Bluzelle Leverages Equinix SmartKey® to Enable Secure Cloud-Hosted PoS Validators For the First Time
Decentralized database provider Bluzelle has collaborated with Equinix, the world’s digital infrastructure company, to allow hosting validators in Proof-of-Stake blockchains on standard cloud computing solutions.
- Problem: Currently professional validators have the tech expertise to run a node on a dedicated server. For Web3 to grow, we need millions of regular web users to be able to run a node that is just as secure as a professional.
- Solution: Bluzelle built a module with Equinix SmartKey on Google Cloud to sign blocks whenever requested by TMKMS. This separates the vital private key information from the computing environment on Google Cloud. It’s like having your Ledger Nano S store your private keys and the networks never being exposed to them.
- Why This Matters: It enables stakers, especially smaller ones, to set up a secure and high-performance validator on Google Cloud Platform. Though we are starting with Bluzelle and Cosmos based blockchains, we are also going to extend the solution over time to all the others, including Ethereum, Polkadot and more.
Utilizing the capabilities of Hardware Security Modules (HSM), secure chips designed to prevent any software or hardware-based form of tampering, and Bluzelle’s proprietary communication module, stakers are able to set up their validators on the traditionally insecure cloud environment.
Setting up validator nodes for PoS blockchains on cloud providers such as Google Cloud Platform or Amazon Web Services is a highly alluring proposition. The distributed and cost-effective cloud computing infrastructure allows to avoid many of the challenges traditionally involved with staking, including maintaining impeccable uptime and performance.
However, validating a Proof-of-Stake network requires the utmost degree of security, and hosting the node on the cloud would expose the validator’s private key to the cloud network. If the validator’s environment ...
