What ought to governments contemplate when getting concerned with blockchain?

Final September, Principal Safety Engineer Dr. Evan Sultanik was on a panel hosted by the Naval Postgraduate Faculty’s Distributed Consensus: Blockchain & Past (DC:BB) motion, the place college and college students there are searching for alternatives to be taught and share information, analysis, funding, and occasions centered on distributed consensus applied sciences.

The panel of 9 authorities, academia, and trade specialists mentioned how blockchains, digital property, and different Web3 applied sciences intersect with nationwide safety challenges. Dr. Sultanik mentioned how the U.S. may assist push world adoption and take a broader strategic outlook towards blockchain and Web3 applied sciences.

He talked concerning the inherent limitations of blockchain applied sciences and the Web3 motion and likewise supplied solutions from a coaching perspective that would result in a extra sturdy ecosystem. We’ve summarized an important elements of that dialogue right here.

What are the some vital issues to think about when utilizing blockchain applied sciences for a undertaking?

It’s elementary to raised perceive the tradeoffs one should make when utilizing a blockchain and its safety implications. Everybody at this level is conscious that utilizing a blockchain has vital extra overhead when it comes to deployment and the price of interacting with good contracts. The associated fee step by step decreases with the transitions to the brand new types of consensus and higher-level protocols, however there’s nonetheless a major distinction.

You must notice that every one knowledge saved on a public blockchain is publicly accessible. Anybody can look via the whole historical past of every account or contract and perceive the implications of these actions. You want to do one thing extra to make sure its privateness if that’s a requirement of your system.

Nearly all of contributors in a public blockchain are untrusted. You’re shifting belief from what would in any other case be a government to different entities that you could be or might not have management over. You’re not solely trusting the builders of the good contracts that your system is interacting with, however you’re additionally inherently trusting the builders of the know-how stack working that individual blockchain. You’re trusting the node software program, the mining {hardware}, the mining software program, the mining pool protocol, and every little thing else down the road. A bug in anybody piece of that stack may cause the entire thing to break down.

Blockchains enable builders to prototype new concepts shortly. You don’t have to fret about issues like establishing infrastructure, and also you don’t have to fret a lot about DevOps as a result of that’s all dealt with by the blockchain itself. That permits you to considerably cut back the time between when an concept is created and when it’s within the customers’ palms. However that cycle additionally comes with danger as a result of a decent improvement cycle can result in poorly examined or designed protocols or sloppy improvement, resulting in bugs with vital penalties, like being an enormous goal for attackers.

One other factor that makes DeFi, blockchain, and Web3 so interesting is that you would be able to prototype shortly and immediately join your software to the entire ecosystem. Because the blockchain acts as an enormous shared database, contracts and property created by opponents could be made to work together with one another in ways in which can be disincentivized if applied on a conventional centralized platform.

This composition does come at a worth. It’s tough to cause concerning the system since you instantly should perceive all of the completely different contracts that created these tokens. It’s completely different code in every case. And your code instantly interacts with the entire universe of code on the blockchain. So, you have to be conscious of all these different externalities and third-party elements your app may work together with.

We’ve seen this complexity play out not too long ago with new forms of monetary devices and know-how which have turn out to be accessible, notably on Ethereum, similar to flash loans or most extractable worth, that are actually deep technical ideas. Nonetheless, thousands and thousands of {dollars} have been misplaced as a result of a bunch of various DeFi apps are composed in a single transaction in a means that none meant to be composed.

Laptop scientist Leslie Lamport wrote in 1987, “A distributed system is one in which the failure of a computer you didn’t even know existed can render your computer unusable.” That is nonetheless true at this time and can all the time be true in blockchains.

Ought to the U.S. care about blockchain applied sciences, and in that case, what’s the most effective software for the federal government?

It’s a matter of nationwide safety that the U.S. authorities will get concerned with blockchains: Apart from maybe misplaced tax income, Uncle Sam doesn’t actually care when you lose your Bitcoin. However Uncle Sam ought to care if North Korea steals it. U.S. adversaries are already exploiting these applied sciences to avoid sanctions and undermine our markets.

It’s extra productive to ask, “Can blockchain and Web3 technologies ever be made secure? If so, how?” The U.S. authorities must foster analysis and innovation to reply this query to remain related and stay a world chief in distributed ledger know-how.

How ought to the U.S. deal with the coaching routine wanted within the Web3 area?

There’s a giant want to alter how we educate the incoming workforce as a result of conventional software program improvement experience doesn’t immediately translate into Web3. I’ve buddies who don’t have a background in pc science, but they discovered one programming language, wrote a cell app, and are actually millionaires. They don’t have any technical information of what a telephone is doing, how iOS or Android is working, or how the {hardware} works. They simply wanted to know that one programming language, and that was adequate for them to construct one thing very talked-about and efficient.

That isn’t true for Web3. Figuring out the whole stack is useful when creating good contracts, as a result of it’s good to perceive the compiler that you simply’re utilizing. You want to perceive the digital machine that’s working. You want to perceive byzantine, fault-tolerant, and consensus protocols. You must perceive zero-knowledge proofs or zk-SNARKs. You must perceive all of those esoteric applied sciences, and only a few specialists know any of them, not to mention all of them. You want to be an professional in them to keep away from all of the pitfalls and footguns.

We’d like insurance policies incentivizing folks to enter the workforce with these obligatory expertise. At Path of Bits, we’ve developed a blockchain security apprenticeship as a result of discovering folks with all the required expertise is tough on this aggressive market. Some safety folks know the right way to analyze a C++ program or a cell app, however they do not know about blockchain. After which you will have blockchain individuals who haven’t any background in safety. So we developed this in-house program.

For cell app shops, there has all the time been a low barrier to entry for folks trying to become involved within the app financial system. With Web3, that doesn’t appear to be the case, but there may be a number of exercise on this area. What extra must be finished to convey builders to a degree the place blockchain is mature from a safety perspective, and what entities or organizations ought to lead that effort?

The barrier to entry is surprisingly low for Web3, too, which is a part of the issue: Web3 improvement toolchains have been modeled after acquainted toolchains from conventional app improvement. Developer friendliness has been prioritized on the expense of safety. We have to modernize and enhance the tooling to flip the stability of that prioritization.


It’s not sufficient for governments to solely specific curiosity in securing blockchain applied sciences. Actual, purposeful investments must be made. Past the design of safe architectures, languages, compilers, and protocols, these investments must also embody educating a sturdy workforce to satisfy tomorrow’s Web3 calls for.

For those who’re contemplating whether or not a blockchain may be the answer to an issue you’re making an attempt to resolve, we advocate our operational danger evaluation titled, “Do You Really Need a Blockchain?” This provides you with a radical look into the benefits and dangers chances are you’ll be taking.
