Unleashing the Potential of nBTC EVM: A Paradigm Shift in Blockchain Technology

Embrace the future of blockchain with the nBTC EVM. #BeyondMonolithic #EveryComputationMatters

In the pursuit of enhancing EVM performance, numerous approaches are poised for implementation. However, many risk breaking Ethereum protocol's backward compatibility and disrupting a plethora of dApps. This calls for a fresh start.

Execution layers perched atop Ethereum present an unprecedented opportunity to craft something extraordinary. Designs no longer need to adhere to backward compatibility, offering a clear path towards global throughput and adoption.

Much like the evolution from x86 to ARM in CPU architecture, we envision the nbtcVM in a similar transformative light.

Continued reliance on the EVM as a foundational or secondary layer will lead to costly and restrictive design spaces for blockchain applications, limiting global accessibility. This constrains DeFi projects and stunts growth.

Apps will inevitably seek better alternatives to Ethereum & EVM as global demand escalates and computational resources become scarcer.

In many ways, the nbtcVM can be seen as an evolved iteration of the EVM, incorporating the most robust ideas from over the years, along with insights from WASM, Bitcoin, and other influential blockchain runtimes.

For starters, the nbtcVM utilizes 64-bit words, as opposed to 256-bit. This optimized word size empowers libraries at the application level to efficiently handle large numbers.

The nbtcVM employs a register-based system, rather than a stack-based one. This optimization reduces the overhead of every operation, leading to significant cost savings.

The nbtcVM introduces a new memory architecture that eliminates wasteful serialization during contract calls. This significantly enhances cross-contract communication.

With nBTC, calling between contracts is as effortless as passing pointers to data, thanks to the shared memory block accessible by all call frames.

The nbtcVM prioritizes fraud-provability from its inception, selecting operations with this property in mind.

In contrast to Ethereum's singular native asset, Ether, nBTC supports multiple native assets. Contracts can mint their UTXO-based native assets, reaping the benefits of native-level call and optimization.

The nbtcVM streamlines resource-constrained systems with ops like dynamic length memcopy, memequal, and memclear, reducing operational costs.

A form of pay to script hash, inherited from Bitcoin, predicates in the nbtcVM enable functionalities like multi-sigs without the need for a contract.

The nbtcVM eliminates the necessity for approve/transfer from UX with scripts, simplifying actions from an origin sender without deploying a contract.

Built on an atomic UTXO paradigm from the start, nBTC offers a more efficient system of asset transfer and ownership, bypassing the need to rebuild the accounts tree for every transaction.

The nbtcVM's ops are designed with auditing edge-cases in mind, ensuring predictable outcomes for each opcode.

Facilitating multi-witness, multi-input, multi-output transactions, nBTC empowers developers with unprecedented options at the transaction level.

nBTC features a multi-witness, multi-input, multi-output transactional design, eliminating the need for complex multi-send contracts.

The nbtcVM enables different sig-hash states, allowing for meta-transactions and partially signed transactions by multiple parties.

For enhanced introspection, the nbtcVM provides the entire transaction in memory, crucial for predicate spending conditions.

The nbtcVM arrives equipped with safe-math at the VM level, enabling flexible activation and deactivation.

All nbtcVM operations are 32-bit word aligned, simplifying parsing for efficient execution and auditability.

Designed for seamless integration with tooling, the nbtcVM is accompanied by its companion language @BitLang, ensuring accessibility and efficiency.

Incorporating Ethereum's keccak256 operation, the nbtcVM supports backward compatibility for hashing and signing.

The nbtcVM paves the way for an efficient, portable, fraud-proof, and accessible blockchain virtual machine, essential for realizing the autonomous future.

BitLang seamlessly caters to both Solidity and Rust developers, ensuring a smooth transition into this groundbreaking technology.
