The Cardano blockchain is developing the Leios upgrade to significantly increase transaction throughput, with the goal of reaching performance levels comparable to the XRP Ledger (XRPL), according to technical roadmaps and updates from Input Output Global (IOG).
The Leios initiative focuses on optimizing the way the network propagates and processes blocks, aiming to resolve bottlenecks that have historically limited Cardano’s transactions per second (TPS). By improving the efficiency of block delivery, the upgrade seeks to reduce latency and allow the network to handle a higher volume of concurrent users and smart contract executions without compromising decentralization.
This scaling effort arrives as Cardano transitions into the Voltaire era, focusing on governance and sustainability. The push for “XRP-like” speed is a strategic move to make the network more attractive for institutional finance and high-frequency decentralized applications (dApps), which require the near-instant finality characteristic of the XRP Ledger.
How the Leios Upgrade Increases Cardano’s Speed
Leios targets the “block propagation” phase of the blockchain process. In a distributed ledger, every node must receive and verify a new block before the next one is added. If the time it takes for a block to travel across the global network is too high, the network must slow down its block production to avoid forks or instability.
According to IOG, the Leios upgrade implements a more efficient method of data transmission. Instead of sending entire blocks in a linear fashion, the system optimizes how data is fragmented and distributed across the network. This allows nodes to synchronize faster, effectively shortening the time between blocks and increasing the total number of transactions the network can process per minute.
The technical shift is designed to move Cardano away from its current constraints and toward a high-throughput environment. While Cardano has traditionally prioritized a slow, peer-reviewed approach to updates, the Leios framework represents a more aggressive push toward scalability to compete with other Layer 1 blockchains.
Comparing Cardano’s Goals with the XRP Ledger
The XRP Ledger is widely recognized for its speed and low cost, capable of handling approximately 1,500 transactions per second with settlement times typically under three to five seconds. In contrast, Cardano’s current throughput is significantly lower, often fluctuating based on network congestion and the complexity of smart contracts being executed.
By benchmarking against the XRPL, Cardano developers are targeting a shift in user experience. For a global payment system or a complex DeFi ecosystem to function, transactions cannot take minutes to confirm. The Leios upgrade aims to bring Cardano’s finality closer to the sub-second or few-second range, making it a viable competitor for cross-border payments and real-time asset transfers.
Industry analysts note that while the XRPL achieves speed through a consensus mechanism that does not rely on mining or traditional staking, Cardano must achieve similar results while maintaining its Ouroboros Proof-of-Stake (PoS) architecture. This makes the Leios optimization critical, as it must increase speed without centralizing the network around a few high-powered nodes.
Integrating AI Agents and Visualizing the Blockchain
Parallel to the technical upgrades of the core protocol, new initiatives are emerging to make Cardano’s complex mechanisms more accessible. Some developers are implementing visualization layers that translate blockchain data into a retro-futuristic 2D city environment. In these simulations, AI agents act as representatives of different blockchain functions, such as validators or smart contract executors.
This visualization is not a part of the Leios protocol itself but serves as an educational and operational interface. By turning abstract data—like block height, stake pool distribution, and transaction flow—into a visual city, users can better understand how the network operates in real-time. The use of AI agents within these environments allows developers to simulate network stress and test how the Leios upgrades handle traffic spikes before they are deployed to the mainnet.
These tools are intended to lower the barrier to entry for non-technical users and investors, providing a tangible way to monitor the “health” and speed of the network as the Leios upgrades are phased in.
What Happens Next for Cardano Scalability
The rollout of Leios is expected to be incremental. Following the successful implementation of the Chang hard fork, which introduced on-chain governance, the community and IOG will move toward these scaling enhancements. The process involves rigorous testing on the Preprod and Preview testnets to ensure that increasing block speed does not lead to network instability.
Stakeholders are monitoring the official Cardano Interop and IOG updates for the specific deployment dates of the Leios components. The next major milestone involves the refinement of the “input endorsers” and other scaling mechanisms that will work in tandem with Leios to maximize the network’s capacity.
As Cardano moves closer to matching the speed of the XRP Ledger, the focus will likely shift from theoretical capacity to actual adoption. The success of Leios will be measured by whether high-volume enterprises migrate their operations to the network once the throughput barriers are removed.
