Vitalik proposes @graphprotocol as one alternative to Ethereum archive nodes for historical queries. This would lead to increased decentralization. (Archive nodes execute all historical transactions and take forever to sync)

Here's how I analyze crypto data these days: I use a combination of agentc.xyz, which sources its data from @graphprotocol, and GPT. Soon, all of this will be possible natively within The Graph.

I visited this place once. It was magical - from a dystopian sci-fi perspective. Nobody's shower worked because there was a water repair that needed all cubes to be removed to fix. Instead, there was a shower pod installed outside in the loading dock.

Don't know what MCP, A2A, ERC-8004, x402, and AP2 are, and now you're too afraid to ask? First of all, they're "protocols", which means they're guidelines or blueprints that, if everyone were to follow them, we could build some cool things. MCP: Makes it easy for LLMs to call

Currently, @semioticlabs is working with other Core Dev teams in The Graph to bring SQL/analytics queries to the protocol. agentc.xyz is a playground we built using LLMs to access DeFi data. Please sign up for the waitlist if you'd like to try it.

I was invited by the SEC to represent @CambrianNetwork at today's Crypto Task Force roundtable with Commissioner @HesterPeirce. The regulatory landscape for crypto in the US is evolving, and it's a privilege to be at the forefront shaping crypto's great leap into the future.

2024 is going to be a wild year for @graphprotocol. We will bring open-source large language models to The Graph as a data service. This will unlock things like natural language-to-web3 queries and decentralized web3 agents.
