I've published an old writeup of mine that collecting dust for a while. It is a developer's guide into @Polkadot, highlighting different paths that a developer has in this ecosystem, and how they all connect to one another.

The argument of a sharded and non-sharded TPS differing is valid. But the answer is not as simple as @Justin_Bons's "any sharded system can achieve millions TPS". 🧵 Let's dive into the meaning of TPS in a sharded system:

Parity staking miners have been serving DOT/KSM networks with NPoS computation, earning a small reward in return. These rewards have been used for maintenance transactions, and the surplus sent to treasury. This time around, we donated everything to Subsocial's Humanitarian fund.
We have set up a way to donate crypto funds to support #Ukraine. Many #Dotsama tokens are supported including: $DOT $KSM $ACA $ASTR $KAR $SDN $PHA $BNC $KILT $QTZ $AIR $TEER $XOR $PCX. Learn more 👇. #StandWithUkraine #UkraineUnderAttack #UkraineRussiaWar.

On that note, if you find yourself suited to be a runtime/FRAME developer, but you are particularly interested in working on a next-gen staking system, send an email to kian@parity.io, or apply at
Also looking for a few engineers for other teams at @ParityTech:. 1) Engineers to develop cross-chain messaging (XCM) for @Polkadot.2) Technical writers to make @substrate_io the friendliest platform to build on. 3) Full stack developers to simplify end-user experiences.

> In general, there are 28602 (or 64.21%) nominators that have at least one inactive validator in their targets. This might sound unimportant, but it is a subtle detail that leads to @Polkadot's NPoS achieving more uniformed degree of economic security across its validators.

I always loved to see a `top` equivalent for Polkadot (`ptop`) that looks at @Polkadot as a multi-core computer, and shows the status and resource utilization of each core. While slightly different, this amazing UI is pretty much it! 🤩.
as a late christmas gift to the polkadot (& kusama) ecosystem i would like to present the following: it's a real-time dashboard (thank you to conduit for the inspo) where you can keep track of all your favorite chains at once. all complaints and comments

I am glad Polkadot's pessimistic/cynical rollup approach finally has a name and a formal paper: ELVES. This is the reason why Polkadot can have two mututally exclusive properties: shared security, sharded execution.

Factual statement: . Parachains and rollups (with all their subcategories) are the same in *what* they do, and different in *how* they do it. What they do: Scale out an L1 to have more overall blockspace/bandwidth. How they do it: Differs as per all the comments in the below.
@csaint02 @ellipsis_labs @Polkadot yes i'm going to get technical because it's a technical term with a technical definition and parachains are not rollups. you're only confusing people more, nobody in ETH land is going to be swayed by this god awful marketing because it's just factually inaccurate.

Excellent statement and reminder. And probably one of those mental-model "parasites" that spread very quickly in the blockchain space years ego, was echoed a million times in misled blogs and articles, and is very hard to correct nowadays.
New year reminder:. Blockchain is not a database; it's a verification machine! Only consensus critical information should be stored in a blockchain.

"In a world too often governed by corruption and arrogance, it can be difficult to stay true to one’s philosophical and literary principles.".
.@Polkadot isn’t just another project chasing numbers. (Let’s be honest, if we wanted to, we’d easily be #1! 🙂). For us, success isn’t about short-term gains or flashy metrics. It’s about building something meaningful — staying true to Web3 ideals: privacy, decentralization, and

This thread sheds a lot of light into the unique, technology-first position Polkadot has in the blockchain industry, and a primary reason why I am glad to be a part of it.
The @Web3foundation recently released a statement saying that @Polkadot DOT token has morphed, from a Security to Software. In a follow up podcast, they go much deeper into the details. I break down everything for you in this thread, so follow along.

This is the most straightforward way I can put JAM and @Polkadot in the spectrum of execution sharding in blockchains, and homogeneity of those shards.

You can learn about what @Polkadot chains' metadata is, and how to enable the hashed metadata for generic @Ledger support straight in the Polkadot-SDK rustdocs:. ->

This adds a 4th quality to our list of metrics for blockspace, and Polkadot, through the JAM upgrade, is the sole project inventing its way into providing it.

Sharing the clickbaity part of my notes from @Web3summit: . Resilience is a Spectrum Fallacy: . not a choice, but a reaction to the fact that the system failed to scale while maintaining resilience, therefore it changed its narrative to argue resilience was not needed at all.

@rphmeier puts it best that blockspace is not just a quantitative measure, it also has qualitative. And when comparing TPS, sharded or non-sharded, it should be taken into account.

JAM upgrade is a realization that even @Polkadot's uncompromising solution to sharding is not enough – we also need flexible boundaries among shards, allowing them to synchronously compose, should they wish to communicate often.

@ameensol @jon_charb @dankrad @koeppelmann If only there was an Ethereum co-founder who left in 2016 to build exactly that. Jokes aside, I hop as Ethereum and Polkadot's architecture start to more alike we see more collab between the two.

What often gets lost in translation is that Polkadot's sharded architecture achieves 5/6 figure TPS, with all the 3 above criteria uncompromised. Most, if not all, of the "trivial 1m TPS sharded systems" are butchering those 3 criteria to increase TPS, while @Polkadot decided
