IOTA 1.5, the Mainnet’s intermediate stage before Coordicide is complete.
11 February 2020
A simpler, conflict-ignoring approach (valid for the pre-coordicide era) that allows for faster and more efficient tip selection, eliminates certain attacks and significantly reduces the need for reattachments.
Allows node software to find neighbors automatically.
Universally-random tip selection
Improves the performance of the tip selection algorithm, allowing nodes to find tip transactions faster.
Leads to the network being able to confirm more transactions per second.
Request for comments
By adding support for a second signature scheme, the IOTA protocol will support reusable addresses.
Move from the current Bundle construct and use simpler atomic transactions instead. This will reduce network overhead and maintainability of node software.
Allows for faster and more exact conflict handling, add support for colored coins, and deals with possible scenarios of reattaching invalid transactions.
Binary transaction layout
This allows us to work on binary data, for validation, IO and other processing without the need to have many binary-ternary conversions as in the current node software.
