TLDR
- David Schwartz stated that XRPL consensus was never built on XRP staking or validator rewards.
- He explained that XRPL relies on shareholder choice and trusted validator selection to maintain consensus.
- Schwartz said users coordinate through software implementations and community validator lists.
- He described mining and proof-of-stake validators as “artificial stakeholders” driven by profit motives.
- Schwartz argued that financial incentives can increase centralization in blockchain networks.
- He contrasted artificial stakeholders with “natural stakeholders” who depend on the network for payments and liquidity.
Ripple’s former CTO David Schwartz said the XRP Ledger (XRPL) consensus model never relied on XRP staking or validator rewards. He stated that the network depends on “shareholder choice” to maintain agreement and stop double-spending. His remarks followed the resurfacing of a six-year-old presentation titled “The Best Incentive is No Incentive,” where he outlined the design approach.
XRPL, XRP Staking, and the Consensus Structure
Schwartz explained that XRPL does not require users to lock up tokens for validation. Instead, users choose trusted validators and software implementations to reach consensus. He said this process works through community-selected validator lists and trusted groups. As a result, the system avoids direct financial rewards for block production.
He responded to questions on X about “stakeholder-chosen scarcity” and clarified the term. He said XRP itself is not staked to secure the network. Rather, users voluntarily agree on validators to order transactions. He added that this coordination happens “invisibly” through software choices.
Schwartz stressed that the network does not reward validators with new XRP. Therefore, validators focus only on confirming transaction order. He said this structure reduces profit-driven behavior. He maintained that XRPL relies on trust-based coordination instead of financial incentives.
Incentives, Validators, and Network Design
In his Stanford presentation, Schwartz argued that artificial incentives can distort blockchain systems. He described Bitcoin miners and proof-of-stake validators as “artificial stakeholders.” He said these participants often aim to maximize returns rather than protect the network.
He claimed that mining and staking rewards can push participants toward centralization. According to him, operators compete to lower costs and increase scale. Consequently, larger players can gain influence over time. He said this dynamic may weaken decentralization.
Schwartz contrasted this with what he called “natural stakeholders.” He defined them as users who depend on the network for payments and liquidity. He said these users share a common interest in maintaining speed and low costs. Therefore, they support stability without direct rewards.
He also stated that XRPL reduces validator power by design. The network avoids mining competition and block reorganizations. Validators only agree on transaction order using fixed rules. He said this structure limits opportunities for censorship or manipulation.
XRPL continues to operate without mining or staking rewards. Instead, it uses trusted validator coordination and community governance. Schwartz reiterated that the system was built around “just shareholder choice” rather than XRP staking.
