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 unparalleled customization for diverse use cases, from gaming to regulated financial services. However, high entry barriers have historically limited broader participation in Avalanche L1 validation. That’s where ACP-77, a transformative community proposal, comes into play.
This article explores how ACP-77 is reshaping the Avalanche ecosystem by decentralizing access, enhancing regulatory compliance, and enabling sustainable economic models—all while preserving the network's robust security and interoperability.
The Evolution of Avalanche L1
Avalanche L1s are independent blockchains operating within the Avalanche ecosystem. Unlike general-purpose chains, they are often tailored for specific applications or enterprise needs. This flexibility has attracted major players such as Konami, leveraging Avalanche L1 for its NFT platform, and Intain, using it for tokenizing real-world assets under strict compliance frameworks.
Over time, key upgrades have strengthened Avalanche L1 capabilities:
- Banff Upgrade: Introduced Avalanche Warp Messaging (AWM), enabling secure cross-chain communication between L1s.
- Evergreen Framework: Designed for enterprises requiring privacy and regulatory compliance on permissioned Avalanche L1s.
Despite these advancements, one persistent challenge remains: the high barrier to entry for validators.

Current Validator Requirements: A High Barrier
To become a validator on an Avalanche L1 today, participants must also validate the primary network—comprising the Contract Chain (C-Chain), Platform Chain (P-Chain), and Exchange Chain (X-Chain). This dual responsibility demands significant resources:
- Hardware: Minimum of 8 AWS vCPUs, 16 GB RAM, and 1 TB storage.
- Staking Requirement: At least 2,000 AVAX must be staked.
While 2,000 AVAX was once a manageable threshold, the token’s appreciation has made this cost prohibitive. At peak market value, it exceeded $250,000; even now, it represents over **$41,000** depending on current prices.
This high upfront cost centralizes validation power among well-capitalized entities, hindering decentralization and limiting ecosystem diversity. For institutions concerned with regulatory risk, being forced to validate an open, permissionless mainnet adds further complications.
Introducing ACP-77: A New Era for Avalanche L1
ACP-77 is a pivotal community-driven proposal designed to redefine how Avalanche L1s operate and interact with the core network. Its primary goal? To decentralize access, enhance sovereignty, and ensure long-term sustainability—without compromising security or interoperability.
Sovereignty: Full Control for Avalanche L1s
Under ACP-77, Avalanche L1 validators will no longer need to validate the main network. Instead, they’ll only need to sync with the P-Chain, which tracks validator set changes and facilitates cross-L1 communication via AWM.
This decoupling brings two major benefits:
- Lower Operational Costs: Validators can run leaner infrastructure focused solely on their L1.
- Regulatory Flexibility: Institutions can operate compliant, permissioned L1s without exposure to unregulated transactions on the public mainnet.
Moreover, each Avalanche L1 gains full authority over its own validation rules—including staking requirements, reward distribution, and node eligibility. The P-Chain will no longer manage or distribute staking rewards for individual L1s.
This shift marks a critical milestone: true sovereignty for Avalanche L1s, enabling a scalable ecosystem of independent yet interconnected blockchains.
Dynamic Fees: Sustainable Economics Without High Stakes
To maintain network integrity after removing the 2,000 AVAX staking requirement, ACP-77 introduces a dynamic fee model on the P-Chain.
Instead of fixed transaction fees, Avalanche L1 validators will pay ongoing, variable costs based on:
- The total number of active L1 validators
- Network utilization levels
- Resource load imposed on the P-Chain
Each validator consumes memory on the P-Chain by storing metadata such as IP addresses and BLS public keys. As more validators join, system load increases—so fees rise proportionally to manage demand and prevent spam.
Conversely, when usage drops below target thresholds, fees decrease to encourage participation.
This continuous payment mechanism ensures that:
- The P-Chain is fairly compensated for its role in coordination and messaging.
- Entry barriers remain low (no large upfront stake).
- Network economics stay balanced and adaptive.
Validators will need to periodically refill their P-Chain balances—similar to paying a subscription—to maintain uninterrupted operation.

Why ACP-77 Matters: Benefits Across the Ecosystem
ACP-77 isn’t just a technical upgrade—it’s a strategic evolution that unlocks new possibilities for both institutional and retail participants.
For Enterprises and Regulated Entities
Organizations in finance, healthcare, or government sectors can now deploy compliant, permissioned L1s without being entangled in public chain risks. By opting out of mainnet validation, they avoid processing potentially non-compliant transactions while still benefiting from Avalanche’s high throughput and low latency.
For Decentralized Projects and Retail Users
Smaller teams and individual developers gain access to a more inclusive environment. Lower hardware and capital requirements mean that community-run validators can meaningfully contribute to network security and governance.
Additionally, projects can design custom staking mechanisms aligned with their tokenomics—fostering greater engagement and alignment with users.
For the Broader Avalanche Network
By reducing centralization risks and encouraging diverse L1 deployments, ACP-77 strengthens the overall resilience and adoption potential of the Avalanche ecosystem. With sustainable economics powered by dynamic fees, the network becomes more adaptable to changing conditions.
Frequently Asked Questions (FAQ)
Q: What is ACP-77?
A: ACP-77 is a community proposal that redefines how Avalanche Layer 1 blockchains operate by removing mandatory mainnet validation and introducing dynamic fees for P-Chain services.
Q: Do Avalanche L1s still require 2,000 AVAX staked?
A: No—under ACP-77, the 2,000 AVAX staking requirement is eliminated for standalone Avalanche L1 validators. Each L1 can set its own staking rules independently.
Q: How does ACP-77 improve decentralization?
A: By lowering hardware and financial barriers, more entities—including individuals and small teams—can participate as validators, leading to a more distributed and resilient network.
Q: What replaces the staking requirement?
A: Instead of a large upfront stake, validators pay ongoing dynamic fees to the P-Chain based on resource usage and network demand.
Q: Can regulated institutions benefit from ACP-77?
A: Yes. Institutions can run compliant, permissioned L1s without validating the public mainnet, reducing legal and operational risks.
Q: Is cross-chain communication still supported?
A: Absolutely. Cross-L1 messaging continues via Avalanche Warp Messaging (AWM), with the P-Chain managing validator metadata and routing messages securely.
