The software platform Cardano has entered the third stage of its roadmap, the Basho era. It promises to improve the network’s performance and scalability.
Cardano’s roadmap is “a summary of Cardano development” divided into five eras to deliver improvements in diverse functionalities of the network that are “delivered across multiple code releases”.
Now that the platform’s core smart contract capability Plutus has been deployed, the launch of the Basho era focuses on scaling Cardano, promising “Parameter adjustments, improvements, enhancements and other innovations” supposed to increase the network’s capacity.
They also call it “an era of optimization”, promising to enhance the performance and interoperability “to better support growth and adoption for applications with high transaction volume.” It is supposed to bring high performance, resiliency, and flexibility to the network.

Scalability And Interoperability
Scalability and interoperability are some of the main solutions that Cardano wants to offer as the “ethereum killer”. While the Ethereum network is working to handle up to 100,000 transactions per second (tps), Cardano plans to reach millions of tps through the second-layer solution Hydra.
On the interoperability’s side, the Basho stage will introduce the sidechains, “new blockchains, interoperable with the main Cardano chain”, which eventually intends to allow the blockchains, with different architectures and codes, to be able to communicate: interoperate.
The Cardano Roadmap explains that “Sidechains can be used as a sharding mechanism by off-loading work from the main chain onto a sidechain to increase the capacity of the network. They can also be used to introduce experimental features without affecting the security of the main blockchain.”
Similarly, this stage will also introduce parallel accounting styles: “the ability to support and switch between UTXO and account-based models will be added using sidechains.” This is also meant to enhance interoperability and “support new kinds of use cases on the network.”
“Building on these foundations, and steadily increasing capacity and throughput to deal with the growth in the DApp ecosystem and onboard first hundreds of thousands, then millions of new users. From DeFi degens to citizens of developing nations.”
Cardano has been widely criticized for its slow start. Many people thought the platform was lagging behind, noting it took a long time to deploy its first smart contract. However, the CEO of the Cardano Foundation Frederik Gregaard argues that they take a careful approach to launch functions, with rigorous testing and peer review.
This time around, the Basho stage’s launch report noted that they expect “periods of high demand, network congestion at times”, but they see it as part of the ‘journey’ and added that they will be maintaining a “considered, safe approach”.
“We’re on an exciting journey and usage will be high. While we may at times feel impatient, this is the way. Here’s how we will optimize and scale as we grow.”
What The Basho Era Promises To Solve
The optimization and scalability improvements have been divided in the report between “on-chain solutions” and “off-chain solutions”. Here is what they intend to solve:
For on-chain solutions:
- Block size increase: the network recently increased the block size by 12.5% to 72KB and “further increases will be applied over time”.
- Pipelining: intends to propagate blocks “to at least 95% of peers within five seconds” to provide “the headroom to make more aggressive scaling changes”.
- Input Endorsers: “This improves the consistency of block propagation times and allows higher transaction rates.”
- Memory /CPU parameters for Plutus: improves the efficiency of memory usage across the chain.
- Plutus script enhancements: a “more effective usage of the powerful EUTXO model through smart contract optimization,”
- Node enhancements: intends to “help even distribution of stake and reward computations across the epochs”. The new node version “reduces peak load at critical points,”
- On-disk storage: “RAM-constrained systems will be able to run nodes (…) and memory will no longer be a bottleneck on scalability.”
For off-chain solutions:
- Sidechains: “Assets can be moved between chains as needed.”
- Hydra: “provides a more efficient means to process transactions off-chain,”
- Off-chain computing: “Transactions occur outside of the blockchain itself, yet can offer fast, cheap transactions via a trust model.”
- Mithril: results in “Multi-signature aggregation that is fast and efficient without compromising security features.”
