Bitcoin’s original script language had several operational codes disabled in 2010 by Satoshi Nakamoto for security precautions. For years, critics claimed: “Bitcoin can never do smart contracts.” @rootstock_io answered that years ago: By combining merged mining with EVM compatibility, Rootstock brought Turing-complete smart contracts directly to Bitcoin security. That is why Money On Chain has run smoothly on Rootstock since 2019 without changing Bitcoin’s base layer.

“I think this is going to be one of the top use cases of Bitcoin in the next 10 years.” 🔗 @SDLerner on AI agents transacting with Bitcoin, and why determinism, irreversibility and permissionless settlement could make bitcoin:native a natural fit for agentic commerce. He also gets into what real Bitcoin security looks like, why defence in depth matters, and the new layers being built to expand what Bitcoin can do. @stonychambers @jakefentonBTC @BitcoinForCorps

3,000 stakers. 🚀 From 1,105 to 3,024 in just 9 months, that's 174% growth since January. Every staker is a vote of confidence in @rootstock_io and the future of Bitcoin DeFi. Thank you for building this with us. Onward. 🧡

"I think this is gonna be one of the top use cases of Bitcoin in the next 10 years." @SDLerner on why AI agents will value Bitcoin's determinism and irreversibility. This week on BFC Live with @JakeFentonBTC & @StonyChambers 👇

Melchizedek has spent the last two years building Kings Shop into something his community in Kibera relies on every day. A $250 Recoverable Grant could help him buy essentials in bulk, keep the shelves stocked and make that little shop go further. 🔗

80%+ of Bitcoin’s total hashrate now secures Rootstock through merged mining. That gives developers, institutions and users greater confidence to build and move capital on a network secured by the vast majority of Bitcoin miners. bitcoin:native security at scale. Full roadmap:

Forget price for a moment. Mining finance, hardware, yield, miner revenue and regulation are all changing at once. Tony DiCarlo shares five takeaways from a week in Hong Kong.

Hashrate is becoming something institutions can actually underwrite. At @BITMAINtech's WDMS Global in Hong Kong recently, @RootstockLabs Director of Institutional Propositions Tony Dicarlo joined the panel “From Hashrate to Balance Sheet: Bitcoin Mining as an Institutional Asset Class.” Much of the conversation around mining this year has focused on hashrate leaving for AI and HPC. Tony made the other side of the case: when hashrate leaves the network, difficulty adjusts and the miners that remain have an opportunity to capture a greater share of Bitcoin’s fixed daily reward. For a well-capitalised miner, that could make this one of the more interesting windows in years to grow hashrate market share. But the bigger shift is happening in how mining itself can be financed. Tony’s argument: hashrate is becoming real collateral, alongside hardware and Bitcoin, opening up new ways for miners to access credit and expand without selling BTC.

London next week 🇬🇧 On September 22, @BtcCorpDay brings senior decision-makers together under the Chatham House Rule to talk about how institutions are actually using bitcoin:native. Not whether Bitcoin belongs in a business, but how it’s actually being used: on balance sheets, in payments and settlement, as collateral, and across energy markets. That’s a conversation very close to what we’re building at RootstockLabs: infrastructure for Bitcoin-secured finance and onchain capital markets. Richard Green, Tony Dicarlo and @th3amcofficial will be there for the 2026 Autumn edition at The Honourable Artillery Company in London. If you’ll be in the room, find them.

One of our Rooties got a package last week that he didn’t order. “Are you expecting anything?” his wife asked. “Nothing,” he answered. So she opened it. Inside was an appreciation gift, sent by our People Team for the way he contributes to our culture of appreciation. What does that mean? We have a channel where anyone in the company can recognise good work they’ve noticed. Because sometimes the things that make a real difference are easy to take for granted: the person who always answers, the extra help, the fix nobody saw. We want people to feel appreciated, but also to get into the habit of appreciating others. It takes ten seconds to write a message. But being recognised for something you did well can stay with you much longer than that. He’s one of the people who takes those ten seconds, consistently. The last quarter, we sent 16 appreciation gifts to Rooties who do the same. Reward the work. Reward the people who make it happen.

What makes Bitcoin the safest decentralised network in the world? Watch @RootstockLabs CEO Diego Gutierrez Zaldivar @dieguito share his insights from the inaugural Xapo Summit. You can now watch the entire panel discussion here:

Eight years ago today. Rootstock was already talking about merged mining as a core part of its security model. Fast forward to 2026: 83.96% of Bitcoin’s total hashrate is securing Rootstock through merged mining.

“Without a time-delay lock, a single validation bug and a total loss become the exact same event, because funds move the moment software says ‘yes.’” @RootstockLabs Co-founder and Scientific Advisor @SDLerner spoke to @cryptodotnews about why time-delay locks matter for Bitcoin bridge security, and how @rootstock_io's PowHSMs use a 4,000-block (~36 hour) delay before signing a peg-out. Time can be a security control.
