Web3’s TCP/IP Moment: The Missing Puzzle Piece 🧩

Ah, the internet-that grand tapestry of human ingenuity, woven with threads of data and dreams. Yet, here we stand, gazing upon Web3, a child of promise, still stumbling in the shadows of its 1980s networking cradle. 🦖 While the original internet scaled on the wings of IP, a universal fabric that turned chaos into harmony, Web3 inherited a patchwork quilt of ad-hoc protocols. These relics of a bygone era choke its ambitions, unable to bear the weight of billions of AI agents, global settlements, or a planetary sensor mesh. Faster chains? Bigger blocks? Mere bandages on a gaping wound. 🩹

Web3, my dear reader, is a chariot pulled by snails. 🐌 It craves a universal, decentralized data protocol-its own TCP/IP-to achieve the trustless, global throughput it so desperately desires.
Mathematical marvels like RLNC whisper a truth: decentralized networks can rival their centralized brethren, but only if we rethink data movement from the ground up. 🧠
A universal coded data layer? Ah, now we’re speaking Tolstoy’s language! It would mend the fragmented chains, birth trillion-dollar DeFi, and breathe life into global DePIN networks and decentralized AI. 🌍✨

Web3, my friend, needs its TCP/IP moment-a protocol born of the same principles that made the internet unstoppable, yet forged to preserve the soul of blockchain: trustlessness, censorship resistance, and permissionless participation. But this time, it must scale. 🌪️

The Blunders of the Past, Repeated with Finesse

Before IP, computers were solitary islands, unable to converse across the digital seas. IP, that unsung hero, crafted a universal standard, turning isolation into connection. It became the backbone of the internet, alongside compute and storage. Yet, Web3, in its youthful arrogance, repeats the sins of its forebears. Each blockchain, a fiefdom unto itself, invents its own networking layer-gossip protocols, Turbine, Snow, Narwhal, mempools, DA sampling. A Babel of incompatibility! 🗣️🔥

Everyone chases speed, like lemmings off a cliff, with bigger blocks, more rollups, and parallelization. But they build upon broken foundations, my dear reader. If we are to scale Web3, we need a protocol that is fast, trustless, fault-tolerant, and-above all-modular. 🛠️

Two Decades at MIT: Unraveling Decentralization’s Gordian Knot

For over two decades, I, Muriel Médard, have toiled in the halls of MIT, grappling with a question as old as decentralization itself: Can decentralized systems move information as swiftly and reliably as their centralized counterparts? And can we prove it mathematically? 🧮

We married two estranged fields: network coding theory, the mathematician’s darling, and distributed algorithms, crowned by Nancy Lynch’s work on consensus and Byzantine fault tolerance. The result? A revelation! Decentralized systems can match centralized performance-but only if we redesign data movement from first principles. Enter Random Linear Network Coding (RLNC), the mathematically optimal method for this grand endeavor. 🌟

With blockchains, the application became clear: the internet we know was built for trusted intermediaries. The decentralized web demands its own protocol, one that withstands failure and attack while scaling globally. Its architecture is a symphony: performance from mathematics, not hardware; coordination from code, not servers; and a network that grows stronger as it decentralizes. 🎶

Performance? Mathematics, not brute force. 🧮
Coordination? Code, not servers. 🤖
Decentralization? Its strength, not its weakness. 🌐

Like the original IP, it does not replace but enables. A foundation for the unimaginable. 🌌

The Use Cases That Expose Today’s Frailties

Decentralized systems teeter on the brink, just as the world demands their ascent. Four macro trends lay bare the same bottleneck: Web3 still clings to networking assumptions inherited from centralized systems. 🌊

1. The Fragmentation of L1s and L2s: A Tower of Babel

A hundred blockchains, each a kingdom unto itself, scale locally but falter globally. Data movement is restricted, inefficient, sub-optimal. What they lack is an electric grid for data-a shared layer that routes bandwidth where needed. A decentralized Internet Protocol would offer every chain access to the same coded data fabric, accelerating block propagation, DA retrieval, and state access without touching consensus. Congestion? Minimized. 🛣️⚡

2. Tokenization & DeFi: Trillions on Shaky Ground

DeFi, that grand experiment, cannot settle trillions on networks where propagation is slow, and load collapses systems. A shared coded network would absorb and redistribute spikes, sparing any single chain from overwhelm. Traditional systems build larger data centers, expensive and fragile. Decentralized systems must rely on coded distribution. 🏗️💸

3. DePIN at Global Scale: A Symphony of Devices

A global network of millions of devices cannot function on slow, single-path communication. They must act as one, like a single organism. In energy systems, flexible grids absorb both mining operations and hair dryers. In networking, a decentralized protocol must do the same for data: absorb every source optimally and deliver it where needed. Coded storage, coded retrieval, and every available path-this is the future. 🔌🌍

4. Decentralized AI: Data Logistics, Not Storage

Distributed AI, training on encrypted fragments or coordinating AI agents, demands high-throughput, fault-tolerant data movement. Today’s decentralized storage and compute are separated, slow, and reliant on centralized gateways. AI needs data logistics: encoded data in motion, stored in fragments, retrieved from the fastest source, and recombined instantly. No single point of failure. 🤖🚀

Web3’s Next Leap: The Unimaginable Awaits

Every leap in the internet’s evolution began with a breakthrough in data movement. IP brought global connectivity. Broadband birthed Netflix and the cloud. 4G and 5G gave us Uber, TikTok, and real-time social. GPUs ignited deep learning. Smart contracts unlocked programmable finance. A universal, coded data layer would do for blockchains what IP did for the early internet: create the conditions for applications we cannot yet fathom. It transforms Web3 from experiment to inevitability. 🌠
