A shared notebook
A blockchain is a public record kept by many computers at once. Anyone can read it. Nobody can quietly change or erase what is already written, because every computer keeps its own copy and checks the others.
To add something, you sign it with a secret key that only you hold. The signature proves the entry came from you, the same way a handwritten signature would, but it can’t be forged.
Your wallet
A wallet is the thing that holds your secret key. It has a public address (like 0x71B2…) that identifies you, and a private key that signs for you. Your wallet is your myblogs identity: whoever holds the key controls the profile.
You can use a wallet you already have (a browser extension), or let myblogs create one for you when you sign up with email. Either way, the private key stays with you. It is never sent to a myblogs server. Email wallets can be unlocked with a passkey (fingerprint, face or device PIN) or remembered on your own device, so you only need your recovery phrase in an emergency.
What myblogs keeps on the blockchain
Only a small index, kept by a program called the registry:
- which wallet owns which username,
- a fingerprint of each profile and story (its content ID),
- who published each story, and when it was changed or removed.
The stories, pictures and profiles themselves are not on the blockchain. They live on IPFS (see How the platform works). The blockchain only remembers their fingerprints, so anyone can check that what they read is exactly what the writer published.
Which blockchain?
myblogs currently uses Base Sepolia, a public test network of Base. It works like the real thing, but its coins have no money value, which makes it right for this stage of the project. A move to Base’s main network may come later.
Why bother?
Because no single company has to be trusted with the list of who wrote what. Any website that reads the same registry shows the same community, so your writing isn’t locked into one website.
