 of ZIP-213 that it is ok to make the miner \zaddr output public and that only users concerned with "post-quantum"
 privacy need to worry about metadata leakage. It gives no recourse to these users, and so in that sense Sietch
 can be seen an a valid defense against quantum computers. Further research is required to see what kind of

 Shielded Coinbase will drastiscally reduce privacy of \zaddr miners, because they will re-use the same \zaddr
 for every block and it leaks the \zaddr being mined to. The "normal" behavior of mining to a taddr first then
 sending to a \zaddr isolates metadata leakage to the taddr. The \zaddr of a miner is never disclosed publicly.
 ZIP-213 says miners should make a new address for every block but that simply will not happen because it's optional

 By using Timing and Value Analysis with Shielded Coinbase, an analyst can get a much better estimate on the minimum
 value a \zaddr likely has and how much funds pass thru it per time interval, as well as txid's to correlate to the

 ZIP-213 is a fascinating academic exercise which could be implemented with better privacy properties but less auditability,
 i.e. knowing exactly how much new funds are being mined in each block. Taking into account the ITM Attack in particular

 In summary, Shielded Coinbase was implemented by Electric Coin Company with little practical regard to increasing privacy on their
 blockchain, though it is an interesting technical peice of work. Since increased \zaddr usage does not translate into more profits,
