Blockchain systems that typically produce lower average transaction fees are those that use Proof of Stake, variants such as Delegated Proof of Stake, permissioned models like Proof of Authority, and networks that enable extensive Layer-2 scaling. Evidence from protocol design and applied research shows that these approaches reduce per-transaction costs by raising throughput, shortening confirmation latency, and lowering resource consumption. Research by Aggelos Kiayias, University of Edinburgh, on the Ouroboros family of proof-of-stake protocols explains how staking and leader selection can secure a chain while avoiding the computational arms race of mining. Vitalik Buterin, Ethereum Foundation, has argued that moving from energy-intensive consensus to PoS plus sharding enables greater transaction capacity and lower fees when combined with off-chain techniques.
Consensus mechanisms that lower fees
Proof of Stake avoids the high energy and hardware costs intrinsic to Proof of Work, reducing the operational expenses that can be passed to users as fees. Delegated Proof of Stake shifts block production to trusted delegates, increasing block frequency and throughput in networks such as EOS and TRON, which can compress fee markets at the expense of increased centralization risk. Proof of Authority and other permissioned consensus protocols used by enterprises prioritize throughput and predictable costs, which often translates to negligible transaction fees in closed networks. Layer-2 designs such as the Lightning Network proposed by Joseph Poon and Thaddeus Dryja dramatically reduce on-chain fees by batching or routing transactions off-chain until settlement is required.
Causes and consequences
Lower fees arise from three technical causes: higher transaction processing capacity per unit of time, cheaper validator/operator overhead, and improved finality that reduces confirmation uncertainty. A 2014 study by Ittay Eyal, Cornell Tech, and Emin Gün Sirer, Cornell University, highlighted incentive pressures in Proof of Work that can exacerbate fee volatility during congestion, underscoring why alternative consensus models can stabilize costs. However, lower fees are not free: many low-fee designs increase risks of centralization, regulatory scrutiny, or reduced censorship-resistance. Culturally and territorially, permissioned and delegated systems appeal to businesses and jurisdictions prioritizing regulatory compliance and low transaction costs, while public PoS chains are often preferred in communities valuing decentralization and openness. Environmentally, the shift away from PoW reduces energy consumption and associated emissions, a consequence cited repeatedly by Ethereum Foundation research as a public-benefit consideration alongside cost reductions.
