Cardano Head explores Delimited Continuations: What is it?

Cardano co-founder Charles Hoskinson excited the crypto world by dropping just a hint at the possibility that limited continuations could be executed on the Cardano blockchain in 2025.

Earlier this month, on December 22, Hoskinson said 2025 will be the year of the ADA. Many crypto enthusiasts now believe that limited continuations could be the new technological addition the co-founder hinted at. Although such a sentence may seem too harsh to consider, its effects may indeed reflect a legitimate impression about the implementation of Cardano (ADA) and the results of its developments and investments.

What are restricted continuations?

Bounded continuations are a programming construct that allows the programmer to suspend an ongoing calculation and resume it at a later time. ADA has the potential for increased performance and customization in the execution of smart contract programs designed to perform actions fully automatically under certain conditions.

Last night I had a two hour discussion about adding capped continuations to Cardano. Any opinions?

Hoskinson brought into focus two important use cases of bounded continuations for the ADA ecosystem. First, they can allow differentiation of on-chain (stored on the blockchain) and off-chain (external) computations in zero-knowledge proofs, which was extremely important for the Cardano project Midnight. Second, they can make smart contracts easier to write and execute by providing a new way of thinking about classical state machine architectures.

Why is this important for Cardano investors?

This discovery for investors means that ADA is innovating in the blockchain space. Developing smart contract capabilities like the one Hoskinson focuses on dovetails with the broader goal of achieving more decentralized applications on the platform. A more developer-friendly platform could increase adoption, which could lead to increased demand for the native cryptocurrency ADA.

But there are also difficulties. Hoskinson, speaking on behalf of his company, said limited continuities were not an easy thing to implement. ADA uses the Plutus smart contract platform, whose computational rules are stricter than Haskell’s. Hoskinson says this can increase development costs and time, thus delaying expected benefits for investors.

The problem is that while Haskell is a lazy language, Plutus is strict. This greatly complicates actual implementation. Thanks to Alexis’ hard work, we have DC support in Haskell since GHC 9.6. @tweagio.

I suspect we can use freer monads as a path to DC support. IT…

What does the Cardano community think?

This crypto community is already throwing its weight behind. Developers like @bitcodyy at X see limited persistence to optimize complex calculations, providing flexibility to DApp developers. Others are very wary of its unintended consequences, namely higher costs or problems with maintaining decentralization.

Limited continuations in Cardano will open up some fascinating possibilities for optimizing complex calculations and increasing smart contract flexibility. I’m curious, what were the specific use cases or challenges driving the discussion?

What’s next for Cardano?

For new investors, the answer is clear: ADA may remain ahead of its time. All this research on bounded continuations proves blockchain’s desire to at least remain parallel with platforms like Ethereum, as Ethereum has the upper hand in smart contract implementation.

It remains to be seen whether these innovations will work, but for someone looking to invest in a blockchain technology that will interest them in the long term, Hoskinson’s vision for Cardano makes this a project to keep a close eye on.

Meanwhile, developments and limited continuations surrounding Cardano’s zero-knowledge sandbox solution Midnight could impact the future of the platform’s ecosystem. The success or failure of Cardano’s pursuit of these cutting-edge ideas will likely determine its place in the crypto market in the coming years.
