Technology Recap:

Bitcoin:

  • Suhas Daftuar releases a PR that aims to reduce the bandwidth needed during initial header syncs when a block is found. This will improve synchronization of the blockchain with peers during the Initial Block Download (IBD) and more. 

  • Lightning Dev Kit, LDK, has published v0.0.111 which includes support for relaying onion messages! Onion messages are messages that don’t use HTLCs and can be sent across the Lightning network by nodes that support the protocol.

  • Jeremy Rubin posted to the Bitcoin-Dev mailing list including information regarding drivechains and trusted setup procedures. Drivechains are a type of decentralized sidechain where depositors send their mainnet bitcoins to a smart contract controlled by an anonymous miner who controls the production of blocks on the sidechain.  

Ethereum:

  • On September 14th, 2022 Ethereum successfully transitioned to PoS (Proof-of-Stake) via the Merge!! The chain was finalized after ~13minutes and the largest upgrade to-date was completed. 

  • Prysmatic Labs publishes v3.1.1 which contains a fix for a fork choice bug which could lead to a memory leak and gossip-sub optimization. 

  • Ethereum mainnet Slot 4700567 was the first ever block produced via mev-boost!

  • Volt Capital shares the inner-workings of The Merge, Surge, Verge, Purge…and Splurge. 

  • Erigon publishes a new release which fixes stability issues with PoS sync from a consensus layer node as well as supporting BSC hard fork. 

Other Chains: 

  • Prior to the Merge, the ETHW Core team released an open letter to the Ethereum community discussing the ETHW PoW (Proof-of-Work) chain and ETHW Mining Pool. 

  • Eddy Lazzarin of a16z Crypto shares their Zero Knowledge Canon which dives into the history of zero knowledge and the cutting-edge developments going on in the crypto ecosystem.

  • BitGo’s new Custodial Lightning allows customers to get up and running quickly to easily integrate the Lightning network into their services. 

  • Terence Tsao of Prysmatic Labs shares how 20 ETH validators were slashed within 3 hours due to attester equivocation. At the time, the minimum upfront penalty is 1 Ether. 

  • Zaki Manian returns to collaborating with the ICF as chair of the Technical Advisory Board. 


Hacks | Vulnerabilities | Exploits:

  • Wintermute was hacked for ~$160M on September 20th, 2022 potentially due to a wallet compromise via a vulnerability in Profanity which was disclosed by 1inch days prior. The attacker exploited the bug in Profanity to recover the private key to the Wintermute hot wallet. 

  • Shiba Inu, SHIB, leaked its AWS account credentials on a public code repository in late August. The team that found the vulnerability, Pingsafe, was unable to make contact with the team behind SHIB so publicly disclosed this info to the wider web3 community.

  • Nereus Finance lost ~$371K in a price oracle manipulation attack on Avalanche.

  • Gera Coin notified users that their private key was compromised due to a leak. The hacker proceeded to create two more smart contracts and mint tokens on Ethereum which resulted in a loss of $1.48M.

  • A New Free DAO reward manipulation exploit resulted in ~$1.25M in losses on BSC. 

  • During fuzzing in preparation for Ethereum’s Merge, a gas allocation error was found in Hyperledger’s Besu client which could result in a 0-day.
