One study notes that most smart contracts in Ethereum are copies of other contracts

According to a study conducted by Northeastern University and University of Maryland academics, published Oct. 31, the lack of diversity of smart contracts (ETH) poses a threat to women. ecosystem of the Ethereum blockchain.

In the 6-page document titled "Ethereum Contracts Topology Analysis", Examine how contracts are created in Ethereum and how users and contracts interact with each other.

Academics have found that today 's contracts are three times more likely to be created from other contracts. In other words, most of Ethereum's smart contracts are "direct copies or almost any other contracts". In fact, less than 10% of contracts are unique.

This poses the terrible risk that many contracts will be created from vulnerable or erroneous contracts.

In addition, another finding is that they have not interacted with more than 60% of the network's contracts.

On the other hand, research has indicated that there is a re-use of the code in Ethereum, which could have a "widespread impact on the Ethereum user population", although there is some evidence that there is a potential impact on the Ethereum user population. it is also "a driving force of Ethereum's success". .

Supported in part by the US National Science Foundation, this study analyzed Bytec codes for Ethereum Smart Contracts in its first 5 million blocks, covering a three-year period; since the beginning of cryptocurrency in 2015.

The investigation concluded that the "multiple implementations of"central functionality of the contract"In Ethereum, they would eventually provide" greater defense "to the entire Blockchain.

Remember that Ethereum is the second most valuable cryptocurrency today, with a current market capitalization of more than $ 68 billion and a price that fluctuates to $ 200.
