Bitcoin

Bitcoin is the first and most recognizable blockchain, created as a decentralized network for transferring value without intermediaries. It relies on Proof of Work with SHA-256, has a fixed supply of 21 million BTC, and remains one of the most secure public networks thanks to its enormous global mining base.

Although Bitcoin L1 is not designed for advanced smart contracts, a rich ecosystem has formed around it: Lightning Network for instant micropayments, sidechains and Layer 2 solutions such as Liquid, Rootstock, and Stacks, plus newer protocols like Ordinals and BRC-20. This opens the door to wallets, payment gateways, custody products, and even Bitcoin-based DeFi and NFT services.

If you plan to launch a payment service, crypto platform, or innovative product on Bitcoin and its surrounding ecosystem, FreeBlock can build it turnkey - from protocol architecture and integrations to user-facing interfaces.
