Smart Contracts: A Tutorial

Smart contracts are blocks of code that reside on the blockchain. It is like an Ethereum account but there is a critical difference between an external account and a smart contract. Unlike a smart contract, an external account can connect to multiple Ethereum networks Rinkebey, Kovan, main, etc. When a smart contract is deployed, it creates an instance contract account on the network.

In this network, anyone can transact, view the history of transactions, or create and join a peer node to the network to help maintain it. An example of a permissioned network is a known consortium of banks and export houses looking to perform cross-boundary transfer of assets for example, letters of credit with each other. This example network works without a centralized authority acting as a liaison. For more information about blockchain, see the Blockchain on AWS webpage.

These contrast with central bank digital currencies CBDCs and stablecoins, which are digital representations of fiat currency. Their value is derived from an actual currency in circulation, and they are issued by a central bank. Equity and derivative tokens are digital assets whose value may represent actual corporate stock or a legal right to another asset or financial instrument. Some digital assets have additional attributes, such as voting rights on a protocol, or they may provide a level of access for participation in a decentralized application.

These may provide some commercial or economic benefit to the holder. Prior to investing in any digital asset, it is important to understand the specific terms, conditions, and characteristics of the investment since those will affect accounting, tax, risk, controls, and legal considerations, among others.

What follows here, then, is some guidance on what undergirds any corporate decision to invest in digital assets like Bitcoin. In addition, we set out the ongoing actions that teams across a company should undertake to monitor and go forward with a long-term investment. Before proceeding, we want to make one point absolutely clear: There is no playbook or foolproof approach for these kinds of bold moves.

There is only painstaking effort, disciplined analysis, fresh thinking and rethinking, dedicated collaboration across competencies, and, above all, rigorous execution.

What follows, then, is not a step-by-step prescription, but instead a high-level guided tour of the wide terrain companies should cover when they are considering investing in Bitcoin. Additionally, note that what is stated here cannot necessarily be extrapolated to all digital assets, given that they have many different characteristics.

Typically, the various functions and departments of a company establish procedures and assumptions for collaborating across and outside the organization based on normal-course, well-understood transactions.

The terrain of digital assets is a new frontier of possibilities, so it requires that each corporate department, and its external party, rethink the application of the rules and policies of its core competency. Few of the norms associated with legacy investments in securities, fiat currency, or treasuries may apply.

Once each group gains a level of comfort with the application of the rules to digital assets, they then need to actively listen to one another, gain an understanding of the sensitivities, evaluate any operational or technical dependencies, and finally rethink how they collaborate and tackle challenges together. Many more operating companies are beginning to evaluate the potential benefits of investing in digital assets like Bitcoin.
