Presentation of the SAFE network by Maidsafe. A decentralised scalable peer to peer internet with an integrated cryptocurrency without blockchain technology.

1. The SAFE Network
by Maidsafe
Massive Array of Internet Discs
Secure Access for Everyone
Dirk Hoving – Project SAFE Amsterdam
Special thanks to the Maidsafe team (especially @ioptio's framework) and the rest of
the community.

2. Why Maidsafe?
● Internet access is highly dependent on centralized servers
● Traffic peaks make websites slow and susceptible to DDOS.
● Cost of maintaining and securing servers causes monopolisation.
● Current internet is susceptible to censorship.
● Many centralised servers get hacked
● Blockchain tech is hard to scale, there must be a better way to
get consensus on ownership distribution

3. SAFE Network origins
● Founded by David Irvine in 2006. Inspired
by ant colonies, more than 9 years in the
making.
●
More is different: complexity at large scale
from simplicity at a small scale
●
Ants have different roles, can switch
roles, very adaptable
●
Specialization, adaptability,
communication and large numbers
●
Crowdfunded in 2014, bitcoin caused an
additional wave of interest

4. MAID
● Massive Array of Internet Discs
● Combining storage space, bandwith and CPU
power
● Hardware combined into one global cyberbrain
● Anyone with device+internet connection can
create vault
● MAID is what enables SAFE

6. Vault roles
● Storing data
● Data managers (managing data for other
vaults)
● Verifying and validating other vaults
● Groups of 32 randomly chosen of which 28
need to reach consensus.
● Nodes not behaving properly get outranked

7. Data distributing
● Data split into 1MB chunks
● Each chunk stored at least 4 times
● All chunks are stored in a location depending on the
hash of the chunk. Each chunk has a different
location.
● Self encryption. Need all chunks to decrypt the
whole.
● Parallel downloading of 1MB chunks makes data
retrieval incredibly fast.

8. SAFE
● Secure Access for Everyone
● Variety of encryption layers
● Privacy, security, freedom
● Self Authentication → no password information
leaves your computer
● Store data, privately, shared or public
● Build and use applications that interact with this
data

9. Safecoin and farming
● Integrated cryptocurrency. No distributed ledger in the
form of a blockchain.
● Proof of resource will farm you safecoin
● Uploading data to the network costs safecoin. Safecoin
is recycled and given back to the network.
● 10% of farming rewards go to app developers
● Micropayments, instant verification
● Reward content creators, cut out the middleman

10. The way forward
● Installers for linux coming this or next week. Other
operating systems following shortly.
● Development bundle 1 being released this or next
week (simple vaults, LAN only)
● Couple of sprints for development bundle 2
(community run vaults and farming integration)
● Development bundle 3 (safecoin full
implementation, POSIX API and messaging API)
