The process of tendering, even if it is paper based, it raises several legal issues. The main concept of tendering
is to befair and transparent and requires trust between both the tenderer and bidder.
The use of electronic medium in tendering raises the need for not onlylegal issues but also the security threats
that come up when moving to an open network environment.
A block chain is a growing list of record, called blocks, which are linked using cryptography. Block chain
techniques maintain transparency of data on all its peer on the network.
In the current system of e-Tendering: The tendering organization with developer level access can see the
tender whenever they want, they can read bids before the deadline of tendering process, and it takes lot of time to
complete the procurement action.
In our project using block chain we are making the e-Tendering process secure in the following manner.
Tendering organization cannot change the tender once it is based on block chain, it cannot read the bid until a deadline
is expired, and the bidders cannot see or change the bids of other organizations.
