World Chain, a Layer‑2 blockchain linked to Tools for Humanity (founded by Sam Altman), has officially rolled out its Priority Blockspace for Humans (PBH) upgrade on mainnet. This highly anticipated “human‑first” protocol gives 13 million verified users preferential treatment over automated bots during block production .

What Is PBH and Why It Matters

The PBH system reserves a segment of each block specifically for transactions from Orb‑verified humans—allowing real users to bypass bot congestion and premium gas fees .

On congested networks, bots often dominate blockspace, making it expensive and slow for regular users. PBH reverses this dynamic by giving humans top priority—creating a more fair, efficient, and accessible blockchain experience .

Tested and Trusted

PBH was launched after extensive testing by leading blockchain firms like Flashbots and Alchemy, validating its effectiveness and robustness in both testnet and mainnet environments .

Open‑source by design, PBH enables developers and users to audit and improve the protocol—and helps ensure blockspace remains reliable for real human interactions .

A Paradigm Shift in Blockchain

This upgrade marks a major shift: moving from a purely economic “gas-first” model to a more human-centered architecture. World Chain’s approach sets a new standard, fostering an equitable blockchain that truly serves its verified users .

Final Take

With PBH live, World Chain reinforces its mission to build a human-first decentralized network, enabling smoother, cheaper, and fairer transactions for real people. As bots and MEV systems continue to dominate chains, this innovation offers a promising path toward a more inclusive, trustworthy Web3 future.
