About PriFi.info

How entries are checked

Primary sources come first: laws, official gazettes, regulators and courts for the country rules; each exchange's own market data and notices for the listings; and each project's documentation, code, audit reports and governance records for the protocol profiles. For the rules and listings, press reports are used only where no primary source could be reached, and an entry that rests on them alone is marked Reported.

Every country rule, exchange listing and profile, and every entry on the Timeline, Funding, Watchlist, Wallets and Calendar pages and in the Bitcoin privacy section, has a confidence level, Confirmed, Reported or Not verified, and the day it was checked. The tracked protocols and the coin basket are reviewed as a whole, and the types and statuses of the tracked protocols are PriFi.info's own classification.

Sending a correction

Send the address of the page, what is wrong and a link to a document that shows it, a primary source where possible, using the contact details under Contact. A correction without a source can still point to a problem, but it cannot be applied until one is found.

How a correction is applied

Each correction is checked against its source. If the source bears it out, the entry is corrected, its checked-on date moves to the day of the re-check, and a note on the Changes page and in its RSS feed says what changed. A new status, rule level or exchange listing is also logged there automatically at the next hourly update, with the value it replaced. Mistakes the site finds itself are corrected the same way.

The server

The site runs on one always-on server, which collects the data, builds the pages and serves them. It fetches market caps, prices and the Zcash pools every five minutes and TVL every hour, rebuilds the pages every hour, and refreshes the full daily histories once a day, after 01:20 UTC.

The server also follows six chains for the live ticker on the Activity page: the Tornado Cash, Railgun and Privacy Pools contracts on Ethereum through PublicNode, Monero through the public nodes run by Cake Wallet and Seth for Privacy, Zcash through ZecBlock, the Privacy Cash program on Solana through Solana's public RPC, Liquid through Blockstream's Esplora API and Aztec through Aztecscan. It keeps what they send for 7 days, then deletes it, and the ticker shows only what any public node sees.

The pages and the code

Pages are plain HTML, built on the server. The only scripts are the site's own, which draw the charts and the map, filter and sort the lists, count down to the dates ahead and keep the figures up to date. The charts use uPlot, under the MIT licence; the rest of the code was written for the site. The code is not public yet, and may be released publicly later.
