| # Summary | ||
|
|
||
| This feature introduces a special trits encoding to Bee that might be referred to as `9trits/2bytes`, `9t/2b`, or simply `9/2`, or maybe even `4.5trits/byte` encoding. In comparison there is the `10trits/2bytes`, `10t/2b`, or `5trits/byte`, or just `10/2` alternative encoding which is currently used in IOTAs reference implementation IRI. In contrast to that the `9/2` encoding is less memory/bandwidth efficient, but on the other hand is more optimized for byte-wise data processing. This encoding was successfully used already in the Ict node software which was intended to be able to run on weaker devices like Raspberry Pis which is also a primary objective for the Bee node framework. It can be expected that this encoding will positively affect a node's performance by: |

Yeah, we really need to come up with better naming method for this. Vlad has a rule for this which is TE. So TE1 means 1 trit per byte, TE5 mean 5 trits per byte. What do you think.

| **Example transaction implementation based on 9/2 encoding**: This example assumes that a trivial trimming algorithm is used that only trims the 0 bytes from the signature message fragment. |

Really appreciate the example. We may also need to know what basic data structure looks like (maybe like #5 )

Could you provide how to interact with hashing? Like could it do operations directly or need some conversions.
|
Can you add a paragraph on how conversion from/to raw trits would work ? |
