Permissioned EVM (Ethereum Virtual Machine) blockchains are
gaining popularity as viable options for permissioned blockchains.
However, scalability and privacy remain significant challenges. This
article examines the advantages, disadvantages, and risks of current
privacy solutions for EVM- based blockchains. It concludes that the best
approach is to implement a network topology that ensures sensitive
data never leaves the institution responsible for its management. By
doing so, organizations can benefit from the advantages of blockchain
technology while minimizing the risks associated with privacy breaches.
