Into The Future

Act - 2

Web 2.0

How it can be?

Ethereum - Agreements & relationships

Swarm - Publication & distribution

Whisper - Messaging & bulletins

Swarm More agile - Peer-steering & adaption More secure - Encryption, possibly

onion routing Better incentivisation - Zero-trust logging

of contributions

Whisper• Messaging - Think UDP• Transient publicationThink broadcast

• Configurable TTL - Not strictly async or sync

ÐApp – distributed application

etp://anydappurl

Example: Marketplace

So , what we are going to get ?

Web 3.0 ?
