Try Tau in four steps.
On Tau the rules change by agreement, and every account can carry a rule of its own that the chain itself checks. Try it on Tau Testnet Alpha: a few minutes in this browser, nothing to install. Test AGRS have no value.
A key made in this browser and never sent anywhere. Your first transaction brings 100,000 test AGRS from the testnet’s faucet.
For example: no payment above 1,000 test AGRS. From then on every node checks your payments against it, not an app.
A block takes your rule in. From then on it is part of the chain’s state, and the Explorer shows it like any other transaction.
One creature the whole testnet feeds. Each meal is a payment, and every evening the wallets that fed it vote on how it changes.
Every step is a real transaction on Tau Testnet Alpha, signed in your browser. This page only reads what your wallet did and what the chain says.
