You see things; and you say, 'Why?' But I dream things that never were; and I say, "Why not?" (George Bernard Shaw - irischer Dramatiker und Satiriker, 1856-1950) no rest for the wicked - catch me on the flipside ;)

TEAM - Who are we?
Our current annual budget per person:
If you like our work please help to fund us :-)
~£20,000.00
£0.00
(from Ethereum Foundation)
(from other sources)
CONTEXT - How can I trust this does what it is supposed to do?
???
WITHOUT "verified source codes":
CONTEXT - How can I trust this does what it is supposed to do?
Ethereum = slow & expensive
alternative hosting solution like
AWS, Heroku, Azure etc.
ETHEREUM is NOT TRUSTLESS
???
PROBLEM
only few thousand
verified source codes
nowhere to browse
smart contract sources
no incentive to
share sources
no neutral place
to store sources
Very few verified source codes
SOLUTION
search interface for solidity source code
PRE ALPHA - First release is planned for late autumn (beta)
WORKSHOP

+ workshop time
ARCHITECTURE
p2p search engine architecture
Consists of different kind of network nodes:
1. DHT nodes - help with discovery
2. source code nodes - collect source code
3. target list nodes - collect crawler targets
4. crawler & scraper nodes - add new source codes to the network
DHT nodes
piggy back on existing DHT system for discovery
ARCHITECTURE
target list nodes
They maintain and synchronize a list of crawlable targets
ARCHITECTURE
source code nodes
They maintain and synchronize a list of source codes
ARCHITECTURE
scraper & crawler nodes
They crawl and scrape all targets to add new source codes to the p2p database system
ARCHITECTURE
next: shared indexing work
goal:
all active p2p search nodes will share the work of
updating and maintaining indexes
to improve search performance
