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
-eWASM
-Storage pruning
-Simulation and emulation

(thread)
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.

media.consensys.net/you-can-make-m…

media.consensys.net/you-can-make-m…
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.

ethereum-magicians.org/t/hypothetical…
8/ Lastly, I just wanted to mention that various layer 2 scaling solutions are also being developed and are maturing rapidly:

*Plasma
*State channels
*STARKs

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.

0/ There has been a lot of misinformation spread surrounding Ethereum's upcoming issuance reduction - codenamed the #Thirdening

In this thread, I’ll explain the process that Ethereum issuance reductions go through before they can be considered “consensus”.

(thread)
1/ The issuance rate for Ethereum has been a constant talking point for years now. We can track discussions about a block reward reduction back to the 22nd of December 2016 when EIP-186 (github.com/ethereum/EIPs/…) outlined 3 possible issuance reductions and related schedules.
2/ This initial thread spurred lots of discussion in the community & many people joined in to offer substantive research on how a reduction in issuance would affect the security of the network. Discussions on this thread dropped off around August 2017 & continued in other areas.

0/ #DeFi Spotlight #2

Today, I’ll explain the types of DEXs in the world of Ethereum. There are 5 types:

*Off-chain order book (0x Relayers)

*On-chain order book (EtherDelta)

*Peer-to-peer (Kyber, AirSwap)

*Automatic market making (Uniswap)

*Child-chain (Gluon Plasma)
1/ First up is @0xproject.

0x is an open protocol for building DEXs. Developers build ‘relayers’ on top of the 0x protocol (such as @RadarRelay). 0x relayers have off-chain order books with trades happening on-chain and can also opt-in to share liquidity with each other.
2/ The original EtherDelta had an on-chain order book with on-chain settlement. It was the first widely used Ethereum-based decentralized exchange but due to everything happening on-chain, it was wildly slow and inefficient.

Dear @FBI @FBITampa I'm Richard. They lied under subpoenas to hide the tampered jail call.
@FBI @FBITampa I asked and fought so hard for the call. PG, the PD evaded, dodged, threatened, tried to make deals to avoid pulling the call once the case blew up the smear. I have all the emails. I had to call the jail to confirm calls. All on my pin. I called my sister. Once on another pin.
@FBI @FBITampa The jail confirmed the calls. It wascut short. Why lie under a subpoena? Honest mistake? The pin was the tell. Intimidation. The cold cased my mother case on Facebook the same day.

1. And now I'm going to tell a story. Another false flag. This time is to force @POTUS not to take the US army out of #Syria.
They already have a lot of experience (8 years) to make chemical attacks to accuse the Syrian government.
OH, and they even have a manual.🧐😲🤨
@RandPaul
2. ISIS terrorist? 😲Seriously?🤨 Have they investigated? 🤓And they already know who it was? 🧐Super efficient 🙃.

Preliminary reports say at least six people were killed & 19 injured by the explosion. US official: 4 US army Killed & 3 US army wounded.

3. ISIS took responsability?😲Seriously?🤨Have they investigated?🤓They already know who it was? 🧐Super efficient 🙃.

The Islamic State (IS, formerly ISIS/ISIL) took responsibility for the attack that reportedly targeted the US-led coalition’s patrol.

#Ethereum is about to undergo the #Thirdening - a reduction in issuance of new $ETH to miners from 3 ETH/block to 2 ETH/block, or a reduction of 33%. It will happen at block 7,080,000 as part of the Constantinople hard fork, which is estimated to be January 16th.
That's a bit like the US Federal Reserve saying, "we're about to reduce the number of new dollars we print next year by 33%." This is one step along the way to #Ethereum's eventual plan to have <1% annual issuance, as Proof of Stake and Serenity roll out. #Thirdening
When an asset's supply goes down (fewer miners selling newly-mined $ETH), assuming demand is the same (or higher), prices trend up. This is obvious when looking at $BTC price mapped against the #halvening, a similar event in $BTC where block reward halves, next one is May 2020.
