Bitcoin (BTC) has long been hailed as unbreakable and untouchable, a digital stronghold against the forces of change. Bitcoin’s bedrock of security is facing its first true test with quantum computing, which should be addressed sooner rather than later. Its cryptographic armor will crack if not addressed, forcing the network to adapt or perish.
Bitcoin’s node count is growing, but incentives are still absent
Bitcoin’s full node network has grown over time, a sign of increasing adoption and a more robust infrastructure, but the core issue remains. The voluntary act of running a node still has no financial incentive. Miners earn rewards for securing the network, yet full node operators get nothing for their role in keeping Bitcoin decentralized.
At the same time, a significant portion of these nodes are run by exchanges, custodians and large mining pools. These are centralized entities with financial incentives to maintain control. Suppose Bitcoin’s node network continues to expand without proper incentives. In that case, the risk remains that validation will become increasingly dependent on a few well-funded players rather than a truly distributed base of individual users (see Figure 1).
