PREVENTS DOUBLE SPENDING BY USING A COMMUNITY CONSENSUS MECHANISM. NODES ARE INCENTIVIZED TO ACT HONESTLY TO MAINTAIN A COMMON, UNIVERSAL LEDGER SYSTEM; ETH
SOPHISTICATED SOFTWARE/CONTRACTS WITH PROGRAMMABLE BUSINESS LOGIC THAT PAYS OUT BASED ON A PRESET SCHEDULE; LINK
PROVIDES RELIABLE TAMPER-PROOF INPUTS AND OUTPUTS FOR COMPLEX SMART CONTRACTS ON ANY BLOCKCHAIN USING A COMMUNITY CONSENSUS MODEL FOR VERIFYING EXTERNAL DATA WHERE THOSE VALIDATING STAKE THEIR OWN COLLATERAL AS IN INCENTIVE TO ACT HONEST; 80+% OF ALL SMART CONTRACTS ARE GOING TO NEED QUALITY EXTERNAL DATA FED TO THEM.
