Pirate Chain is a project about financial freedom. It provides 100% shielded z-z P2P transactions to preserve the privacy and anonymity of the user. It is run by a passionate community of volunteers.

Pirate OS is our series of operating systems that we are developing to enhance the security and privacy of those making transactions.

Think of it as an environment to run your wallet with the peace of mind of all the security features in place without the exploits and bugs the other operating systems have, plus its transportable since it is burned onto a USB. You simply power down your PC, plug in the usb, then boot from the usb itself and the operating system comes up. This has the distinct advantage of having the ability to transport your wallet anywhere with the USB, while being able to use it on almost any computer. The OS has MAC address spoofing, runs over TOR, and will eventually have the data encrypted as well as run over several VPNs. This ensures that your wallet is safe, secure and virtually untraceable when you make transactions.

Whilst Proof of Work is a great consensus mechanism to verify transactions, blockchains that only utilize PoW with small levels of hashing security can be attacked as the market value of those blockchains increases over time with what is known as a 51% attack (double-spending attack).

Delayed Proof of Work notarizes the transactions made on Pirate on to the Komodo blockchain, and then on to the Bitcoin blockchain. This was added to make Pirate more secure than any other Proof of Work chain out there by being resistant to 51% attacks. This is what makes it special compared to others.

Bitcoin is traceable. You can see exactly where everything goes, giving addresses linkability. If someone sends you bitcoin that came from a nefarious source, and the authorities know about it, you can be linked to that transaction. With Pirate, this cannot happen.

Pirate runs a couple Komodo Notary Nodes that donate funds to us every month, as well as having our main pools donate a portion of the pool fees to us.

We profit by having these funds used toward development, community bounties, etc. We also raise funds from the community to help pay for things like exchange listings and more.

With the sapling ceremony, there is really no issue with the trusted setup.

The short answer is, no.

The following link https://dexstats.info/richlist.php?asset=PIRATE only shows the unshielded mining rewards (which can still be shielded) and notarizations.

Remember, there are only two exceptions for transparent transactions, which are the block rewards from mining and notarizations. All the other transactions are shielded z2z.

The reason why this is true is that ZCash does not shield all of their P2P transactions, which ruins fungibility and their privacy. Zcash utilizes transparent addresses and those transactions make up 98% of their chain. This is not private. Aside from initial block rewards to pools, all of our transactions are private. Also, we have a bigger anon set and use dPoW.


Monero offers a private chain, but their privacy tech is inferior to ZCash. Fluffypony himself stated that zk-SNARKs offers better privacy than Monero. So a fully shielded chain like ours offers better privacy, a bigger anon set and we are 51% attack resistant with dPoW.

Newly mined coins (coinbase transactions) go to a transparent address for supply auditability reasons. So the short answer is, yes.


"Even if 1 septillion ARRR existed, "the answer is that a cryptographic hash is used to publish a commitment to each created note, and the zero-knowledge proof ensures that for each JoinSplit transfer, the total amount specified in these commitments..."(plus the transparent output) matches the total amount spent from the inputs.

The enforcement that the plaintext of notes is correct is done only when they are decrypted. In short, even if you make them in "secret" you cannot spend them because the numbers don't match and no one will accept the transaction."


"Pirate supply integrity is based on the coinbases mined and then reliance on sapling z -> z transactions not allowing to double spend or create new coins"

ARRRmada is an ecosystem of all the businesses and organisations that accept ARRR.


It is a directory of retailers and service providers that have ARRR as a form of payment.

Mining is the process of how blocks are created. Each new block locks in the last. In order to "undo" a block, you must be able to go backwards, remove that block, create a new one, and a new one to replace every block.


Since the more miners there are the higher the difficulty is to create a block, therefore miners secure the chain by making it harder to undo any part of it. It's a bit more technical than that, but that's the "simple answer".

zk-sNARKs (Zero Knowledge Succinct Non-Interactive Argument of Knowledge) refers to a proof construction where one can prove possession of certain information without revealing said information, and without any interaction between the two parties. Zero-knowledge proofs allow one party to prove to another that a statement is true without revealing any information beyond the validity of the statement itself.

A 51% attack refers to an individual or group controlling 50% or more of the network hashrate of a proof-of-work blockchain. The individual or group is then able to prevent new transactions from being confirmed on the blockchain, which allows them to halt payments between some or all users.


This would also allow them to reverse transactions that were completed while they were in control of the network, which means that they could double-spend coins.

Every privacy protocol uses different mathematical cryptographic strategies to obscure transactions and addresses. These obscured values are hidden in a pool called an "anonymity set."


The larger the group, the harder it is to identify your transaction/address (think "needle in a haystack", the larger the haystack, the harder it is to find the needle).


Pirate has the largest Anonymity Set of any cryptocurrency and it is perpetually growing. See the live report of Pirate's anonymity set size here https://anonset.dexstats.info/

Pirate believes in privacy by default, giving you the option to opt out of privacy.


You can proof your transaction by showing your viewkey. Although we do not recommend this.

wallet support questions

Due to extreme demand the lite wallet is syncing slow so at the moment we recommend using a full node wallet such as Pirate Ocean.

Our developers are working to improve the performance of the lite wallet.

Pirate provides several wallet options for different needs. The Treasure Chest wallet secures your funds by managing the Pirate blockchain on your computer.

The Lite wallet uses an offsite blockchain and is ideal for computers with lower resources.

A full node wallet occupies about 8GB of disk space.

First things first, you should always back up your private key. To find it, go to your receiving addresses, right click on your z-address (every single z-address has it's own private key) and click export private key.

This will bring up a screen where you can copy it and save it. It is highly recommended that you save it on a USB drive that you never plug in unless you need to retrieve your private key.

There is little to no compromise on anonymity. There is a small amount of metadata leakage to the insight server. The insight server will know the IP address associated with wallet transactions, based on the witnesses requested by the wallet.


However, using a VPN would protect the user against that leakage.

You can download the bootstrap file for the Pirate Chain wallets here:


Read this blog post for detailed instructions on how to install the bootstrap file:


Read this blog post for detailed instructions on how to install the zcash parameters file:


Whilst this is best practice with other coins due to the anonymity features of ARRR you do not have to do this. 


Of course exceptions apply, especially in the case when you have used an address to send funds to an exchange or posted it anywhere online. In these cases we do recommend generating a new address.


Please note, that by having too many addresses in a wallet holding ARRR, you are likely to negatively impact the performance of that wallet.

To improve the speed of your wallet blockchain synchronisation you can download the bootstrap file.


For links and information on how to install it read https://pirate.black/bootstrap-zcash-parameters-installation-guide/

Yes, if you prefer running your wallet with the command line, the updated instructions can be found here: Run Pirate using CLI

Watch the how-to video here: https://pirate.black/how-to-videos/


You do so by sending a DM to the "@ARRR TipBot" in Discord.

Then type the command !arrrtip withdraw yourtreasurechestaddress amount

If unsure use also !arrrtip help for a full list of commands.

The default transaction fee for the  Treasure Chest wallet is 0.0001 ARRR.

Exchanges have their own fee structure, which is out of the control of the Pirate Chain team.

Buy XMR from https://localmonero.co/ or open an account to buy Bitcoin from CoinEx or Bitcoin.com.

You can exchange XMR for Bitcoin and then ARRR in a number of exchanges. Visit https://pirate.black/exchanges/ for more information.


Most exchanges we have will offer a conversion between Bitcoin (BTC) and ARRR as a main trading pair.


You can find a list of the exchanges we are listed on here.

We always recommend doing your own research before using any exchange. We cannot endorse any.


We also recommend using a DEX when possible.


Visit the exchanges page for more information.

A centralized exchange is a platform where you can buy or sell digital assets, but you have to trust a third party to monitor the transaction and secure the assets on behalf of the buyer and the seller. Their deals aren’t tracked on the blockchain, and they hold all of the user's assets on the exchange.


A Decentralized Exchange differs from a Centralized Exchange in that it doesn’t have a third party on which you have to rely on. All of the funds in this exchange remain stored on the blockchain.

Your deposit might take time to register in an exchange. How much time depends on the exchange you are using and the state of that exchange's wallet.

The development team works closely with exchanges to ensure that they maintain their wallets adequately to minimize disruption.

You can find such list here: https://pirate.black/exchanges/

Different exchanges list different prices for a variety of reasons. Mainly liquidity, daily volume, size of order book and a few others.

The Pirate Chain team has no control over external companies such as exchanges.

Before you rush to the exchange that displays the lowest price, please do some research first. That exchange might be experiencing some kind of problem.

frequently asked questions about mining pirate arrr

After a halving, the reward for mining a block is half than the previous (128 becomes 64, 64 becomes 32, etc)

This number was chosen by the initial creators of Pirate Chain (ARRR).

For more information on how to mine Pirate Chain (ARRR) visit the mining page.

Mining is an area where things change fast and profitability can vary drastically. This is why we always recommend doing thorough research before considering electricity costs and which hardware to use.

Some more information about hardware can be found in our mining page.

There is no straightforward answer. The best we can say is that the price depends on multiple factors so the halving sometimes can affect the price and sometimes it does not.

This video has some information about mining ARRR.


You can mine ARRR both by using CPU or GPU, however this might not be profitable.

ASIC mining is dominant.
