Dagger-Hashimoto is the initial version of the Ethereum's Ethash proof-of-work algorithm. It was designed by Vitalik Buterin and the Ethereum team by combining the prominent features of the Hashimoto algorithm and the Dagger algorithm. Dagger-Hashimoto is a memory-hard algorithm that was designed to be ASIC-resistant.
Dagger-Hashimoto was one of the fastest algorithms at the time of its genesis. It also provided cryptocurrencies with ASIC-resistance, that was a huge advantage in comparison to its popular contemporaries. However, not a lot of coins are still powered by the Dagger-Hashimoto hash function. Most of the coins that started with it later changed their hashing algorithm to Ethash alongside the Ethereum network.
Both algorithms (Dagger-Hashimoto and Ethash) were later updated separately and are not currently considered to be the same algorithm. However, they are still sometimes considered to be synonymous.
Block time defines the time it takes to mine a block. On any blockchain, there is an expected block time, and an average block time. The Ether-1 Network has an expected block time of 13 Seconds but has an average block time which fluctuates between 10-20 Seconds.
Block reward refers to the new ETHO that are created when a new block is found on the network.
Miner reward refers to the new ETHO that are awarded by the blockchain network to eligible cryptocurrency miners for each block they mine successfully.
Node reward refers to the amount of ETHO awarded by the blockchain network to eligible SN/MN/GN for each new block found on the network.
This is the amount of ETHO per block which is automatically sent to the Ether-1 Developer fund - These coins are used to pay for anything from: Exchange listings, Developer fees, Staff paychecks etc.
A Network ID is essentially a Unique ID for each Ethereum fork.
Remote Procedure Call Sever (RPC Server) allows users to interact with an Ether-1 Geth Node run by the official Ether-1 Team.
