$SOL $BTC $XRP Solana developers have proposed a plan to eliminate a significant bottleneck to scaling up to millions or even billions of users.
They intend to do this by introducing a “lattice-based” hashing system that reduces the effort needed to keep track of the state of every user account. Hashing is the cryptographic process of turning data into a standardized 64-character code that can’t be reverse-engineered, while the state is a snapshot of the data stored in a blockchain.
So instead of taking a snapshot of every user on the entire blockchain, and “recalculating everything, it will only update accounts that have changed,” explained research firm Republik Labs in an X post. “This is faster, simpler, and uses fewer resources, letting Solana handle millions (or billions) of accounts more easily.” Putting it more simply, Republik Labs suggested thinking of the process as cleaning a house.
“Instead of scrubbing every single room every day, you only tidy up the spaces that got messy,” it said. “This saves time and effort while keeping everything in order.”
At present, the Solana network has to recalculate the state of all user accounts on a regular basis, which requires more work as the number of users grows, making it harder to scale up, the Solana Foundation said in the Jan. 6 proposal.
“The problem comes down to this simple thing, new account creation has to actually create new accounts,” said Solana Labs co-founder Anatoly Yakovenko in an X thread in May. “Which means that a new account has to prove that it is new somehow.”
That’s simple if there is a full global index of all accounts on every node, but it’s also expensive and becomes more so as the network grows, he said. Decentralized exchanges (DEXs) on Solana have been outpacing Ethereum in the past month, with $113 billion in total value locked (TVL) compared to $79 billion for the Ethereum mainnet.
Quantum preparedness
The proposal comes just days after Zeus Network chief scientist Dean Little’s announcement of the availability of quantum-resistant vaults designed to protect users from the possibility that quantum computers could break cryptocurrencies’ encryption. While not mandatory, the Solana Winternitz Vaults generate a new key every time a transaction is made, explained Little in a Jan. 3 Github post.
“Winternitz signatures are for single-use only,” he said. “Each time you sign a message, you reveal ~50% of your private key, lowering your own security guarantees. That is why we close and open new vaults with each spend.”
The new keys should make it harder for quantum computers to attack a public key and break the private key, which is impossible with current computers. Still, quantum computers of this power are said to be a decade or more off.
