Permissionless

What does it mean to be ‘Permissionless’?

The most transformative systems in history, from open markets and free societies to the internet itself, are those that empower individuals to create, trade, speak, and innovate without needing the permission of an agreed upon authority. 

By eliminating gatekeepers, these systems foster environments where innovation can thrive without the need for approval.

At its core, permissionless means that anyone can participate without needing to meet someone else’s conditions. It stands in direct contrast to permissioned systems, where access is controlled by sovereigns, licenses, or curated membership. In a permissionless environment, opportunity is not given — it is seized and built upon by those willing to act.

The importance of permissionless-ness today is hard to overstate. It is the engine behind decentralized technologies like blockchain and Web3, where users no longer have to rely on banks to transfer money, corporations to store their data, or platforms to validate their identity. It promises a future where creativity, commerce, and community belong to everyone, rather than only the credentialed few.

Permissionless Origins

Permissionless innovations have been a catalyst for progress throughout history, long predating the internet and blockchain. This principle, which allows individuals to participate freely in systems without centralized control, has appeared time and again, from ancient trade routes to the digital age, quietly driving civilization forward.

In the earliest barter economies, trade flourished without intermediaries. Two individuals could exchange goods or services directly, relying only on mutual trust and need. No kings, banks, or bureaucracies dictated who could participate. These open markets laid the groundwork for decentralized commerce, even if their reach was limited by geography and the need for coincidence of wants. Still, the essence was there: the freedom to transact was permissionless.

Centuries later, a technological breakthrough shattered another gatekeeping system. When Johannes Gutenberg introduced the movable-type printing press in the 15th century, he removed the religious and political monopolies on information. Knowledge could now be widely disseminated and mass-produced, rather than laboriously copied by hand solely within monasteries.

No longer did scholars and writers need permission from the Church or royal courts to share ideas. The printing press sparked an information revolution, fueling the Reformation, the Renaissance, and the birth of modern science. It was, in many ways, an early form of permissionless communication.

Political systems, too, evolved toward more permissionless structures. Ancient Athens introduced a rudimentary form of direct democracy, where eligible citizens voted and debated public matters without needing aristocratic approval. Though far from inclusive by modern standards, the Athenian ecclesia demonstrated that collective governance could emerge outside rigid hierarchies. This gave humanity an early glimpse at open participation in public life.

The 20th century brought permissionless attitudes into the realm of technology and communication. The architects of the early internet wanted it to be open and decentralized. Protocols like TCP/IP allowed anyone to connect, create, and exchange information without needing approval from a central authority.

This permissionless innovation fueled the explosive growth of the web, from personal websites to startups like Google and Amazon; none of which could have found their footing if a telecom company or government agency had to grant explicit permission to build online.

Meanwhile, breakthroughs in cryptography fortified the ability to communicate securely without gatekeepers. In the 1970s, Whitfield Diffie and Martin Hellman introduced public-key cryptography, allowing two parties to establish secure communications without a trusted intermediary. Later, the 1990s “Crypto Wars” saw pioneers like Phil Zimmermann defend the right to strong encryption for the public.

Across every era, the pattern is clear: when individuals are freed from seeking permission to exchange, build, communicate, or govern, progress accelerates. Permissionless systems that open their doors (rather than policing access) unleash creativity, resilience, and innovation on scales that permissioned systems cannot match.

The problem with permission-based systems

Although permissionless systems have been responsible for some of the most significant advancements in history, the majority of human institutions were intentionally designed to be permissioned. A permissioned system restricts participation. Individuals must obtain approval, satisfy certain requirements, or depend on intermediaries to access essential services, opportunities, or spaces. While these barriers may be intended to promote order, safety, and fairness (as well as generate greater financial profits for those in control), they frequently result in exclusion, inefficiency, and centralized power.

Financial systems are among the clearest examples.

To open a bank account, individuals typically must provide government-issued identification, prove residency, and meet regulatory thresholds. Sending money across borders requires navigating a labyrinth of correspondent banks, compliance checks, and high fees. Those who lack the right documents, such as the poor, the marginalized, and the displaced, are often locked out entirely.

According to the World Bank, over 1.7 billion adults remain unbanked, unable to access even basic financial tools because permission is denied.

Technology platforms have replicated similar permissioned gatekeeping, sometimes called ‘walled gardens’. On Apple’s iOS ecosystem, developers must submit their apps for approval, comply with strict rules, and often pay significant fees for the privilege of distribution. Social media platforms moderate who may post, what content is acceptable, and even which users are allowed to exist on the platform at all.

While some regulation is necessary for quality and safety, these centralized permissions have also stifled innovation, entrenched monopolies, and given a handful of corporations enormous power over global communication.

Governments, too, have long relied on permissioned systems to regulate commerce and civil life. India’s mid-20th century Licence Raj offers a cautionary tale, wherein entrepreneurs needed approval from dozens of agencies to start even a simple business. Instead of fostering innovation, this web of permissions bred inefficiency, corruption, and stagnation. It wasn’t until the system was dismantled in the 1990s that India’s economy unlocked faster growth.

Even in cultural realms, permissioning has created bottlenecks. For decades, musicians needed record label contracts to reach an audience. Authors needed a publisher’s blessing to see their work in print. Scientists needed journal approval to circulate their discoveries. These gatekeepers provided the veneer of legitimacy but also created chokepoints. Likewise, they stifled new voices, favoring established players, and delaying the spread of ideas.

The core problem with permissioned systems is that they concentrate decision-making power. Those who control access inevitably shape who gets opportunities and who is excluded. In the best cases, permissioning creates standards that protect users. In the worst cases, it fosters inequality, monopoly, censorship, and rent-seeking behavior.

Permissioned environments tend to calcify over time. Rules pile atop rules, exceptions harden into norms, and the cost of gaining permission grows steeper. Innovation slows not because new ideas disappear, but because the friction involved in bringing them to life becomes unbearable.

Blockchain and the reinvention of permissionless values

Bitcoin’s emergence in 2009 revolutionized the concept of value transfer. It enabled secure, affordable, and instantaneous global transactions, eliminating the need for intermediaries like banks, governments, or other trusted third parties. Anyone with an internet connection could create a wallet, send transactions, and verify the ledger. No application process. No approval. No permission required.

It was the beginning of a new chapter: permissionless finance.

Satoshi Nakamoto’s Bitcoin whitepaper described a network where trust was minimized, consensus was public, and participation was open to all. This structure made Bitcoin permissionless by design: anyone could join the network as a user, a miner, or a node operator. The rules were enforced not by authorities, but by code — transparent, predictable, and available for all to audit.

Ethereum expanded this vision when it launched in 2015. Now, Satoshi’s innovation was no longer limited to sending and receiving money. Ethereum allowed anyone to write and deploy smart contracts, or self-executing programs that lived directly on the blockchain. These contracts could define financial agreements, build games, create distributed organizations, and more, all without seeking permission from a bank, a tech giant, venture capitalists, or governments.

The rise of decentralized finance (DeFi) illustrates the radical power of this mode especially well. Platforms like Uniswap, Aave, and MakerDAO created financial markets where anyone could lend, borrow, trade, or save without needing an account, a banker, or an invitation. 

Financial services that once required layers of permission now ran automatically, open to any user at any time.

Other real-world examples show how transformative this shift has been. An artist in Nairobi can mint and sell digital art as NFTs to collectors worldwide without a gallery’s approval. A farmer in rural Argentina can deposit savings into a DeFi lending pool and earn returns without opening a traditional bank account. A developer in Manila can launch a new token or build a decentralized application without asking an exchange or platform for listing rights.

Of course, permissionlessness brings challenges too. Without gatekeepers, scams, hacks, and failures happen more publicly. Without centralized control, disputes and upgrades require new forms of collective governance. Scalability remains a constant hurdle. Yet despite these difficulties, permissionless systems have continued to grow, precisely because they unlock freedoms that traditional systems cannot offer.

The future of being permissionless

As blockchain networks continue to mature, the permissionless principle is poised to expand far beyond finance and into every corner of digital and physical life. Already, we see the outlines of a world where identity, computation, governance, and creativity operate on open rails. This occurs not because someone granted access, but because the system itself refuses to deny it.

One of the most anticipated frontiers is decentralized identity. Today, online identity is fractured across a multitude of platforms, mostly controlled by corporations and governments. To access services, users often surrender personal data, placing their privacy and autonomy at risk. 

Permissionless identity systems, which are built using decentralized identifiers (DIDs) and verifiable credentials, promise a different model.

Individuals would own their digital identities directly. Each person would choose when and how to share information without relying on centralized issuers. Imagine proving your education, employment, or citizenship without needing a username, password, or approval from an intermediary. Identity becomes portable, composable, and sovereign. It would de-permission entrenched social gatekeepers, unlocking access to universal services without being stifled by imaginary borders and third-party parameters.

Another emerging horizon is the decentralization of artificial intelligence. Today’s AI breakthroughs are largely confined to massive tech companies with the resources to train colossal models. But open-source AI networks, meaning decentralized marketplaces where data, algorithms, and compute power are shared permissionlessly, are beginning to take shape. 

Projects like SingularityNET envision a world where anyone can contribute to, and benefit from, collective AI development. In this future, AI could be a public good rather than a proprietary weapon. It could be accessible, remixable, and decentralized by default.

The open metaverse represents yet another universal frontier. Instead of virtual worlds owned by single corporations with closed economies and controlled access, blockchain-based platforms aim to create interoperable spaces where users own their assets, identities, and experiences. Virtual land, avatars, and digital goods can move freely across different environments, and no single entity can revoke ownership.

In finance, permissionless systems are starting to bridge into the real economy. Tokenized real-world assets, from real estate to bonds, are finding their way onto decentralized platforms. As the technology matures and regulation adapts, we could see a world where property rights, investments, and even public infrastructure funding operate on permissionless rails.

Financial inclusion could extend to billions, bypassing many of the systemic barriers that have long excluded large swathes of the global population.

But permissionless ideals don’t just unlock technological innovation. They invite millions who have been sidelined by geography, bureaucracy, or circumstance to participate in building, trading, governing, and creating on a global stage. Permissionless systems shift the question from “Who allowed you to do this?” to “What can you imagine, and how will you make it real?”

Why Blockworks chose ‘Permissionless’ 

Blockworks chose to name its flagship developer event ‘Permissionless’ because it captured the deeper ethos that defines the future we believe in. A world where anyone can build, innovate, and participate without deferring to authority. A world where access isn’t granted — it’s assumed. Where possibility isn’t rationed — it’s limitless.

That belief shaped the creation of the Permissionless conference. Permissionless is a gathering not of elites, but of builders. From the beginning, our mission was simple: to create an open forum where the brightest minds in crypto and Web3 could meet face-to-face, share ideas, challenge norms, and imagine what comes next — all without barriers to entry.

It’s the physical embodiment of the same permissionless spirit that powers Bitcoin, Ethereum, DeFi, and the broader movement toward web3’s decentralized ecosphere.

Our inaugural Permissionless in 2022 captured that energy at a pivotal moment. Over 5,000 attendees — developers, investors, artists, creators — came together to celebrate the possibilities unlocked by open networks. It was a manifestation of a community that had grown up online, now stepping into the real world to shape its future together. Panels tackled DeFi’s evolution, NFT creativity, and the rise of DAOs. Conversations spilled from stages into hallways, onto beaches, and into late-night brainstorming sessions. It was permissionless both in spirit and in action.

Each year since, the conference has evolved alongside the industry it celebrates.

Permissionless II in 2023 dove into the tougher questions emerging from a maturing crypto space: How do we rebuild trust after setbacks? How do we scale without losing openness? How do we ensure that the decentralized future remains genuinely accessible to all? It was a forum for self-examination, for re-committing to the ideals that matter.

Permissionless III built on that momentum, further expanding into new frontiers like modular blockchains, AI integration, restaking, and decentralized identity. New voices joined the conversation, and through it all, the spirit of permissionless innovation remained the thread tying it together: anyone could come. Anyone could contribute. Anyone could help build the next chapter.

Now, as we look ahead to Permissionless IV, set for June 24–26, 2025 at Industry City in Brooklyn, NY, the movement continues to grow. Our next gathering will bring a new generation of builders, thinkers, and pioneers together in the heart of one of the world’s most iconic innovation hubs, all united by the same belief: that the future belongs to those who refuse to wait for permission.

For us, Permissionless is more than a conference name. It’s a guiding philosophy. It’s a recognition that the best ideas, the biggest breakthroughs, and the most meaningful communities emerge when people are free to create.

In a world still grappling with gatekeepers and barriers, we believe permissionless innovation is the future. And at Blockworks, we are proud to champion that future — one conversation, one collaboration, one conference at a time.
