A peek at the privacy project Iron Fish from the background

Iron Fish is an easy-to-operate privacy protection trading platform based on Web3 technology.


Selling point:

Its purpose is mainly to solve the pain points of slow cryptocurrency transactions, no privacy due to transaction broadcasting of all details, and imperfect and difficult-to-operate other privacy protection tools on the market.

Iron Fish does this by creating a new cryptocurrency called Iron. Users can operate nodes, mine, and trade. The specific information can only be viewed after the owner discloses the view key

Iron Fish has launched the test network (reference:

Provide incentives for contributing behavior. Different points can be obtained for different actions. After the mainnet is launched, IRON tokens can be shared in equal proportions with these points (note that the currently tradable iron in the market is a stable currency, which is easy to confuse). Those who get the highest points for each item can get an additional Iron Fish NFT. At present, the test network is relatively active, with users operating every minute. Official Twitter calls its testnet one of the largest in the world.

3. Company background

The company was founded during the COVID-19 epidemic in 2020, based on the frequent electronic transactions and the lack of privacy protection. IronFish got its name from World War II. In the Indian encrypted information system used by the US military, Ironfish means submarine. The founder believes that Ironfish can protect the network security in the cyber world just like a submarine protects the people in war, which is quite tender.

The website design style is clear and concise but not shabby. Blue, pink, and white are the main colors. The pattern has the feeling of Robinhood, and the logo is more memorable.


The company’s social media (brand twitter, CEO’s personal twitter) and website are all close to the people and highly interactive.

The official website will list the development stage and expected completion time on the google sheet, and carefully explain the meaning of each stage. Every small detail implements the meaning of “accessibility”, and is not afraid to let followers clearly understand the trend

In addition, there are detailed instructions on how to download IronFish on the testnet and conduct currency transfer tests (the level of detail is similar to the github installation tutorial, and even the homebrew installation method is covered), and each block is clearly listed here: https: //
