Avalanche has launched Avalanche9000, the most significant upgrade since its mainnet debut in 2020. Rolled out on December 16, 2024, this transformative update redefines how developers build and deploy Layer 1 (L1) blockchains on the Avalanche network. By enhancing cross-chain interoperability, reducing entry barriers, and introducing advanced technical capabilities, Avalanche9000 positions AVAX as a leading platform for scalable, customizable, and compliant blockchain ecosystems.
This article explores what Avalanche9000 is, the core changes it introduces, and how it shapes the future of decentralized application development and enterprise adoption.
What Is Avalanche (AVAX)?
Avalanche is a high-performance Layer 1 blockchain launched in September 2020. Designed to solve the blockchain trilemma—balancing scalability, security, and decentralization—it supports a wide range of applications including decentralized finance (DeFi), real-world asset tokenization (RWA), and memecoins.
The network operates using three core components:
- Avalanche Consensus: A unique Proof-of-Stake (PoS) mechanism enabling fast finality—just 2 seconds—and high throughput with a theoretical maximum of 357 transactions per second (TPS).
Primary Network: The foundational layer that connects all chains on Avalanche. It includes:
- C-Chain for smart contracts,
- P-Chain for coordinating validators and subnet creation,
- X-Chain for asset creation and trading.
- Subnets (now rebranded as Avalanche L1s): Customizable, sovereign blockchains that run parallel to the Primary Network. These can be tailored for specific use cases, industries, or regulatory requirements.
One of Avalanche’s key strengths is its Ethereum Virtual Machine (EVM) compatibility, which allows developers to easily port Ethereum-based dApps to Avalanche with minimal changes. This interoperability accelerates innovation while reducing development time.
The native cryptocurrency, AVAX, powers the ecosystem by enabling staking, transaction fees, and governance. As of late 2024, AVAX ranks among the top 15 cryptocurrencies by market cap, reflecting strong investor confidence and ecosystem growth.

What Is Avalanche9000?
Avalanche9000 marks the largest technical evolution in Avalanche’s history. Its primary goal is to streamline the deployment of Avalanche L1s—formerly known as Subnets—by making them easier, cheaper, and faster to launch.
Prior to this upgrade, launching a new L1 required each validator to stake 2,000 AVAX (approximately $103,740 at December 2024 prices) and meet strict hardware requirements (8 vCPUs, 16 GB RAM, 1 TB storage). These conditions created high barriers for startups and regulated institutions alike.
Avalanche9000 removes these constraints through a suite of protocol improvements known as Avalanche Control Proposals (ACPs). Below are the key upgrades included in the rollout:
ACP-77: Revolutionizing Validator Management
This is the cornerstone of Avalanche9000. ACP-77 fundamentally changes how L1s interact with the Primary Network by:
- Rebranding Subnets to Avalanche L1s to reflect their status as independent blockchains.
- Decoupling L1 validators from Primary Network validators, eliminating the need to stake 2,000 AVAX per node.
- Transferring validator set management from the P-Chain to smart contracts on individual L1s, giving chains full control over their validator selection.
- Introducing a continuous dynamic fee model, where L1s pay low-cost fees to Primary Network validators instead of staking large amounts of AVAX.
This shift dramatically lowers entry costs and enables permissioned or regulated entities—such as financial institutions or government-linked projects—to deploy compliant L1s without participating in permissionless validation.
ACP-125: Lowering C-Chain Fees
The minimum base fee on the C-Chain drops from 25 nAVAX to just 1 nAVAX, significantly reducing transaction costs for users and developers. This makes small transactions more viable and improves user experience across DeFi and NFT platforms.
ACP-103: Dynamic Fee Mechanism for X & P-Chains
Introduces dynamic fee adjustments on the X-Chain (for assets) and P-Chain (for staking), preparing Avalanche for a future multidimensional fee structure similar to Ethereum’s EIP-1559. This helps prevent congestion and stabilizes network usage during peak demand.
ACP-113: On-Chain Randomness
Enables verifiable, non-cryptographic random number generation—critical for gaming, lotteries, NFT minting, and other dApps requiring fairness and unpredictability.
ACP-20: Enhanced Security
Adds support for Ed25519 TLS certificates in peer-to-peer communications, improving node authentication and network security across the board.
ACP-131: EVM Upgrades via Dencun Integration
Implements key Ethereum Improvement Proposals (EIPs) from Ethereum’s Dencun upgrade—such as EIP-4844 (proto-danksharding)—into Avalanche’s EVM environment. This enhances scalability and paves the way for rollup-friendly infrastructure.
ACP-118: Streamlined Messaging
Standardizes AppRequest payloads for signature aggregation, simplifying communication between nodes and improving efficiency in cross-chain messaging.
Why Avalanche9000 Matters: Key Benefits
The implications of Avalanche9000 extend beyond technical improvements. Here’s how it transforms the ecosystem:
✅ Lower Barriers to Entry
Projects no longer need massive capital to stake AVAX or run heavy infrastructure. Startups can now launch production-grade L1s at a fraction of the previous cost.
✅ Full Customization & Control
With validator management moved on-chain via smart contracts, teams can define their own rules—whether open participation, geographic restrictions, or compliance protocols—making Avalanche ideal for enterprise use.
✅ Regulatory Compliance Built-In
Financial institutions or government-backed initiatives can deploy private or hybrid L1s with tailored access controls, meeting legal requirements without sacrificing performance.
✅ Interoperability at Scale
All L1s connect natively through Avalanche Interchain Messaging (ACM), allowing seamless asset and data transfers across chains. Combined with shared liquidity pools, this creates a unified ecosystem where value flows freely.

Future Outlook: Accelerating Ecosystem Growth
Avalanche9000 sets the stage for explosive growth. By removing friction in L1 deployment, it invites a new wave of innovation—from DeFi protocols to central bank digital currency (CBDC) pilots.
In anticipation of this upgrade, Avalanche secured $250 million in funding from top-tier investors like Galaxy Digital, Dragonfly, and ParaFi Capital. This capital will fuel developer grants, ecosystem partnerships, and global expansion efforts centered around Avalanche9000.
Additionally, enhanced EVM compatibility ensures continued synergy with Ethereum’s developer community. As more projects adopt rollups and modular architectures, Avalanche’s support for proto-danksharding makes it a strategic hub for scalable dApp deployment.
