Key Points

  • Cardano is increasing its block size from 72KB to 80KB. Plutus script memory cells will also be affected.
  • The update is scheduled to be released this Friday.
  • Caldano’s goal is to become more scalable this year to catch up with its Tier 1 competitors.

Cardano's core development team, Input Output, has increased the network block size by 11%. The team also plans to add memory to its smart contract platform Plutus.

Caldano aims to solve expansion problems

Caldano is increasing its block size.

Network Update: Today, we are proposing our next parameter update as we continue to increase the #Cardano network capacity as planned. The proposal increases the block size by another 8KB, from 72KB to 80KB. 🧵⤵️


In an update posted on Twitter on Wednesday, Input Output reported that it will expand Cardano's block size from 72KB to 80KB. Block size is the maximum amount of data a single block can have on a blockchain. Larger block sizes allow more transactions to be added to new blocks, thus increasing scalability.

In addition to increasing the block size, the team plans to improve the performance of Plutus, Caldano's execution platform for deploying smart contracts. The team revealed that the Plutus script memory unit will be expanded from 12.5 million to 14 million. The expanded memory limit is expected to improve the ability of Plutus smart contracts to handle more data items.

The Input Output team says these updates will "provide additional resources for Plutus scripts to improve the dApp user experience while increasing overall network capacity."

These two improvements are scheduled to go live this Friday at 21:44 UTC.

When launching the upgrade, Input Output looked to Cardano's ability to overcome its congestion issues. Notably, Input Output made a similar update to block sizes and Plutus memory cells in November 2021.

Caldano's first decentralized exchange, SundaeSwap, experienced a rough launch when users reported that high congestion prevented them from executing a token exchange. In a tweetstorm announcing the update, Input Output warned that there could still be "significant load" on the network during the expected launch of the new dApp and NFT mint. Cardano founder Charles Hoskinson has previously said that the blockchain could become a hub for DeFi and NFT, but that the network still has a ways to go to catch up with its competitors.

Throughout 2022, Input Output plans to continue optimizing Cardano as part of the "Basho" expansion phase. With this, Cardano will hope to capture market share from Ether and the various other Layer 1 networks that will dominate the cryptocurrency space in 2021.
