PARSEC is a Protocol for Asynchronous, Reliable, Secure and Efficient Consensus and is the world's first open source ABFT (Asynchronous Byzantine Fault Tolerance) protocol that can be used in a truly permissionless setting created by MaidSafe.

As a global decentralised data and communications network, the Safe Network has to be public and permissionless.

Unlike centralised systems there is no central body to act as a final authority on the state of the Network. Nodes on a decentralised system such as the Safe Network must therefore agree on network actions and state amongst themselves. Other decentralised systems such as BitCoin use blockchain to achieve consensus. However, there are a number of drawbacks with a blockchain based system notably the speed and cost as it grows - this is not a scalable option.

As far as we know, no other project has managed to ensure ABFT consensus in permissionless environments. This is technology that will power the Safe Network, the only truly next-generation decentralised autonomous internet that promises privacy, security and freedom by default.

PARSEC will be released under a GPL v3 licence (with linking exception). It will be free for anyone to build upon and likely prove to be of immense value to other decentralised projects facing similar challenges.
