Previously in its beta version of Amethyst 3.4.0 is the product of a long process of testing and refinement. The stable release ossifies the following 6 changes:





1.Deterministic wallets: previously wallet keys and passwords were kept inside of the wallet file itself. While this process bolsters security if someone loses his password his wallet and funds are lost to him forever. With this update Bytecoin has introduced Mnemonic passphrases to their platform, allowing people with the new version of the wallets to regain lost access."6 changes in Bytecoin development"







2. Unlinkable addresses: via CryptoNote research and development Bytecoin developers have figured out a way to create entirely unlinkable addresses. This allows for groups of wallet addresses to share the same view keys without an outside observer being able to tell if these addresses have a common derivative key. This update picks up where the user Payment ID and Shared View Keys features left off.



3. Implicit Wallet address History: only transaction senders can restore destination addresses from transaction data by adding a single byte per output to the blockchain. The Bytecoin devs have enabled these changes for legacy addresses, getting rid of public transaction keys altogether.



4.Auditable view-only wallets: Bytecoin developers have improved the cryptography behind view-only wallets. Now, auditable file-versions of wallets can be shared in the Bytecoin community with the option of letting auditors also view the destination addresses on transactions.



5.Blocksize adaptation: Bytecoin devs have introduced direct voting as a method for dealing with the problem of block size adaptation. In this paradigm, each miner states what his preferred blocksize is and then the median of the gathered votes becomes the maximum block size.



6. Signature pruning key: signatures password take up to 80% of the blockchain and often go unchecked beyond the last checkpoint due to the computation power they require. To free up from space, byte coin developers have figured out a way to put signatures.
