These are the slides used to demonstrate the need of hybrid blockchains. To secure personal information we need Decentralised Identifiers and off-chain verifiable claims. To securely share these claims, we use an private sidechain which are GDPR compliance and removable with consensus.

4. What is Smilo
Hybrid blockchain platform with a conscience:
Hybrid: Built to facilitate applications requiring public and private transactions, -smart contracts and
-decentralized applications. We are as such offering a scalable and decentralised alternative to
permissioned platforms such as Corda and Hyperledger for secure transactions in both public and private
domain, on a decentralised platform.
Blockchain platform: Latest generation blockchain platform, based on the Smilo BFT+
consensus mechanism and the Smilo Network Protocol protocol (SNP), providing exceptionally secure,
scalable and speedy transactions.
With a conscience: Smilo will be the platform to facilitate current and future applications in the
areas of privacy, transparency, anti-fraud and corruption in a way that is safe, affordable and sustainable.
All on a decentralised platform that is state of the art in terms of performance and security.

10. 10 Hybrid
A thing made by combining two different elements.
A hybrid blockchain combines the public and private elements in one chain.

12. New possibilities_______
12
This opens new doors
The platform is available for everyone
- No racism
- No exclusion
- Transparent
But privacy is protected
- Some things only need to be known between you and dedicated other
parties.

14. Decentralized Identifiers(DIDs)_______
14
Decentralized Identifiers, a portable and a unique identifier
where you can store credentials.
Credential is a set of one or more claims made by the same
entity. Like a driver license, passport, name, birth certificate etc.

15. PROBLEMS WITH THE DAILY
CREDENTIALS
- EASY TO COUNTERFEIT
- TOO LOSE OR GET BROKEN
- TOO MUCH UNNECESSARY INFO
- EXPENSIVE TO REPLACE OR REQUEST
_______
15

16. Goals
- Decentralization
- Self-sovereignty
- Simplicity
- Privacy
- Extensibility
- Proof-based
- Security
- Discoverability
- Interoperability
- Portability
_______
16

17. Decentralization
Dids should eliminate the need for centralized
identity management authorities. Instead, a person
must have complete control over his or her id.
_______
17

18. Self-sovereignty
You are responsible for what information
(claims) you request and share.
_______
18

19. Simplicity
DIDs are user-friendly because they are
authenticated in a different way, so that passwords
are no longer needed.
_______
19

20. Privacy
DIDs should enable entities to control the privacy of their
information, including minimal, selective, and progressive
attributes or other data.
_______
20

21. Extensibility
The possibilities are endless. The
extensibility allows developers to add or
expand functions.
_______
21

22. Proof-based
DIDs should enable the DID subject to
provide cryptographic proof of
authentication and proof of
authorization rights.
_______
22

23. Security
DIDs must offer sufficient certainty for
the certainty and safety of dependent
parties.
_______
23

24. Discoverability
DIDs are easy to use. Anyone can learn
to deal with it. Data is also stored in
such a way that it can easily be
retrieved.
_______
24

25. Interoperability
The ability to let countries and
organizations work and communicate
together.
_______
25

26. Portability
DIDs are system and network
independent. So that they can always be
seen everywhere.

28. ERC 725_______
28
ERC 725 is a standard for
publishing and managing
an identity through a smart
contract on an evm-based
blockchain, such as Smilo
and Ethereum.

29. Verifiable Claims_______
29
- Issuer- The entity that creates
a claim and associates it with
a particular subject.
- Subject- The entity about
whom a claim is issued.
- Holder- The entity who
controls a particular claim.
Often the subject of the claim,
but not always. A holder is
typically the initiator of the
transmission of a claim.
- Inspector- The entity about
whom a claim is issued.

30. Result
- Much easier (digital) life
- No Usernames/passwords needed
- Account information no longer needs to include your personal information
- No more manual paperwork
- No more wait time
- No more wrong documents
- Security, Privacy and inclusion
- No more phishing and spoofing
- Mutual authentication
- No more spam
- More privacy
- No exclusion
