as a proof-of-work function, but a stretched key-derivation function, and while it is by design expensive to compute with high iterations, it can not be used to make an efficiently publicly auditable proof-of-work, as verifying costs the same as creating. (A lot of hashcash design choices are motivated by simplicity). Even one ecdsa signature is slower than one Scrypt(1) verification which is done once per block, and there are many transactions (and so ecdsa signature verifications) to verify within a block. In hardware the time-memory tradeoff would be optimized to find the optimal amount of memory to use, and it is quite possible the optimal amount would be less than 128kB.

The differentiator and why people might choose Scrypt rather than pbdf2 is that Scrypt's inner hash uses more memory so the GPU (or theoretical Scrypt asic/fpga) advantage in password grinding is reduced compared to CPUs. One likely side-effect however would be that it would introduce more memory or pre-computation tradeoffs which could make asics unprofitable, or give advantages to people with large resources to do the pre-computations. Do not post your Bitcoin address unless someone explicitly asks you. This does not use the key-stretching feature of Scrypt so mining is not actually using Scrypt directly, but only the inner Scrypt hash (accessed by setting the iteration parameter to one iteration). Bitcoin protocol without overwhelming consensus is not permitted. For example the EFF "deepcrack" DES cracker project built a hardware brute force machine capable of breaking a DES key in 56 hours to make a political point that 56-bit DES was too weak in 1998 at a cost of 250,000 (plus volunteer design time). Note also a mitigating factor is that it is considered that hashcash-Scrypt(1) should offer less speed up from asic implementation vs GPUs than hashcash-SHA2562.
