Be very careful out there today. A Great White Shark spotted off the Lighthouse point. On Nantucket Island and Chatham Beach.

If there are seals… there will be Sharks.

Blurt : A Peer-to-Peer Electronic Cash System

Abstract.

A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party (Blurt Wallet, Steem Wallet, Hive Wallet + Wallet of Satoshi) to another without going through a
financial institution.

Digital signatures provide part of the solution, but the main
benefits are lost if a trusted third party is still required to prevent double-spending.

We propose a solution to the double-spending problem using a peer-to-peer network.

The network timestamps transactions by hashing them into an ongoing chain of
hash-based proof-of-work, forming a record that cannot be changed without redoing
the proof-of-work.

The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power.

As long as a majority of CPU power is controlled by nodes that are not cooperating to
attack the network, they'll generate the longest chain and outpace attackers. The network itself requires minimal structure. Messages are broadcast on a best effort
basis, and nodes can leave and rejoin the network at will, accepting the longest
proof-of-work chain as proof of what happened while they were gone.
