Where Balance Meets Liberty
LibraChain is a next-generation, gasless Layer 1 blockchain built on a fork of Ethereum’s Dencun upgrade and enhanced with mesh networking technology for superior scalability and resilience. Its architecture has been purpose- engineered to remove the biggest barriers to Web3 adoption: gas complexity, onboarding friction, and limited interoperability.
By introducing a dual-token model
LibraChain allows users to interact with decentralized applications without holding any tokens beforehand , creating a Web2-like user experience while preserving the decentralization, security, and composability that define blockchain technology.
Validator onboarding is streamlined through one-click setup , reducing the technical barrier for network participation and promoting a healthy, globally distributed validator set. Adaptive block gas limits and the efficiency benefits of Dencun’s EIP-4844 blob transactions provide the throughput and cost efficiency required for large-scale adoption.
LibraChain’s omnichain interoperability framework ensures frictionless asset and data movement across leading Layer 1 and Layer 2 networks, positioning it as a central hub for cross-chain DeFi, gaming, RWA tokenization, and enterprise blockchain applications
In short, LibraChain combines the proven stability of Ethereum’s architecture with innovations in gas abstraction, scalability, and interoperability , paving the way for mass Web3 adoption at both consumer and enterprise levels.
Gasless Execution with Internal GAS Balances
Unlike Ethereum, where EOAs must hold ETH to cover gas fees, LibraChain introduces an internal GAS token system for fee abstraction:
In Ethereum, the need to pay upfront gas fees poses onboarding friction — especially for new users unfamiliar with wallets, seed phrases, or exchange flows
In contrast, LibraChain accounts are designed with usability-first principles : GAS token system for fee abstraction:
Smart Contract and Storage
Contract accounts in LibraChain behave identically to Ethereum’s, with full support for:
Contracts can observe , but not manipulate, the GAS abstraction layer — ensuring separation of concerns and resistance to exploitation.
In LibraChain, the execution model builds directly on Ethereum’s architecture but extends it through gas abstraction and EIP-4844 blob integration.
LibraChain supports two core interaction types: transactions and messages. Both are mechanisms for transferring value, invoking contracts, or triggering computations, but differ in origin and processing context.
Transactions
A transaction in LibraChain is a signed data package originating from an externally owned account (EOA) . It is broadcasted to the network and includes the following fields:
Unlike Ethereum, the user pays no fees. Gas costs are internally managed using the GAS token, a non-tradable technical token minted per block and allocated to users as needed. From a user perspective, transactions are free, while internally, the EVM still meters and tracks gas for consistency and resource control.
Blob Transactions (EIP-4844)
With Dencun integration, LibraChain supports blob-carrying transactions introduced in EIP-4844 (Proto-Danksharding) . These enable temporary, low- cost storage of large data payloads — ideal for rollups and L2s.
Key attributes of blob tx:
This significantly reduces rollup data costs and improves scalability.
A message is an internal call between contracts, never serialized or sent over the network. It includes:
Messages are created when a contract uses the{" "} {" "} CALL, DELEGATECALL, STATICCALL , or CREATE opcode.
Just like transactions, message calls in LibraChain benefit from:
Execution Tree Example
If EOA Alice sends a transaction with a 100,000 gas limit to Contract A, and A uses 40,000 gas before calling Contract B with 30,000 gas, then:
All of this is internally covered by the GAS allocation — the user (Alice) pays nothing.
Summary
LibraChain maintains full EVM support while improving the transaction and contract interaction model through:
Preliminaries
Account model matches Ethereum (EOAs & contracts). Consensus is Proof of
Stake (Prysm client). EVM gas metering is preserved, but end‑users never pay
fees: gas is covered by an internal, non‑tradable GAS token minted per block
and allocated dynamically. Dencun (EIP‑4844) blob‑carrying transactions are
supported with a separate data‑gas market; blobs are retained for ~18 days.
Transaction fields (execution‑relevant)
to (recipient; absent ⇒ contract creation); value (LIB); data (call data /
init code); nonce; gasLimit; signature; optional blobVersionedHashes[] with
data‑gas variables; EIP‑1559 fields are accepted for compatibility but
effective user gas price is 0 on LibraChain.
Algorithm (LibraChain)
Safety property
As in Ethereum, if A calls B with G gas, A can lose at most G gas. Child
reverts revert their own sub‑state unless bubbled up; parent execution need
not revert.
Worked example (gasless)
Tx: value=10 LIB, gasLimit=2000, data=64 bytes, no blobs. Validate
sig/nonce; allocate internal GAS; transfer 10 LIB to contract; contract
writes storage slot[2] = CHARLIE using 187 gas; commit state; user pays 0;
gasUsed recorded for validator LIB rewards; no user refund step exists.
Dencun / blobs note
For blob‑carrying txs: validate versioned hashes, account data‑gas in the
blob market, respect block data‑gas limits; blobs are stored off‑EL with
~18‑day retention; contracts reference them but cannot read bytes directly
from EL.

Code Execution in LibraChain
The code in LibraChain smart contracts is written in Ethereum Virtual Machine (EVM) bytecode — a low-level, stack-based instruction set inherited from Ethereum. LibraChain preserves full EVM compatibility , ensuring that contracts developed for Ethereum or other EVM-based chains execute identically.
A contract’s code is a series of bytes, where each byte corresponds to an opcode . Code execution generally follows an instruction fetch–execute cycle :
Execution Data Spaces
Contracts have access to three distinct storage areas during execution
Additional Accessible Context
During execution, contracts can access:
Execution Model in LibraChain (Gasless Context)
In Ethereum, execution consumes gas charged to the sender at a GASPRICE. In LibraChain
Dencun Upgrade Impacts on Execution
LibraChain integrates all execution-layer improvements from Ethereum’s Cancun fork:
Formal Execution State
At any point, the EVM’s full computational state in LibraChain can be
represented by:
block_state, transaction, message, code, memory, stack, pc, gas)

Example Operations
Implementation Notes
While highly optimized JIT compilers and EVM interpreters exist, a basic EVM implementation can be achieved in a few hundred lines of code. LibraChain’s execution layer can integrate the same optimizations as Ethereum clients while preserving gasless semantics at the protocol level.
Block Validation and Architecture in LibraChain
The LibraChain blockchain shares many architectural similarities with Ethereum, but incorporates several key differences aligned with its gasless transaction model, Proof-of-Stake (PoS) consensus, and Dencun upgrade enhancements.
Key Differences from Ethereum
Block Structure
Each LibraChain block contains:
Unlike Bitcoin, where blocks store only transactions, LibraChain (like Ethereum) stores both the transactions and the post-state root.
Block Validation Algorithm in LibraChain
The block validation process, adapted for LibraChain’s PoS and gasless model, is as follows:
State Storage Model
LibraChain uses Ethereum’s modified Merkle Patricia Tree (MPT) to store account and contract state.
Code Execution Location
Contract code execution is performed during block validation by every validator node . If a transaction is included in block B, the contract execution it triggers will be re- executed by all nodes that download and validate block B, both now and in the future. This ensures deterministic consensus across the network
LibraChain is designed as a next-generation execution layer for decentralized applications (DApps), with a focus on removing the onboarding and usability friction that has historically limited mainstream adoption of blockchain technology.
In traditional EVM-based environments, users must hold native tokens to pay transaction fees, navigate complex wallet setup processes, and manage gas price selection. LibraChain eliminates these barriers through its gasless transaction model , powered by the internal GAS token. This approach allows end-users to interact with DApps without ever holding LIB or any other cryptocurrency, while still maintaining EVM compatibility and execution determinism
Key Advantages for Developers and Users
Potential Application Domains

LibraChain’s EVM compatibility means existing Ethereum smart contracts can be deployed with minimal changes. Developers gain access to:
By combining zero gas onboarding, EIP-4844 scalability , and full EVM compatibility , LibraChain provides a unique execution environment optimized for the next billion blockchain users
LibraChain operates on a dual-token architecture designed to optimize both network efficiency and ecosystem value creation :
This model ensures technical scalability through GAS while enabling economic sustainability and community empowerment through LIB.
Consensus Mechanism — Proof of Stake (PoS) via Prysm Beacon Chain LibraChain employs a Proof of Stake consensus protocol powered by the Prysm Beacon Chain , ensuring high throughput, energy efficiency, and rapid finality. Validators are responsible for proposing and attesting to blocks, securing the network through stake-based economic incentives. Finality is achieved within seconds, minimizing the risk of chain reorganizations and providing a robust security framework suitable for enterprise-grade and consumer-facing applications.
Validator onboarding is streamlined through one-click setup , removing the technical barriers that traditionally hinder participation. The network’s mesh technology further enhances decentralization by enabling efficient peer-to-peer propagation of blocks and attestations, optimizing performance even at scale
Governance — LIB Token Holder Voting
LibraChain implements an
on-chain governance system
that empowers LIB token holders to actively shape the future of the
protocol. Governance proposals may include:
Voting power is proportional to the amount of LIB staked, aligning the decision- making process with stakeholders’ vested interest in the long-term security and growth of the network. Governance execution is transparent, verifiable on-chain, and finalized through smart contract–enforced rules to prevent arbitrary changes.
Core Principles of LibraChain Governance
Base Architecture — Ethereum Dencun (Deneb) Fork LibraChain is built as a Layer 1 blockchain forked from Ethereum’s Dencun (Deneb) upgrade , inheriting the latest protocol optimizations including EIP-4844 proto-danksharding , blob transactions, and reduced calldata costs. This foundation ensures native compatibility with the Ethereum Virtual Machine (EVM) and seamless deployment of existing Ethereum-based smart contracts.

LibraChain implements
adaptive block gas limit scaling
that dynamically increases by up to 10% under network load. This allows:
Mesh Networking Technology
LibraChain integrates a mesh-based peer-to-peer propagation layer
that enhances scalability, resilience, and redundancy. Mesh networking
enables faster block and attestation dissemination across geographically
distributed validators, ensuring high network efficiency and uptime even
under adverse conditions.
Key Technical Advantages
