  We present a novel method for a multi-party, zero-trust validator
infrastructure deployment arrangement via smart contracts to secure
Proof-of-Stake (PoS) blockchains. The proposed arrangement architecture employs
a combination of non-fungible tokens (NFTs), a treasury contract, and validator
smart contract wallets to facilitate trustless participation in staking
mechanisms. The NFT minting process allows depositors to exchange their capital
for an NFT representing their stake in a validator, while the treasury contract
manages the registry of NFT holders and handles rewards distribution. Validator
smart contract wallets are employed to create a trustless connection between
the validator operator and the treasury, enabling autonomous staking and
unstaking processes based on predefined conditions. In addition, the proposed
system incorporates protection mechanisms for depositors, such as triggered
exits in case of non-payment of rewards and a penalty payout from the validator
operator. The arrangement benefits from the extensibility and interoperability
of web3 technologies, with potential applications in the broader digital
ecosystem. This zero-trust staking mechanism aims to serve users who desire
increased privacy, trust, and flexibility in managing their digital wealth,
while promoting greater decentralization and transparency in the PoS ecosystem.
