O(1) Labs Operating Corp., the parent company of the Coda Protocol, has raised $15 million in new funding to continue to build out its tiny blockchain.

The Series A funding round included Accomplice, Coinbase Ventures, Paradigm and General Catalyst, along with previous investors MetaStable, PolyChain and Electric Capital.

Founded in 2018, the Coda Protocol is attempting to build a “tiny portable blockchain” that swaps out a traditional blockchain for small cryptographic proof that in theory should make cryptocurrencies more usable.

It is doing so by compressing blocks and providing “zero-knowledge” proofs, resulting in blockchains that are often only as large as “a few tweets,” according to Coda, versus sometimes terabytes of data with existing blockchains. Notably, in shrinking the size of the blockchain, security is not compromised.

“Full verification of the chain is available to any device, and participating in consensus is highly accessible,” Coda said in a blog post Tuesday. “And even better, as the proof is constant sized, using Coda stays inclusive and decentralized even at millions of users, thousands of transactions per second and with decades of history.”

Coda’s small size also delivers additional benefits, including the ability to be used on websites without requiring an extension and from mobile phones with intermittent connectivity.

“Developers will be able to reach users simply by dropping in a <script> tag into their frontend and writing a few lines of code, without requiring users to download extensions or trust any third parties,” the developers claim. “By taking advantage of this, developers will be able to build new websites and applications impossible in today’s world.”

The group launched its first test network in September and is charging ahead, eventually planning on launching their own cryptocurrency. When, though, isn’t clear, with Coda only saying that more details will be available in the coming months.
