Frequently asked questions

What does scalability mean for Bitcoin?

Scalability refers to Bitcoin’s ability to handle growing transaction volumes quickly and at low cost. Bitcoin processes just 3 to 7 tps, far below what mainstream payment systems require.

Why can’t Bitcoin just increase its block size?

Larger blocks increase throughput but make it harder for regular users to run full nodes, pushing the network toward centralization. Bigger blocks risk decentralization, which undermines Bitcoin’s core security model.

What are Layer 2 solutions, and how do they help Bitcoin scale?

Layer 2 solutions process transactions off-chain and settle them on Bitcoin’s main blockchain only when needed, enabling fast and cheap transfers. Lightning Network offers rapid, low-cost transactions without changing the base protocol rules.

How have scalability limits affected Bitcoin adoption?

Fee spikes and slow confirmations during high-demand periods have frustrated users and dampened media sentiment around Bitcoin’s growth potential. Scalability bottlenecks caused delays that negatively affected adoption and network engagement metrics.
