How to dump peers.dat file to a plain text file?

How to dump peers.dat file to a plain text file? Is there a simple solution to dump [ whole ] peers.dat file to a text file?

Why do we need public key as part of Witness in P2WPKH transactions?

Why do we need public key as part of Witness in P2WPKH transactions? As we want to minimize the data payload in a blockchain, which also led to concepts like SegWit, and is matter of discussion in Signature aggregation etc, I wonder why do we actually need to supply public key in order to spend? It's needless 33B of data. ScriptPubKey could look like this <HASH160> OP_CHECKSIG2 and ScriptSig <Signature>. I know this requires Softfork, but as we introduced SegWit, why wasn't this the design? Is it because mapping signature -> public key is not unambiguous? https://ift.tt/2Iy0D3b

unanswered bitcoin questions

unanswered bitcoin questions i read a lot about bitcoins and mining and nodes but there are a few questions that are still not answered, which are the following: 1-as i read when a transaction is broadcasted, at first it gets confirmed by active nodes and later goes to mempool and miners pick the ones with higher fees, so the question is when i make a transaction on a website how can i make sure that the website is broadcasting my transaction? maybe the site is holding it because it has high fee so that he can include it in his own block. 2-i noticed that nodes are becoming fewer every day , does this mean when they become less the security of bit coin or its value will decrease ? 3-in order to become a miner, do you have to be a node too? 4-btc.com has a crazy fast hash rate does it even worth it to get into mining? 5-say i want to become a miner with a chance of solving at least one block in a month, approximately how much should i invest ? and should i buy cloud space or mine on my ...
