Claim 11:
12. The system of claim 10 wherein said smart contract causes said Ethereum platform to form said Merkle tree comprises an algorithm:
(i) pairing up two adjacent certificates among said plurality of certificates;
(j) concatenating said two adjacent certificates and passing through a Hash function unit to form a second level leaf node where attributes of said two adjacent certificates are combined and stored;
(k) pairing up said second level leaf nodes;
(l) concatenating two adjacent leaf nodes at said second level and passing them through said Hash function unit to form a third level leaf node where said attributes of said two adjacent leaf nodes at said second level are combined and stored; and
(m) continuing steps (i) to (iv) until a root node is achieved.
