+Returns the estimated production time of a block. Validators report their UTC

+#### Results:
+
+* `null` - block has not yet been produced
+* `i64` - estimated production time, as Unix timestamp (seconds since the Unix epoch)

+# Paper Wallet
+
+This document describes how to create and use a paper wallet with the Solana CLI
+tools.
+
+{% hint style="info" %}
+We do not intend to advise on how to *securely* create or manage paper wallets.
+Please research the security concerns carefully.
+{% endhint %}
+
+## Overview
+
+Solana provides a key generation tool to derive keys from BIP39 compliant seed
+phrases. Solana CLI commands for running a validator and staking tokens all
+support keypair input via seed phrases.
+
+To learn more about the BIP39 standard, visit the Bitcoin BIPs Github repository
+[here](https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki).

+# Installation Guide
+Follow this guide to setup Solana's key generation tool called `solana-keygen`
+
+{% hint style="warn" %}
+After installation, ensure your version is `0.21.2` or higher by running `solana-keygen -V`
+{% endhint %}
+
+## Download
+First, download the latest release tarball from GitHub.
+
+1. Setup download url
+
+  ```bash
+  solana_downloads=https://github.com/solana-labs/solana/releases/latest/download
+  ```
+
+2. Specify the download file based on your machine
+
+  **MacOS**
+  ```bash
+  solana_release=solana-release-x86_64-apple-darwin.tar.bz2
+  ```
+
+  **Linux**
+  ```bash
+  solana_release=solana-release-x86_64-unknown-linux-gnu.tar.bz2
+  ```
+
+3. Download
+
+  ```bash
+  curl -L -sSf -o solana-release.tar.bz2 $solana_downloads/$solana_release
+  ```
+
+## Extract
+Next, extract the tarball
+```bash
+tar xf solana-release.tar.bz2
+```
+
+## Add to "PATH"
+Now add the tool to your PATH environment variable with the following command
+```bash
+export PATH="$(pwd)/solana-release/bin:${PATH}"
+```
+
+## Check
+Finally, check that `solana-keygen` can be run by running
+```bash
+solana-keygen -V
+```

+# Creating a Paper Wallet
+
+Using the `solana-keygen` tool, it is possible to generate new seed phrases as
+well as derive a keypair from an existing seed phrase and (optional) passphrase.
+The seed phrase and passphrase can be used together as a paper wallet. As long
+as you keep your seed phrase and passphrase stored safely, you can use them to
+access your account.
+
+{% hint style="info" %}
+For more information about how seed phrases work, review this
+[Bitcoin Wiki page](https://en.bitcoin.it/wiki/Seed_phrase).
+{% endhint %}
+
+## Seed Phrase Generation
+
+Generating a new keypair can be done using the `solana-keygen new` command. The
+command will generate a random seed phrase, ask you to enter an optional
+passphrase, and then will display the derived public key and the generated seed
+phrase for your paper wallet.
+
+```bash
+solana-keygen new --no-outfile
+```
+
+{% hint style="warning" %}
+If the `--no-outfile` flag is **omitted**, the default behavior is to write the
+keypair to `~/.config/solana/id.json`
+{% endhint %}
+
+{% hint style="info" %}
+For added security, increase the seed phrase word count using the `--word-count`
+argument
+{% endhint %}
+
+For full usage details run:
+
+```bash
+solana-keygen new --help
+```
+
+## Public Key Derivation
+
+Public keys can be derived from a seed phrase and a passphrase if you choose to
+use one. This is useful for using using an offline-generated seed phrase to
+derive a valid public key. The `solana-keygen pubkey` command will walk you
+through entering your seed phrase and a passphrase if you chose to use one.
+
+```bash
+solana-keygen pubkey ASK
+```
+
+{% hint style="info" %}
+Note that you could potentially use different passphrases for the same seed
+phrase. Each unique passphrase will yield a different keypair.
+{% endhint %}
+
+The `solana-keygen` tool assumes the use of the BIP39 standard English word
+list. If you chose to deviate from the word list or used a different language
+for your seed phrase, you can still derive a valid public key but will need to
+explicitly skip seed phrase validation.
+
+```bash
+solana-keygen pubkey ASK --skip-seed-phrase-validation
+```
+
+For full usage details run:
+
+```bash
+solana-keygen pubkey --help
+```

+# Paper Wallet Usage
+
+Solana commands can be run without ever saving a keypair to disk on a machine.
+If avoiding writing a private key to disk is a security concern of yours, you've
+come to the right place.
+
+{% hint style="warning" %}
+Even using this secure input method, it's still possible that a private key gets
+written to disk by unencrypted memory swaps. It is the user's responsibility to
+protect against this scenario.
+{% endhint %}
+
+## Running a Validator
+
+In order to run a validator, you will need to specify an "identity keypair"
+which will be used to fund all of the vote transactions signed by your validator.
+Rather than specifying a path with `--identity-keypair <PATH>` you can use the
+`--ask-seed-phrase` option.
+
+```bash
+solana-validator --ask-seed-phrase identity-keypair --ledger ...
+
+[identity-keypair] seed phrase: 🔒
+[identity-keypair] If this seed phrase has an associated passphrase, enter it now. Otherwise, press ENTER to continue:
+```
+
+The `--ask-seed-phrase` option accepts multiple keypairs. If you wish to use this
+input method for your voting keypair as well you can do the following:
+
+```bash
+solana-validator --ask-seed-phrase identity-keypair voting-keypair --ledger ...
+
+[identity-keypair] seed phrase: 🔒
+[identity-keypair] If this seed phrase has an associated passphrase, enter it now. Otherwise, press ENTER to continue:
+[voting-keypair] seed phrase: 🔒
+[voting-keypair] If this seed phrase has an associated passphrase, enter it now. Otherwise, press ENTER to continue:
+```
+
+Refer to the following page for a comprehensive guide on running a validator:
+{% page-ref page="../running-validator/README.md" %}
+
+## Delegating Stake
+
+Solana CLI tooling supports secure keypair input for stake delegation. To do so,
+first create a stake account with some SOL. Use the special `ASK` keyword to
+trigger a seed phrase input prompt for the stake account and use
+`--ask-seed-phrase keypair` to securely input the funding keypair.
+
+```bash
+solana create-stake-account ASK 1 SOL --ask-seed-phrase keypair
+
+[stake_account] seed phrase: 🔒
+[stake_account] If this seed phrase has an associated passphrase, enter it now. Otherwise, press ENTER to continue:
+[keypair] seed phrase: 🔒
+[keypair] If this seed phrase has an associated passphrase, enter it now. Otherwise, press ENTER to continue:
+```
+
+Then, to delegate that stake to a validator, use `--ask-seed-phrase keypair` to
+securely input the funding keypair.
+
+```bash
+solana delegate-stake --ask-seed-phrase keypair <STAKE_ACCOUNT_PUBKEY> <VOTE_ACCOUNT_PUBKEY>
+
+[keypair] seed phrase: 🔒
+[keypair] If this seed phrase has an associated passphrase, enter it now. Otherwise, press ENTER to continue:
+```
+
