Lighthouse's Frequently Asked Questions (FAQ) says: Currently you cannot accept more than 684 pledges for your project. This is due to limitations in the Bitcoin protocol - the final contract that claims the pledges is a single Bitcoin transaction, a
I'm looking for specifics of Step15-17 from Redeeming a raw Tx Step By Step, which is essentially the step where the concatenated raw Tx structure is double sha256 hashed, and then signed with an ECDSA library. I've also referred to other raw transac
People often talk about SHA256 like it's a single operation, but it isn't. Rather, the input is broken up into 64-byte chunks, and then each chunk is put into a compression function. The state of the hash partway through hashing something does not de
The best Bitcoin mining hardware has evolved dramatically since 2009At first, miners used their central processing unit (CPU) to mine, but soon this wasn't fast enough and it bogged down the system resources of the host computer. Miners quickly moved
The protocol doesn't include a way to reject transactions, for a variety of reasons (the protocol doesn't know which output is real and which is change; blocks can't be changed after being mined; etc) but it is possible to do something similar. Accep
There is a known but fairly undocumented method of drastically improving SPV filtering that happens to remove this as an issue entirely, but it comes at the cost of requiring a hard fork change to Bitcoin. Traditional BIP37 SPVFor BIP37, a client set
There are a number of more complex alternatives under discussion which involve more elastic limits (instead of the hard limit which currently exists), automatically adjusted limits based on some metric in the blockchain, or some combination of both.
It could have been done that way, at the cost of increasing the amount of space it takes to store and send block headers. It seems like block header storage was a big concern for Satoshi, (there's even a section in the whitepaper about it) but it's t
When a previously unknown chain fork of at least 7 blocks length is published, how does Bitcoin Core react? It reorganizes to that chain, any transactions that were lost are returned to the nodes mempool. Would Bitcoin Core accept the chain fork if i
Be sure to take an old computer that you intend to decommission and use it "exclusively" for key generation. Don't ever use your key generation platform in a "periods processing" mode, nor save synthesized keys on the key generation platform. If a We
