0/ There has been a lot of focus on Ethereum 2.0 (Serenity) over the last few months but not nearly enough focus on Eth1.0 and Eth1,x - I’m going to change that.

Eth1.x comes with four distinct upgrades:

-State rent
-Storage pruning
-Simulation and emulation

1/ Dapps like MakerDAO and Uniswap are providing real value for people *today* and they are both powered by Eth1.0.

Below is a couple of links that show what you can already do with Ethereum 1.0.


2/ Eth1.x is being developed in parallel to Eth2.0 so that dapp devs don't have to wait for Eth2.0 to deploy and grow their dapps.

High level overview here: docs.ethhub.io/ethereum-roadm…
3/ Currently, once a contract or non-contract account is deployed on Ethereum, it lives on the blockchain forever.

‘State rent’ is meant to curb the growth of the state of the Eth1.0 chain by requiring all accounts to pay a form of rent.

More info here: github.com/ledgerwatch/et…
4/ eWASM is meant to introduce the Wasm-based execution engine next to the Ethereum Virtual Machine (EVM) - which means they would exist in parallel on the Ethereum 1.0 chain.

eWASM would bring efficiency upgrades for Ethereum 1.0.

Find more info here: docs.google.com/document/d/1ph…
5/ Storage pruning is a sibling to state rent which aims to limit the growth of the Ethereum blockchain itself.

There are various solutions on how to implement this and they can be found here: gist.github.com/karalabe/60be7…
6/ Finally, a simulation and emulation framework is being developed to resolve questions about where Ethereum 1.0 is at, where it's headed and what we need to do to get there.

This upgrade is quite technical but you can read more about it here: docs.google.com/document/d/1pI…
7/ Extra resource here from @lrettig that goes over the hypothetical performance improvements that Eth1.x can bring.

8/ Lastly, I just wanted to mention that various layer 2 scaling solutions are also being developed and are maturing rapidly:

*State channels

These will further increase the functionality of the Ethereum 1.0 chain.
9/ As you can see, Eth1.x will (in theory) provide healthy upgrades for the Ethereum 1.0 chain while we wait for Eth2.0.

Other smart contract platforms are now competing with both Eth1.x and Eth2.0 - good luck.
