Direct theft

Alice deposits 100 bitcoins to Bank.Example.com. The next day, the owners of the site disappear with Alice's money.

Bitcoin bank users are vulnerable to direct theft because they don't control their own private keys.

Mining Bitcoin with pencil and paper: 0.67 hashes per day

I decided to see how practical it would be to mine Bitcoin with pencil and paper. It turns out that the SHA-256 algorithm used for mining is pretty simple and can in fact be done by hand. Not surprisingly, the process is extremely slow compared to hardware mining and is entirely impractical. But performing the algorithm manually is a good way to understand exactly how it works.

For example, to verify transaction D was added to the block , an SPV client only needs a copy of the C, AB, and EEEE hashes in addition to the merkle root ; the client doesn't need to know anything about any of the other transactions.

Scaling Bitcoin: The Great Block Size�Debate

Bitcoin has been roughly doubling each year (in terms of the number of transactions). But in its current form, the network can only support up to 7 transactions per second. Paypal does about 100 transactions per second and Visa does about 4,000 per second, so some changes will need to be made if bitcoin is to reach these levels.

Also your example is conceptually heading in the right direction, but the real success is when the sha256 hash of the header is less than the target. Example target: 00000000000001ae00000000000000 is greater than 00000000000001adf44c7d69767585 <-- this would be a valid hash. -  LamonteCristo Mar 1 '13 at 18:54

Can a Bitcoin miner generate SHA2 hashes on arbitrary data?

up vote 1 down vote

Do bitcoin miners(or some of them) accept customizable inputs and hash them in bulk(instead of accepting some more high-level instruction and do mining works automatically)?

Bitcoin miners generally take a parameter called "target" and "header" and return a nonce+overflow. I don't think it's possible to hash X times, resulting in predictable output (e.g. you want to compare...

Running a Bitcoin full node on $5 a month - Marc Bevand

In the context of the Bitcoin scaling debate, small blockers believe that if the block size limit is doubled, running a fully validating Bitcoin node will become expensive and only well-funded corporations will be able to run nodes, hence increasing centralization.

However facts and data disprove this narrative.

Here is a fact: despite blocks currently averaging 1 MB it is possible to run a full...
