every pico is serverless and cloud-native, presenting an API that can be fully customized by developers. Because they’re persistent, picos support databaseless programming with intuitive data isolation. As an actor-model programming system, different picos can operate concurrently without the need for locks, making them a natural choice for easily building decentralized systems. W3C Press Release - Decentralized Identifiers (DIDs) v1.0 becomes a W3C Recommendation worth reading to see who contributed comments (and notice who didn’t)

For individuals in particular, DIDs can put them back in control of their personal data and consent, and also enable more respectful bi-directional trust relationships where forgery is prevented, privacy is honored, and usability is enhanced.

Pico is short for “Persistent Compute Objects.”

Why Picos

What are Picos?

Pico Engine 1.0 released in January

The project name, PICOS, is an abbreviation of “Privacy and Identity Management for Community Services”. The objective of the project is to advance the state of the art in technologies that provide privacy-enhanced identity and trust management features within complex community-supporting services that are built on Next Generation Networks and delivered by multiple communication service providers. The approach taken by the project is to research, develop, build trial and evaluate an open, privacy-respecting, trust-enabling identity management platform that supports the provision of community services by mobile communication service providers.

I’m excited to announce a new, stable, production-ready pico engine. The latest release of the Pico Engine (1.X) provides a more modular design that better supports future enhancements and allows picos to be less dependent on a specific engine for operation.

Summary: Picos are a programming model for building decentralized applications that provide significant benefits in the form of abstractions that reduce programmer effort. Here are ten eleven reasons you should use picos for your next decentralized application.
