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 ?
