MEV Explained: Maximal Extractable Value, Flashbots, MEV-Boost, PBS, Intents, and Ethereum Blockspace Markets

What is MEV?

MEV stands for Maximal Extractable Value. It refers to value that can be extracted by controlling or influencing the inclusion, exclusion, or ordering of transactions in a block. The older phrase was Miner Extractable Value because proof-of-work miners were the block producers. After Ethereum moved to proof-of-stake, the broader term Maximal Extractable Value became more accurate because the extraction path can involve validators, builders, searchers, relays, sequencers, private orderflow providers, and cross-domain solvers.

MEV exists because blockchains execute transactions in an order. If one swap happens before another, prices change. If a liquidation happens before a borrower repays, collateral moves. If a bridge message is finalized before a competing route, arbitrage appears. If an NFT mint is ordered earlier, one buyer wins. The chain is deterministic once the block is chosen, but the path into that block is an economic battlefield.

A simple example is DEX arbitrage. Suppose ETH trades at one price on one decentralized exchange and a slightly different price on another. A searcher can buy on the cheaper venue and sell on the more expensive venue in the same block. That profit is MEV because it depends on execution ordering. It may also help the market by aligning prices.

A harmful example is sandwiching. A user submits a swap with too much slippage. A searcher sees the pending transaction in the public mempool, buys before the user, lets the user move the price, then sells after the user. The attacker captures value from the user’s worse execution. The user pays more or receives less. That is toxic MEV.

MEV is not only about Ethereum

Ethereum is the most studied MEV environment, but MEV exists anywhere transaction ordering matters: Solana, rollups, appchains, bridges, DEX aggregators, perpetual exchanges, NFT marketplaces, lending systems, oracle networks, and cross-chain routers. The same basic idea appears wherever market state changes in discrete steps.

MEV is not always theft

Some MEV is necessary market maintenance. Arbitrage keeps prices aligned. Liquidations protect lenders from bad debt. Oracle updates can synchronize markets. The problem is not that value exists. The problem is when extraction becomes predatory, opaque, centralizing, or censorship-heavy.

MEV is a design problem

Wallets can route transactions privately. DEXs can use batch auctions, RFQ, or solver competition. L2s can decentralize sequencing. Validators can use builder markets. Protocols can rebate value to users. Ethereum can research PBS and inclusion lists. MEV is managed through system design, not slogans.

Where MEV comes from

MEV comes from the gap between visible intent and final execution. When a user signs a transaction, they often reveal information before the transaction is finalized. That information can be used by searchers, builders, bots, and orderflow providers. MEV also comes from price differences, delayed state updates, liquidation incentives, bridge timing, and market fragmentation.

DEX arbitrage

DEX arbitrage is one of the most common MEV categories. AMMs update prices only when trades execute. If two pools drift apart, a searcher can trade between them until prices realign. This can be useful because it improves market efficiency. The risk is that competition for the arbitrage can create gas wars, failed transactions, and builder concentration.

Back-running

Back-running happens when a searcher places a transaction immediately after a target transaction. If a large swap changes a pool price, a back-run can arbitrage the new state against another venue. Back-running can be less harmful than sandwiching because it does not necessarily worsen the user’s execution. Still, it can redirect value away from users and protocols if not designed carefully.

Liquidations

Lending protocols often reward liquidators for closing unhealthy positions. This is necessary because the protocol needs collateral to remain sufficient. MEV appears because the first liquidator to execute a profitable liquidation receives the reward. Searchers compete by simulating oracle updates, borrower health, gas costs, and bundle placement.

Sandwich attacks

Sandwiching is a toxic form of MEV. The attacker places a transaction before and after the victim’s swap. The first transaction moves the price against the victim. The victim executes at a worse price. The second transaction closes the attacker’s position for profit. This extraction is especially common when users set high slippage, trade through public mempools, or use weak routing.

NFT and mint MEV

NFT mints, rare listings, mispriced items, and whitelist windows create ordering value. Bots can race to buy underpriced assets, sweep floors, or prioritize mint transactions. Privacy and fair sequencing matter because mempool visibility can give faster actors an advantage over ordinary users.

Oracle and liquidation timing

Oracle updates can create MEV when they change asset prices used by lending or derivatives protocols. A searcher who sees or predicts a price update can race to liquidate positions, arbitrage perps, or reposition collateral. Protocols need robust oracle design, price bounds, and liquidation controls to reduce harmful timing games.

Cross-domain MEV

Cross-domain MEV spans multiple execution domains: Ethereum L1, rollups, appchains, bridges, shared sequencers, and off-chain venues. If a price moves on one rollup but not another, a solver with visibility across both can capture the spread. As rollups multiply, cross-domain MEV becomes more important.

The post-Merge block supply chain

Before Ethereum moved to proof-of-stake, miners produced blocks. After the Merge, validators propose and attest to blocks. But most validators do not build highly optimized blocks themselves. Instead, the ecosystem developed a modular block production supply chain where specialized actors compete to build blocks and bid for proposer inclusion.

The modern supply chain often has four roles: searchers, builders, relays, and proposers. Searchers look for profitable transaction bundles. Builders combine bundles and ordinary transactions into complete blocks. Relays connect builders with validators and help prevent theft or invalid bids in the out-of-protocol market. Proposers are validators selected to sign and publish blocks.

Searchers

Searchers monitor public mempools, private orderflow, DEX pools, lending markets, oracle updates, NFT listings, bridges, and rollups. They simulate strategies such as arbitrage, liquidation, back-running, and cross-domain execution. A searcher’s advantage comes from data, speed, modeling, capital, gas strategy, and builder relationships.

Builders

Builders assemble full candidate blocks. They evaluate searcher bundles, public transactions, private transactions, gas fees, refunds, orderflow agreements, and block validity. They bid to proposers for the right to have their block signed. Builder competition can increase validator revenue, but builder concentration creates centralization and censorship concerns.

Relays

Relays sit between builders and proposers in the current out-of-protocol builder market. They check block validity, hide the full block body from the proposer until signing, and help ensure the proposer receives the promised payment. Relays reduce certain theft risks, but they become trusted middleware and potential choke points.

Proposers

Proposers are validators selected to propose a block for a slot. In the MEV-Boost model, the proposer typically chooses the highest valid bid from relays and signs the corresponding header. The validator does not need to personally search for every MEV opportunity, which lets smaller validators access block-building revenue without running advanced search infrastructure.

Flashbots and MEV-Boost

Flashbots became central to the MEV conversation because it tried to make MEV extraction more transparent, reduce harmful externalities, and create better infrastructure around private orderflow and builder markets. Before Ethereum’s proof-of-stake transition, Flashbots helped route bundles to miners. After the Merge, MEV-Boost became the main out-of-protocol route for validators to access builder bids.

MEV-Boost is middleware that validators can run alongside their consensus and execution clients. It connects validators to relays, which aggregate bids from builders. The validator can choose the highest valid bid without personally building the block. This made block-building competition more accessible to validators, but it also made relay health and builder diversity important.

Why MEV-Boost exists

Without a builder marketplace, sophisticated validators or staking pools could capture more MEV than smaller validators. That would create economies of scale and centralization pressure. MEV-Boost reduces that gap by letting validators outsource block construction to specialized builders and receive bids in a competitive market.

What MEV-Boost improves

MEV-Boost improves access to builder competition, increases validator revenue opportunities, makes block-building markets more visible, and reduces the need for every validator to run advanced search infrastructure. It also helped Ethereum transition into a more modular post-Merge supply chain.

What MEV-Boost does not solve

MEV-Boost does not eliminate MEV. It does not fully solve censorship. It does not fully remove trust from relays. It does not prevent builder concentration. It does not automatically protect users from sandwiches. It is an important step, not the final design.

Relay dependency

Relays are useful because they reduce theft and invalid block risks in the current out-of-protocol market. But relying on relays creates a middleware dependency. Relay downtime, filtering policies, operational failures, or concentration can affect block production. That is why Ethereum researchers continue working on protocol-level PBS and inclusion mechanisms.

PBS and ePBS: separating block builders from proposers

Proposer-Builder Separation, or PBS, is the idea that the actor building a block should be separate from the validator proposing it. The builder specializes in block construction, simulation, bundle selection, and MEV optimization. The proposer specializes in consensus. This reduces the burden on validators and can make MEV access more equal across large and small validators.

Today’s MEV-Boost is an out-of-protocol PBS-like design. It relies on relays to make the market work. Enshrined PBS, often called ePBS, aims to bring essential parts of the builder-proposer market into Ethereum’s protocol. The goal is to reduce trusted relay dependence, make payment enforcement more robust, and improve censorship resistance.

Why PBS helps

If validators had to build blocks themselves, sophisticated operators would have an advantage. They could hire MEV teams, run advanced infrastructure, source private orderflow, and outcompete smaller validators. PBS lets validators sell blockspace to builders instead of becoming professional searchers.

Why ePBS matters

MEV-Boost works outside the core protocol. That means relays enforce important parts of the flow. ePBS would move more of the commitment, payment, and delivery logic into protocol rules. This can reduce relay trust and make the system more neutral.

Payment enforcement

Builders bid for proposer inclusion. The proposer wants assurance that the bid will be paid. The builder wants assurance that the proposer cannot steal the block body and avoid payment. PBS designs use commitment and reveal logic to reduce this trust problem. ePBS aims to make these guarantees stronger.

Censorship resistance

PBS alone does not solve censorship. A builder can still ignore certain transactions. Inclusion lists give proposers a tool to force known transactions into blocks. If builders fail to include required transactions, the block can be rejected or adjusted depending on the final protocol design.

Inclusion lists, censorship resistance, and neutral infrastructure

Censorship resistance is one of Ethereum’s most important values. MEV infrastructure can threaten it when builders, relays, private orderflow providers, or validators exclude transactions for political, legal, commercial, or strategic reasons. A market with many builders can help, but protocol-level tools may still be needed.

What inclusion lists do

An inclusion list lets a proposer identify transactions it has seen and require them to be included. This gives the proposer a censorship-resistance role even when a separate builder constructs the block. If a builder ignores transactions that should be included, the protocol can enforce consequences through block validity rules or rejection logic.

CRLists

Censorship-resistance lists, often discussed as CRLists, aim to ensure that builders cannot indefinitely ignore valid transactions. The exact design remains an active research area because inclusion rules must balance censorship resistance, block validity, DoS resistance, proposer incentives, and builder flexibility.

Encrypted mempools

Encrypted mempools hide transaction details until after ordering. This can reduce frontrunning and selective censorship because builders cannot easily see the contents before committing to inclusion. The challenge is implementation complexity, denial-of-service protection, liveness, and fair reveal timing.

Application-level compliance versus protocol neutrality

Some applications may need to comply with jurisdiction-specific rules. That does not mean the base protocol should become a discretionary filtering engine. The cleaner design is protocol neutrality with application-level compliance where required.

Private routing, order-flow auctions, and intents

Many user losses happen because transactions are visible before execution. A public swap with high slippage tells the market exactly what the user is about to do. Searchers can simulate the swap, find the sandwich path, and compete to place the attack in the same block. Private routing, order-flow auctions, and intents try to change this flow.

Private routing

Private routing sends transactions away from the public mempool. The goal is to prevent searchers from seeing and attacking the transaction before it lands. This can reduce sandwich risk for swaps and high-value actions. But private routing shifts trust to the routing provider. If that provider fails, censors, delays, or leaks orderflow, users face different risks.

Order-flow auctions

Order-flow auctions turn user orderflow into a competitive market. Instead of letting a searcher extract value from a user for free, the wallet or application can auction execution rights and route part of the value back to the user, protocol, validator, or public-goods fund. This makes value capture more transparent.

Intents

An intent describes what the user wants, not exactly how to execute it. For example, a user might say: swap this token for at least this output by this deadline, bridge to this chain, then deposit into this vault. Solvers compete to satisfy that goal. If designed well, the user gets better execution because solvers compete on price, reliability, and settlement.

RFQ and solver systems

Request-for-quote systems let market makers provide signed quotes that settle on-chain. Solver systems go further by competing to satisfy broader user goals. Both can reduce public mempool exposure and limit sandwich risk. But they create new concerns around solver concentration, quote fairness, routing transparency, and failure handling.

MEV refunds

Some systems return part of extracted value to users. Refunds can improve user outcomes, but they must be easy to verify. Users should know whether a route protected them, whether a rebate was paid, and whether a better route existed.

MEV on Layer 2s and rollups

MEV does not disappear on rollups. It changes shape. Many rollups currently use centralized or semi-centralized sequencers. The sequencer decides transaction order, provides fast confirmations, batches transactions, and posts data or proofs to Ethereum. That makes the sequencer a major MEV actor.

L2 MEV may come from DEX arbitrage, liquidations, NFT mints, oracle updates, rollup-specific DeFi, preconfirmation markets, bridge finality, and delayed L1 settlement. Because rollups are connected through bridges and shared liquidity, MEV increasingly spans multiple domains.

Centralized sequencer risk

A centralized sequencer can provide good UX, but it can also control ordering, censor transactions, capture MEV, or privilege private orderflow. Some rollups may route MEV back to the protocol or users. Others may keep it as sequencer revenue. The policy should be visible.

Shared sequencers

Shared sequencers coordinate ordering across multiple rollups. This can reduce fragmentation and enable cross-rollup atomicity. It can also create a new shared infrastructure layer that must be neutral, resilient, and censorship-resistant.

Based sequencing

Based sequencing lets Ethereum L1 proposers participate directly in rollup sequencing. This can improve alignment with Ethereum, but it introduces new timing, MEV, and UX considerations. Rollups must decide whether they prefer centralized speed, shared sequencing, based sequencing, or hybrid models.

Cross-rollup arbitrage

If the same asset trades at different prices on different rollups, solvers can capture spreads. Cross-rollup arbitrage can improve price alignment, but it gives an advantage to actors with fast bridging, good data, private orderflow, and low-latency infrastructure.

Bridge timing

Bridges create MEV because finality and message timing differ across chains. A solver who understands when a bridge message will settle can trade ahead of other users. This is why bridge design and MEV design are connected.

MEV mitigation designs

MEV mitigation works best as a stack. No single design solves every MEV category. A wallet may use private routing, but a DEX still needs slippage controls. A rollup may use shared sequencing, but bridges still need safe finality rules. A protocol may use batch auctions, but liquidations still need careful incentives.

Slippage controls

Slippage is the maximum price movement a user is willing to accept. Too much slippage invites sandwiches. Too little slippage causes failed transactions. Wallets and DEXs should provide dynamic, context-aware slippage settings, warn users about dangerous values, and avoid default settings that expose users to unnecessary extraction.

Deadline hygiene

Swap deadlines prevent transactions from executing long after market conditions changed. Long deadlines can create risk if a transaction remains valid in the mempool while price moves. Wallets should use reasonable deadlines and warn when a deadline is abnormal.

Batch auctions

Batch auctions clear many trades together according to a common rule. By reducing the advantage of being first within a batch, they can reduce certain ordering games. The tradeoff is latency and complexity.

RFQ and signed quotes

RFQ systems give users a signed quote from a market maker. The user gets a defined output if the quote remains valid. This can reduce sandwich exposure because the execution is not an open-ended pool trade. The tradeoff is dependence on quote providers and possible hidden spreads.

On-chain guardrails

Protocols can add checks against harmful execution patterns. Examples include price bounds, oracle sanity checks, dynamic fees, anti-sandwich logic, circuit breakers, TWAP controls, and delayed settlement. These must be designed carefully because attackers can route around simplistic protections.

MEV smoothing

MEV smoothing distributes MEV revenue across validators, sequencers, users, or protocol participants rather than letting one actor capture all of it. This can reduce winner-take-all incentives, but it requires transparent accounting and strong enforcement.

Wallet and dApp playbook

Wallets and dApps sit closest to users. They control defaults, routing, warnings, slippage, quote display, transaction previews, and post-trade analytics. That makes them one of the strongest defenses against toxic MEV.

Use protected routing by default for risky actions

Swaps, large transactions, NFT mints, liquidations, and high-value DeFi interactions should avoid unnecessary public mempool exposure. Protected routing can help, but the interface should explain that private routing may have liveness or provider risks.

Warn on unsafe slippage

Users often increase slippage when a transaction fails. Attackers exploit this. Wallets should warn when slippage is unusually high for the trade size, pair liquidity, market volatility, or route.

Show expected output and worst-case output

A user should see the expected output, minimum output, route, price impact, and whether the transaction is protected from public mempool visibility. If the route includes private orderflow or solver competition, that should be visible in plain language.

Use intent-style execution where possible

For complex tasks, the user should specify the goal and constraints. The app can let solvers compete for execution. This reduces the need for users to manually choose brittle paths that reveal exploitable information.

Display post-trade analytics

After the transaction, show whether the route avoided sandwiching, whether a refund was paid, whether execution matched the quote, and whether the user saved value compared with a public route. This builds trust and makes protection measurable.

Builder, relay, validator, and infrastructure playbook

MEV infrastructure operators carry serious responsibility. Builders, relays, validators, RPC providers, searchers, sequencers, and node operators influence whether blockspace remains competitive and neutral. Bad infrastructure design can centralize Ethereum even when the consensus layer remains decentralized.

Builder strategy

Builders need fast simulation, reliable mempool access, bundle handling, private orderflow integration, valid block construction, and competitive bidding. But performance should not come at the cost of opaque censorship or unfair market access. Builders should publish policies, support inclusion mechanisms, and avoid exclusive arrangements that entrench market power.

Relay strategy

Relays must be reliable, neutral, transparent, and resilient. Relay concentration is dangerous because relay policies can influence what reaches proposers. Validators should diversify relay configurations where possible and monitor relay health.

Validator strategy

Validators should understand which relays they use, how bids are selected, what fallback behavior exists, and how censorship risk is monitored. Running default infrastructure without understanding policies can unintentionally support centralization.

RPC and data infrastructure

MEV monitoring, transaction simulation, bundle testing, liquidation defense, and bridge observation depend on reliable RPC and archive access. Developers building dashboards, search systems, or risk monitors need stable node infrastructure. For Ethereum RPC, archive access, and production-grade Web3 data workflows, builders can use Chainstack as part of their infrastructure stack.

Resilience and fallback paths

Builders, relays, validators, and dApps should assume outages happen. Fallback relays, fallback RPC, local block building, monitoring alerts, status pages, and incident runbooks help reduce failure impact.

SUAVE, BuilderNet, and cross-domain orderflow

As Ethereum becomes more rollup-heavy, MEV becomes cross-domain by default. Users will swap on one rollup, bridge through another, settle on Ethereum, execute intents across chains, and use solvers that route through multiple liquidity venues. The actor who can coordinate across these domains may capture more value than actors limited to one chain.

SUAVE-style coordination

SUAVE is a Flashbots research and development direction for a privacy-first, MEV-aware, cross-domain orderflow and auction environment. The goal is to let applications, wallets, solvers, and builders coordinate orderflow across domains while reducing the centralization pressure that MEV creates on each individual chain.

BuilderNet direction

BuilderNet reflects the push toward more decentralized, neutral, and collaborative block building. The larger goal is to reduce reliance on a single centralized builder and make Ethereum’s block-building market more resilient.

Cross-domain MEV

Cross-domain MEV appears when value depends on state across multiple chains or rollups. Examples include rollup-to-rollup arbitrage, bridge latency opportunities, cross-chain liquidations, multi-chain intents, and shared liquidity routing. This MEV is harder to manage because no single domain sees the entire state at the same time.

Shared sequencing

Shared sequencers can coordinate ordering across multiple rollups. They can support fairer ordering, cross-rollup atomicity, and MEV sharing. But they also become critical infrastructure that must avoid capture and censorship.

Intent routers

Intent routers let users specify outcomes across domains. Solvers compete to execute. This can improve UX and reduce toxic MEV, but only if solver competition is healthy and execution guarantees are understandable.

Policy, compliance, and censorship pressure

MEV infrastructure is not politically neutral by accident. Relays, builders, RPC providers, wallets, sequencers, and orderflow routers may face legal, commercial, and operational pressures. When one layer becomes too concentrated, its policies can shape what users can do.

Policy transparency

Infrastructure providers should publish clear inclusion, exclusion, and ranking policies. Users and validators need to know whether a relay filters transactions, whether a builder uses private orderflow, whether an RPC provider blocks endpoints, and whether a sequencer has emergency powers.

User choice

A healthy ecosystem lets users and validators choose providers. Wallets should avoid locking users into one route. Validators should understand relay diversity. Rollups should provide clear fallback paths.

Protocol-level neutrality

The base protocol should minimize discretionary filtering. Application-level compliance can exist where legally necessary, but Ethereum’s core infrastructure should preserve permissionless access as much as possible.

Auditability

MEV systems should publish data that lets researchers track builder concentration, relay share, censorship patterns, private orderflow share, sandwich activity, refund behavior, and inclusion delays. Without transparency, the market becomes impossible to evaluate.

TokenToolHub workflow for MEV research

TokenToolHub readers can use MEV research to evaluate whether a transaction, dApp, rollup, bridge, or protocol exposes users to unnecessary ordering risk. MEV is not only a validator topic. It directly affects swaps, liquidations, bridge routes, NFT mints, airdrop claims, token launches, and DeFi interactions.

For users

Avoid reckless slippage. Use wallets or dApps that explain routing. Be careful with large swaps in thin liquidity. Avoid public mempool exposure for sensitive trades where protected routing is available. Review bridge timing before moving assets across domains.

For token researchers

MEV can make token launches more dangerous. Thin liquidity, public mint timing, weak slippage defaults, and unrestricted launch pools invite bots. Use the TokenToolHub Token Safety Checker as an early contract review step, then examine liquidity, launch timing, routing, and bot exposure separately.

For bridge researchers

Bridge MEV depends on finality, message delay, liquidity depth, route selection, and cross-chain price movement. Use the TokenToolHub Bridge Helper to structure route research, then ask whether the bridge has timing or sequencing assumptions that solvers can exploit.

For builders

Use TokenToolHub Advanced Guides to study adjacent topics such as rollups, data availability, formal verification, bridge risk, intent systems, smart contract security, and governance. MEV-aware design should be part of the architecture, not an afterthought.

Common mistakes when discussing MEV

The first mistake is saying MEV can be fully eliminated. As long as ordering changes payoffs, MEV exists. The practical goal is to reduce harmful MEV and distribute unavoidable MEV more fairly.

The second mistake is treating all MEV as theft. Arbitrage and liquidations can support healthy markets. Sandwiching and censorship are different. A serious policy separates useful, neutral, and toxic MEV.

The third mistake is assuming private routing is always safer. Private routing can reduce sandwich risk, but it introduces trust and liveness tradeoffs. Users should know who receives the transaction and what happens if the provider fails.

The fourth mistake is ignoring builder concentration. MEV-Boost improved validator access to block-building revenue, but builders and relays still need diversity and transparency.

The fifth mistake is ignoring L2 MEV. Rollups have sequencers. Sequencers order transactions. Ordering creates value. L2 MEV is already part of the scaling stack.

The sixth mistake is focusing only on protocol research while ignoring user defaults. Most sandwich losses are made worse by weak wallet UX, unsafe slippage defaults, and public mempool exposure.

The seventh mistake is treating cross-domain MEV as future-only. As users move across rollups and bridges today, solvers already compete over multi-domain execution.

Glossary

Final verdict: MEV is the hidden market behind transaction ordering

MEV is one of the most important forces in Ethereum and modular blockchain design because it exposes a simple truth: transaction ordering has value. That value can support healthy markets through arbitrage and liquidations, or it can harm users through sandwiches, frontrunning, censorship, and opaque orderflow capture.

Ethereum’s post-Merge MEV stack professionalized the block production market. Searchers find opportunities. Builders assemble blocks. Relays connect builders to validators. Proposers sign blocks. MEV-Boost gave validators access to builder competition, but it also created new questions around relay trust, builder concentration, censorship, and market transparency.

PBS and ePBS are the protocol-level response. By separating block building from block proposing, Ethereum reduces the pressure for every validator to become an MEV expert. By researching inclusion lists, payment enforcement, and censorship-resistant block construction, Ethereum moves toward a more neutral infrastructure layer.

At the user level, the strongest protections are practical: better slippage defaults, private routing, RFQ, batch auctions, solver competition, intents, post-trade analytics, and clear route disclosure. Users should not need to understand every builder and relay to avoid being sandwiched.

At the rollup level, MEV becomes a sequencing problem. Centralized sequencers, shared sequencers, based sequencing, cross-rollup arbitrage, bridge latency, and preconfirmations all create new ordering markets. As Web3 becomes modular, MEV becomes cross-domain. The future belongs to systems that coordinate execution fairly across chains without letting private monopolies control orderflow.

The practical conclusion is direct. MEV is not only a validator topic. It affects every swap, bridge, liquidation, NFT mint, rollup transaction, and intent route. The best systems will not pretend MEV is gone. They will make it visible, reduce toxic extraction, protect users by default, diversify infrastructure, and route more unavoidable value back to the people and protocols that create it.
