In the blockchain world, gas has long been something users both need and hate. It’s the cost we pay for each transaction, each time a smart contract is executed. But as blockchain evolves, a new challenge is emerging, a problem that could stifle the future of decentralized networks even more than gas: state bloat.
State bloat is like a messy attic of blockchain. Over time, it fills up with data — some of it crucial, but much of it outdated or redundant. And just like a homeowner has a hard time finding what they need in a cluttered attic, a blockchain slowed down by state bloat becomes more expensive and difficult to scale.
Fortunately, Altius brings a smart and efficient solution for managing blockchain state, ensuring that the network can grow without sacrificing speed or decentralization. Let's explore how blockchain stores data, what state bloat is, and how Altius is changing the game.
How Does Blockchain Store Data?
Blockchain is fundamentally a distributed ledger that records transactions. But beyond tracking value transfers, blockchain also maintains something called state. The state is the current snapshot of all accounts, smart contracts, and relevant data at any given time. Think of it like the memory of the blockchain — where everything from your token balance to variables in a complex DeFi protocol is stored.
Every time a transaction occurs or a smart contract is executed, the state is updated. For example:
When you send ETH to someone, the state changes to reflect your new balance and the recipient's.
When a decentralized exchange (DEX) processes a transaction, the state updates information about liquidity, token reserves, and user positions.
State is vital because it allows the blockchain to know the current status without having to replay the entire transaction history from the beginning. However, as the number of transactions increases and more smart contracts are deployed, the state also grows. And that’s when the problem begins.
What is State Bloat?
State bloat is the excessive growth of state in blockchain. As the state bloats, nodes (computers running the blockchain) need more resources to store, access, and update this data. Over time, state bloat can:
Slowing down transaction processing.
Increasing node operating costs.
Creating difficulties for new nodes joining the network.
Simply put, state bloat is like a balloon that keeps inflating — if unchecked, it will pop or make the system too heavy to function efficiently.
The Reality of State Bloat Through Numbers
Take a look at some statistics to clearly see the scale of the problem:
Ethereum: As of 2023, the state size of Ethereum is around 200 GB, increasing by 10-20 GB each year. When launched in 2015, its state was almost negligible, but now it has become a huge burden.
Bitcoin: While it does not have state like Ethereum, Bitcoin uses a set of UTXOs (Unspent Transaction Outputs) to track unspent coins. This set has grown from a few MB in 2009 to over 4 GB in 2023.
Solana: With high processing speeds, Solana's state has also surged. In 2022, its state was around 100 GB and continues to grow as more decentralized applications (dApps) are built.
This growth rate is not sustainable. If uncontrolled, state bloat could choke the largest blockchain networks.
The Dangers of State Bloat
State bloat is not just a technical issue; it also has serious consequences:
Slow Synchronization Time: New nodes must download and process the entire state to join the network. As the state bloats, this process takes longer and requires more capacity. With Ethereum, fully syncing a node can take several days, even weeks.
High Storage Costs: Operating a full node requires storing the entire state. As the state size increases, hardware costs also rise. This discourages individuals and small organizations, leading to fewer nodes and more centralized networks.
Slow Transaction Processing: A larger state means nodes take longer to access and update data, reducing transaction speed and network throughput, especially during peak hours.
Centralization Risk: As operating a node becomes expensive, only well-resourced organizations can afford to participate. This undermines the decentralization of blockchain.
Hindrance to Development: For new blockchains or Layer 2 solutions, state bloat can be a significant barrier. If a network does not scale effectively, it will not attract developers or users.
What Do Validators Usually Do to Combat State Bloat?
Validators and node operators have come up with various ways to cope with state bloat, but they are often just temporary solutions:
State Pruning: Removing unnecessary historical state data. Ethereum has implemented some pruning techniques, but it has not stopped the state from continuing to grow with new transactions.
Light Client: Lightweight clients do not store the entire state but rely on full nodes to retrieve information. However, this reduces security and decentralization because lightweight clients must trust other nodes.
Sharding: Some blockchains like Ethereum 2.0 split the network into smaller shards to distribute the state load. Nevertheless, sharding is complex and does not fully resolve the issue.
State Expiry: Some proposals, like those from Ethereum, aim to store old data, reducing storage costs. But this is still just an idea and has not been implemented.
These solutions may alleviate the issue, but they do not address the root cause: the inefficient way blockchain stores and manages state.
Altius: The Superior Solution for State Management
Altius not only patches the issues but also reshapes how blockchain handles state from the ground up. Here’s how Altius excels:
Parallel Storage Model
Altius uses a distributed state storage model, allowing independent operations across multiple shards. Think of it as multiple well-organized warehouses, where data is split into easily accessible areas instead of being piled up in a cramped space.
Benefits: With horizontal scalability, as the network grows, simply add shards to handle the increased state. State bloat is no longer a problem.
Instruction-Level Parallelism (ILP)
Altius optimizes smart contract execution with ILP, processing commands in parallel to reduce conflicts and enhance efficiency. This is not only faster but also reduces the amount of state data generated.
Benefits: Fast and efficient execution keeps the network lightweight and more agile.
Application Code Evaluator (ACA)
Altius encourages developers to write efficient code through ACA, assessing and rewarding optimized smart contracts that produce less state bloat.
Benefits: Creating an ecosystem where everyone benefits from a compact state.
Tremendous Benefits of Integrating Altius
Altius is not just a scaling solution; it is a major turning point:
Unlimited Scaling: Thanks to the shard model, Altius is not limited by state size, allowing the network to grow freely.
Low Costs: Optimized storage and execution help reduce node operating costs, keeping the network decentralized and easy to join.
Fast Transactions: Parallel processing and efficient state management ensure smooth transactions even when the network is busy.
Sustainable Future: Altius is compatible with many blockchains, from Ethereum to Solana, being a universal solution for all platforms.
Developer Support: Rewarding optimized code, Altius builds a high-quality developer community.
State is the new gas, but Altius is the solution.
Just as gas once threatened the development of blockchain, state bloat is now the next major challenge. But with Altius, the future looks brighter. Consuming less, storing smarter, and scaling cleaner, Altius ensures that blockchain is not burdened by its own success.
