Hush has Sietch

Let's say you want to send a transaction to three friends, every Tuesday at 3:30pm, about your "secret meeting", and you use either ARRR or HUSH. Almost all transactions on ARRR have 2 outputs, the person receiving funds, and the "change output", which goes back to the original zaddr.

If you send messages to your 3 or 4, or any higher number of friends, especially with any kind of pattern (once per day, or every week, or every 39.4 hours), that can all be seen from public blockchain data. Shielded addresses on ARRR do not protect you.

With HUSH, we "round up" to protect the privacy of people communicating with between 1 and 8 others. So you can send a message to 4 people or 7 or just 1, and it looks exactly the same on the HUSH network. Talking To 3 Friends is not a problem when using HUSH.

If you want to routinely talk to 9 others or more, that is when it starts to stand out with HUSH, but you can just use another transaction, and send to 8 with one transaction and 1 with another.

Your ISPs know too much

HUSH was the very first cryptocoin to enforce encrypted Peer-To-Peer (P2P) connections, which is just like the little lock in your browser tab, which means "https" is being used. Modern websites are encrypted because so many problems and attacks happen when they aren't.

When Satoshi wrote Bitcoin, "http" was still widely being used and Bitcoin spoke in plaintext. Unfortunately just about every cryptocoin has kept this design flaw. HUSH requires encrypted connections between peers, where ARRR does not. This means that when you make a transaction, even though your address is not known, your "transaction ID" and IP address is known by ISP.

With HUSH, every node connection must be encrypted with https, which means your ISP (and the ISP of your ISP, etc..) does not know when you make a transaction, nor your "transaction ID". They always know your IP address, which is why not giving them your txid is so important. For the nerds: we use TLS 1.3 ONLY (no older TLS versions are allowed) and downgrade attacks are not allowed, i.e. if your node can't speak TLS 1.3 with valid ciphersuite, it cannot connect to the network.

ARRR exists for 2 years and more than 90% of the total supply has been mined already which means that a few individuals own most of the supply. Hush was created in November 2016 and only about 50% has been mined as of May 2021, over 4 years after the original launch of HUSH. HUSH has the same "emission schedule" as Bitcoin itself: block reward halving every 4 years.

Hush does not support KYC. Hush does not help the identity theft industry by linking personal information to blockchain data, which does not work to reduce fraud and is almost always stolen, re-sold and used for illegimate purposes:

Hush was the first coin ever to measure anonsets in real-time. Anonsets, AKA "anonymity sets" are a measure of how much privacy a privacy coin has. Hush was the first cryptocoin ever to measure this in real-time, via the getchaintxstats RPC, which Duke Leto worked on in Bitcoin Core.

Bitcoin Core has code from HUSH since Duke Leto upstreamed a change from Hush's version of getchaintxstats to the version in BTC Core. Pirate attempted to pay him to add this so-called zindex feature, but he refused, and so they are unable to measure their anonset in real-time.

Duke Leto wrote large portions of ARRR while being a Komodo Core developer for about two years and now it's unmaintained because there is nobody left that understands it. Additionally, KMD developers consider ARRR a separate project and make decisions that hurt the privacy of ARRR users.

Pirate disabled Duke's privacy features to KMD. Duke Leto wrote code to protect against a specific kind of attack called a linkability attack and since Pirate and KMD developers who actually maintain Pirate, who has no dedicated developers don't understand it, they commented it out.

Pirate has no developers. The original developers of Pirate were jl777 and Duke Leto, who gave jl777 the idea for Pirate, by asking "What could the opposite of -ac_public=1 mean"? The next day, the Pirate testcoin was born, but there no any other developers left in Piratecoin. The last commit on jl777 GitHub is a PR Duke Leto sent a long time ago from Hush.

Only SEO people left in Piratechain who pay CryptoForge from another privacy coin to write code for them, and he gladly takes code he wrote already and charges Pirates for it.

Nevertheless, CryptoForge still manages to steal Hush GPLv3 code (z_getbalances) and adding it to their MIT code. Pirate SEO people are even pay him to steal the code from Hush.

Pirate lacks Sietch

Pirate does not have the advanced privacy technology called "Sietch" which makes it much easier for blockchain analysis companies to attack.

Pirate requires a 1.6GB download of junk files. To run a full node you must download gigabytes of junk required for a disabled part of the code wasting the bandwidth of all users.

Pirate full node takes days to sync. Their full node is so slow to sync that they have built-ing the concept of downloading bootstraps (trusting somebody else's blockchain history!) into the full node itself. They truly don't grasp basic blockchain security principles.

Pirate is based on Sprout, a very old version of zaddrs that have been successfully attacked and are additionally extremely slow. Pirate based their chain on this old tech which is why it's so damn slow to sync a full node. HUSH was the very first coin to be based solely on Sapling zaddrs.
