If you're just starting in Web3 security, Solidity and EVM are a great place to begin.
Learn the fundamentals, participate in a few audits, and then consider exploring other languages and ecosystems.
Solidity is highly competitive, but less crowded ecosystems could offer you a better opportunity to stand out.

This season every Celtics player got a handwritten note from a former player who wore his number. Dillon Mitchell got one from Ray Allen. Mitchell Robinson got one from Isiah Thomas.

Thanks for asking. Having hundreds of banking and capital markets leaders at a Chainlink event is helpful for the present but also future months and years. Behind the scenes, there were dozens of meetings with current / potential partners during the event. We had multiple new announcements during the week some of which have already prompted inbound requests from other firms. Sergey discussed the importance of LINK during his keynote including the expectation that some future partnership announcements would include purchasing, holding, and paying with the token. Also got some helpful feedback from community members during the event that we already started discussing later that day. More things I am sure but those are some quick Halloween thoughts.

🚨 VAN GOGH NÃO INVENTOU O CÉU DA NOITE ESTRELADA 🚨
🌌 Um estudo publicado na Scientific Reports pegou a pintura mais famosa do mundo e fez o que ninguém tinha feito: testou o céu dela com números. Resultado: a Lua minguante, Vênus e as Híades batem com a madrugada de 22 de julho de 1889, vista da janela do asilo em Saint-Rémy.
🎨 A data de junho de 1889, aceita há mais de um século, pode estar errada. E a leitura do quadro muda: não era um sonho, era um céu que ele viu de verdade.
POST NOVO NO BLOG!!!

ROAD TO Link:NYC 🗽
The first announcement in the lead-up to Link:NYC: Chainlink CustodySync.
More to come this week.
Turn on notifications, and tune in live on X and YouTube on October 29.
Introducing Chainlink CustodySync, a new solution that lets qualified custodians give their institutional clients access to DeFi lending markets, all while assets remain securely in custody.
With @Anchorage as the official launch partner, together we’re establishing a new standard for institutional DeFi.
CustodySync keeps custody and lending systems in sync across the full lifecycle of a loan:
→ For custodians: faster time to market and lower operational overhead, with custodian-managed controls
→ For lending markets: independent, verifiable data and a consistent risk framework
→ For institutions: passive capital becomes productive capital
More than $80 billion sits in DeFi lending markets. Meanwhile, the roughly $700 billion in digital assets under custody is less than 0.5% of all $250 trillion in traditional assets under custody. The opportunity to connect traditional institutional capital to onchain finance remains vast.
Large institutions have lacked a secure way of accessing these markets. Regulations require many of them to keep their digital assets with a qualified custodian, a firm that meets specific requirements for holding assets on behalf of clients, and custody systems were never built for DeFi. Even when custody and lending systems are connected, inconsistent loan valuations can trigger premature liquidation or delayed liquidations, exposing borrowers and lenders to significant financial risk.
@Anchorage, home to the first federally chartered digital asset bank in the U.S., is the first qualified custodian to adopt CustodySync, connecting its institutional clients to DeFi lending markets while their assets remain in regulated custody.
Institutional capital no longer has to choose between the security of custody and the liquidity of DeFi.
With Chainlink, it gets both.
