The SAFE Network
by Maidsafe

Massive Array of Internet DiscsSecure Access for Everyone

Dirk Hoving Project SAFE Amsterdam

Special thanks to the Maidsafe team (especially @ioptio's framework) and the rest of the community.

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

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

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

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

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.

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

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

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)
