Ethereum co-founder Vitalik Blerin outlines a broad plan to enhance the privacy of the network he helped create.
On an April 11 roadmap, Blerin beat Integration of privacy tools In ether (ETH) wallets and implementing privacy enhancement standards and features in the Ethereum ecosystem and protocol. He explained that the roadmap in question is a short-term solution that requires limited changes to the base protocol along with long-term updates.
Buterin recommends adoption of privacy improvement systems such as railroads or privacy of existing wallets, according to the plan. When the funds are sent along with those wallets, he says users should greet an option to “send from the shield balance,” which does not identify the transaction, and should “perfectly default default.” He wrote:
“Users should not download a separate ‘privacy wallet.'”

Basic Changes Recommended for Defi
Buterin even recommends in -depth changes to how decentralized finances (DEFI) and greater decentralized applications (DAPP) are implemented. He argued that those systems should be limited to “one address per application.”
The Ethereum co-founder has recognized that it will need “significant sacrifices of comfort,” but it is the most practical way to eliminate public links between all your activity in various applications. “He also featured that the user experience would be” similar “to depositing funds in one chain from another of crosschain’s interoperability systems.
Buterin also featured that in order to enjoy the benefits of this change, developers will need to ensure that the user’s removal functions are preserved by privacy default.
Ethereum protocol changes required
Other changes included are the implementation of FORK-CHOICE ENFORCED INCLUSION LISTS (FOCIL) And the Ethereum improvement proposal (EIP) 7701. The latter is an improvement in Ethereum Account abstractionAnd the former is an improvement in censorship resistance.

EIP-7701 ensures that privacy protocols can work without the need for relays or public broadcasters. In turn, it simplifies the development and maintenance of this type of protocol.
Relays, in this context, are mediators or nodes responsible for receiving and passing transactions. On the other hand, broadcasters are responsible for publishing public blockchain transactions.
The EIP-7701 divides Ethereum transactions into phases, which natively allow third parties to walk and pay fees at the right stage. This means that there is no need for a relay to accept private transactions of users to be anonymous by a separate creature.
Focil, on the other hand, prevents the censorship of transactions, including privacy-preserving. The relevance is that it may be that unknown transactions are at the higher risk of the victim’s fall in censorship attempts.

Infrastructure changes are required
A short-term solution to meet the privacy limits of current remote call methods (RPC) systems used to contact the blockchain, as Baterin suggested, is the implementation of a reliable implementation environment (tee).
Tee is a safe place within a processor that ensures code and data loaded within it is protected. Buterin explained that “it allows users to interact with RPC nodes while gaining stronger assurance that their private data is not collected.”
As a long -term solution, tees should be replaced with a private information acquisition (PIR). PIR is a cryptographic protocol that allows users to obtain a specific item from a database without revealing which item is obtained.
This will allow users to obtain data about the contents of the blockchain without the provider knowing which data is shared. Blerin featured that it was best because it provides a “cryptographic guarantee.”
The Ethereum co-founder also argued that the wallets should be connected to many RPC servers. They should also use a separate RPC per DAPP and potential a mixnet-a privacy improvement technology designed to blur the metadata.
Other recommendations include the formation of proof-computing protocols for protocols that maintain privacy. This will result in significant lower fees for the use of such systems.
