The Ergo block interval is 2 minutes, and for the first two years, each block will release a total of 75 Ergs to be shared between the miners and the Treasury (Treasury discussed below). But starting at year 2, the emission rate will fall by 3.0 Ergs and after that further decline every three months by an additional 3.0 Ergs, which will result in an end to emission eight years after launch.
In Ergo, just like Bitcoin, Ethereum, and other blockchains, blocks are broken into sections. In Bitcoin, there's simply a block header and the transactions themselves. But in Ergo, we have some extra sections that enable new functionality:
- Proofs of UTXO transformation
The 'extension' section contains certain mandatory fields (including links for NiPoPoW, once per 1,024 block epoch) and parameters for miner voting, such as current block size. It can also contain arbitrary fields.
What this means in practice is that different types of nodes and clients can download only those sections of the blocks they need – reducing the demands for storage, bandwidth, and CPU cycles.
