Avalanche has long been a pioneer in horizontal blockchain scalability through its innovative subnet architecture—now rebranded as Avalanche Layer 1 (L1). These sovereign, application-specific blockchains offer customizable infrastructure tailored to diverse use cases, attracting both crypto-native builders and institutional players like Konami and Intain.
However, despite its technological promise, the existing validation requirements for Avalanche L1s have posed significant barriers to entry—particularly due to high operational costs and a mandatory 2,000 AVAX staking requirement tied to mainnet validation.
Enter ACP-77, a transformative community proposal designed to unlock the full potential of Avalanche L1s by redefining their relationship with the core network. This article explores how ACP-77 reshapes validation dynamics, enhances sovereignty, introduces sustainable economic models, and ultimately democratizes access across the Avalanche ecosystem.
What Is ACP-77?
ACP-77 is a governance proposal that fundamentally overhauls how Avalanche L1s are created, managed, and validated. At its core, it decouples Avalanche L1 validators from the obligation to validate the primary Avalanche mainnet—unlocking greater flexibility, reducing costs, and enabling regulatory alignment for enterprise-grade deployments.
This shift marks a pivotal evolution in Avalanche’s architecture, moving toward a more modular, scalable, and economically sustainable model where each L1 operates with increased autonomy.

Enhanced Sovereignty for Avalanche L1s
One of the most impactful changes introduced by ACP-77 is the sovereign independence granted to Avalanche L1 validators.
Under the current system, any validator participating in an Avalanche L1 must also validate the entire mainnet—including the Contract Chain (C-Chain), Platform Chain (P-Chain), and Exchange Chain (X-Chain). This dual responsibility demands substantial hardware resources (minimum 8 vCPUs, 16 GB RAM, 1 TB storage) and a non-negotiable 2,000 AVAX stake, equivalent to over $40,000 at current market rates.
ACP-77 eliminates this requirement. Instead of full mainnet validation, L1 validators will only need to sync with the P-Chain, which tracks validator set changes and facilitates cross-L1 communication via Avalanche Warp Messaging (AWM).
Why Sovereignty Matters
This architectural refinement delivers several critical benefits:
- Lower Entry Barriers: Removing the need for high-end infrastructure and large AVAX stakes opens participation to a broader range of individuals and organizations.
- Regulatory Flexibility: Institutions can now run permissioned L1s without being forced to validate the public, permissionless mainnet—avoiding exposure to potentially non-compliant transactions.
- Custom Validation Rules: Each Avalanche L1 gains the authority to define its own staking mechanisms, validator criteria, and reward distribution—shifting control from the P-Chain back to the individual L1.
This transition represents a major milestone in Avalanche’s vision of supporting multiple sovereign blockchains operating in parallel—each optimized for specific industries, compliance needs, or performance goals.
Introducing Dynamic Fees for Sustainable Economics
With the removal of the 2,000 AVAX staking requirement, a new mechanism was needed to ensure long-term economic sustainability and prevent spam or resource overuse on the P-Chain. ACP-77 answers this challenge with a dynamic fee model.
How Dynamic Fees Work
Instead of fixed transaction fees, Avalanche L1 validators will pay ongoing, variable fees to maintain their presence on the P-Chain. These fees are used to store essential metadata—such as IP addresses, BLS public keys, and uptime tracking—for cross-chain communication and validator coordination.
The fee amount adjusts dynamically based on network utilization:
- When the total number of active Avalanche L1 validators exceeds a target threshold, fees increase.
- During periods of lower activity, fees decrease accordingly.
This adaptive pricing model aligns with real-time demand and ensures fair compensation for the P-Chain’s role in enabling secure inter-L1 messaging and validator management.
Operational Implications
Validators will need to periodically replenish their P-Chain balance to remain active—similar to maintaining gas fees on other networks. While this introduces recurring costs, it significantly reduces upfront capital requirements, making it feasible for smaller teams and independent operators to participate.
This shift from capital-intensive staking to usage-based payment fosters a more inclusive and resilient validator ecosystem.

Benefits Across Stakeholder Groups
ACP-77 is not just a technical upgrade—it's a strategic enabler that benefits multiple segments within the Avalanche ecosystem.
For Institutions
Enterprises and regulated entities can now deploy compliant, permissioned Avalanche L1s without being entangled in public chain validation. This separation supports adherence to financial regulations (e.g., KYC/AML frameworks) while still leveraging Avalanche’s high-performance consensus engine.
Use cases include:
- Tokenized asset platforms
- Private enterprise blockchains
- Regulated NFT marketplaces
For Retail Builders and DAOs
Independent developers, DAOs, and community-driven projects benefit from reduced operational overhead. The lower barrier to entry encourages experimentation and innovation—fueling organic growth in decentralized applications across gaming, DeFi, social media, and more.
Additionally, greater validator decentralization improves network resilience and censorship resistance—key tenets of Web3.
The Road Ahead: Scaling a Multi-Layer Future
ACP-77 builds upon previous upgrades like Banff (which enabled cross-subnet messaging via AWM) and Evergreen (which introduced privacy-preserving features for enterprise L1s). Together, these innovations form a cohesive roadmap toward a truly scalable and interoperable blockchain ecosystem.
By empowering each Avalanche L1 with sovereignty and flexible economics, ACP-77 lays the foundation for:
- Thousands of specialized blockchains operating in parallel
- Faster time-to-market for new projects
- Improved regulatory clarity for institutional adoption
- Greater decentralization across the validator landscape
As Avalanche continues to evolve, ACP-77 stands as a cornerstone upgrade—one that unlocks both technical potential and real-world applicability.
Frequently Asked Questions (FAQ)
Q: What does ACP-77 stand for?
A: ACP stands for Avalanche Community Proposal. ACP-77 is a specific governance initiative aimed at transforming how Avalanche Layer 1 blockchains are validated and managed.
Q: Do I still need to stake AVAX under ACP-77?
A: No longer mandatory at the mainnet level. While individual Avalanche L1s may impose their own staking rules, the requirement to stake 2,000 AVAX for mainnet validation is removed under ACP-77.
Q: How does ACP-77 improve scalability?
A: By decoupling L1 validation from mainnet duties and introducing dynamic fees, ACP-77 reduces resource strain and allows more chains to operate efficiently without compromising security or performance.
Q: Can any project launch an Avalanche L1 after ACP-77?
A: Yes. The lowered barriers make it easier for both institutional and retail developers to launch customized L1s tailored to their application needs.
Q: What happens if an L1 validator fails to pay dynamic fees?
A: Their registration on the P-Chain will expire, temporarily removing them from the validator set until fees are restored. This ensures only committed participants maintain network integrity.
Q: Is ACP-77 live on mainnet yet?
A: As of early 2025, ACP-77 is under community review and testing. Final deployment depends on governance voting outcomes and network readiness assessments.
