Co -founder Ethereum Vitalik Buterin outlined a comprehensive plan to escalate the privacy of the network that he helped to create.
In the road map of April 11, Buterin argued for including privacy tools in Ether wallets (ETH) and implementation of standards and functions that escalate privacy in the ecosystem and Ethereum protocol. He explained that the road map is a compact -term solution that requires constrained changes in the basic protocol along with additional long -term updates.
Buterin recommends accepting systems that escalate privacy, such as railway pools or privacy pools, existing wallets, as planned. When the funds are sent with these portfolios, it claims that users should welcome the option “sending from a sheltered balance”, which anonymizes the transaction and should be “perfectly enabled”. He wrote:
“Users should not download a separate” privacy portfolio “.

Main changes recommended for DEFI
Buterin also recommended deep changes in how decentralized finances (DEFI) and wider decentralized applications (DAPP) are implemented. He claimed that these systems should be limited to “one address per application”.
The co -founder of Ethereum admitted that this would require “significant sacrifices of convenience”, but “this is the most practical way to remove public connections between all your activities in various applications.” He also emphasizes that the user’s sensations would be “very similar” to depositing funds into one chain from another in cross -country interoperability.
Barein also emphasized that in order to enjoy the benefits of this change, programmers would have to make sure that the functions of withdrawing users are default privacy.
Needed changes in the Ethereum protocol
Other changes included is implementation Turning lists for choosing a fork (bonfire) and Ethereum (EIP) 7701 improvements proposal. The latter is an improvement in the abstraction of the Ethereum account, and the former is an improvement in censorship resistance.

EIP-7701 ensures that privacy protocols can operate without the need for relays or public broadcasters. This, in turn, simplifies the development and maintenance of this type of protocol.
The relays in this context are intermediaries or nodes responsible for accepting and transferring transactions. On the other hand, sender are responsible for publishing transactions for public blockchain.
EIP-7701 divides Ethereum transactions into phases, natively allowing the third parties to enter and pay fees in the right phase. This means that there is no need to accept private user transactions to be an anonymous broadcast by a separate unit.
On the other hand, Focil prevents transaction censorship, including privacy. It is presumed that anonymized transactions are a much higher risk of the victim’s fall in the case of censorship prices.

Infrastructure changes are required
The short -term solution regarding the privacy of current remote connection systems (RPC) used to interact with blockchain, as proposed, is the implementation of a trusted execution environment (TEE).
TEE is a safe area in a processor that provides protected code and data inside. Barein explained that “this allows users to interact with RPC nodes, while obtaining a stronger assurance that their private data is not collected.”
As a long -term TEE solution, it should be replaced with a private information search system (PIR). PIR is a cryptographic protocol that allows users to recover a specific element from the database without disclosure which element has been recovered.
This would allow users to download data on blockchain content without sharing, which data is available. Barein emphasized that he is better because he provides “cryptographic guarantees.”
The co -founder of Ethereum also argued that wallets should be connected to many RPC servers. They should also use a separate RPC on DAPP and potentially mixnet-technology that improves privacy designed to darken metadata.
Other recommendations include the development of evidence aggregation reports regarding privacy protocols. This would cause much lower fees for using such systems.
