The MyCrypto desktop application is part of an older version of MyCrypto that is not actively maintained. You can find the latest version of MyCrypto on mycrypto.

MyCrypto does not allow you to use the web application to access your keystore file. Instead, you have to download the MyCrypto desktop app. A more detailed explanation on why we decided for this change can be found here. Follow our guide on running MyCrypto offline and locally.

Find your account address, next to a colorful, circular icon. This icon visually represents your address. Source: Jennicide 1. Get yourself a hardware wallet. Both are…. When you move them, you are sending them from one address on the blockchain to another. These are simply…. The following assumes you are not using a hardware wallet. If you look inside that file, you will only see your encrypted key, never the unencrypted key, and some other metadata about the key.

Geth does not support storing these private keys unencrypted. When you want to use that key to create a transaction using Geth, you will need to enter the passphrase you created so Geth can decrypt your private key in that file. The genesis file determines two things: what will take place in the genesis block , or the first block of your blockchain, and also the configuration rules your blockchain will follow.

I wrote a detailed writeup about how it works and every field in the genesis. Store the following into a genesis. We will use this for our private blockchain:. Note : Remember the address that creating the new account gave you? This is us telling Geth we want the first block in our blockchain to give billion ether to that address. We have the power to decide who starts out with what. Read my other post on the genesis state file to understand all these fields. In our genesis. This will be quick for us.

Just as the mainnet Ethereum blockchain resides on multiple computers, we will simulate having multiple computers storing our blockchain. We will create two nodes , which act like two different computers hosting and interacting with the same blockchain. Any node that wants to interact with a blockchain will want to store the blockchain on their computer somewhere it can be too large to keep in memory.

Using the —datadir flag, we specifiy where we want to store the blockchain data as we create it and it continues to grow. We will also use two different datadir directories so each node has a separate place to store their local copy of our blockchain. As mentioned, the three major operating systems by default store their blockchains in the following locations:. This assumes the genesis. Now that we have the first block written and our configuration variables set, we can launch the geth console to interact with the blockchain from our first node.

The networkid here has to match the chainID we set in the genesis. Finally, port is the port number our node will communicate with other peers over. Once you run that command, you should see a message Welcome to the Geth JavaScript console! Now, open another tab in Terminal. Notice that the datadir corresponds to the directory where we are storing the blockchain for our second node LocalNode2 and that we changed port to so our two nodes are not colliding on the same port.

From node 1, run personal. We created a wallet at the beginning of this tutorial, and then specified in the genesis. Copying that file over will give our node access to that wallet file:. Alternatively, when we launched the Geth console, we could have explicitly used the --keystore flag to tell Geth where our wallet files were. After copying over the file, go back to Node 1 and run personal. As mentioned, we allocated some ether to this wallet in the genesis block via our genesis.

This genesis block we created recognizes the wallet we control as the owner of billion ether on this private chain. Good luck! Nodes 1 and 2 have the same genesis state files and configurations, so if they could communicate with one-another, they would build on the same blockchain. Currently, entering net.

Ethereum, like many blockchain-based ecosystems, is fundamentally a decentralized technology. The protocol was designed to place little to no trust in 3rd parties like cloud providers, certificate authorities, or DNS. The blockchain that underlies Ethereum is replicated on every node in the network so that the loss of any particular node or subset of nodes is not impactful.

The fundamental innovation of blockchain is how distributed consensus is achieved without trust. And while there are endless debates about the efficiency costs of this trustless model or the overall utility of blockchain, I am more interested in the practical ramifications of this decentralized architecture. The foundation of all blockchain ecosystems—the "crypto" in the currency—is the system known as public key cryptography.

And while the public portion of a key pair may be disseminated in a decentralized manner, the private key is a fundamentally centralized concept. This fact has caused a bit of an impedance mismatch: it often feels like the centralized nature of private keys is an afterthought in the design of many blockchain systems—including Ethereum.

Wallets often feel like awkward sidecars to the protocol; and, the security and usability of private key management tools for Ethereum and blockchains in general are often lacking. This is especially true within an enterprise: try to imagine a large company using a laptop for the keys to all its accounts. Private key management is the first problem that any blockchain consumer needs to solve.

Vault can help. And since Vault can scale from a single laptop to a highly available, globally replicated data center, it can be used as a personal wallet or as an enabler of enterprise blockchain use. Vault's design allows it to broker many forms of authentication with many forms of credentialing.

Another benefit of using Vault as a platform for an Ethereum Wallet is that we get all the benefits of a hierarchical deterministic wallet without the risk - with this Vault plugin, I can very quickly and easily create many Ethereum accounts based on independently derived private keys. The Vault Ethereum plugin is an implementation of a secret backend.

This plugin provides many of the capabilities of an Ethereum wallet. It supports public and private chains. It can support smart contract continuous development practices by providing mechanisms to deploy smart contracts. It enables you to sign and verify signatures on arbitrary data. And, of course, you can send ETH. Some of the functionality creating accounts, signing and verifying can happen without needing access to an Ethereum Node. Other functionality deploying contracts and sending transactions will require access to the Ethereum RPC interface.

When you enable TLS, authentication to Vault is secure and no credentials or key material are leaked when signing transactions. This means that Vault can live on a different machine than your laptop— something you typically can't do with RPC-based wallets.

To demonstrate the power of using Vault as a platform for blockchain wallets, let's use the Vault Ethereum plugin to build an MFA-enabled Ethereum desktop wallet. To keep this exercise focused on this use case, I will make a few assumptions:. If these assumptions prove problematic, you can use these instructions to create a Vault and Ethereum playground. To install the plugin, configure mounts, enable authentication methods and manage policy, you need fairly powerful access in Vault.

However, you do not need to use the Vault root token. If you create an administrative user with the following permissions you can do everything in this exercise:. First, lets download and verify the authenticity of the plugin. We will be writing the plugin to the Vault plugins directory and registering it with the plugin catalog. The location of the plugin directory is configured in the vault.

Here is mine:. This setting is critical for the plugin to communicate with the Vault server during mount time. Then we register the plugin in the catalog. Lastly, we have to mount the plugin as a secrets backend. Now our plugin is installed and enabled. We configured the plugin as an administrative user. To properly demonstrate the power of Vault to manage access to the Ethereum backend, we will first create a non-administrative user who is not allowed to do any plugin management.

While we are still acting as an administrator, we will enable the Userpass Authentication Backend , configure it for MFA using Duo's free service , create a user named muchwow and, finally, attach this user to a policy that allows them access to the Ethereum backend. We also establish a fairly short TTL for this user— they will have to renew their session token before 10 minutes are up or they will have to re-authenticate. Care should always be taken when using passphrases.

One of the benefits of Vault is that it provides many forms of authentication which means that you can avoid the awkwardness of handling certain kinds of passphrases. Lastly, we configure MFA. I won't go over registration or device enrollment flows here.

Now, we stop being the Vault administrator, exhaling loudly as the weight of that responsibility leaves us, and we authenticate as a normal user. When we do this for the first time, we are asked to enroll a device:. Of course, even though we have MFA enabled on our account, we change our password for sanity's sake. What you see next to Address is your wallet address.

Your wallet and encrypted private key are stored in a file in the following locations based on operating system:. If you look inside that file, you will only see your encrypted key, never the unencrypted key, and some other metadata about the key. Geth does not support storing these private keys unencrypted. When you want to use that key to create a transaction using Geth, you will need to enter the passphrase you created so Geth can decrypt your private key in that file.
