On the Exploitation of Blockchain for Distributed File Storage

Algorithm 1

Process for public auction.

1:Declare Member(Seller/ M parties /)

2:Declare Timeouts(/ timeouts /)

3:Declare Function contract auction(In &input, Out &output)

4:Set win = −1

5:Set btprice = −1

6:Set secdprice = −1 7:loop

8: for each j < m do

9:  if input.pat[j].value > btprice then

10:  Let secdprice = btprice

11:  Let btprice = input.pat[j]

12:  Let winner = j

13: else if input.pat[j].value > secdprice then

14:  Let secdprice = input.pat[j].value

15://The winner pays the bidder

16://The others are refused

17:Let output.seller.value = secdprice

18:Let output.pat[win].value = btprice − secdprice

19:Let output.win = win

20:for each j < m do

21: if j ≠ win then

22:  output.pat[j].value = input.pat[j].value
