The Cardano development team has proposed to increase the block size in the context that this blockchain is experiencing transaction congestion problems even though there are not many applications deployed.


On February 2, Input Output (IOHK), the development team behind the Cardano blockchain, announced a proposal to increase the block size by 11% to solve the current transaction bottleneck.


Specifically, Input Output wants to expand the ADA block size from 72KB at the moment to 80KB. In addition, Cardano also proposes to increase the amount of transaction data on the smart contract platform Plutus from 12.5 million to 14 million. Both changes, if without a hitch, will be activated on the Cardano mainnet at dawn on February 5 (UTC).


IOHK asserts that these changes will both improve Cardano's transaction processing performance and help the applications running above to have no problems in operation.


These are considered the first countermeasures of the Cardano development team to the fact that this blockchain has continuously reached its limit in recent times, with most blocks being 85% - 90% or more full, as shown. Notably, Cardano showed signs of congestion even though only one notable application, the SundaeSwap DEX exchange , was launched, raising concerns that the network would not be able to withstand the volume of transactions once the Another DeFi project launching in 2022.


Up to now, the transaction congestion problem has not been resolved. SundaeSwap even posted the following message on the exchange's swap interface:


“The network is currently experiencing severe congestion. Swaps will probably fail repeatedly until the problem is resolved. Please be patient.”


According to the development roadmap, Cardano has just completed the Goguen period, which is smart contract support. Going forward, the project will enter the Basho era, which will focus on scaling solutions. Therefore, Cardano's scaling problem is inevitable.


Increasing the block size, however, will only be a short-term solution. For comparison, Ethereum's block size is also often in the range of 70KB - 90KB, but the network relies on layer-2 solutions to reduce transaction load on the main blockchain, thereby increasing the capacity. handling.


In November 2021, Cardano also increased the ADA block size from 8KB to 72KB . Until the project has a sustainable scaling solution, it is highly likely that the block size option will continue to be used by IOHK to deal with the temporary situation.
