Blockchain technology revolutionized data recording and sharing, and smart contracts emerged as a promising addition to this landscape. Smart contracts provided a new perspective on automation, enabling self-executing pieces of code to execute transactions based on pre-defined conditions. However, as the technology evolved, the limitations of smart contracts 1.0 became apparent, leading to the concept of Smart Contracts 2.0. This new generation of smart contracts offers advanced functionalities and opens up new opportunities for developing programmable digital assets. Hedera has taken the initiative to introduce Smart Contracts 2.0, and this guide provides an introduction and a deep dive into the latest updates about this technology.

 

Definition of Smart Contracts

Smart contracts are digital versions of traditional contracts that specify the conditions of an agreement. What sets them apart and makes them ‘smart’ is the use of blockchain technology, eliminating the need for intermediaries in contract execution. Smart contracts use code on a blockchain network to establish, verify, and execute agreement terms. They represent arbitrary deterministic business logic in code, working on a distributed system with decentralized governance to ensure fair and unbiased execution.

 

Why Does the Blockchain Ecosystem Need Smart Contracts 2.0?

The blockchain ecosystem needs Smart Contracts 2.0 to address the limitations of existing Smart Contracts 1.0. While Smart Contracts 1.0 had a significant impact on the adoption of blockchain for various applications, they suffered from slower transaction confirmations, operational predictability issues, and higher operational costs. Vulnerabilities in smart contract code also led to losses due to hacking attacks. The need for improved functionalities and security has given rise to the concept of Smart Contracts 2.0.

 

Limitations with Smart Contracts 1.0

Smart Contracts 1.0 faced setbacks like slower transaction confirmation, operational predictability issues, higher costs, and vulnerabilities in the code leading to hacking attacks. The high-profile hacking incident of the Poly Network, resulting in the theft of cryptocurrencies worth $613 million, highlighted the security issues in existing smart contracts.

Definition of Smart Contracts 2.0

Smart Contracts 2.0 is the next stage in the evolution of smart contract technologies, building upon the concepts of Smart Contracts 1.0. It leverages modern technologies like oracles, IoT, and artificial intelligence to offer multiple advantages over existing smart contracts. Smart Contracts 2.0 can handle complex tasks, access external data sources through oracles for better decision-making, offer enhanced security with advanced encryption algorithms, and settle transactions almost in real-time with lower gas fees. They also provide better scalability and interoperability, allowing blockchain networks to communicate and facilitate cross-chain asset transfers.

 

Working of Smart Contracts 2.0

Hedera Hashgraph is the first distributed ledger technology platform to introduce Smart Contracts 2.0. It aims to upgrade the Hedera Smart Contracts Service to achieve significant improvements in performance metrics. Hedera plans to scale the Ethereum Virtual Machine (EVM) to improve transaction speeds, offering up to 13 times faster transaction processing than the Ethereum mainnet. Hedera does not follow the concept of blocks and timestamps, ensuring fair distribution of transaction order, accessibility, fees, and timestamps. It also addresses issues like frontrunner attacks, making it an ideal ecosystem for expanding DeFi projects and financial markets.

How Does Hedera Offer the Advantages of Smart Contracts 2.0?

Hedera offers several advantages with its smart contracts 2.0. It ensures fair transaction distribution without block confirmation, improves security with an asynchronous BFT consensus mechanism, and has a positive impact on the environment with carbon-negative operations. Additionally, Hedera smart contracts 2.0 allow customized programmability by integrating traits of Hedera Token Service and Hedera Consensus Service. This integration empowers smart contracts to call native HTS functions, facilitating functionalities like minting, transferring, burning, and associating with HTS.

Where Will You Use Smart Contracts 2.0?

Smart Contracts 2.0 have numerous use cases, with DeFi being a major one. They enable users to trust code and governance mechanisms instead of relying on intermediaries like banks. Another use case is the Creator Economy-centric application, Galaxy, which uses smart contracts to manage social tokens and underlying collateral. Smart Contracts 2.0 can also accept deposits in stablecoins and other recognized methods for collateral, providing more flexibility in minting or burning social tokens.

 

Long-term Implications of Smart Contracts 2.0

Smart Contracts 2.0 have far-reaching implications, offering high throughput, better security, and stable governance. In complex scenarios like decentralized exchanges, smart contracts can manage order books, and the Hedera Consensus Service provides verifiable data logs. Smart Contracts 2.0 on Hedera facilitate the creation of high-performance applications and digital-native real-world assets. With improved efficiency, security, and scalability, smart contracts 2.0 can transform the blockchain landscape and empower the next generation of DeFi protocols.
