for.
Very cool! One bit of feedback its a pain to have to whitelist all the IP addresses for the game server. Can you associate a DNS and connect by name, this will make it easier with selective js filtering by domain?
Not exactly because bitcoin only supports a few simple transaction types -- Pay to Public Key, Pay to Public Key Hash ('standard tx'), Pay to Script Hash, Pay to Public Key Witness Hash, Pay to Script Witness Hash.
These are only serial dependent -- ie: A pays B, B pays C. You cannot reorder and still remain valid.
The security of the standard tx is the strength of the public key hash function RIPEMD-160. The security of Pay to Script Hash is finding a valid SHA256 collision with OPCODES.
The witness variants are a new tx format that uses less space (aka segwit).
The attack is simply a Denial of service, an attacker can block a tx. So if A pays B was never included in a block, B could never pay C.
This would only apply to solo-mined block rewards. If you use a mining pool, there is a coin trail through the pool. The pool likely has the IP address records of your miners and can link these to your payout transaction.
Mined coin is only just a little less traceable than exchange purchased coin.
