Release Date: January 2026 Based on: go-ethereum v1.15 + v1.16 stability patches
Audit Report Attached
Overview
Go-MemeCore v1.15.1 is a major upgrade that implements key EIPs from Ethereum's Dencun (Deneb+Cancun) and Pectra (Prague+Electra) hardforks, optimized for the PoSA (Proof of Stake Authority) based PoM (Proof of Meme) consensus algorithm.
Since Gmeme integrates the consensus layer, execution layer, and data layer into a single unified architecture, the consensus-only hardforks (Deneb, Electra) are excluded. Only the Cancun and Prague upgrades are applied, which we have named CanPraTree (Cancun + Prague).
This upgrade enables:
- Dramatically reduced gas fees through the GasTree hardfork
- Account Abstraction support via EIP-7702 for next-generation DApp UX
- L2 rollup integration aligned with Ethereum's Rollup-Centric roadmap
- Seamless migration of Ethereum ecosystem DApps to MemeCore
Highlights
GasTree Hardfork
- Reduces gas prices to 1/100 of previous levels (from 1500 gwei to 15 gwei), dramatically lowering transaction costs and improving user accessibility.
CanPraTree (Dencun + Pectra) Hardfork
The core features are EIP-4844 and EIP-7702:
- EIP-4844 (Cancun): Proto-Danksharding with Blob Sidecar Storage integrated in a single-layer architecture (no Beacon chain required), enabling Blob transactions and L2 chain integration.
- EIP-7702 (Prague): Account Abstraction support allowing EOAs (Externally Owned Accounts) to function like smart contracts.
Key Features
1. Ethereum Standard Compatibility
- Geth v1.15 base + v1.16 stability patches: Same codebase as Ethereum mainnet
- 9 EIPs implemented: 6 from Dencun (Cancun) + 3 from Pectra (Prague)
- KZG Cryptography: Uses identical trusted setup as Ethereum
2. Account Abstraction Support
EIP-7702 enables EOAs to function like smart contracts:
- Sponsored Transactions: Gas fee payment by third parties
- Batch Transactions: Multiple operations in a single TX
- Social Recovery: Account recovery through designated guardians
- Session Keys: Limited-permission temporary keys for DApps
3. Up to 90% L2 Rollup Cost Reduction
- EIP-4844 Proto-Danksharding allows L2 rollups to use Blobs instead of calldata
- Blob data is retained for ~18.2 days at significantly lower gas costs than calldata
4. L2 Ecosystem Ready
Gmeme chain now has complete technical foundation for integration with major L2 solutions (Arbitrum, Optimism, zkSync):
| Feature | L2 Integration Effect |
|---|---|
| EIP-4844 Blob TX | Data availability layer for Optimistic/ZK Rollups |
| EIP-2935 Block Hash | 8,191 block hash lookups for L2→L1 message verification |
| KZG Commitment | ZK Rollup validity proof verification support |
| Point Evaluation | Blob data integrity verification precompile |
Supported L2 Architectures:
- Optimistic Rollup (Arbitrum, Optimism style)
- ZK Rollup (zkSync, StarkNet style)
- Validium (off-chain DA + on-chain verification)
- Sovereign Rollup (independent execution + DA layer separation)
5. 32x Blockchain History Accessibility Improvement
- EIP-2935 expands queryable past block hashes from 256 to 8,191
- Significantly improves reliability of cross-chain bridges, oracles, and verification systems
6. Enhanced Smart Contract Developer Experience
- Transient Storage: Dramatically reduces reentrancy guard implementation costs
- MCOPY Opcode: Memory copy optimization for improved contract gas efficiency
Performance and Stability Improvements
Blob Storage Architecture Optimization
- Sidecar cache: 1024 BlobSidecars cache for improved query performance
- Auto-attach Blob Sidecar in GetBlock: Automatic inclusion of related Blob data
- writeKnownBlock improvement: Guaranteed Blob Sidecar storage for Cancun+ blocks
- Ancient DB integration: Efficient Blob data archiving
Transaction Pool Optimization
- Billy handler optimization for per-transaction Blob storage
- Authority tracking error log level reduced from Error to Trace
Tracer Improvements
- Fixed blockhash return in TraceCall with block n+1 override
- Panic prevention for nil block number override
- Added code hash to prestateTracer
- Added ERC-7562 tracer tests
PoSA Compatibility Optimization
PoSA-Specific Settings
- Optimized for PoSA consensus algorithm
- Removed unnecessary Consensus Layer related code
- AuthRPC disabled
- Removed unnecessary network settings
System Call Order Optimization
- EIP-7685 request processing disabled (unnecessary for PoSA)
Monitoring and Debugging Improvements
- Blob transaction count added to block import logs for improved observability
- BlobSidecars item added to DB Inspect
Applied EIPs Summary
Dencun (Cancun) Hardfork EIPs
| EIP | Description | Status |
|---|---|---|
| EIP-4844 | Blob Transactions (Proto-Danksharding) | Fully Supported |
| EIP-4788 | Parent Block Root | PoSA Compatible (EmptyRootHash fixed) |
| EIP-7516 | BLOBBASEFEE Opcode | Supported |
| EIP-1153 | Transient Storage (TLOAD, TSTORE) | Supported |
| EIP-5656 | MCOPY Opcode | Supported |
| EIP-6780 | SELFDESTRUCT Change | Supported |
Pectra (Prague) Hardfork EIPs
| EIP | Description | Status |
|---|---|---|
| EIP-7702 | EOA Account Code Delegation | Supported |
| EIP-2935 | Block Hash Storage in State | Supported |
| EIP-7623 | Calldata Cost Increase | Supported |
Disabled EIPs (Not Required for PoSA)
PoSA uses a system contract-based validator management system, so Ethereum PoS protocol-level validator management EIPs are not applied.
| EIP | Description | Reason for Disabling |
|---|---|---|
| EIP-6110 | On-chain Validator Deposits | For Ethereum PoS validator deposits. PoSA manages validators via ValidatorSet system contract |
| EIP-7002 | EL-triggered Withdrawals | For Ethereum PoS staking withdrawals. PoSA handles reward distribution via system contract |
| EIP-7251 | MAX_EFFECTIVE_BALANCE Increase | For Ethereum PoS validator balance cap. PoSA validator balances managed by contract |
| EIP-7685 | General Purpose EL Requests | For CL-EL request processing. PoSA uses single-layer architecture |
| EIP-2537 | BLS12-381 Curve Precompile | For Ethereum PoS BLS signature verification. PoSA uses ECDSA-based signatures |
