Generating Enode on private ethereum blockchain?
I am currently in the process of creating a private clique proof-of-authority blockchain using geth. I currently have a problem of starting the bootnode and generating the ip (enode).
I am currently receiving this:
$ bootnode -nodekey bootnode.key INFO [11-14|11:40:58.441] New local node record seq=1 id=9d38dd0ca358d52c ip=<nil> udp=0 tcp=0
following this https://github.com/ethereum/go-ethereum/wiki/Setting-up-private-network-or-local-cluster I should be receiving something like this
I0216 09:53:08.076155 p2p/discover/udp.go:227] Listening, enode://890b6b5367ef6072455fedbd7a24ebac239d442b18c5ab9d26f58a34 9dad35ee5783a0dd543e4f454fed22db9772efe28a3ed6f21e75674ef6203e47803da682@[::]:30301
The readme does seem outdated and I cannot find anything else relating to this? Could someone link me something to explain this? Cheers
What algorithm does MetaMask use to encrypt the DEN before storing it in the local browser?
I am trying to build my own browser wallet for Ethereum. I am aware that MetaMask is a deterministic wallet. It stores its key phrase in the browser storage using localStorage (in the background since its a chrome extension). This data is encrypted using the password that's used to create a new MetaMask den.
I want to know what algorithm is MetaMask using to create a persistent browser wallet (E.g. is it AES or ECDSA?). I also want to know the exact data that is being stored (E.g. is it just the seed phrase and number of wallets generated ?)

Why does the speed of transactions depend on the speed of nodes in the Ethereum network ?
