Orie Steele is Cofounder and CTO of Transmute, a company developing IAM and Verifiable Credential solutions that
integrate Decentralized Identity for Enterprises.
He has a BS in Cyber Security and MS in Computer Science from Stevens Institute of Technology where he studied
social network malware and botnets between 2007-2012. He was an early engineer at Patient IO, a Techstars backed
startup acquired by Athena Health in 2016, where he helped develop and secure a care coordination platform that
connected nurses and patients.
In this talk, Orie will discuss the history of the Element DID Method, how it leverages the same Sidetree Protocol that is
used by ION on the Bitcoin Network. He’ll introduce the motivation for Element and ION, and then walk through the
core components of developing a working DID System, including topics such as wallets, signing, did resolution, key
revocation, and decentralization.
ABSTRACT
ssimeetup.org · CC BY-SA 4.0 International
MOTIVATION
BTCR / ETHR focused on SSI, but lacked
batching, causing challenges for
throughput and cost.
We’ve learned how to leverage
centralization better.
DID Methods contain a lot of duplication,
can we share a common protocol?
Supply Chain, IoT, FinTech & AdTech have
some use cases for DIDs that need more
scale to support.
ssimeetup.org · CC BY-SA 4.0 International
SIDETREE
Ledger agnostic protocol for anchoring
batches of signed JSON Patch
Operations resulting in a DPKI CRDT.
Batching supports higher throughput &
lower cost, but paranoid users can still
anchor themselves.
Open Source Apache-2 Implementations
for Bitcoin & Ethereum supported by the
Linux Foundation.
ssimeetup.org · CC BY-SA 4.0 International
ELEMENT
DApp / Light Node first approach, with a
wink toward paranoid users.
Client and Server UI Support, we want
user driven development ASAP.
Lerna monorepo of javascript modules
and project.
Slightly more functional than object
oriented.
Live testnet Progressive Web
Application.

WALLET
Hardware, Mobile, Web, API, Trusted
Execution Environment?
JWS vs JSON-LD Signatures, the case for
JSON-LD.
Shamir, Recovery and Usability.
Not all keys need to be in the same place!

RESOLUTION
A kind of reverse anchoring:
ledger -> anchor -> batch -> operation =>
did document
Data Poisoning, Spam and Errors:
How do trusted nodes handle bad data?
Why resolve a DID?
Signature Verification, Service Endpoints
and the Future of SSI.
