Blockchain-based application platforms, like Ethereum, are designed to host decentralised applications and digital assets.
In traditional computing environments, applications often rely on centralised servers and intermediaries to operate. In contrast, blockchain-based platforms are traditionally built upon distributed networks, meaning they are operated by a widespread group of independent and non-coordinated parties that are each responsible for upholding the system’s rules. This makes the platform more robust by being less reliant on a single or small group of individuals or businesses.
One of the defining features of blockchain app platforms is their use of smart contracts—self-executing programs that automatically enforce the terms of an agreement. These contracts enable fully automated interactions, removing the need for intermediaries and providing a transparent way for users to transact or engage with applications. This means that all interactions, whether simple transfers or complex app engagements, are executed based on predefined rules that are openly visible on the blockchain.
Additionally, every transaction is secured by cryptographic tools. The ability of transaction data to be tamper-proof and for participants to independently arrive on the same transaction history without needing a centralised authority depends on cryptography. The transparency of how this math is implemented within the system, coupled with open-source development, is core to what makes these blockchain-based systems trustworthy (or not).
Overall, blockchain-based application platforms often aim to offer a flexible foundation for building a wide range of services and digital assets, with advantages in automation, transparency, and security compared to traditional platforms.
