Together, they serve as Co-CEOs of NextBlock

NextBlock is a US-based new media company reimagining digital ads for a decentralized future. Our founders, software and strategy experts, were hobbyist podcasters struggling to promote their work online without gaming the system.


That sparked an idea: using new tech like Nostr and Bitcoin to build a decentralized attention market for people who value control and businesses seeking real connections.

NextBlock is building a digital city-state with one simple rule: citizens own their attention.

This roadmap shows the journey of vision to reality.

From foundation to NextBlock City.

The Blueprint

01

The Manifesto

The Manifesto

The city's Declaration of Independence establishes NextBlock's vision of attention sovereignty and declares independence from attention harvesting.

The Foundation

02

The PROMO Protocol

The PROMO Protocol

The city's Constitution defines how access to your attention is protected when a citizen participates in the attention marketplace.

This is the open-source protocol specification that defines how attention marketplace data is structured, exchanged, and processed across the Nostr network, enabling any developer to build competing attention marketplaces while maintaining interoperability.

03

The Observatory

The Observatory

The city's calendar that uses Bitcoin's blocks to synchronize all city operations.

This is the first implementation of Telescope, the open-source protocol specification that transforms the Bitcoin's blockchain into virtual celestial cycles, enabling any developer to build truly bitcoin-native applications.

The Economy

04

Billboard Pre-Market: Market Makers

Billboard Pre-Market: Market Makers

The initial marketplace where citizens can enter bids for attention thus creating the buyers’ side of the marketplace. Citizens can earn through referrals to secure a more robust economy.

05

Billboard Pre-Market: Fixed-Rate Billboard

Billboard Pre-Market: Fixed-Rate Billboard

The expanded marketplace where buyers can invite new citizens to earn by watching their ads thus creating the seller’s side of the marketplace. Attention sellers can view and claim payments at fixed rates.

06

Billboard Market Open: Adjustable-Rate Billboard

Billboard Market Open: Adjustable-Rate Billboard

The dynamic marketplace where attention sellers set their own prices and attention buyers bid, with automatic matching by the Observatory every Bitcoin block.

07

Attention Marketplace

A public platform tracking attention as a commodity that provides historical data, market insights, and transparency for all marketplace participants.

City Life
