Solana (SOL), a layer 1 proof-of-stake blockchain, has recently introduced its version 1.16 update, which includes the implementation of “Confidential Transfers” to enhance user privacy. This update focuses on encrypted Solana Program Library (SPL) token transactions, prioritizing confidentiality rather than anonymity.
After ten months of development and an audit conducted by Halborn, a blockchain security firm, the adoption of version 1.16 by Solana’s network of validators has reached a majority. This demonstrates the commitment to ensuring the stability and security of the platform.
According to an announcement by Solana’s infrastructure provider Helius, the update underwent rigorous testing, with version 1.16 running on testnet since June 7, 2023. The involvement of volunteer and canary nodes played a crucial role in identifying and resolving any issues during the testing phase. Additionally, Solana Labs deployed canary nodes on mainnet-beta to monitor the stability of version 1.16 under real-world conditions.
Solana employs a feature gate system to prevent consensus-breaking changes, ensuring that validators running older versions do not fork off the canonical chain. Moreover, any consensus-breaking changes now require a Solana Improvement Document (SIMD) and increased transparency through documentation.

The introduction of Confidential Transfers by Token2022 utilizes zero-knowledge proofs to encrypt balances and transaction amounts of SPL tokens. This advancement places a strong emphasis on protecting user privacy.
Looking ahead, Solana Labs plans to adopt a more agile release cycle, targeting smaller releases approximately every three months. This approach will allow for continuous improvements and faster adoption of new features.
Solana has seen significant growth in its Total Value Locked (TVL) throughout this year, nearly doubling since the beginning of 2023 and currently boasting a TVL of 30.95 million SOL, according to a report by Nansen. Monthly transactions on the Solana network have remained relatively stable, with an increase in vote transactions, encompassing both vote and non-vote transactions.
Nansen also highlights Solana’s implementation of innovative solutions such as state compression and isolated fee markets to address prominent issues within its tech stack. One remarkable solution, state compression, has substantially reduced the cost of non-fungible token (NFT) minting on Solana by over 2,000 times. For instance, the cost of minting 1 million NFTs before the introduction of state compression would have amounted to approximately $253,000. However, with state compression enabled, the cost is significantly reduced to just $113. In comparison, minting a similar collection size on Ethereum would cost approximately $33.6 million, and on Polygon, it would amount to around $32,800.
Additionally, the liquid staking landscape on Solana is experiencing rapid growth, with leading platforms like Marinade Finance, Lido Finance, and Jito taking the forefront. However, despite this growth, the current amount of staked SOL in Solana’s liquid staking protocols accounts for less than 3% of the total staked SOL, indicating substantial room for expansion.
While Solana’s native token, SOL, continues to exhibit substantial gains across all timeframes, it is essential to closely monitor the uncertainty surrounding FTX/Alameda’s SOL holdings. With FTX holding over 71.8 million SOL, representing approximately 17% of the circulating supply and 13% of the total supply, temporary risks to Solana’s growth trajectory may arise.
In conclusion, Solana’s version 1.16 update with Confidential Transfers enhances user privacy and strengthens the overall security of the platform. With a commitment to continuous improvement and the implementation of innovative solutions, Solana is well-positioned for further growth and adoption within the blockchain industry.
