like food and water, my posting has no intrinsic value

Offline wallets are confusing, like every other tortured metaphor in Bitcoin land.

Here's how it works: Bitcoin addresses have a private key and public key, with the public key being publicly shared to receive payment, and which is hashed from the private key. The private key is needed to actually send bitcoin transactions.

So, if you grab yourself an offline computer with the Bitcoin address generating bullshit, and hook it up to a printer that has no ability to hook up to the internet or memorize previous print jobs (:nsa:), print out the pair of keys, and slap a sticker over the private key so that nobody can ever steal it, you have an online wallet.

Now, you can send bitcoins to the public key, ask for donations to it online (because you are a bitcoiner), and look up its balance through sites like Blockchain.info, and nobody can steal the private key, unless they take the paper. Also, watch out for paper's natural enemy, a flooded basement, or just losing it in your hovel.

that's a loving load of bullshit because a truly "offline" key would have the public/private key kept completely hidden away, which effectively makes them useless because the address can't do anything without being a part of the blockchain

so once again, bitcoiners make poo poo up that isn't completely/perfectly representative of the truth

there's also a kind of conspicuous consumption element to tipping that i imagine assholes would miss, i remember reading rush limbaugh is a huge tipper. it's charity for libertarians: overpaying as a very public gesture of appreciation versus something awarded arbitrarily. where you can assure your money goes to ''your type'' of people.

you can receive money with the public address as much as you want, so you can get tips, mine, or receive money for goods and services rendered

More than just charity, it's the CoI chance to be the magnanimous patron to the poor proles who serve him. The whole tipping thing is something that goes back to aristocracy, and for some it's still an expression of power. Tipping has, in observation, not been shown to have any effect on the service a customer receives, that depends on the dedication of the staff. Still, the idea that you're the one who gets to reward the server for pleasing or displeasing is a huge thing for some people.

It's demented and hosed, but then again so is a lot of capitalism.

see, I think tipping can help in some situtations, say if you're a regular who always tips 20/25% whenever you go there. but if I go to a random restaurant, it seems pretty obvious that I wouldn't be getting better service through tipping. The tip only comes at the end of the meal, so why would a server adjust their behavior beforehand?

PS always try to tip 20% because waitstaff have a loving lovely job.

i always tip 15% because the cc machine offers that as a one button option, and we always get top notch service

Your concern is that this powerful miner has found a way to mint blocks with few transactions. The thing is that miners are free to pick and choose what transactions they want to include in a block, and at that point it is a probabilities game weather they manage to mint the block before someone else does. Bottom line is, some pool operator is trolling the blockchain, which they are free to do.

/u/BS_filter is suggesting that if block rewards get reduced to be insignificant next to the fees, then the miner might be incentivized by greed to include more transactions. That is not going to happen short term, but it sure as hell will happen naturally long term (if bitcoin doesn't crash and burn first) thanks to the reward getting halved every 4 years.

Trolls will still be trolls. It's a fact of life on the internet. Don't get your panties in a bunch over it, and don't just dismiss analysis of the problem and proposed solutions just because they don't throw the baby out with the bath water

Cryptonerds enlighten us: are there any significant chances this is a hitherto unknown vulnerability in the code relating to the transaction numbers (those get hashed for verification right?) rather than just a big miner making a big splash with processing power?

Like, could something as seemingly simple as just using powers of 2 predispose the hash to have more leading 0s?

there's no obvious advantage to only do powers of 2 transactions, the double hashing kills basically any chance of you exploiting fixed input weaknesses


one possibility is that someone has written some custom miner software and didn't manage to get the way transactions are combined into a http://en.wikipedia.org/wiki/Merkle_tree to work properly - when the number of transactions are a power of 2 the algorithm is simpler than non-powers of 2

one possibility is that this is a deliberate choice by the miner coders

another possibility is that the miners are producing blocks with non-number of 2 transactions too but since they put them together wrong they are ignored by the rest of the bitcoin network

the second possibility is what i hope for because if thats true you are only seeing a fraction of the hashing power that the mystery miner has available and when they eventually fix their code youre gonna have a 50% attack on your hands
