A blockchain advertising platform is a decentralized digital advertising system that uses blockchain technology to increase transparency, trust, and efficiency in the ad ecosystem. Unlike traditional platforms, it records all transactions and interactions—such as impressions, clicks, and payments—on a public, tamper-proof ledger. This eliminates fraud, reduces reliance on intermediaries, and ensures advertisers only pay for verified engagement. Publishers are paid fairly and promptly, often using cryptocurrencies or tokens. These platforms are ideal for Web3 projects, crypto brands, and decentralized apps, offering secure, data-private, and censorship-resistant advertising solutions.
