This shows the similarity of all difficulty algorithms. ``` T = target solvetime n = number of blocks in averaging r = a dilution aka tempering aka buffering factor w...
In **[a previous issue](https://github.com/zawy12/difficulty-algorithms/issues/49)** I discussed this in a different way, received feedback from Mark L, and discussed the possibility of RTT for BCH. This issue discusses everything that came...
**Update:** Digibyte's Multishield calculates the chain work correctly (without all the problems I discuss) by simply calculating the chain work of the most recently solved block as being the geometric...
Update: the following attack worked because they were using chain height instead of work to decide the tip. @ocminer sent me his node's log file. It shows the attacker did...

This describes how an alt coin can use a double-notarization scheme to import BTC or any other coin's chain work directly onto the alt chain to get BTC security directly...
**Takeaway:** ETH's new DA for Homestead works exactly like a good EMA despite only adjusting in tranches, enabling its use in situations where difficulty (timestamp) grinding may be a problem....
In the previous issue [BCH needs a new DA](https://github.com/zawy12/difficulty-algorithms/issues/47) I discuss the source of oscillations in DAs. This details the source of those observations. **Summary:** Simple Moving Average (SMA) difficulty...
[ **Edit:** This article is a little dated. I now have all the equations in integer format and the solvetime limits limits should be -FTL and +6 (instead of +7...
The POW for tx consensus should be different from the POW for coin generation. **POW for tx consensus** Theory and observation show POW consensus must be done by a POW...
