Digital assets are subject to a number of risks, including price volatility. Transacting in digital assets could result in significant losses and may not be suitable for some consumers. Digital asset markets and exchanges are not regulated with the same controls or customer protections available with other forms of financial products and are subject to an evolving regulatory environment.

Smart contracts are computer programs that automatically execute the terms of a contract between parties, and there is a new version of them: smart contract 2.0.
In recent years, the concept of smart contracts has evolved beyond simply executing predetermined terms to include more dynamic capabilities that support new types of decentralized applications. This evolving model is now commonly referred to as "Smart Contracts 2.0."
In this article, we will explore the basics of smart contracts, provide examples of how they work, discuss how blockchain 2.0 enables their enhanced functionality, and examine the exciting potential applications of smart contracts going forward.
A smart contract is a computer program or piece of code that is designed to automatically execute "if/then" statements or obligations of a contract. As a way to digitally facilitate and enforce agreements between parties, Nick Szabo first proposed them in the middle of the 1990s.
Smart contracts use blockchain technology to function as decentralized applications (dApps) that run exactly as programmed without any possibility of downtime, censorship, fraud, or third-party interference.
For example, a smart contract could automatically execute the exchange of digital assets, like crypto exchanges, between users according to specific predetermined conditions in the contract code.
Therefore, it could be used to build an insurance smart contract that pays out a policyholder's beneficiaries automatically upon criteria in the code being met. This removes the need for human claims adjusters and provides instant settlement of life insurance proceeds.
Other examples of applications include automatically paying rent, tracking supply chains, settling financial crypto derivatives, or performing any task that involves an "if this, then that" scenario. A euro stablecoin, EURK offers transparent transactions that are fast, secure, and easy.
As decentralized applications, smart contracts must operate on blockchain networks to function. Blockchains' immutability and transparency make it possible for smart contracts to run automatically according to the rules they are programmed to follow.
This feature eliminates the risk of being censored or going down. The decentralized and censorship-resistant nature of blockchains ensures smart contracts execute as agreed, regardless of other changes that may occur.
Blockchains thus provide the ideal infrastructure to reliably support the automated execution of digital agreements through smart contracts. Cryptobunq, a secure crypto service provider, issues and audits EURK securely.
The first generation, or "Blockchain 1.0," platforms lacked many of the features needed to fully realize the potential of smart contracts. The blockchain platforms of "Blockchain 2.0" have evolved to enable more powerful smart contract capabilities through new technologies and protocols.
For example, Ethereum introduced the Ethereum Virtual Machine, which allowed Turing-complete smart contracts to be written in different programming languages like Solidity and Vyper. Blockchains are also adopting off-chain solutions to improve scalability for running more complex contracts.
Technologies like state channels, plasma frameworks, privacy protocols, and oracles also support dynamic smart contract use cases beyond simple if/then statements. This also protects smart contracts against reentrancy attacks.
As mentioned in a study by Grand View Research, Blockchain 2.0 thus brings improvements that allow for "decentralized applications that can enable complex applications like decentralized organizations or value exchanges like cryptocurrencies built upon a blockchain network."
Blockchain 2.0 effectively provides the necessary foundation for Smart Contracts 2.0 and their advanced capabilities. A securely audited stablecoin like EURK, which has reserves in multiple banks, empowers innovation with reliability and efficiency through blockchain-powered solutions.
While first-generation smart contracts allowed for basic conditional statements to be programmed, Blockchain 2.0 requires more versatile smart contract applications in order to reach its full potential.
“Smart contracts that can enforce complex decision logic, interact with off-chain systems, and coordinate activities across many entities over long periods of time” were written about in a PLOS One study.
To achieve real-world use, contracts need to interact with off-chain data sources, coordinate with third parties, and evolve based on external conditions.
For example, in supply chain management, contracts may need to interact with IoT sensors, quality reports, weather forecasts, and other systems to dynamically adjust the routing and handling of goods.
Blockchain business networks thus depend on the kinds of advanced smart contract functions that Smart Contracts 2.0 aims to provide. Flexible, evolving contracts are also important for enabling novel decentralized business models, services, financial products, and more to be built on blockchains.
Overall, Smart Contracts 2.0 represents an important evolution for reaching blockchain's vision of open, distributed ledger systems.
As smart contract capabilities continue to mature, their potential future applications are vast across virtually all industries that involve trusted transactions, agreements, or record-keeping between parties. Some of the most promising areas to utilize Smart Contract 2.0 functions include:
As blockchain technology expands, new applications are being developed using examples of smart contracts like the management of donations to ensure funds are properly distributed by charitable organizations.
As smart contracts in blockchain become more full-featured, the possibilities for innovative new dApps across every sector are likely to continue to expand.
Looking ahead, the future of smart contracts appears bright as the technology evolves and finds applications in more industries. Research predicts the global smart contract market could reach over $14.6 billion by 2029, according to Zion Market Research.
As blockchains evolve into enterprise-grade distributed ledger platforms over the next five to ten years, smart contracts are positioned to play a vital role in managing distributed applications and business processes.
Smart Contracts 2.0 will reach its full potential when it gets better at flexible programming, working with other networks, and connecting to off-chain systems using oracles and devices.
Smart legal agreements, licensing capabilities, decentralized autonomous organizations, and innovative new services built on blockchains are set to transform business models and shift paradigms across many sectors through the rise of Smart Contracts 2.0.
Smart contracts no longer just have conditional functions that are clearly defined. They now have more flexible features that allow for more complex, distributed applications.
Blockchain 2.0 effectively provides a strong technical foundation for Smart Contracts 2.0 and promises to deliver diverse benefits across industries through platforms like Ethereum.
With continuous improvements, the future applications and potential impact of decentralized smart legal agreements and services appear vast. Smart Contracts 2.0 represents an exciting phase of innovation for blockchain technology.
