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)

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
