A blockchain is not made for human beings. It is a giant data string, full of hashes and code and more hashes. It is made as a database which can be read and validated by machine. But it is not made for a database to be accessed by humans.
Which is considerably sad. Because a blockchain is the most useful database ever invented. It is hyper accessable. Content is just there. Everywhere, for everyone, and to every time. Data can’t have a better accessability than data on a blockchain.
Now, unfortunately, blockchain data is not made for humans. Just look at how you access it: All popular data explorers, like bico.media, whatsonchain.com or others, access onchain content by a transaction id. You know what this is? It is a very ugly and very long hexadecimal string. Zero chance to ever memorize it.
All this unconditional and universal accessability is wasted, if you need something outside your brain to use it. Real accessability means that you can access data everywhere, everytime AND without the help of any tool outside your brain. Hyper Accessability means that you, as a human being, have everything needed to get access.
MetaHandle solves this. A MetaHandle is a data point on the blockchain, which links a transaction id to any word. A MetaHandles serves like a human entry point to onchain data. It is like a door to onchain. You find the door and open it with a keyword, which can be any word you like.
Other then external databases, MetaHandles organize the blockchain itself. They are on the chain itself; the tunnel from a human memorizable word to a transaction id will remain forever.
