🚨 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.

The more I think about it, the more I love this trade for Boston.
If things go well, I could see PG opting out next summer and taking 3 years/$75M to finish his career here.
Two incredibly valuable firsts AND a potentially better fit at $25M/year instead of Brown at $70M+.
Brad Stevens is a demon.

OpenZeppelin is now officially a part of S&P Global.
The acquisition we announced in September is finalized. OpenZeppelin’s decade of securing and building the infrastructure onchain finance runs on now meets @SPGlobal's more than a century of helping markets understand risk. Together, we can help institutions and builders move onchain with greater confidence.
To our clients and to all the users of OpenZeppelin open source tools:
• OpenZeppelin Contracts and all our open source applications and tools remain open source, free and publicly maintained on GitHub.
• Security audits, secure development work and ecosystem programs continue with the same team, brand, quality and customer experience, now backed by S&P Global’s research capacity, market data and institutional reach.
For the last decade, OpenZeppelin has set the security standard for onchain finance. Now we take it to the scale of global finance.

Eu vi o Exército transformar a vida de muitos jovens da minha turma. Vida que desde muito cedo poderia ter sido diferente, se tivessem tido uma oportunidade como essa.
Feliz por ver essa molecada crescendo com valores, disciplina e hierarquia desde novos.
🚨🔵 Os formandos da terceira série do Colégio Policial Militar de Blumenau fizeram uma última prova diferente antes de deixar o Ensino Médio, e ela terminou em choro.
Os alunos correram pelas ruas em um dia de chuva, foram vendados e levados em um caminhão-baú até um campo. Lá, em formação e ainda com os olhos cobertos, a turma ouviu o recado de um dos militares do colégio: "Aqui acabou, mas lá fora só vai começar".
Depois veio a ordem para retirar a venda e dar meia-volta. Do outro lado do gramado estavam os pais e familiares, com flores e cartazes. Pais e alunos correram para os abraços.
A turma chegou ao colégio em 2020, quando eram os alunos mais novos da unidade. "Carregarão para sempre o peso de terem se formado no Colégio Policial Militar", disse o militar.
O vídeo publicado pelo colégio passou de 100 mil visualizações. "De novo chorando por pessoas que não conheço, lindo demais", diz o comentário mais curtido. Outra pessoa contou que assistiu a tudo da janela de casa.

In short: after Glamsterdam, some calls that used to fail out of gas can now complete, and contracts built on the old behavior can make the wrong call.
