Introduction​

Since the release of Bitcoin in 2008, it has revolutionized the financial world with its concept of a "peer-to-peer electronic cash system," as outlined in its whitepaper. Bitcoin's unshakable security and global consensus quickly made it a core asset in the cryptocurrency space. Thousands of miners secure the Bitcoin network through competitive mining, while Bitcoin itself has become a major asset on exchanges worldwide, attracting a significant user base. Bitcoin's global influence and solid consensus foundation have established it as a store of value, with the potential to become a global currency.

During EDCON 2024, the chief contributor to the NOTE protocol, Japan's blockchain technology company ChainBow, released a new interaction protocol between Bitcoin and dApps called Bitcoin Action, and demonstrated interactions between wallets and dApps.

Since its inception, Bitcoin has undergone countless technological innovations. The emergence of the NOTE Protocol marks a significant milestone in Bitcoin's history. After six months of meticulous protocol and ecosystem development, the NOTE Protocol is now officially available to the global audience. Our vision aligns with Bitcoin's: to provide a peer-to-peer digital currency for 6 billion people worldwide.

If we say the native Bitcoin scripting language is Turing complete, many people will criticize us.

Turing Completeness refers to a programming language that can implement any computation a Turing machine is capable of. This concept comes from Alan Turing, who proposed the Turing Machine model. It’s an abstract machine that performs calculations by reading and writing symbols on an infinitely long tape.

Since the public release of its Proof of Concept indexer in February 2024, the NOTE protocol has garnered widespread attention. Following feedback and demands from users, the protocol has been continuously upgraded.

As of April 4th, the following upgrades have been implemented:

NOTE: The Bitcoin Protocol with Smart Contract Capabilities​

The NOTE protocol marks a significant advancement in the history of Bitcoin.

The NOTE protocol is a digital asset issuance protocol based on Bitcoin's UTXO model, distinct from many recently emerged protocols, as NOTE is genuinely rooted in Bitcoin's UTXO model. It utilizes a smart contract language compatible with Typescript, whose compilation results in Bitcoin native opcodes, enabling a powerful feature set that includes Oracles and zero-knowledge proofs.

🚀 Exciting update from our team: We’ve crafted a #Bitcoin protocol, tailored for #UTXO-based blockchains. This protocol not only allows for the creation of tokens and NFTs but also integrates optional data #encryption, #SmartContracts, and #DID definitions, all under the MIT License.
