The Origins of Smart Contracts and Their Development

Exploring the Beginning and Key Moments in Smart Contracts' Evolution

Decades ago, when dial-up was the norm, a concept was born that would underpin a trillion-dollar crypto industry.

Picture a world where agreements, big or small, are as seamless as a click, where breaches are not a concern because the contract itself ensures fidelity.

For Instance, Jane, a digital artist, sketches her latest masterpiece. Within moments of completion, a buyer from halfway around the world purchases it for $10,000.

There's no middleman, no lengthy discussions, and no tedious paperwork. Just a simple digital handshake. This magic? It's the power of smart contracts.

The Origin of Smart Contracts

The concept of smart contracts was first proposed in the early 1990s by Nick Szabo, an American computer scientist. Szabo defined smart contracts as "a set of promises, specified in digital form, including protocols within which the parties perform on these promises".

He envisioned smart contracts as a way to automate the execution of contracts, thereby reducing the need for third-party intermediaries and making contracts more efficient and secure.

Szabo's work on smart contracts was inspired by the concept of "Ricardian contracts", which were proposed by British philosopher David Ricardo in the early 19th century. Ricardian contracts are contracts that are written in plain language so that they can be easily understood by both parties.

Szabo believed that smart contracts could be implemented using a blockchain, a distributed ledger technology that allows for secure and tamper-proof transactions.

In 1994, Nick Szabo introduced the concept of smart contracts in his article, "Smart Contracts: Primitives for Decentralized Protocols", exploring their potential applications.

In 1996, in "The Design of Smart Contracts", Szabo expanded on his previous work, delving into the technical challenges of smart contract implementation.

From 1998 to 2005, Szabo proposed a blockchain system to maintain land ownership records. This idea was ahead of its time, given the absence of an effective replicated database system he was not able to implement it.

Nonetheless, blockchain developments have now facilitated the realization of Szabo's proposals. Like a domino effect. One idea propels another, producing a ripple effect of advancements we hadn't previously fathomed. Without one, the other wouldn't exist, pushing us to continually evolve.

Szabo's writings on smart contracts have been foundational for blockchain's growth. He envisioned a digital marketplace facilitating trustless transactions without intermediaries. These cryptographic processes became known as "smart contracts".

Although Szabo didn't personally realize smart contracts on leading blockchains, others like Ethereum did. Developers continually enhance layer 1 blockchains like Solana and Aptos and innovate with improved programming languages for smart contract implementation.

The First Blockchain-Based Smart Contract

The first blockchain-based smart contract was created in 2009 with the release of the Bitcoin protocol. Bitcoin is a cryptocurrency that uses a blockchain to track transactions. The Bitcoin protocol includes a set of rules that define how smart contracts can be created and executed.

For example, the Bitcoin protocol includes a function called OP_RETURN that allows users to store data on the blockchain. This data can be used to store the terms of a smart contract.

The Development of Ethereum

The development of Ethereum in 2015 further popularized the concept of smart contracts. Ethereum is a blockchain platform that is specifically designed for smart contracts. Ethereum's programming language, Solidity, makes it easy to create complex smart contracts.

Solidity is a Turing-complete language, which means that it can be used to create any type of computation. This makes it possible to create smart contracts that can do anything from trading cryptocurrencies to managing supply chains.

Ethereum was a groundbreaking innovation when it was first released. It was the first major blockchain to implement smart contracts, which are self-executing contracts that can be used to automate a wide variety of financial and non-financial transactions.

Ethereum quickly became the most popular blockchain for developing decentralized applications (dApps), which are applications that run on the blockchain and are not controlled by any central authority.

The network effect helped Ethereum to establish itself as the top Layer 1 blockchain player in the crypto market.

Further Advancements

Ethereum was a groundbreaking innovation when it was first released, but it also had some shortcomings. One of the biggest problems was its scalability. The Ethereum network can only process a limited number of transactions per second, which can lead to congestion and high transaction fees.

In response to these shortcomings, several Layer 1 blockchain projects have been developed. Even developers who originally were with Ethereum ventured into their own projects such as Polkadot and Cardano.

These projects are designed to be more scalable, secure, and energy-efficient than Ethereum. Some of the most up-and-coming Layer 1 blockchains include Solana and Aptos as mentioned before.

Solana is a high-performance blockchain that can process up to 60,000 transactions per second. It is also very energy-efficient, using a fraction of the energy that Ethereum does. Solana uses a unique consensus mechanism called Proof of History (PoH), which allows it to achieve such high throughput.

Aptos is a new blockchain project that is being developed by the team behind Diem. Aptos is designed to be more secure and scalable than Ethereum, and it uses a new programming language called Move. Move is a high-level language that is designed to be secure and efficient for smart contracts.

Both Solana and Aptos are promising new blockchain projects that could challenge Ethereum's dominance. Solana offers high throughput and energy efficiency, while Aptos offers security and scalability. It will be interesting to see how these projects develop in the future.

Use Cases of Smart Contracts

Thus, the applications for smart contracts seem limitless, with the potential to reshape the following industries:

  • Finance: smart contracts are being used to create decentralized exchanges (DEXs), which allow users to trade cryptocurrencies without the need for a centralized exchange.

  • Art: smart contracts are being used to create digital art that is tamper-proof and can be easily traded. This could make it easier for artists to sell their work (aka NFT).

  • Decentralized storage: smart contracts are being used to create decentralized storage networks that allow users to store data in a secure and tamper-proof way without the need for a centralized storage provider.

  • Voting: Smart contracts are being used to create decentralized voting systems. These systems allow users to vote securely and anonymously without the need for a trusted third party.

These instances are just the tip of the iceberg. As technology progresses, the upcoming years promise even more groundbreaking applications made possible by smart contracts.

The Future of Smart Contracts

The future of blockchain is bright, with many large institutions and governments looking to adopt it for use in central bank digital currencies (CBDCs). However, technological advancement can be a double-edged sword. As new systems emerge, they can sometimes pose a threat to existing ones. For example, quantum computing could render some of the current blockchain cryptographic systems obsolete.

Quantum computing is a type of computing that uses the principles of quantum mechanics to perform calculations. This type of computing is much more powerful than traditional computing, and it could potentially be used to break the encryption used in blockchains.

To address this threat, researchers are working on developing post-quantum cryptography. This is a type of cryptography that is resistant to quantum computing attacks. While post-quantum cryptography is not yet widely available, it is likely to become more common in the future as quantum computing becomes more powerful.

In the meantime, blockchain developers are working to make their systems more quantum-resistant. This includes using more complex cryptographic algorithms and implementing other security measures.


Despite these challenges, the potential benefits of smart contracts are too great to ignore. Smart contracts have the potential to make our world more efficient, secure, and transparent.

In the future, smart contracts could also be used to automate a wide range of other tasks, such as voting, real estate transactions, and medical records management. The possibilities are endless.

The concept of smart contracts has come a long way since it was first proposed by Nick Szabo. The development of blockchain technology has made it possible to create smart contracts that are more secure and efficient than ever before.
