IOHK shuts down Cardano FUD after ‘1 transaction per block’ criticism

09/07/2021

Cardano good contracts are readying for rollout in lower than every week. However, deep within the testnet section, it’s emerged {that a} “quirk” in its eUTxO mannequin might result in problems with concurrency.

What does this imply?

eUTxO stands for prolonged unspent transaction output. These methods comprise the asset, good contract, and extra on-chain information related to the good contract.

So when eUTxOs are created, they’ve the choice to have good contracts connected to them. This mannequin relies completely on particular person transactions grouped in blocks.

“What this implies is that each time you want to replace information held by a dApp (within a UTXO), you could spend the unique UTXO (thereby destroying it) and create a brand new UTXO on the identical tackle & holding the identical property.”

This operates in another way from the accounting (or stability) mannequin employed by Ethereum, whereby property are represented as balances inside accounts, much like financial institution accounts.

In computing, concurrency refers back to the capability of a wise contract to deal with requests from a number of totally different brokers on the identical time. Nonetheless, a current article by OccamFi factors out that some Plutus builders are involved that the eUTXO system employed by Cardano allows just one agent to work together with the SC at a time. Thus making a concurrency bottleneck.

“The place builders are at the moment working into an issue is with just one agent being allowed to eat the UTXO and thus the SC at a time, creating this so-called “Concurrency” difficulty.”

An instance of the place that is problematic is within the case of working a decentralized trade (DEX), the place a number of customers require entry to a contract tackle on the identical time.

Cardano responds to the FUD

In response, builders Enter Output Hong Kong (IOHK) dismissed this concern as a non-issue.

Explaining the state of affairs, they posted a tweet thread, firstly, by defending the eUTxO mannequin, saying it gives higher safety and charge predictability and “extra highly effective parallelization.”

The particular taste #Cardano makes use of is the eUTxO – or prolonged mannequin which we consider gives better safety, permits for charge predictability (no nasty surprises…) and gives extra highly effective parallelization.

Particularly addressing the purpose, they are saying their eUTxO system just isn’t bottlenecked if builders make use of a number of UTXOs. Which they are saying works to “implement” parallelism.

“And to be clear, dapps are NOT restricted to 1 transaction per block. By designing your service or utility with a number of UTxOs, you’ll be able to implement extra parallelism. That is inherent and – we consider – one of many benefits to eUTxO design as we now have applied it in #Plutus.

Up-and-coming Cardano DEX SundaeSwap set the file straight by saying the concurrency downside solely impacts protocols that enable a number of individuals entry to the identical UTxO.

However Cardano is able to working a number of UTxOs, which nullifies the problem.
