# Membership Request Hi, I am Kian Paimani, known as @kianenigma. I have been working on Polkadot/Kusama through Parity since February 2019 and I can categorize my main contributions to Polkadot's ecosystem as follows: 1. Maintaining and developing the staking sub-system. 2. General FRAME development, especially testing and quality assurance. 3. Polkadot-native side-projects. 4. Education > My first contribution to Polkadot is also indeed related to staking: paritytech/substrate#1915 ### Staking system I joke as the Polkadot staking to be both my blessing and my curse over the years. I started working on it since the first days that I joined this ecosystem and the work [is ongoing ever since](https://github.com/orgs/paritytech/projects/33/views/9). In the past, I focused on making sure that the staking system is secure and to some extent scalable. More recently, I coordinated the (imminent) launch of Nomination Pools. Nowadays I also put an extra effort on making sure that this sub-system of Polkadot is *sustainable*, through code refactor and educating other core developers. Lastly, I have been the main author of the [Polkadot staking newsletter](https://gist.github.com/kianenigma/aa835946455b9a3f167821b9d05ba376), which is my main attempt at making the entire complexity and development of this part of the protocol transparent to the end-users. I expect myself to contribute *directly* to the staking system for at least another ~12, if not more, and afterwards having the role of an advisor. Some notable contributions: - paritytech/substrate#4517 - paritytech/substrate#7910 - paritytech/substrate#6242 - paritytech/substrate#9415 - paritytech/polkadot#3141 - paritytech/substrate#11212 - paritytech/substrate#12129 ### FRAME Historically, I have contributed a variety of domains in FRAME, namely: - Early version of the weight system paritytech/substrate#3816 paritytech/substrate#3157 - Early version of the transaction fee system - Primitive arithmetic types paritytech/substrate#3456 - Council election pallet paritytech/substrate#3364 Many of which were, admittedly, a PoC at most, if not considered "poor". I am happy that nowadays many of the above have been refactored and are being maintained by new domain experts. These days, I put most of my FRAME focus on testing and quality assurance. Through my work in the staking system, I have had to deal with the high sensitivity and liveness requirement of protocol development first hand (I believe I had to do among the [very first storage migrations](paritytech/substrate#3948) in Kusama) and consequently I felt the need to make better testing facilities, all of which have been formulated in https://forum.polkadot.network/t/testing-complex-frame-pallets-discussion-tools/356. Some relevant PRs: - paritytech/substrate#8038 - paritytech/substrate#9788 - paritytech/substrate#10174 Regardless of wearing the staking hat, I plan to remain a direct contributor to FRAME, namely because I consider it to be an important requirements of successfully delivering more features to Polkadot's ecosystem. ### Polkadot-Native Side Projects I have started multiple small, mostly non-RUST projects in the polkadot ecosystem that I am very happy about, and I plan to continue doing so. I have not yet found the time to make a "polished product" out of any of these, but I hope that I can help foster our community such that someday a team will do so. I consider my role, for the time being, to *put ideas out there* through these side projects. - https://github.com/substrate-portfolio/polkadot-portfolio/ - https://github.com/kianenigma/polkadot-basic-notification/ - https://github.com/paritytech/polkadot-scripts/ - https://github.com/paritytech/substrate-debug-kit/ ### Education Lastly, aside from having had a number of educational talks over the years (all of which [are listed](https://hello.kianenigma.nl/talks/) in my personal website), I am a big enthusiast of the newly formed Polkadot Blockchain Academy. I have [been an instructor](https://singular.app/collectibles/statemine/16/2) in the first cohort, and continue to contribute for as long and as much as I can, whilst still attending to the former 3 duties. --- With all of that being said and done, I consider myself at the beginning of the path to Dan 4, but happy to start at a lower one as well.

This PR refactors some leftover from the weight / fee system. The incentive is that I intend to write a document soon about this concept. Going through the details, I found it to be pointless to do so, given that I also intend to refactor some of it. Once this is merged, I will make a conceptual doc about weight.
Refactors
SignedExtensionfor that takes fees. Based on historical dilemmas regarding transaction fees (see here), I have named it transaction-payment, referring to a minimum inclusion payment that each transaction pays, nothing more.transaction-paymentdoes. System module only takes care of maintaining a per-block weight and length accumulator.transaction-paymentinterprets this as desired to deduct fees.transaction-paymentdoes.Fairly speaking, while the diff is big, the PR is almost insubstantial and does not alter any significant logic. The only logic change is the fix of #3291
Still to do
Maybe here, maybe another PR:
deprecateDONE here Better Parameterisation for Fee system #3823TARGET_BLOCK_FULLNESSand attach it to the type that is used asFeeMultiplierUpdate. (probably learn fromDealWithFeesand how they attach a const to a type).
