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 s...
We introduce thematchtig algorithmthat computes a character-minimum SPSS for a set of genomic sequences. While former heuristics (ProphAsm, UST) did not allow to repeatk-mers, our algorithm explicitly searches for all opportunities to reduce the character count in the SPSS by repeatingk-mers. ...
