Why this website?You're right, most of the content lands on our official self-hosted Gitea website first, but it is nice to have a minimalistic and non-bloated js-free website to read some content as well.
What is Hush?Hush is Free Software (like Open Source, but better), which allows you to Speak And Transact Freely. That is the core mission of the software and global community of cypherpunks that make the Hush software and peer-to-peer network possible. Hush is not a company nor foundation. We are not based in any country. We are a decentralized cypherpunk community and continue to research the bleeding edge in privacy. 1 HUSH = 10000 encrypted messages which have censorship resistance backed up by Bitcoin hashrate security, which is why Hush is a Store-of-Privacy.
Where can I get Hush?The only official place to get Hush source code and binaries is git.hush.is, which is the Hush Gitea instance, which replaces Github since Github has suspened the account of Duke Leto for unknown reasons. Duke develops code free from the censorship and racism of Github/Microsoft.
What is Hush Privacy Policy?Our policy is to store as little metadata as possible, or not at all. Hush team members will never ask for your personal information, if someone is asking for your legal name, physical address, phone number, email/etc that is a scammer! We only ask for as little possible information to debug support requests, such as Operating System versions, wallet versions and other technical information. Hush does not mine your personal privacy to sell to advertisers, you keep your privacy and your dignity. Privacy is a precious asset and Hush allows you to store it in digital form.

This website is purely for marketing and education purposes and our peer-to-peer network does not rely on it in any way, not does our P2P network rely on DNS, which we believe is completely untrustable, just as Bitcoin developers rightly believe.

When using some Hush software, there are mandatory or optional features that require talking to third party websites and APIs. We cannot control how they use metadata, such as IP address, MAC address and browser details such as your language, timezone, screen resolution and other details.

Hush uses are cloudflare.com/netlify.com for Denial-of-Service protection and SSL (only for websites, not p2p network), coingecko.com for price feeds, the price feeds are optional and can be turned off in settings. Hush is designed to preserve our user privacy in every way, so when Hush software requests data from Coingecko.com, it always requests all possible data, and then only uses the data it needs, versus asking coingecko.com for only the data it needs, which leaks the metadata of what this particular wallet is interested in. This Private Information Retreival (PIR) technique is just one of many ways Hush implements Extreme Privacy at every level of the software stack.

If you do not want your IP address, MAC address and browser metadata we highly recommend using Tor or i2p and/or the TAILS, Whonix or Qubes operating systems with Hush.

How to recover HUSH from the old webwallet?Don't use webwallets! SDL can import old-style HUSH v2 private keys, which start with K or L. If you have a very old HUSH private key, from hushd or a web wallet, you can now import these funds to SDL! SDL will automatically "sweep" funds out of this private key, into a zaddr that is part of your Seed Phrase, it may take time for your funds to be confirmed in a new block and show up in your wallet.

How can I buy/get Hush anonymously?The best way is to mine Hush with ASICs.

The less private way is to buy Bitcoin on localbitcoins or Bisq and exchange them with safe.trade

Consider some localbitcoins alternatives that provide an ability to buy BTC/XMR and other cryptocoins with cash in person, such as paxful, localcoinswap, hodlhodl and others
Where can I spend Hush?safe.trade - Centralized Exchange

Can I mine HUSH on a personal PC?No, only ASIC mining is recommended. HUSH uses the same Equihash (200,9) algo as Zcash, Horizen or Komodo, all miners are able to switch to HUSH mining at any second.
What is the best ASIC miner to use for mining HUSH?Z15, Z11, A9++, A9+, A9, but only the first two can be considered as profitable, also please note that it varies drastically, do your own research, asicminervalue.com may help.
What are the mining specifications?Block Time: 75 seconds, block reward: 3.125 Hush and 10% goes to Founders Reward, so 2.8125 Hush, difficulty adjustment: every block, Digishield V3. HUSH total supply is 21 million and reward halving happens every 4 years, the same as Bitcoin. P2P and RPC port is 18030 and 18031 accordingly.
What mining pool do you recommend?LuckPool and CoolMine are the mining pools we currently recommend as they follow all needed privacy precautions to keep your zaddr address private.
Can I install Hush on my phone?Yes, please "de-google" your device with LineageOS first, then you can grab the .apk file from git.hush.is/hush/SilentDragonAndroid/releases and install SilentDragon for android
Why is my balance different than the explorer?This can happen for a few reasons. Your node may be out of sync, and still finding new blocks which contain payments to your address. You may not have imported all the private keys you thought you did. Use the validation function to check if an address is in your current wallet.

If your wallet is rescanning, it will show the balance as of the block height it is processing. You will see the balance "jump" higher when it finds a new transaction which pays one of your addresses. Your full balance will be shown when you have processed the latest block and regain "syncedness".
What does a Hush address look like?It is not possible to send funds to transparent addresses (public such as Bitcoin addresses), but shielded only that starts with zs1 which is the prefix for Sapling Shielded Addresses. If your address starts with zc instead of zs1, it is a Sprout address and it's not valid on the current HUSH mainnet.

For the above reasons, KMD, VRSC and SAFE addresses are all compatible, with the exact same public key generating the same exact address on KMD, VRSC, SAFE and HUSH and all the side chains (smart chains) of these respective platforms. If you own a taddr or zaddr on any one of these blockchains, you own the exact same address on all the blockchains.
How can I run a SilentDragonLite backend?You will need a VPS with at least 2 vCPUs and 4GB of RAM to compile software: https://git.hush.is/jahway603/hush-docs/src/branch/master/hush-lite-server.md
