from some of the leading universities in the United States of America have
jointly conducted a very interesting exploration. They analyzed all the smart
contracts that were created in the Ethereum blockchain in 2017 and shared the
results with the general public.
set themselves the task, which was to obtain information regarding the
interaction of smart contracts and ordinary users. It was found that about 60%
of them have not been used. This fact proves a significant amount of"
sleeping code " in the blockchain.
contracts strongly resemble each other. This suggests that most developers rely
on code that has already been written by someone else a little earlier. And if
the person who was engaged in the creation of the original version of the smart
contract made a mistake, then most likely it will be saved in other similar
variations, which increases the likelihood of hacking.
there is a positive point. Over the past year, the number of average daily
transactions made using blockchain has increased by more than 25 times. The
percentage of unsuccessful transactions varies from 0.01% to 0.1%.
