By combining the hardware security module with the communication module, the cooperation between Bluzelle and Equinix will significantly reduce obstacles, thereby avoiding the even distribution of potential proof-of-stake (PoS) node verification program opportunities.

Lower cloud hosting barriers change the validator landscape

The gradual transition to the Proof of Stake (PoS) consensus algorithm has solved some of the most pressing issues faced by larger blockchain adoption, such as scalability and energy consumption. Despite these huge advantages over more traditional proof-of-work (PoW) blockchains, improving accessibility has always been a major obstacle for predictable node validators.

For an industry that is committed to providing a level playing field for all stakeholders and participants, the cost of running a validator node is very high due to the ensuing hosting and security requirements. These costs involve running a robust and high-performance private infrastructure, which prevents most individuals from participating.

Therefore, only companies that have funds to fund private custody infrastructure and enterprise-level security agreements can participate in risk-taking, effectively denying access to small and medium-sized validators.

At the same time, even if the cloud hosting architecture is super accessible to ordinary people and can effectively match the private server infrastructure in terms of speed, performance and uptime, it turns out that protecting the information in the cloud network is a daunting task. Task.

With the latest hardware security module (HSM) solutions for cloud environments, the infrastructure constraints on the verifier node no longer prevail.

Migrating to a cloud hosting environment

One of the main reasons that the node verifier cannot run on the cloud infrastructure is that it may expose the security conditions of the verifier’s private key. The validator node must have high performance to maintain the reputation of the node. If a node is damaged for some reason and violates the mortgage agreement of the blockchain, it may reduce its reputation and cause a diagonal cut, which actually means that some or all of the coins pledged in the node are lost.

Since the security of the private key required to communicate with the network and verify the transaction block cannot be ensured, for small and medium-sized verifiers, cloud computing as a solution has been ignored. This is where the HSM appears, it is the answer to make the validator’s competitive environment fair.

Bluzelle, a distributed database solution, collaborated with digital infrastructure provider Equinix to introduce a solution that effectively enables verifiers to protect their private keys from cloud network attacks. By connecting Equinix’s Smartkey HSM with Bluzelle’s communication module, the exchange between the blockchain network and the verifier node can be uninterrupted without exposing the private key protected by the HSM.

Potential of all validators

The novel solution proposed by Bluzelle will reduce all obstacles in the operation process, because it greatly reduces the cost of running cloud-based nodes without compromising security. This effectively opens the door for anyone who wants to become a network verifier who uses ordinary computers.

The inclusion of an enterprise-level HSM means that verifiers do not have to build a private infrastructure, but can benefit from the affordable costs of using providers such as Amazon Web Services and Google Cloud. In addition, cloud hosting can provide the high speed and high performance required to maintain the credibility of validator nodes.

The new stakeout solution will only be applicable to Cosmos from the beginning. Nevertheless, Bluzelle still intends to expand compatibility with other blockchains including Ethereum in the future, so as to provide unprecedented benefits to community members who were left behind due to high infrastructure barriers.
