The "12 word mnemonic" is basically a passphrase. Hierarchical Deterministic accounts are a number of accounts that are cryptographically related and will be deterministically created given a certain mnemonic input. The best explanation of this can be found here. This tool creates unique Hierarchical Deterministic accounts. There is another tool called Icebox which will allow you to generate account(s) on cold storage. This comment provides clarity as regards this matter. That is to say, accounts don't need to be 'created' or 'registered' on the blockchain - all possible accounts inherently exist. That same private key will never (probabilistically) be generated again.Īs outlined in the Ethereum docs, "The Ethereum blockchain tracks the state of every account, and all state transitions on the Ethereum blockchain are transfers of value and information between accounts.". You have created a random private key from which the account is derived. My initial naive thinking was: "If this new account is not transferred to the blockchain over the Internet, how will it be 'registered'".īased on the above explanation of public/private key combinations (and their relation to account addresses) hopefully you can see the answer. This is outlined by the author here.īut how can you create a wallet offline?!Īnother confusing point for me was how you can create an account without being on the Internet. This refers to a device that is not connected to the Internet.

You can download the source code and run it on an 'air locked' device to generate a wallet offline.

MyEtherWallet is wallet software written in Javascript.

So basically whilst private keys can theoretically collide, in practice they don't because of PROBABILITY !! :) Offline wallets This comment on reddit explains this extremely well. There is an answer for that too.Ī wallet generates a random private key. I was intrigued as to how one guarantees the uniqueness of Ethereum addresses. The address is also contained within the key file. Your address is the address that others use to send you Ether. How this is done is outlined in this fantastic answer. The below refers specifically to Ethereum Wallet and Parity Wallet.Īs outlined in this Stack Exchange question this key file contains your private key encrypted using a (user defined) password.įrom your private key is derived a public key and an address.

Ethereum Wallet interfaces with your running Geth node which (on macOS) stores keys in /Library/Ethereum/keystore.

In Parity (on macOS) these are stored in ~/.parity/keys.

Watch this video outlining how it works.īehind the scenes each of these wallets is working with a key file.

MetaMask.io - a wallet served as a chrom extension.

Parity Wallet - a web based wallet interface coupled with the Parity Ethereum client.

Ethereum Wallet - the wallet software created by the Ethereum foundation.

MyEtherWallet - a web based wallet written in Javascript.

In that vein, the following are Ether wallets: In cryptocurrency land a wallet tends to refer to the platform through which you interface with your Ether. You put fiat cash into you wallet, and take it out when you want to spend some. In the physical world you interface with a physical wallet. NOTE I tried to make this as beginner accessible as possible, but the engineer in me got a bit out of hand. Lets pause for a moment, and explain/outline in depth the totality of my post-resolution research. All of a sudden I was being asked to sign a request for a transaction which I hadn't initiated through the Parity Wallet UI. Having read this thread on reddit the previous day, security was at the top of my list of 'things to investigate'. Two days ago I stormed into the Parity Gitter shouting and screaming.

Double Negative (the company which I own and operate) has less on its plate, and we are considering building out web based applications that integrate with the Ethereum blockchain. I read up, felt that it was the future, and decided to invest some of my personal savings in the project (by proxy of their Ether token).įast forward a year or so and rather than simply keeping 'in the know' as regards developments in the project I decided to dive deep and try and get to grips with some of the complexities of the project. Since mid 2015 I have been aware of Ethereum. Don't tell gavofyork or tomusdrw, but two days ago I robbed myself.
