all the gosh knows how many other coins that emit the same number of coins per block forever
I don't know of any besides Grin.
I know Doge currently has a fixed block reward, but over the first year rewards were 20x higher.
Hmm you joined the forum in 2013, maybe they were all before your time?
Off the top of my head I can think of CoiLedCoin (CLC) and I think maybe GeistGeld (XGG) too, and of course GRouPcoin (GRP)'s 50 coins per block forever followed by DeVCoin's 50,000 coins per block forever which admittedly can be marred by failing to provide viable distribution files since if it cannot find a consensus as to which projects to send 90% of the mined coins to it creates only the 5000 the miner gets.
Are there really no others? TeneBriX (TBX)'s 7 coins per block forever is of course marred from the outset by its pre-mine, and FairBriX (FBX) didn't just correct the pre-mine I think but also put some kind of halving too.
I cannot recall offhand what United Frederation Credits' emission schedule is, does it have some halving or something too?
Coins which combine staking alongside proof of work of course might even cause an even more fair emission rate as in closer to the same percent of existing coins emitted generation after generation, rather than a smaller and smaller emission for each generation of the total thus far minted...
I had not realised though that a constant number of coins emitted per block is truly rare, I am pretty sure there are other examples I have stumbled upon over the years.
I think one of the currencies used by the designated-evil civilisations in the
Galactic Milieu also has constant emission, I know XDC has halvings so presumably it would be CRY, if either, that is just going to go on pumping out a constant emission forever.
I still feel sure there are others I cannot recall, not adopted by the Milieu, that over the years I had noticed as yet another constant-emission coin.
Wow I guess satoshi's vision of halvings really has had a lot of impact all this time eh?
