Eth News and Links
There’s an ongoing debate as to how much Eth1 should make breaking changes. In this instance, it’s about opcode repricing which might break code deployed on the chain, even though it is a bad practice to rely on static gas pricing. Sorpaas says no breaking changes please, though that’s opposed to the original sustainability movement which got mislabeled "eth1x." It’s not an easy debate in a decentralized ecosystem, though we have repriced opcodes before, because that’s necessary to avoid DoS attacks.

Latest What’s New in Eth2
Nimbus client update - working on launch mechanics and interoperability.
Spec v0.8.3 came out a week ago. updates to tests and networking.
phase 1 spec has Sep 30th target date for completeness
EF released a list of Eth2 grants, focused on client teams and interop/networking, as well as some R&D for light clients and also for phase1 proof of custody. There are also 3 open bounties: phase 0 consensus, Legendre PRF, and STARK friendly hash

Vitalik’s list of things that will change for app devs in Eth2. This is not short-term planning but things to keep in mind for the future.
FunFair founder Jeremy Longley with a detailed walkthrough of their state channel architecture and code
“A unified state channel specification for Ethereum” to lay “the foundation for a fully interoperable ecosystem” so that building on channels is as easy as possible for app devs
AdEx: How we built the largest payment channel network on Ethereum. 9 million transactions with only 13k USD onchain because they trigger a payment via channel for every ad impression. 10 cents in gas paid for millions of unidirectional, one-to-many payments. A good example of programmatic micropayments made possible by state channels.
Raiden light client v0.1
Vitalik: the dawn of hybrid layer 2
Optimistic rollup. Bonds/challenges to ensure valid transactions, instead of zk proofs, but easier to generalize for all applications and not just payments.

Torque: indefinite, fixed rate loans borrowed from bZx’s Fulcrum lending pools. “Torque did not require substantial smart contract development — the tools were already there”
Tokens / Business / Regulation
Synthetix: we were “dead wrong” in trying to develop on centralized chains like EOS because Eth network effects are real. As Robert Leshner notes, “there are now more developers building on Compound Finance than there are developers building on either EOS or Tron.”
Another Flippening: Tether active addresses is multiples higher on Eth than on BTC

For Week in Ethereum News’ 3 year anniversary, I did an annotated version of this week’s issue. Using Unlock Protocol, you can view it by purchasing a limited edition collectible NFT for the 3rd anniversary. Proceeds will be donated to things within the Ethereum ecosystem.
🎂 3 year anniversary 🎂
Just to repeat the advertisement immediately above: you can buy the limited edition NFT for 0.11 Eth which will unlock the annotated edition.
All proceeds will be back into Ethereum somehow, likely donated to a public good, at my discretion. And who knows, maybe there will be future benefits for the 200 NFT holders?
