What Is LayerTree?
Bitcoin is a trillion dollar asset class consistantly going on 2 year, but the amount of users interacting on the network is far smaller, as certain transaction types really don’t make sense for on-chain transfers. If you need transaction finality, if you don’t have access to Lightning or you want to consolidate funds for the […]
What Is Bark?
The Ark protocol is an alternative scaling solution that offers different trade-offs than the Lightning Network. Like the Lightning Network, Ark offers multiple implementations to choose from, and as a developer, you can pick the one that fits your needs and gives your users the best experience. Bark is Second’s implementation of the Ark protocol, […]
Why Hashing Algorithm Changes Don’t Stop Centralised Mining
When the BLAKE2b hard fork split from Bitcoin, one of its core selling points was democratising mining by abandoning SHA-256d for an algorithm that’s friendlier to CPUs and GPUs; the change promised to sideline the industrial ASIC farms that dominate Bitcoin mining and hand the network back to ordinary miners with consumer hardware. It’s a […]
Beware Of BIP110/Blake BTC Scams
If you own Bitcoin, you should be aware of chatter over the last few weeks about “BIP110,” “Blake2b,” and a potential chain that will split away from Bitcoin’s main network with a proof-of-work change and act as a competing network. Opinions on this fork are all over the map — some people see it as […]
What Is Replay Protection?
When a blockchain network like Bitcoin splits into two chains through a hard fork, the two incompatible networks face a critical engineering question that determines whether the split is orderly or a genuine mess for users. Does the new chain implement replay protection? It sounds like a minor technical footnote, but its absence can cause […]
How Hardware Wallets Generate Entropy?
The recent draining of over 1000 Bitcoin from air-gapped COLDCARD wallets has many of us scratching our heads, wondering how this could have happened. While the dust still has to settle, and information will come out in the post-mortem of CoinKite’s operations, attention is now turned to all hardware wallet vendors. If one of the […]
What Is the RGB Protocol on Bitcoin?
RGB Protocol on Bitcoin (v0.11.1) is an open-source protocol for issuing and transferring digital assets directly on Bitcoin and the Lightning Network, without any change to Bitcoin’s base layer. It is not a third layer stacked on top of Lightning: RGB runs on Bitcoin’s base layer (Layer 1) and integrates natively with Lightning (Layer 2). […]
What Is Agentic AQUA?
A1 Lab—a division of JAN3—recently launched Agentic AQUA, taking another step in merging the Bitcoin economy with artificial intelligence and its growing infrastructure and impact on global markets. Leveraging Agentic AQUA autonomous AI agents have access to a native Bitcoin wallet, enabling them to send, receive, and manage funds entirely through natural language commands. Agentic […]
What Is Quantum Recovery of Bitcoin?
There has been a lot of chatter surrounding Bitcoin’s longevity as a network, as research on quantum computers gains traction, with some claims circulating that a viable device is less than a decade away, which, if true, will have massive implications for not only Bitcoin but the entire web from a privacy and security perspective. […]
Bitcoin Core v30 Has To Rollback
In an extraordinary egg-on-face moment (or moemish, as we call it in my native South Africa), Bitcoin Core developers issued an urgent warning on January 5, 2026, about a catastrophic bug in versions 30.0 and 30.1 that can completely delete wallet files and result in total fund loss. The severity of the issue prompted developers […]
