Note for those surprised by the price tag and talking about whales: this is not like your typical in-game purchase like a special sword, unique mount, or even skins in CS:GO. These tokens implement core gameplay functionality that other pla

Assuming this is an honest question and not a lame attempt at a gotcha: as more people switch to a vegan diet we will gradually stop breeding them in the first place, so there are no animals for something to "happen to."

Good points, thanks. Followup question: how does a node coming online know not to trust China's (longer, censoring) chain? It wasn't online to have the transaction in its mempool, so it doesn't know to check for it in the lon

You are mostly correct. Except only your Bitcoin client sees the checksum/address, the raw transaction has just the pubkey hash encoded in the address. So there is no checksum for other nodes to check. If you accidentally crafted a tra

This requires colluding with a miner, since nodes will reject a transaction that spends the same output as a transaction they've already seen. For a small payment like a coffee, it should be enough to check that the transaction has a r

You make it sound like ether can only be used to pay for gas. It can also be transferred to another account in a transaction, it's the native currency for making payments. It will also be required for staking.

His point is some of the cheapest energy in the world is renewable (like hydroelectric energy in China), which is what Bitcoin is using. Bitcoin mining can take place virtually anywhere in the world so it can be done where energy is already

It'd be funny if the puzzle was to count graves. Then you would answer 20. Either there are 20 and you're right, or there are only 18 so the caretaker digs 2 more for you and your friend, so you become right.

Every Ethereum block contains a timestamp which smart contracts can read, so it's trivial to write code that only allows withdrawals in 1 month intervals. There's no way to revoke a transaction but you could implement a hold so ET

That makes sense. It wasn't clear from the paper since they talk about how Ether is "transferred or traded" and comparing it to algo trading.

With a layer 2 protocol like lightning network, we can have individual transactions be fast and cheap, and only the net settlement of a payment channel on the blockchain slow and expensive. Which is okay because it would happen infrequently
