Description

The contract implements a simple decentralized posting system in which content publication is permissionless, while voting requires ownership of a designated ERC-20 token called Hash DB Token (Karma) 0x0bF43e7408959fe8030d3729760f179403A20147. When a user upvotes a post, a token is transferred directly from the voter to the publisher, linking voting activity to an on-chain economic transfer.
