The ratio between propagation delay and block interval

The ratio between propagation delay and block interval

Is there a certain website or a study that gives an estimation for the ratio f = Propagation Delay/Block Interval for the Bitcoin network ? I know the Block Interval is roughly 10 minutes however, I don't know the propagation delay. I define it as the time it takes for all nodes to hear about a mined block after it's been broadcast.

QUESTION ABOUT SLOW API

QUESTION ABOUT SLOW API do you know about api requests cryptocurrency exchanges? Simple ticker request may be viewed like this: https://api.kucoin.com/v1/open/tick or like this: https://www.okex.com/api/v1/ticker.do?symbol=ltc_btc Different: in first case we get info about all currencies in one request and then pick up certain symbols and parameters, we need. Symbols are the keys of dictionaries or lists and other params are their values. In second case I should create new request for each currencies I considering. Is it neccesary? If I consider, for instance 60 symbols, and do operations with them in Python - programm bot become slow enough. One-two ticker requests are long about 30 sec - for compare, in first case - 5 sec. How can I solve this problem? Thanks. http://ift.tt/2HpiAM0

How a transaction proves its ownership of the its source, which can be one or multiple unspent output?

How a transaction proves its ownership of the its source, which can be one or multiple unspent output? I read the following from the book << Mastering Bitcoin >> "As you may notice, the transaction contains an empty scriptSig because we haven’t signed it yet. Without a signature, this transaction is meaningless, we haven’t yet proven that we own the address from which the unspent output is sourced." I am wondering how a signature can prove that this transaction owns the address from which the unspent output is sourced? https://ift.tt/2r4Ni7x
