Understanding why @aztecnetwork sequencer node runners are so important Been digging deeper into Aztec lately and I think many people underestimate how important sequencer and node runners are especially now with 17K+ active nodes. But how do these transactions get processed that is where sequencer nodes come in Sequencers are the first ones to receive your transaction they collect them, order them fairly, bundle them into batches 'aka rollup blocks' and then kick off the zero knowledge proof generation process without sequencers = no ordering without ordering = no batch without batch = no proof and without proof = nothing lands on ethereum mainnet. ZKPs aren't cheap to compute so the sequencer helps manage that too they work with prover nodes that handle the heavy zero-knowledge math to make sure that each batch of transactions is valid, once that is done they submit it all to ethereum L1 with one final compressed proof

Before 2020 most of crypto's volume wasn't stablecoin based that is changed now a huge chunk of usage is just stablecoin transfers raw value moving around onchain. and that is real product market fit fast, borderless, dollar denominated money. In places with high inflation Brazil, Argentina and parts of Africa stablecoins are being used like real money in Sub Saharan Africa, they account for 43% of crypto transaction volume. But even with $246B+ in stablecoin market cap it is still early, that is 1% of global M2. so in the grand scheme of global money this is tiny but it is growing fast. and now we are seeing stablecoins used in actual commerce not just trading #Tether recently settled an oil trade in USD. we have basically built a better cheaper and faster way to move money globally the problem is scaling, this is really hard when money moves at this scale the chain can not just be secure it has to be efficient, low cost and reliable under pressure consensus gets harder slashing has to be meaningfuf

Why @PlasmaFDN consensus design actually scales scaling blockchains isn't just about tps, it is about coordination getting validators to agree FAST & SECURELY but consensus at scale it is really hard here is how Plasma makes it work= why is consensus hard at scale more validators = more messages = exponential complexity in worst cases, it can degrade to quadratic communication that is a bottleneck for performance & reliability. instead of everyone validating every block plasma picks a small set of validators each round it is faster lighter and avoids message overload. how does plasma pick the committee via a cryptographically secure random process... weighted by proof of stake more stake = more chance of being chosen. slashing= keeping validators honest stake slashing = you misbehave you lose funds reward slashing = misbehave slightly lose your rewards.
