A chain forked from Ethereum’s client, tied to the exchange that launched it. The repository most data sites link to is the exchange API, not the chain.
The busiest codebase of the ten. The repository data sites point to has been archived since January 2025, so its link shows a project frozen for over a year.
A network of nodes that reports outside data on-chain rather than a chain of its own. Its LINK token carries no vote at all, only payment and a staking deposit that can be slashed.
A chain where hiding the amounts is part of the protocol. The repository every directory links to is archived: its node software was switched off in July 2026, and the chain kept going without it.
Its earliest blocks paid a reward drawn at random from the previous block’s hash, anywhere from 1 to 999,999 DOGE. Every block since has paid a flat 10,000 DOGE, forever, with no cap ever written into the code.
GitHub labels its code GPL-3.0. No such file exists anywhere in the repository: its own Cargo.toml, and every licence file actually shipped, say MIT or Apache-2.0 instead.
Its official website repository has taken zero commits in 90 days. The software that actually runs the network lives elsewhere, took 156, and nobody company controls either one.
A direct fork of Bitcoin’s own code, four times faster and capped near 84 million, not exactly on it. Its privacy layer suffered a real exploit in April 2026, patched the next day.
Hides the sender, the receiver and the amount of every transaction by default, with no option to turn that off. Its block reward never reaches zero, and the privacy upgrade several 2026 pages describe as live has not shipped.
Burns every lumen collected in fees into a locked account nobody can ever reach, paying no miner and no validator. A bug let it create lumens for real in 2017, before a validator vote ended its own inflation rule in 2019.
The repository most data sites link to, input-output-hk/cardano-sl, has been archived since July 2020 and still carries more stars than the client that replaced it. That successor’s proposal repository has merged 771 pull requests since 2020, feeding an on-chain vote most chains don’t have.
Its fee switch, turned on in December 2025, routes a share of swap fees to buy back and burn UNI. On-chain supply still reads exactly 1,000,000,000: burning moves tokens to a dead address, it never decrements that counter.
What gets a profile here
A project earns a profile when enough of what it says about itself can be checked at a primary source: its own repository, its own contracts, a node we can query. Everything we could not establish stays on the page, in a table, with the reason. A profile is not a recommendation. The rating it carries measures what can be checked about the protocol, never what the token will be worth.
Each claim carries the address it came from and the date it was read, so anyone can land where we landed. Where an aggregator is our only source, the row says so rather than borrowing its confidence.
There are few profiles because each one takes a day. We would rather publish one page that holds up than fifty that repeat each other.
