Autonomous Smart Contracts
Introduction
Massa Blockchain introduces a groundbreaking feature known as Autonomous Smart Contracts. These smart contracts possess a unique capability: they can independently determine their own activation without any external actors. By the end of this section, you will gain a fundamental understanding of:
- The limitations of current smart contracts on existing blockchains
- How Massa Blockchain overcomes these limitations by empowering pre-programmed execution
- The inner workings and mechanisms behind autonomous smart contracts
- The use cases enables by autonomous smart contracts
Challenges with Existing Smart Contracts
In today's blockchain landscape, smart contracts face limitations when it comes to automating operations without external triggers. While automation lies at the heart of numerous industries, particularly in the realm of modern finance, only certain actions within decentralized finance (DeFi) protocols, such as lending and arbitration, are automated. However, even these actions are typically executed by off-chain bots. The absence of external calls prevents smart contracts, as they exist in current public blockchains, from performing automated operations.
Many decentralized protocols rely on recurrent triggers to ensure their smooth operation. For example, in decentralized lending protocols, borrowers lock crypto assets as collateral when obtaining loans. If the value of the collateralized asset drops below a specified threshold, the borrower's position becomes under-collateralized and requires immediate action. To maintain the integrity of the protocol, such positions must be liquidated. Currently, these liquidations are executed by organizations or individuals who run bots, often on centralized cloud services.
The Need for a Reliable Automation Mechanism
The reliance on recurrent triggers is a prevalent requirement across numerous applications. Consequently, significant time and effort have been invested in developing more dependable networks of bots to ensure the timely execution of transactions. However, since these solutions operate off-chain, there is no guarantee that the execution will be triggered effectively. In cases where bots fail to execute transactions, decentralized protocols face risks, as do the applications built on top of them.
