The era of Treasury "money glitch" (cheap debt/equity arbitrage) is OVER. Investors have made it clear: to justify a premium in 2026, they demand treasuries that offer utility and yield, not merely passive exposure.

"The bull case is just a hope, while the bear case is an accounting certainty." Maestro CEO @MarvinDefi doesn't sugarcoat the math. In the latest feature from @Cointelegraph, he breaks down the structural risks facing Strategy’s Bitcoin model as we head into 2026. While

Rootstock, Babylon, Taproot Wizards, BOS, IOG; Bitcoin and Cardano legends in one room talking about collaboration. We've turned a page, bury the hatchet. Let's change the game together.

Why XRP and ADA are pumping while the rest of the top 10 is red? Is this institutional money or retail? Is there some insider scoop or new regulatory news that is fueling this? Genuine question

The first-ever Bitcoin <> Cardano transaction has been completed. And it's a major unlock Why? Because Cardano can now act as a DeFi layer for Bitcoin, tapping into over $2T in dormant BTC liquidity This is powered by the Cardinal protocol TLDR on how it works: - Your

UTXO isn’t harder to build on, it’s harder to break. People say UTXO is too complex But here’s the truth Complexity for devs = security for users. > No shared state to corrupt > No domino-effect exploits Yes, it’s harder to build. But it’s also 10x harder to hack That’s the

Bitcoin ecosystem is warming up to the idea that a smart-contract standard that is UTxO-native, Turing complete, and provably secure is pretty dope.

BREAKING: The founder of Cardano @IOHK_Charles just reversed his stance on Bitcoin and announced that Cardano L1 is pivoting to become a Bitcoin L2
Readers added context
Cardano remains a L1. It'll communicate with BTC in such a way that from BTC point of view it will work as an application layer or L2. This will happen through the BOS Grail Bridge which allows for trustless bridging and is thus very different from usual bridging solutions assets-global.website-files.com/661e3b1622f7c5…

So many Cardano big brains in one place talking about the future of Mithril, Hydra and ZK on Cardano. Big ideas were discussed like "shallow" nodes with Mithril and ZK proofs .

There are a lot of questions regarding the mechanics of @BTC_OS . Specifically does the ZK proof actually get verified on-chain by the miners? Short answer is yes. The team at BitcoinOS found a clever way to allow Bitcoin scripts to verify these proofs. more details delow ⬇️

Most DeFi hacks were designed preventable! Billions lost to: – Reentrancy – Global state bugs – Over-composable contracts Why? Account based models have a huge design flaw; shared global state as well as lack of true self custody. UTXO is different – Stateless execution –

‘Cardano is not as secure as Ethereum because it lacks slashing!’ This is absolutely false! Firstly, what is Slashing? Locked ETH in Validators can lose a portion of their stake, "slashed," for dishonest behavior. Cardano’s Nakamoto consensus doesn’t need slashing for

The Bitcoin X Cardano Integration is much bigger than it appears But how? First let me explain Through the @BTC_OS grail bridge powered by zk cryptography, users can securely bridge assets into Cardano fostering interoperability. This means that Cardano can tap into deep
