Ctf proof of work
WebChallenge The server first asks for a proof of work. Then you need to specify an index between 1 and 3. This index determines the Generator that will be used as your LFSR. The server will then send you 5 times 1000 bytes of the LFSR (so 40000 LFSR output bits). It will also return a hash of the key you need to guess as a hint. WebSection 1 - The CTF Levy The levy is calculated at 0.2% of the value of construction work (including GST) where the total estimated value of the work is more than $20,000.00. The levy applies to construction work whether or not a building permit is required and must be paid before construction work starts.
