In the crypto world, Jack Dorsey’s name has long transcended the label of "Twitter co-founder." He is a more steadfast advocate of crypto-punk than Coinbase founder Armstrong, with his investment in Bitcoin lasting for at least a decade, often prioritizing investment over profit.
This low-key technology prophet not only strongly advocates for Twitter to support Bitcoin Lightning Network payments but also recently launched Bitchat, a decentralized communication application that is completely based on Bluetooth Mesh network, combating censorship at the physical layer and upholding free speech.
01 Trinity, the three rebirths of Bitcoin
Jack Dorsey’s decentralized journey profoundly reflects the inheritance and innovation of the Bitcoin philosophy. He keenly realized that while Bitcoin’s value storage function exceeds practical applications, its underlying philosophy can give rise to more possibilities.
In 2019, based on 比特币 The OP_RETURN opcode gave birth to the first free Bitcoin on-chain social tool, Bitchat. It is similar to the inscription method, writing information into the transaction’s note, equivalent to "sneaking on the network to send messages."
In 2022, based on the low fee characteristics of BSV, a true on-chain social product called Bitchat emerged, where messages are sent through on-chain channels and paid for usage.
By 2025, Jack Dorsey, drawing on the ideas of the above two, will launch Bitchat, based on a local Bluetooth Mesh network, using a hardware support + free use model. It can run completely offline, achieving full decentralization and censorship resistance.
02 Bluetooth Mesh, a new paradigm of Decentralization communication
The new generation of Bitchat launched by Jack Dorsey is not just a chat application, but a communication experiment against internet censorship and centralized control. It returns to the original理念 of the internet while integrating the latest technology.
The core features of Bitchat include four aspects:
- Offline communication: Completely based on local Bluetooth Mesh network storage and message transmission, it can work without any network signal, which is also the ideal working environment for Bitchat;
- Anonymity: Extremely lightweight, no permanent account system or data persistence system is designed, can only be used as a chat room;
- Completely free: Purchasing Bluetooth Mesh hardware is the only expense, and now everyone has a mobile phone, basically no extra payment is required;
- IRC Style: Returning to the group chat model of the Web 1.0 era, extremely simple, focusing on text communication.
03 Privacy protection, financial-grade encryption safeguards freedom
In terms of privacy protection, Bitchat uncompromisingly applies cutting-edge technology from the field of cryptography. This is undoubtedly an important lesson that Jack Dorsey learned from Bitcoin – when it comes to privacy and security issues, "having is better than not having."
Both individual and group modes are designed with encryption. The group mode uses Argon2id to resist potential side-channel attacks. This algorithm is more commonly used by high-security level clients in finance, military, etc., making it somewhat "overkill" for group protection.
04 Market Boom, Crypto Ecosystem Thrives
As Jack Dorsey continues to promote the idea of Decentralization, the crypto market also迎来了 a new wave of excitement in September 2025. BTC突破 116,000 USDT, setting a new historical high.
Ethereum also performed well, with its price rising above $4,580 and testing the resistance level of $4,680. BNB once reached a historical high of $995.44, with a market capitalization surpassing $138.4 billion.
Market sentiment is generally optimistic, as the Federal Reserve’s September meeting confirmed a 25 basis point rate cut, providing more liquidity expectations for the entire crypto market.
05 Decentralization future, the perfect combination of Mesh and Nostr
Jack Dorsey’s vision goes far beyond the existing Bitchat app. In his conception, the combination of Mesh local networking and Nostr global networking will create a truly hardware-based, censorship-resistant social tool.
The future Bitchat plan will support more networking methods, including WIFI, LoRa, and even ultrasonic. These technologies will play a significant role in extreme scenarios such as disaster relief, allowing mobile phones to become text intercoms even without internet access.
Dorsey’s investment in the Bitcoin ecosystem far exceeds what most people can imagine. He not only launched the LDK development kit to support the Bitcoin Lighting Network but also strongly advocated for Twitter to support the payment functionality of the Lighting Network, keeping an eye on all possible developments of Bitcoin.
06 Crypto Market Panorama, Diverse Ecosystem Growing Together
While Jack Dorsey leads the wave of Decentralization, the entire cryptocurrency market is also showing a trend of diversified development.
XRP Strongly holding the $3.00 mark, the market is focused on whether it can challenge the $5.00 threshold in September. Cardano (ADA) is trading around $0.876 and needs to hold the support range of $0.87-$0.85 to maintain a bullish outlook.
Polkadot (DOT) has recently performed well, rising by 2.31% to reach $4.25. With the launch of Polkadot 2.0, its future development is worth paying attention to.
07 Innovation continues, Dorsey’s journey is still ongoing.
Jack Dorsey’s journey towards Decentralization proves that he is not just an entrepreneur, but also a staunch believer in the ideals of a cryptopunk. His projects may not be well-received by the users of this era, but they are full of creativity and foresight.
After achieving financial freedom, Jack Dorsey chose a purer way of life - pursuing free social interaction and decentralized networking methods, a commitment that has lasted for more than ten years.
From Bitcoin Lightning Network to Bluetooth Mesh, from BlueSky to Bitchat, Jack Dorsey has been exploring the next generation of social product forms, trying to build truly censorship-resistant communication tools.
