Ethereum is going through an identity crisis.
This is very visible at Devcon.
The booths only hosted the big projects.
There barely are any new dapps.
And even the big projects are struggling for users.
Meanwhile people are on their high horse looking down at memecoins. They don't understand that some things should just be fun.
Ethereum used to be fun.

The problems with Ethereum:
- Best minds in blockchain? Check.
- Largest dev community? Yep.
- Superior tooling? Absolutely.
- Most decentralized network? Indeed.
- Energy efficiency? Top-notch.
- Overflowing with dapps? You bet.

Solidity's try/catch doesn't deliver on its promise.
If the target is an address with no code (EOA), the execution reverts.
Solidity's try/catch does not protect you from reverts but causes the revert itself.

The reality is that, thus far, blockchain is still very self-referential. The technology largely addresses issues it created for itself.

Just witnessed the Multichain hack and it's clear that this is merely the starting point in a series of similar unfortunate events. We're dealing with a landscape where companies are utilizing libraries that apply techniques and technologies, the intricacies of which are beyond the grasp of the majority of developers.
We're specifically talking about fields like Zero-Knowledge Proofs (ZK), Multi-Party Computation (MPC), Threshold Cryptography, and Fully Homomorphic Encryption (FHE). These areas are rapidly emerging, but unfortunately, the understanding and mastery of them amongst developers haven't quite caught up.
As a result, we'll likely see an uptick in security incidents related to these technologies. Why? Simply because we don't have a sufficient number of professionals who possess the necessary knowledge to rigorously evaluate the implementations of these libraries. The key takeaway here is an urgent call for investment in education and resources to equip our developer community for these advanced technologies.
#Cybersecurity #Crypto #FutureTech #zk #ethereum
The lockup assets on the Multichain MPC address have been moved to an unknown address abnormally.
The team is not sure what happened and is currently investigating.
It is recommended that all users suspend the use of Multichain services and revoke all contract approvals related to Multichain.

I just saw this tweet from Solana where they say 400,000 tps.
It's true that in order to have transactions "per second" you need to process them. The problem was the transactions were in the queue, not yet processed.
1/ Solana Mainnet Beta encountered a large increase in transaction load which peaked at 400,000 TPS. These transactions flooded the transaction processing queue, and lack of prioritization of network-critical messaging caused the network to start forking.

balance = msg.value + previous balance.
Thus, `msg.value` can't be larger than `balance`.
It can, at most, be equal.
I like the `.transfer(balance + msg.value)`, enforcing the incorrect belief that msg.value is not included in `address(this).balance`.
