Valid Blocks

Valid Blocks is a non-custodial proof-of-stake validator and staking infrastructure provider based in Romania. The company operates bare-metal servers in Tier 3+ data centers to run validator nodes on behalf of delegators, enabling token holders to earn staking rewards without transferring custody of their assets.

Founded in 2018 by two co-founders who participated in the Cosmos Game of Stakes competition, Valid Blocks has operated validators on Solana since the Tour de Sol 2 testnet in early 2020 and on MultiversX since its mainnet genesis in July 2020. The service also runs Subsquid (SQD) worker nodes on the decentralized data layer. Reported uptime across its infrastructure stands at 99.98%. The service targets individual delegators as well as institutional participants seeking reliable, transparent validator operations.

Valid Blocks provides a live performance dashboard and communicates operational status through Telegram and X (formerly Twitter). All staking arrangements are non-custodial, meaning delegators retain control of their private keys throughout the process.
