The Avalanche community has introduced a groundbreaking proposal, ACP-77, which promises to redefine how Avalanche Layer 1 (L1) blockchains operate and are secured. This initiative aims to enhance flexibility, reduce barriers for validators, and foster a more inclusive and scalable ecosystem.
Originally known as subnets, Avalanche L1s are sovereign, application-specific blockchains that can be customized to meet diverse needs. They have attracted significant interest from both crypto-native projects and institutional players looking to deploy tailored Web3 solutions.
The Current Challenge for Avalanche L1 Validators
Under the existing system, validators on any Avalanche L1 are required to also validate the Avalanche Primary Network. This network includes the Contract Chain (C-Chain), Platform Chain (P-Chain), and Exchange Chain (X-Chain).
Validating the Primary Network demands substantial resources. Validators must allocate at least 8 AWS vCPUs, 16 GB of RAM, and 1 TB of storage. More significantly, they are mandated to stake a minimum of 2,000 AVAX tokens.
While this stake was manageable at launch, the appreciation of the AVAX token has increased the financial commitment significantly. At previous market peaks, this stake was valued at over $250,000; it currently represents a substantial financial barrier, hindering the decentralization of validator sets and potentially limiting the network's long-term growth and resilience.
What is Proposal ACP-77?
ACP-77 is a community-driven proposal designed to overhaul the economic and operational model for Avalanche L1s. Its core principle is to grant these sovereign chains greater autonomy while ensuring the sustainability of the overarching network.
Achieving Sovereignty for L1s
The most transformative aspect of ACP-77 is the decoupling of Avalanche L1 validation from Primary Network validation.
- Elimination of Mandatory Primary Network Validation: L1 validators will no longer be required to validate the Primary Network.
- Reduced Operational Costs: This separation drastically lowers the hardware and staking costs associated with becoming a validator.
- P-Chain Synchronization: Validators will only need to sync with the P-Chain, which manages cross-L1 communication via Avalanche Warp Messaging (AWM) and tracks validator sets.
This shift is a milestone for horizontal scaling, enabling multiple truly sovereign blockchains to operate concurrently within the Avalanche ecosystem.
Implementing a Dynamic Fee Model
To ensure the Primary Network remains economically sustainable without the upfront stake from L1 validators, ACP-77 introduces a new dynamic fee mechanism on the P-Chain.
This system moves away from fixed per-transaction fees to a model where Avalanche L1 validators pay ongoing, variable fees. These fees are calculated based on factors like the total number of L1 validators registered on the P-Chain and overall network utilization.
The fee adjusts dynamically: it increases when the total number of validators exceeds a target utilization threshold and decreases when it is below. This ensures validators are continuously contributing to the network's health proportionate to the load they impose.
In practice, an L1 validator's balance on the P-Chain will gradually deplete and must be periodically replenished to maintain uninterrupted operation. 👉 Explore more strategies for managing network fees
The Benefits of Adopting ACP-77
The proposed changes are designed to create a win-win scenario for all participants in the Avalanche ecosystem.
- For Institutional L1s: Regulated entities can now operate as validators on their own permissioned L1s without being forced to validate the permissionless Primary Network. This is crucial for meeting specific compliance and regulatory requirements.
- For Retail-Focused L1s: Projects can attract a more decentralized and diverse set of validators thanks to the significantly lower entry barriers, enhancing network security and trust.
- For the Entire Ecosystem: By making validation more accessible, Avalanche can foster a larger, more robust, and innovative ecosystem of application-specific blockchains, ultimately driving greater adoption.
In summary, ACP-77 redefines the relationship between sovereign L1s and the Primary Network. It returns sovereignty to the L1s themselves, allowing them to set their own validator rules, while ensuring the P-Chain is fairly compensated for its critical role in coordination and security.
Frequently Asked Questions
What is the main goal of ACP-77?
The primary goal of ACP-77 is to lower the barriers to becoming an Avalanche L1 validator by removing the requirement to validate the Primary Network and stake 2,000 AVAX. It aims to increase validator decentralization and allow L1s to operate with greater sovereignty.
How does the new dynamic fee model work?
Instead of a fixed fee, L1 validators pay ongoing dynamic fees to the P-Chain. These fees are based on network load and the total number of validators. Fees adjust up or down automatically to ensure the economic sustainability of the Primary Network.
Does this proposal improve regulatory compliance?
Yes. Institutions can now run validators for their private, permissioned L1s without exposure to the public Primary Network. This isolation is a key advantage for entities operating under strict regulatory frameworks.
What happens to the existing 2,000 AVAX staking requirement?
If ACP-77 is adopted, the mandate for L1 validators to stake 2,000 AVAX to secure the Primary Network will be eliminated. Validators will only need to meet the staking requirements set by their specific Avalanche L1.
How does this affect the security of the Primary Network?
The security model shifts from upfront capital staking to a continuous fee-based model. The dynamic fees ensure the Primary Network is constantly funded for the critical work it performs, maintaining its security and functionality.
Will this change how Avalanche Warp Messaging (AWM) works?
No. Cross-L1 communication through Avalanche Warp Messaging will continue to function seamlessly. The P-Chain will still be responsible for coordinating this communication between different sovereign L1s.
