TBC (TuringBitChain) is a blockchain project developed as a hard fork of Bitcoin, designed to deliver scalable, secure, and cost-efficient peer-to-peer digital transactions. Built on Proof of Work consensus and the UTXO model, TBC focuses on supporting large-scale payment activity and on-chain applications while maintaining decentralisation and transparent verification.
As blockchain adoption expands beyond early experimentation into real-world financial use cases, limitations such as network congestion, elevated transaction fees, and constrained throughput continue to restrict usability across many networks. TBC positions itself as an infrastructure-focused blockchain designed to address these challenges through architectural enhancements aligned with Bitcoin’s original payment-oriented intent.
In the Bitcoin whitepaper published in 2008, Satoshi Nakamoto stated:
“A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution.”
TBC frames its development around this principle by prioritising scalable on-chain capacity, efficient transaction processing, and predictable transaction costs.
Proof of Work Security and Network Integrity
Security remains a foundational element of TBC’s design. The network operates on Proof of Work consensus, preserving Bitcoin’s established security assumptions and decentralised validation model while supporting a distributed ecosystem of miners and nodes.
Satoshi Nakamoto addressed transparency and privacy trade-offs within blockchain systems, noting:
“The system is designed to protect user privacy, but not absolutely. Every transaction is broadcast on the network.”
He also commented on energy expenditure within Proof of Work systems:
“The utility of the exchanges made possible by Bitcoin will far exceed the cost of electricity used. Therefore, not having Bitcoin would be the net waste.”
TBC reflects this philosophy by treating Proof of Work as a necessary security investment. The network introduces efficiency-focused infrastructure optimisations intended to improve scalability and node accessibility while maintaining verifiable and transparent on-chain data. Techniques such as dynamic data pruning are designed to reduce storage overhead for lightweight nodes under typical operating conditions.
Low Transaction Costs and Practical Payment Utility
Payment usability is a central commercial objective for TBC. High transaction fees and congestion have limited blockchain suitability for everyday transfers, microtransactions, and remittances across many networks.
Satoshi Nakamoto cautioned against excessive defensive mechanisms that undermine legitimate use, stating:
“We have to make the barrier high enough to prevent spamming, but low enough to still allow legitimate use.”
TBC addresses this challenge by expanding block capacity and optimising transaction validation. The network is designed to support high transaction volumes while maintaining verification efficiency, enabling transaction costs that are designed to remain low under typical network conditions. This approach supports use cases requiring frequent transfers, predictable fees, and payment scalability.
Throughput and On-Chain Scalability
Scalability remains a critical requirement for blockchain networks seeking broad adoption. In 2010, Satoshi Nakamoto observed:
“I’m sure that in 20 years there will either be very large transaction volume or no volume.”
TBC responds to this challenge through a large block architecture intended to support higher transaction throughput compared to traditional Bitcoin-based implementations. By leveraging parallel UTXO validation and optimised block processing, the network is designed to handle sustained transaction growth directly on chain, reducing reliance on layered scaling solutions.
This scalability supports payment processing, data-intensive applications, and blockchain use cases often associated with enterprise and large-scale deployments.
UTXO-Based Smart Contracts and On-Chain Applications
Although Bitcoin was not originally positioned as a smart contract platform, Satoshi Nakamoto highlighted the extensibility of its scripting system, stating:
“The scripting language is designed to be flexible and extensible… advanced features such as multi-signature transactions, time locks, and more complex logic to be added in the future.”
Building on this foundation, TBC introduces a UTXO-based smart contract framework designed to enable advanced on-chain logic while preserving Bitcoin’s transaction architecture. Smart contracts execute independently at the transaction output level, reducing global state congestion and improving execution efficiency.
The network supports decentralised applications, on-chain token standards, and digital assets, with full data storage maintained on chain to enhance transparency, auditability, and long-term data integrity.
Conclusion
Bitcoin was introduced as an open experiment. In his final communications, Satoshi Nakamoto wrote:
“ Bitcoin is an experiment. Let’s see how it plays out.”
He also stated:
“If you don’t believe me or don’t get it, I don’t have time to try to convince you, sorry.”
TBC positions itself as part of this ongoing experiment, extending Bitcoin’s original payment-focused vision through modern scalability, cost-efficient transactions, and expanded on-chain functionality. By combining Proof of Work security, large block throughput, and UTXO-based programmability, TBC presents a blockchain infrastructure designed for real-world adoption and sustained transaction volume.
