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 […]
What Is The BLAKE2b Hard Fork?

If you’ve seen the term “Blake2B” floating around Bitcoin forums and X threads, and you’re wondering what on earth these guys are going on about, it’s almost certainly BLAKE2b — the proof-of-work algorithm at the centre of Bitcoin’s recent hard fork attempt. It’s been one of those months in Bitcoin where a year happens: from […]
Liquid Activates ELIP-203 Hard Fork

On June 1, 2026, Liquid Network successfully activated ELIP-203, a coordinated hard fork that removes a constraint from the Bitcoin sidechain that was part of its legacy launch, and is a sign that the chain is looking to expand its reach beyond being just another way to move Bitcoin off-chain. Lightning has already captured the majority […]
What Is The eCash Fork?

In August 2026, Bitcoin will undergo a fork with a new chain emerging if Paul Sztorc and Layer 2 Labs follow through with their plans. It’s been a while since we’ve seen a fork following the Bitcoin Cash split from the network in 2017 (along with BTG and BSV, which even fewer people care about, […]
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. […]
What Is Citrea?

Bitcoin has proven it’s the only real innovation in the blockchain space, while altcoins have made for interesting experiments with real money, real lives and real crimes, no other chain has come close to Bitcoin. With each 4-year (bull & bear) cycle that goes by, Bitcoin continues to lap these other ecosystems, draining liquidity, users, […]
Why Have Bitcoin Fees Been So Low?

In a surprising turn of events for Timechain observers, Bitcoin has managed to maintain relatively low transaction fees despite breaking new all-time highs in value, market capitalisation, and hash rate. This phenomenon contradicts the historical pattern where network congestion and fee spikes accompanied Bitcoin’s bull runs. Fees have been lower than a pregnant ant’s stomach! […]
What Is A Chain Rollback?

Ah, the good old blockchain, a buzzword that has been bastardised to death since the launch of altcoins. Bitcoin, like many altcoins, runs on top of a distributed ledger, hosted, verified and updated by a globally distributed network of nodes. This process of global record-keeping commonly refers to a blockchain; the purpose of this chain […]
What Is The Sequentia Side Chain?

Bitcoin is optimised for security and reliability. Its design, while robust, has inherent limitations when it comes to scalability. The blockchain, the underlying technology, can only process a finite number of transactions per second. This limitation, often referred to as the “scalability trilemma,” presents a significant challenge as the network’s popularity grows. As Bitcoin’s user […]
What Is Fractal Bitcoin?

It feels like nearly a lifetime ago now that Ordinals were making headlines and stirring up all sorts of arguments about how to use block space; while the debates raged on for a brief moment in time, fees were astronomically high, making the base chain unusable for the average person. If you wanted to spend […]
