WHAT IS BLOCKCHAIN?

@leomrlima#J1Blockchain

Blockchain is…A decentralized distributed database

The underlying technology of Bitcoin

Allows anonymous, but trusted transactions

@leomrlima#J1Blockchain

Blockchain isn’t…A cryptography (or security) framework

The savior against all security problems(just look at how many different ”heists” we

got…)

HOW DOES BLOCKCHAIN ENABLE SECURITY?

@leomrlima#J1Blockchain

Let’s first define securityWhen talking about security, it can be VERY broad.”Security is the condition of the system being protected from unintended or unauthorized access, change or destruction.””Confidentiality is the property that information is not made available or disclosed to unauthorized individuals, entities or processes.””Integrity ensures that improper information modification or destruction is guarded against. ””Availability is the property of on-demand, timely and reliable access to and use of information by an authorized user.”

It also enables AVAILABILITY

PaymentsThings paying for things

Microtransactions

@leomrlima#J1Blockchain

Smart ContractsContracts that execute themselves entirely autonomously when certain conditions are met. An auction might automatically transfer deeds of ownership to the highest bidder after a certain time has elapsed, or father's contract might automatically send his son a set amount of money every year on his birthday.

This contains real code that is executed when conditions are met.

TraceabilityUnderstanding where each resource comes from

Real-time, reliable tracking of resources

THE FUTURE WITH JAVA

@leomrlima#J1Blockchain

What you can do now?https://bitcoinj.github.io/

IBM’s Hyperledger is coded in Java, and you already can work with Go lang (with Java coming soon?)

Microsoft Azure is very active in bringing blockchain to the masses.

Fad or Reality?It’s not a a reality…

... Nor a fad. It’s coming and for many use cases it will make sense.
