A simple explanation of the cryptography underlying Spark, a layer 2 built using statechains.

Stablecoins are ultimately capped by a ceiling that Bitcoin is positioned to smash right through. They are not an existential threat to Bitcoin.

Being able to transmit value like information, as fast as a text message, has profound implications for society. Bitcoin unlocks that.

Ark and Spark revolutionize Lightning Network’s scalability in 2025, slashing on-chain transactions with shared UTXOs for fast, cheap Bitcoin payments. Their interoperable, trust-minimized designs overcome channel factory hurdles, cementing Lightning’s role in Bitcoin’s layer-2 future.

A look at the upsides and downsides of a tighter integration of USDT into the Lightning Network.

Bitcoin's use as a store of value or a means of exchange is not mutually exclusive.

Lightning is becoming a translation layer, or a glue, that holds together different systems built on Bitcoin.

And here's what to do about it.

As recent developments on Bitcoin, Ordinals, inscriptions and the BRC-20 protocol are drawing controversy, but they can’t hurt.

Developing Lightning as a Service (LaaS) removes friction from bitcoin and gives users the experiences they crave.
