Motocoin: The first proof-of-play cryptocurrency

**Motocoin** is an exciting new crypto-currency (launched May 20, 2014) that innovates with the *proof-of-play* scheme that rewards people with newly generated coins for quickly completing randomly generated maps in a fun 2D motorbike game similar to Elasto Mania. Unlike Bitcoin and others that rely on CPUs, GPUs or ASICs for *proof-of-work*, Motocoin relies on human skill and manual input. Join the early adopters, start mining and trading!

An alternative crypto currency for the cannabis industry.

Cannacoin is an internet based digital currency for the cannabis industry: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, Cannacoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Cannacoin. As such, it is more resistant to wild inflation and corrupt practices. With Cannacoin, you are your own bank.

XMG - Coin of the Magi

Coin of the Magi is a peer-to-peer global currency that enables instant payments to anyone in the world. XMG utilizes proof-of-work and proof-of-stake systems and is CPU and eco focussed - rewards reduce as hash increases.

#bitcoin under attack: twice someone tries to broadcast a bad block (proof of work failed: blocks start with only one zero .. 15 min later with not enough zero's). Glad my node rejects this joker immediately!

Bitcoin declining block rewards are pyramidal’ish - Why no-premine pure Proof of Work with constant block reward is the only viable distribution model for a cryptocurrency in the long term.

Question about Bitcoin protocol (Proof of Work, Block Reward & Transaction Limit).

I have just watched 3Blue1Brown's video on Cryptocurrency - He is very good at making complex ideas simple, btw!
I was wondering though. In the video, Grant said that the 'Zero's' on the Proof of work changes periodically, as the currency is decentralized, who decides when and how that changes?
Grant also mentioned that there is a transaction limit of 2400 transactions. Who set this limit, can it be changed (if so, who by?)
On the same note - the reward reduces every 210,000 blocks -- who make the reduction, or is it automatic?
Thanks a lot

Being the chain originating from the genesis block with the highest accumulated proof of work is only one of the metrics that makes Bitcoin Bitcoin. Edit and decide for yourself which has more Bitcoin-ness:

Prove me wrong: BCH is already "Bitcoin". It has the most cumulative proof-of-work among VALID SHA256 block chains

BTC may currently have most cumulative proof-of-work, but this is irrelevant because BTC has been invalid per the white paper (i.e. did not follow Nakamoto Consensus) ever since block 494,782. This is a factual determination of "validity" that can never be rectified by BTC unless someone rolls it back and restarts the chain at 494,783 with "2x" included. Therefore, BTC is not Bitcoin now, nor can it ever be going forward.
BCH is already Bitcoin, because it is the valid SHA256 block chain that has most cumulative proof-of-work.
With almost a $9k valuation, BTC continues to be something, but it's definitely no longer "Bitcoin".

"Although Bitcoin was intended to be a decentralized digital currency, in practice, mining power is quite concentrated ... [O]ur work further motivates the study of protocols that minimize 'orphaned' blocks, proof-of-stake protocols, and incentive compatible protocols." [abstract + link to PDF]

Bitcoin cash ABC vs SV proof of work comparison past 7 days (block 556304-557275)

ABC: 1,883,033.099104452 exahashes (filtered by AntPool, Bitcoin.com, BTC.com, BTC.Top, ViaBTC)
SV : 2,188,777.138620990 exahashes (filtered by BMG, CoinGeek, Mempool, okminer, SVPool)

SV has done 16.24% more proof of work this week. Any predictions for the next week?

The EDA on Bitcoin Cash does not break the definition of BTC in Satoshi's whitepaper: "the proof-of-work difficulty is determined by a moving average targeting an average number of blocks per hour. If they're generated too fast, the difficulty increases."

Bitcoin is the chain starting with the Nakamoto genesis block and having the most cumulative proof of work. Like it or not, that chain is Bitcoin Legacy/Segwit/Core.

You can chant "Bitcoin Cash is Bitcoin" all you want, but by definition you are wrong.
The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. — Satoshi Nakamoto

In a network segmentation, how does bitcoins Proof of Work solve how a block gets pushed to a network?

Say theres a major blackout and half of the network goes down, isolating these as "islands". If two parts of the network disconnect, i understand the longer chain will be be built off of once the other side of the network comes back on (as long as theres no double spending..), but how does the block itself get sent to the network? I think maybe I'm missing something?
Technical answers completely welcome and would be greatly appreciated (:

Block leaders, which produce the next block, are selected in a lottery-like format that corresponds directly to their contributed computing (i.e., hash) power to the process.

If the majority were based on one-IP-address-one-vote, it ... So proof-of-work concept one is block reward. Now, let's continue with the thought experiment. Assume for the moment that we can pick a node at random to propose a block.

Die Überprüfung dieser Informationen sollte so einfach wie möglich sein. Die Funktion des Arbeitsnachweises besteht darin, die Gültigkeit der Berechnungen beim Erstellen eines neuen Blocks zu überprüfen.
