Permissionless Systems

What changes when you stop asking for approval

3 min readOctober 27, 2021

Every time you check your bank balance, you're asking permission.

Not explicitly—you don't fill out a form or wait for approval. But somewhere in the process, a system controlled by an institution decides whether to show you your own money. That system can say no. It can freeze your account, delay your transfer, or simply go offline.

99.9% of the world operates this way. The other 0.1% uses permissionless systems.

Key Takeaways

  • Permissionless systems are networks where participation requires no approval—anyone can use them, build on them, or leave them at any time.
  • DeFi, NFTs, and DAOs are different manifestations of the same core idea: removing gatekeepers.
  • The capabilities are limited only by infrastructure and developer creativity, not by who's allowed to participate.

The Barter Baseline

Consider the simplest possible transaction: I have ten chickens, you have one cow. We both agree that's a fair trade. We exchange. Done.

No bank approved this. No payment processor took a cut. No government recorded it. Two parties agreed, exchanged, and walked away satisfied.

This is permissionless commerce in its purest form—peer-to-peer, no intermediaries.

Blockchains recreate this dynamic for digital assets. When you swap tokens on a decentralized exchange, there's no institution in the middle deciding whether to allow the transaction. The smart contract executes or it doesn't. The rules are the rules.

Three Manifestations

Most permissionless applications fall into three categories. They're not separate industries—they're different expressions of the same underlying capability.

DeFi: Finance Without Banks

Decentralized Finance is what happens when software developers and financial engineers build economic systems without asking banks for permission.

The goal: increase financial access while eliminating counterparty risk and barriers to entry.

The culture: open source. Anyone can read the code, fork it, improve it, or compete with it. This creates innovation velocity that traditional finance—with its closed systems and legacy infrastructure—can't match.

The result: lending markets, exchanges, derivatives, and yield instruments that run 24/7, globally, for anyone with a wallet.

NFTs: Ownership Without Registries

Non-fungible tokens are verifiably unique digital assets.

The concept is simpler than it sounds:

  • Fungible means interchangeable. One bitcoin equals one bitcoin. One dollar equals one dollar.
  • Non-fungible means unique. This specific token, with this specific history, owned by this specific address.

NFTs enable digital ownership without a central registry deciding who owns what. The blockchain is the registry, and it doesn't ask for permission to update.

Some NFTs are worthless. Some are worth millions. The market decides, not a gatekeeper.

DAOs: Coordination Without Hierarchy

Decentralized Autonomous Organizations are experiments in collective decision-making.

The premise: token holders can draft proposals, vote on them, and execute decisions through smart contracts—no CEO required.

The reality: messier than the theory. Most DAOs still have informal power structures. Voter apathy is real. Coordination is hard.

But the experiments continue. Some DAOs manage billions in treasury assets. Others pool funds for absurd goals—like KrauseDAO's attempt to buy an NBA team, which I was stupid enough to participate in.

DAOs may vote on treasury management, protocol upgrades, role assignments, or conflict resolution. The decisions are on-chain. The process is transparent. Whether that produces better outcomes than traditional governance is still being tested.

The Permission Problem

In traditional finance, your location determines your access.

US crypto traders can't access the same derivatives available internationally. Not because the technology doesn't exist—because regulators haven't provided clear guidance, so exchanges restrict access to avoid future liability.

This regulatory uncertainty creates jurisdictional arbitrage. Developers and capital flow to regions with favorable rules. The US loses economic activity not because it banned anything, but because it failed to clarify what's allowed.

This is a second-order effect of slow policy: talent doesn't wait for permission.

Trustlessness vs Trust

"Trustless" doesn't mean no trust exists—it means trust is placed in code and cryptography rather than institutions and people.

When you use a bank, you trust:

  • The bank won't freeze your account arbitrarily
  • The payment processor will settle correctly
  • The government won't seize your funds
  • The systems will stay online

When you use a permissionless system, you trust:

  • The smart contract code does what it claims
  • The blockchain will continue operating
  • Your private keys remain secure

Neither is trust-free. The question is what you're trusting, and whether that trust can be verified.

What This Enables

Permissionless systems don't replace everything. They create alternatives.

For most people in stable economies with functioning banks, traditional finance works fine. The permission layer is invisible because it rarely says no.

For people in unstable economies, under authoritarian governments, or simply outside the banking system—permissionless access isn't a philosophical preference. It's the only option.

The capabilities of these systems are bounded by infrastructure and creativity, not by approval processes. That's a different constraint than most of finance has ever operated under.

What gets built when anyone can build? We're still finding out.
