Chris Slee of AWH presents on the state of Blockchain technology projects in Central Ohio.

1. Dublin Blockchain Group

2. Agenda
• Networking
• Brief blockchain primer – Chris Slee @awhnet
• Local known blockchain projects
• 2 min standup of other projects / initiatives present
• Open discussion

3. Blockchain primer
• What is it really?
• Types of blockchain implementation
• Technologies

4. What is a blockchain (hype-free)
A way to store data that promotes trust and
transcends typical organizational boundaries.

Consensus
Work
There are many consensus options and ways to
reach consensus.
• Proof of Work
• Proof of Stake
• Proof of Elapsed Time (PoET)
• Simplified Byzantine Fault Tolerance (SBFT)
• Proof of Authority (PoA)
• Hypergraph
• and so so so many more

New data is added to change
the state of the payload
But both are the truth at the
time they were added to the
blockchain

16. Types of blockchain security
• Public
• Bitcoin, Ethereum and so many more
• Many are cryptocurrency based and focus on anonymous transactions
• Depending on the consensus model they pay money to complete consensus
and cost money to place data into a block
• Exchanges help transfer currency between types
• Business can use these public blockchain implementations to implement
smart contracts and reach a wide unfiltered audience.

17. Types of blockchain security
• Private
• Echo systems that allow members to do distributed transactions privately
• Membership is controlled and access is limited
• All transactions are accessible to all members for consensus
• Payloads are also accessible to all members

18. Types of blockchain security
• Private
• Tools and technologies

19. Types of blockchain security
• Secure
• Echo systems that allow members to do distributed transactions privately
• Membership is controlled and access is limited
• All transactions are accessible to all members for consensus
• Secure channels can be private and only accessible to the participants in the
specific transaction

21. Local Projects (that I am aware of)
SafeWire uses multiple sources of authentication to
help Title Agents eliminate wire fraud and keep their
customers’ funds safe.

22. Local Projects (that I am aware of)
Substratum is an open-source network that allows
anyone to allocate spare computing resources to
make the internet a free and fair place for the entire
world.

23. Local Projects (that I am aware of)
ProcessChain allows users to build and integrate
business processes into existing or custom, secure
blockchain instances.
