What is the probability of a given Bitcoin price target?

Understand how Bitcoin prediction markets work: https://t.co/WxbXj5ac82

[Glimpse @GlimpseMarkets]

Imagine combining the mechanics of a prediction market with the look and feel of a professional crypto trading platform.

Instead of simply guessing whether Bitcoin goes up or down, you forecast where its price will be at a specific time using event contracts.

Trade probabilities. Forecast the future.

When you hear “multi vendor multisig” it sounds really difficult and scary.

It’s doesn’t have to be. You get this out of the box with Casa with one hardware wallet, and if you were already using that HWW you will find the UX easy.

HWW + phone + Casa.

No KYC, easy app.

Lightning Network 2025 Stats: Year in Review ⚡️📊

Across metrics, Lightning showed robust growth with all the hallmarks of health and strength with its expansion.

2025 set a solid foundation for Bitcoin's MoE proliferation in the years ahead.

Let the data show you👇

[Vikash Singh @vsingh_5]

In our latest research work, we tackle the tricky challenge of verifying attestation of Lightning channel balances! As Lightning continues to grow in volume and institutional adoption, it will be increasingly desirable for companies to be able to cryptographically attest to the Bitcoin they have in Lightning channels for auditors, proving solvency, credit, and lending. Offchain payment channels are unable to be verified onchain via regular digital signatures, however they do have native APIs that report balances. Running Lightning nodes in Trusted Execution Environments (TEEs), creates strong guarantees of the integrity of the software being run, which can be combined with proofs of delivery (zkTLS, etc), resulting in a strong layered approach to generating and verifying attestations.

We test onboarding open source repo's to Hive regularly and the latest felt like magic (https://t.co/4yh3vXAMTr).

Paste in a github URL and get:
- code is parsed into a graph database
- test coverage analyzed
- agent friendly documentation created
- scan for exposed secrets
- an agent spins up your app on VMs
- PRs for missing tests appear

Hive will make managing a product fun again.

[Nick Neuman @Nneuman]

Recently I was called by someone pretending to be Coinbase support, trying to steal bitcoin.

I decided to turn the tables on him and ask him about being a scammer.

Things got wild - he completely changed his personality & told me everything.

1/ ⚡️ The Lightning Network is key to Bitcoin’s scalability, but traditional metrics like capacity & node count only scratch the surface. There’s a better way to measure network health: Max Flow.

[Simanta Gautam 🏔️ @simanta]

So excited to announce @Strata_BTC
