TL;DR: small code differences, but many larger ecosystem differences
IIRC, Dogecoin is a fork of Luckycoin, which in turn was forked from Litecoin, which was forked from Tenebrix, which was forked from Bitcoin. As far as I can tell, the main differences to Bitcoin are:
scrypt hashing algorithm
1 minute block interval
accelerated reward schedule:
Full supply ...
It comes up that Bitcoin network has better security. Is that due to the hashrate ? If more miners start switching to Doge, wouldn't that solve the problem ?
Security in Bitcoin is not just about hashrate although it is one of the important things to consider. Other things related to security:
Bitcoin Core: One of the top 10 C++ critical open source ...
Shorter block times hurt decentralization
because they hurt smaller mining pools
because smaller mining pools depend on orphaning rate more
because orphaning rate depends on the number of competing blocks in unit time
since network connection quality becomes more important with higher orphaning rate
and of competing blocks, the larger miner with better ...
You'd need to name the wallet specifically. https://play.google.com/store/apps/details?id=org.dogecoin.production.blabla doesn't exist.
Assuming you were using a fork of the schildbach wallet, the general procedure based on the most likely fork is:
Your trouble will ...
One of the great challenges there is that the security vs time tradeoff for a given block interval depends on network parameters that are hard to observe and change over time. If you use too long an interblock interval, nothing bad happens-- security grows slightly slower. If you use a somewhat too short interval security is significantly damaged.
