Crypto May Not Need Cryptocurrencies—Just Blockchain Technology

What if crypto’s greatest innovation isn’t cryptocurrency at all? Recent developments suggest that blockchain technology may have a future independent of the thousands of tokens it created, becoming infrastructure for traditional finance rather than its replacement. This week offered a glimpse of that future through new regulatory moves from the SEC and CFTC, alongside the launch of Circle’s new stablecoin-powered blockchain, Arc.

The SEC and CFTC Move Ahead Without Congress

Immediately after the CLARITY Act was rejected, the SEC took matters into its own hands. On September 17, 2026, it introduced the Innovation Exemption, which will exempt Tokenized Securities Venues (or TSVs) from registering as traditional securities exchanges and certain liquidity providers from registering as dealers.

TSVs are platforms that allow U.S.-listed stocks to be tokenized and traded on-chain via AMMs and liquidity pools—i.e., the Uniswaps and Raydiums of the crypto world. It’s important to note that the stocks themselves remain securities; the exemption just applies to the platforms used to trade them. This is a big deal as DeFi can now support regulated U.S. securities markets without draconian oversight. Nonetheless, there will be some oversight, as TSVs must publish data (e.g., trade sizes, volumes, timestamps, pool addresses, liquidity). The SEC can then use that data to evaluate how on-chain markets work before enforcing permanent rules.

Support came from SEC Commissioner Mark Uyeda, who describes the exemption as a way to test how tokenization could improve settlement and ownership records, and from Commissioner Hester Peirce, who believes this could potentially be the future of stock trading.

The SEC wasn’t the only agency to move after the CLARITY Act failed. On September 17, the CFTC sent a new regulatory (RIN 3038-AF80) initiative titled “Regulation Crypto Asset Transactions and Regulation Crypto Asset Markets” to the White House for review. The details have not yet been released, so we don’t know what the rules will look like. Nonetheless, the filing allows the CFTC to move forward on crypto rules without waiting for Congress.

On the same day, the CFTC also granted regulatory relief to passive trading software providers (i.e., No-Action Letter 26-25). Under Staff Letter 26-25, qualifying software providers that simply connect users to regulated trading markets will not have to register as introducing brokers. In simple terms, the CFTC is distinguishing between software that provides access to a market and a broker that actually intermediates trades.

Circle Launches Arc

The regulatory changes weren't the only sign of where crypto may be heading. On September 16, Circle launched the mainnet of Arc, a Layer-1 blockchain built specifically for financial applications. Unlike most blockchains, Arc does not require users to hold a volatile native token to transact. USDC is used to pay transaction fees, transactions reach finality in under a second, and Arc is EVM-compatible, meaning applications built for Ethereum can be deployed using familiar tools.

But Arc's most interesting feature may be its network security. Instead of using a native token and Proof of Stake, Arc currently uses a permissioned validator set running BFT consensus. Its founding validators include major institutions such as BlackRock, DTCC, ICE, Mastercard, Visa, and Standard Chartered. Anyone can build applications on Arc, but only approved validators participate in consensus.

This doesn't mean Arc will never have one. Circle has created 10 billion ARC tokens and is exploring a transition to Proof of Stake in 2027, in which ARC could eventually play a role in securing the network. But Arc's current mainnet still demonstrates something important: a blockchain can operate without requiring users or validators to hold a volatile native cryptocurrency.

Arc therefore raises a larger question about what parts of crypto actually matter. Perhaps the lasting innovation isn't the creation of thousands of new cryptocurrencies, but the infrastructure underneath them.

The Bigger Picture Of Crypto’s Use

A deeper meaning underlies these two moves. First, regulators aren’t just becoming more crypto-friendly; instead, crypto may be overtaking the financial infrastructure without ever needing to replace traditional finance. Stocks can remain stocks, dollars can remain dollars, and securities laws can remain in place, while settlement and ownership move on-chain.

This also represents a new philosophy for regulators, in which we regulate outcomes rather than technology. In other words, instead of forcing blockchain markets to comply with rules built for traditional exchanges, regulators can focus on investor protection while allowing the underlying technology to evolve.

The original cypherpunk question was whether crypto would replace the financial system. The more interesting question now may be whether the financial system itself will become crypto infrastructure. If this continues, crypto may not need to replace traditional finance at all. Traditional finance may simply become increasingly crypto-native.
