How Do Smart Contracts Work?
A smart contract is an agreement among two or more parties that contains terms and rules that all agree upon.
Decentralization
Smart contracts run on a distributed blockchain network, meaning they're spread among multiple nodes within it. Decentralized execution makes smart contracts more secure by eliminating one entity from controlling how they're executed - thus, less vulnerable to manipulation or censorship.
Transparency and Trust
Smart contracts provide transparency and trust, as anyone can view the code that runs them on the Blockchain. Cryptographic principles help establish trust among parties involved in such agreements, making it hard for anyone to dispute its performance.
No Middlemen
Smart contracts are self-executing and automated, meaning they do not rely on intermediaries for execution and administration, eliminating costs as well as potential points of failure. This helps lower costs while simultaneously eliminating possible failure points.
Blockchain Technology
Blockchain technology uses smart contracts. Smart contracts are automated agreements that run on blockchain networks that autonomously execute without needing middlemen - making decentralized contract execution possible.
Decentralized
Blockchains are decentralized, immutable, and unchangeable technologies that facilitate smart contracts to help strengthen trust between parties. Their transparency ensures contract details can be seen and verified by all relevant parties.
Unchangeability and Security
Once deployed on the blockchain, smart contract code becomes secure and hardened against tampering. Blockchain immutability ensures that contracts cannot be changed - providing a safe foundation for transactions.
Supply Chain Management/Bottleneck-Tracking
Smart contracts automate and verify various stages of the supply chain, from procurement through delivery, from procurement through payment release. Payment release can occur automatically when certain conditions, such as delivery verification, have been fulfilled, providing more control for logistics processes and payment release for payment releases.
