Vitalik Buterin explained that solo stakers are people who independently stake their cryptocurrencies, in particular, ether. Importantly, these users do not rely on third-party services, centralized organizations, or staking pools that may pose a risk to the long-term stability of the network and its sustainable operation. Solo stakers are an uncoordinated and diverse group that reduces dependence on centralized entities, Buterin emphasized.
“The more solo stakers there are, the more privacy and security Ethereum will have. Even a small percentage of solo stakers can increase the decentralization of the blockchain,” Buterin said.
As an example, Buterin cited so-called 51% attacks, where an attacker takes over a majority of the computing power of a blockchain. In scenarios where a 51% attack could threaten the network, the key difference is how much of the computing power the attacker controls: 50-56% or higher than 57%. In the second scenario, a malicious actor can finalize blocks, which can lead to a chain split — if left unchecked and uncontested.
To prevent such a negative scenario, Buterin proposed raising the block finality threshold from two-thirds to a higher value. This should make it more difficult to carry out attacks, Buterin believes. According to him, Ethereum needs to increase the quorum threshold from two-thirds to three-quarters, and maybe even higher.
Last week, the Ethereum co-founder urged users to be more critical of smart wallets to avoid exposing themselves to privacy risks. Buterin emphasized that not all wallet innovations empower users.
