+## Very Much Frequently Asked Questions ❓
+
+### How much doge can exist? – So many puppies! 🐕
+Early 2015 (approximately a year and a half after release) there were
+approximately 100,000,000,000 coins.
+Each subsequent block will grant 10,000 coins to encourage miners to continue to
+secure the network and make up for lost wallets on hard drives/phones/lost
+encryption passwords/etc.
+
+
+### Such mining information ⛏
+
+Dogecoin uses a simplified variant of the scrypt key derivation function as its
+proof of work with a target time of one minute per block and difficulty
+readjustment after every block. The block rewards are fixed and halve every
+100,000 blocks. Starting with the 600,000th block, a permanent reward of
+10,000 Dogecoin per block will be issued.  
+
+Originally, a different payout scheme was envisioned with block rewards being
+determined by taking the maximum reward as per the block schedule and applying
+the result of a Mersenne Twister pseudo-random number generator to arrive at a
+number between 0 and the maximum reward.
+
+This was changed starting with block 145,000, to prevent large pools from gaming
+the system and mining only high reward blocks. At the same time, the difficulty
+retargeting was also changed from four hours to once per block (every minute),
+implementing an algorithm courtesy of the DigiByte Coin development team, to
+lessen the impact of sudden increases and decreases of network hashing rate.
+
+**The current block reward schedule:**
+
+1–99,999: 0–1,000,000 Dogecoin
+
+100,000–144,999: 0–500,000 Dogecoin
+
+145,000–199,999: 250,000 Dogecoin
+
+200,000–299,999: 125,000 Dogecoin
+
+300,000–399,999: 62,500 Dogecoin
+
+400,000–499,999: 31,250 Dogecoin
+
+500,000–599,999: 15,625 Dogecoin
+
+600,000+: 10,000 Dogecoin
