Hardware Vendor Lock-in

Hardware vendor lock-in occurs when a network becomes overly dependent on specific hardware components, such as specialized chips or servers, from a single manufacturer. This creates a supply chain vulnerability where the manufacturer could potentially restrict access or introduce backdoors.

For blockchain networks, this is particularly relevant for proof-of-work mining or high-performance validator hardware. Diversifying the hardware ecosystem is essential for maintaining the independence and security of the network.

If a protocol is tied to one vendor, it loses the ability to innovate independently or switch to more efficient alternatives. This is a strategic risk that must be managed by the community.
