What are smart contracts?

Smart contracts are essentially software or protocols that can, in many cases, replace a paper contract. Instead of a paper document, they record the terms of the contract in digital form and ensure that these conditions are met.

History of smart contracts

American computer expert Nick Szabo introduced the concept of smart contracts back in 1994. The same Szabo who is sometimes linked with the anonymous inventor, or inventors, of Bitcoin, Satoshi Nakamoto. In Szabo's original concept, the potential applications of these contracts were brilliantly described, for instance in the derivatives sector.

Operating principle

Imagine a beverage vending machine. By inserting a coin, you either get a drink or your money back. A simple program in the machine dictates everything. Similarly, a smart contract ensures that if certain conditions are met, a specific action takes place – like making a payment.

+Advantages of smart contracts

They operate on blockchain technology. Beyond security, smart contracts also offer efficiency and speed. Their automation can save both time and costs. Moreover, they are increasingly standardized, making their selection and use easier.

-Disadvantages of smart contracts

However, not everything is rosy. Code errors can have catastrophic consequences, as shown by the 2016 DAO case where hackers stole $60 million. Legal uncertainties and implementation costs can also deter their broader adoption.

Cryptocurrencies and smart contracts

Although Bitcoin was not originally designed as a platform for smart contracts, its technology inspired the creation of many other platforms, such as Ethereum or Stellar Lumens, which fully support smart contracts.

Smart contracts in the czech legal system

Even though the Czech Civil Code allows freedom of choice regarding the type of contract, there are still many legal questions surrounding smart contracts. For legal recognition, a smart contract must meet certain criteria, and it's essential to understand that smart contracts, if they meet these criteria, can be legislated and recognized as valid contracts in the Czech Republic.


Smart contracts offer numerous opportunities in the digital age. Despite their advantages and disadvantages, their potential and growing influence in the realm of digital transactions and contracts cannot be denied. As always, technology and law must grow and evolve together to adapt to new challenges.
