World Chain Debuts Human-First Blockchain Tool with Mainnet Launch of PBH

World, the blockchain initiative formerly known as Worldcoin, has officially launched “Priority Blockspace for Humans” (PBH) on the mainnet of its World Chain network. The innovation aims to strengthen the platform’s mission of building a decentralized system anchored in human identity, with 13 million verified users now benefiting from this rollout. PBH is an infrastructure layer that elevates transactions from verified individuals above others during periods of network congestion. Rather than relying on high gas fees to prioritize activity, PBH ensures a portion of every block is reserved exclusively for Orb-verified users—those who have authenticated their identity through World’s unique biometric verification system. This design guarantees timely access to essential network functions, such as identity verifications, decentralized applications (Mini Apps), and grant systems, without additional financial barriers. “Priority Blockspace for Humans effectively makes World Chain fairer and more efficient,” said Steven Smith, vice president of Engineering and Protocol at Tools for Humanity, one of World’s main contributors. “We believe this reflects a step forward in creating systems where humans and AI thrive together.” PBH has been extensively tested on an incentivized testnet, with input from teams like Flashbots and Alchemy. It’s fully open-source and integrates with Rollup Boost, a customizable tool built on OP Stack that allows for flexible transaction sequencing. Both components have undergone independent audits conducted by Nethermind. World Chain is a Layer-2 solution secured by Ethereum and designed for global accessibility. Tied to the Worldcoin protocol and powered by the World ID, it supports everyday use cases such as stablecoin payments and remittances, all accessible via supported wallets like World App.
