Blockchains Aren't Fungible, But Cryptocurrencies Are

By Allen Taylor | Cryptocracy | 4 Jul 2022

There seems to be some confusion in certain circles about the meaning of fungibility with regard to blockchain technology. I will try to clear that up.

Fungibility does not mean that one can exchange a crypto unit from one blockchain with another. One bitcoin does not equal one litecoin. That doesn’t mean that one can’t be traded for another, but the trade is simply that—a trade.

Blockchain technology is a wonderful thing, but it has its limitations. As long as we all agree on that, we can have great discussions. But I’ll draw an analogy between the blockchain and a field. When a farmer plows his field and readies it for a new crop, he doesn’t consider the field to be his product. Whether he plants corn, soybeans, or wheat, those are his products.

With regard to fungibility, one could take an ear of corn from the farmer’s harvest, take it to another man’s farm, and trade it for another ear of corn. Same product, same value. The corn is not fungible with soybeans, but the farmer could trade some corn for an equal value of soybeans. Cryptocurrencies are similar to these farming products.

Bitcoin has its own blockchain. On that blockchain, there is one crop: Bitcoin. Ethereum, on the other hand, has many crops—called altcoins. ERC-20 tokens. Ethereum is the primary crop, but there are a variety of tokens minted on the same chain. None of them are fungible with bitcoin, nor are they fungible with each other. They can be traded, but the essence of fungibility is that you can take any one of those ERC-20 tokens and trade it for another of the same ERC-20 token because they have the same value.

This basic feature of blockchain technology, the ability to mint cryptocurrencies that are not fungible with each other but are fungible with the same cryptocurrency minted on the same blockchain, is embedded in the technology. It’s not a bug.

This feature is the reason both the SEC and CFTC chairs consider bitcoin and ether to both be commodities. They act like commodities. Therefore, they are commodities. I believe the law will soon recognize that.

That’s why I would extend the call to freedom beyond bitcoin to all cryptocurrencies. That doesn’t mean that all crypto is created equal, nor does it mean that all cryptocurrencies have the same value. But choice in the monetary market is the best way to ensure that freedom wins long term, and not just in America.
