I want to fetch transactions for an address from the following api:
https://blockchain.info/address/$btc_address?format=json
The thing is understanding the json returned from the api, I don’t understand which of them are the transaction and the time when that transaction took place.
Can any one help?
Just curious how many complete implementations of the bip32 standard exist.
What is the size of the current ledger and all indices required to efficiently search through it or query it? Also, how will this size grow relative to the number of Ripple users?
Side-question: what database technology is used by rippled to store the ledger?
I would like to know how to run multiple DNS Seeds on the same node.
It seems fairly straight-forward as described in: https://github.com/sipa/bitcoin-seeder
For example, I want two DNS Seeds:
bitcoin-seed.mydomain.com
testnet-seed.mydomain.com
It seems as per the existing instructions I would either need to run multiple VMs or at the very least create new users and redirect port 53 to them. (I am not sure I can redirect port 53 to multiple users)
Is there any way that I can set this up on one VPS with Root access?
I guess the question I’m asking here is what does it take for an altcoin to be ASIC-resistant? What does it need to have?
I just learnt about the BGP attack:
http://www.wired.com/2014/08/isp-bitcoin-theft/
The attacker was able to redirect the miners to its own pool to effectively “steal” (defraud them of) their mining rewards.
I don’t know enough about the Border Gateway Protocol, but I’m wondering if this sort of an attack could be used to split the Bitcoin network itself, essentially by hijacking the node discovery process. If an attacker could hold the split for a few hours (assuming enough hash power), it could successfully execute a double-spend on its target.
Does the client use any kind of authentication with its peers?
P.S. Of course, there would have to be enough economic or political motivation to carry out such an expensive attack (such as to bring down a popular exchange and create media panic).
What exactly is the generator G in elliptical curve math? It is typically described as a point on the curve. Is this a tuple of values? What properties does it have?
