Bitcoin Needs Layer 2s to Scale, Says Goat Network

AMA recap highlights how L2s can boost Bitcoin’s sustainability and miner revenue

Bitcoin’s future depends on scaling solutions beyond its base layer. That was the central message from Kevin Liu, co-founder and CEO of Goat Network, during a recent AMA session held after Korea Blockchain Week. Liu emphasized that Bitcoin Layer 2s (L2s) are essential for expanding use cases, increasing miner revenue, and ensuring long-term sustainability.

Why scaling Bitcoin matters

Goat Network’s journey began in early 2023 with research into zero-knowledge computation. By late 2024, the team launched a zkVM capable of proving blocks in real time, a major step forward for Bitcoin’s limited Script language.

“We’re scaling Bitcoin natively, inheriting its security so holders keep control of their keys,” Liu explained. Goat Network’s approach anchors offchain computation to Bitcoin using BitVM2, turning complex processes into proofs while maintaining decentralization.

Building an ecosystem for Bitcoin

The project has evolved into a full ecosystem built around trade, yield, and play. Its offerings include:

• Safebox self-custody deposits for conservative users
• Yield products with varying risk profiles
• BTC-denominated games such as GOATRocket and SatoshiGOAT

“We offer trade, yield, and play so people can safely make their Bitcoin work,” Liu noted. Unlike many platforms, Goat does not rely on side tokens. Instead, decentralized sequencers process transactions, earn BTC gas fees, and return them to stakers.

Security through BitVM2

Security remains at the core. BitVM2 uses a challenge-based verification model where dishonest actors can be penalized, while honest users always keep access to funds. Liu stressed: “You don’t verify everything, only when there’s a challenge – with slashing to keep actors honest.”

For miners, the economic argument is critical. Currently, transaction fees make up just 1–2% of miner revenue, far below the healthier 10–20% target needed as block rewards decline. L2 solutions, Liu argued, will expand transaction volume and feed more fees back to the base layer.

“L2s are good for the whole ecosystem. More users and more activity on L2 mean more revenue for miners as well,” he said.

For skeptics, Liu’s advice is simple: start small, test with a fraction of Bitcoin, and explore. As halving events reduce block rewards, Bitcoin-native L2s may be the key to securing the network’s long-term future while keeping its decentralized foundation intact.
