Blockchain, Smart Contracts, Crypto, and Web 3.0 for Business Lawyers

This article is related to a Showcase CLE program that took place at the ABA Business Law Section’s Hybrid Spring Meeting on Friday, April 28, 2023. All Showcase CLE programs were recorded live and will be available for on-demand credit, free for Business Law Section members.

Blockchain technology has become a buzzword in the business world, and its applications are rapidly expanding. With the rise of cryptocurrencies, smart contracts, and other decentralized applications, blockchain has opened up new possibilities for businesses to operate more securely, transparently, and efficiently. This article will explore the basics of blockchain, smart contracts, crypto, and Web 3.0 and how they are relevant for business lawyers. We will also examine some of this technology’s current business, litigation, and regulatory risks.

What Is Blockchain?

Blockchain is a decentralized digital ledger that records transactions securely and transparently. It was first introduced in 2008 by an anonymous person or group under the pseudonym Satoshi Nakamoto as a core technology behind Bitcoin, the first cryptocurrency. Blockchain is a distributed database that stores information in blocks, and each block is linked to the previous one, forming a chain of blocks. These blocks are verified and validated by a network of computers, known as nodes, that work together to ensure that each transaction is legitimate and accurate.


One of the key features of blockchain technology is its decentralization. Decentralization refers to the absence of a central authority controlling the network. In traditional systems, a central authority such as a government or a financial institution is responsible for maintaining the database and verifying transactions. In a decentralized system, there is no central authority. Instead, the network of nodes is responsible for verifying and validating transactions. This makes blockchain more secure, transparent, and resilient to attacks, as it eliminates the need for a single point of failure.

Why Crypto Matters

Cryptocurrency is a digital or virtual currency that uses cryptography for security. Cryptocurrencies are decentralized, meaning they are not backed by any government or financial institution. They are created and managed using blockchain technology. The most well-known cryptocurrency is Bitcoin, which was created in 2009.

The main advantage of cryptocurrencies is their decentralization, which makes them resistant to censorship, fraud, and theft. Cryptocurrencies also offer faster and cheaper transactions compared to traditional payment methods, and they can be used for cross-border transactions without the need for intermediaries.

Smart Contracts

Smart contracts are self-executing contracts programmed to execute automatically when certain conditions are met. Smart contracts are based on blockchain technology, and they use blockchain’s decentralized architecture to enable parties to engage in transactions without intermediaries. The code that powers smart contracts is stored on the blockchain and executed automatically when pre-defined conditions are met.

Smart contracts can be used for a wide range of applications, including digital identity verification, supply chain management, and real estate transactions. They can also be used for financial transactions, such as lending and insurance, where the contract terms can be automatically executed based on predefined conditions.

Web 3.0

Web 3.0, also known as the decentralized web or the semantic web, is the next generation of the internet. It is based on blockchain technology and aims to create a decentralized and open internet. Web 3.0 will enable users to take control of their own data and online identity, eliminating the need for intermediaries such as social media platforms and search engines.

Web 3.0 will enable a wide range of decentralized applications, including decentralized finance (DeFi), decentralized social networks, and decentralized marketplaces. These applications will be built on blockchain technology and will be powered by smart contracts.

Business Risks

Blockchain technology offers many benefits for businesses, including improved security, transparency, and efficiency. However, it also comes with some risks. One of the main risks of blockchain is the lack of regulation. The decentralized nature of blockchain makes it difficult for regulators to monitor and regulate the market. This can lead to fraudulent activities and scams, which can cause financial loss to investors.

Another risk associated with blockchain is the possibility of cyber-attacks. While blockchain is designed to be secure and resilient to attacks, it is still susceptible to hacking attempts, especially at the application layer. Smart contracts, which are a key component of blockchain technology, are also vulnerable to attacks. In 2016, for example, a hacker exploited a vulnerability in a smart contract on the DAO (Decentralized Autonomous Organization) network and stole around $50 million worth of Ether.

Litigation Risks

The use of blockchain technology can also give rise to litigation risks. Smart contracts, for example, are programmed to execute automatically based on predefined conditions. If the code contains errors or if the conditions are not properly defined, it can lead to unintended consequences and disputes. In addition, the lack of regulation in the blockchain space can lead to legal uncertainty and disputes over ownership and liability.

Regulatory Risks

Regulatory risks are also a concern in the blockchain space. The lack of regulation can make it difficult for businesses to operate and raise funds. For example, ICOs (Initial Coin Offerings), which are a common way for blockchain-based startups to raise funds, are largely unregulated, and there have been many cases of fraud and scams. As a result, regulators around the world are taking steps to regulate the blockchain space, which can lead to additional compliance costs for businesses.


Blockchain, smart contracts, crypto, and Web 3.0 are rapidly transforming the business landscape. They offer many benefits, including improved security, transparency, and efficiency. However, they also come with regulatory, litigation, and business risks. As a result, businesses and lawyers need to be aware of these risks and take steps to mitigate them. This includes understanding the regulatory landscape, ensuring the security of smart contracts and other blockchain applications, and being prepared to handle disputes and litigation that may arise. With proper planning and risk management, businesses can harness the power of blockchain technology and unlock new possibilities for growth and innovation.
