Meetup Digital Freedom - SEDI & KERI Protocol and eIDAS-based EUDI Wallet

Bio below, more on LinkedIN.Meetup – Comparing SEDI and the KERI Protocol with the eIDAS-based EUDI Wallet Model
(KERISuite: Free Open-source Identifier Systems Software under TrustoverIP Foundation that is anchored in LFDT)Monday June 29, 7:00 PM
Amsterdam area (exact location to be announced)
A meetup about SEDI and its supporting KERI protocol, and how this compares to the EUDI Wallet (eIDAS-based) that will be introduced across Europe.### In short
- SEDI = Model legislated in the State of Utah (US): State-Endorsed Digital Identity. The state endorses a digital identity, while the citizen remains in control.
- KERISuite = technical foundation for secure, self-controlled, persistent, cryptographically verifiable digital identity.
- eIDAS = European legal framework for electronic identification and trust services.
- EUDI Wallet = the European Digital Identity Wallet under eIDAS 2.0, enabling citizens and organizations to store and share digital credentials.
### The relation between these concepts
SEDI and eIDAS/EUDI represent two policy approaches to digital identity: Some US states versus EU.
KERI/KERISuite can be seen as a possible technical infrastructure for implementing such models in a privacy-preserving, decentralized, and verifiable manner.
SEDI places more emphasis on individual sovereignty and state endorsement, while eIDAS/EUDI focuses more on EU-wide interoperability and legal recognition.There are also concerns about the level of trust European citizens are expected to place in these systems.
The meetup is organized by the Permissionless Society Meetup Group and supported by the Linux Foundation Decentralized Trust (LFDT).
### Speakers
- Introduction to SEDI and the KERI protocol — Henk van Cann
- Presentation on the characteristics of eIDAS/EUDI from that perspective - {Speaker to be announced soon}
We are still looking for the second speaker.
Free entrance.
Doors open at 6:45 PM.The meetup starts exactly at 7:00 PM. At 8:30 PM we'll have a drink and a chat.

Increasing Trust on Ethereum with ENS and Enscribe
·OnlineOnline187 attendees from 150 groupsMost organizations on Ethereum are effectively anonymous. Contracts are deployed to nameless addresses, treasury wallets have no verifiable link to the org that controls them, and AI agents operate with no on-chain accountability. For protocols and DAOs trying to build credibility and operate transparently, this is a real problem — and it's one that existing tooling hasn't solved.
In this webinar, we'll walk through how organizations can easily create and manage on-chain identity for everything they deploy, using ENS as the identity layer supported by Enscribe (https://www.enscribe.xyz/). We'll show how protocols can name and manage their smart contracts, wallets, and agents under a unified namespace, making their on-chain presence verifiable, human-readable, and auditable.
