Top ZK Rollup Projects of 2023: Review |
https://dev.to/getblockapi/top-zk-rollup-projects-of-2023-review-281m
|
Top ZK Rollup Projects of ReviewZero knowledge rollups ZK rollups ZK rollups ZKRs have emerged as a cutting edge phenomenon in the realm of Web The pivotal role they play in scaling Ethereum has propelled their widespread adoption during the period of In the ensuing discourse GetBlock aims to elucidate the fundamental principles underpinning ZK rollup primitives while showcasing the preeminent projects that harness their potential for DeFi applications Exemplary ZK rollup projects in Key Aspects ZK rollups exhibit a novel approach by offloading certain transactional data from the Ethereum mainnet thereby preserving its computational resources and enhancing the efficiency of its operations Zero knowledge rollups encapsulate cryptographic technology that facilitates data aggregation and verification ZK rollups enable Ethereum based systems to partially process data outside the network s mainnet Utilizing a ZK based framework data compression takes place consolidating information pertaining to thousands of transactions into a singular entity subsequently verified within the Ethereum ecosystem To safeguard the integrity and confidentiality of information ZK rollups generate zero knowledge proofs By leveraging ZK rollups decentralized applications dApps can harness the power of Ethereum at minimal costs and significantly accelerated speeds compared to direct interactions with its mainnet StarkNet zkSync and Aztec have emerged as prominent implementations of ZK rollup technology Prominent Web behemoths such as Coinbase and Polygon Network have launched their zkEVM networks seamlessly integrating Ethereum s code while utilizing ZK rollups for data processing Leading dApps including Aave Uniswap dYdX and Curve have successfully deployed their respective versions on ZK based systems In light of its limitations and obstacles ZK rollup technology stands out as the most promising avenue for scaling Ethereum in terms of transaction throughput and usage costs In what way can ZK rollups facilitate the scalability of Ethereum ZK rollup systems rely on three essential components to ensure their secure and efficient operation Ethereum network s smart contract This smart contract acts as the intermediary between the scaling solution and Ethereum itself Every transaction processed within the ZK rollup system needs to be mirrored on the main network Third party prover The prover plays a crucial role by generating cryptographic proofs to guarantee the validity and integrity of the data processed through the ZK rollup system It is imperative that the data remains uncompromised during the compression process Additionally the entire procedure is executed in a zero knowledge manner ensuring that no party gains access to the transferred information Verifiers ecosystem Verifiers a subset of blockchain validators assume the responsibility of confirming the status of the proofs and submitting them to the Ethereum mainnet In essence ZK rollups employ data compression techniques to process thousands of transactions on Ethereum as a single transaction offering enhanced speed and cost efficiency Throughout this process ZK rollups strive to safeguard data from unauthorized access or tampering Notable ZK rollup projects in A Comparative Overview Projects falling under the ZK rollups category can be broadly classified into two main groups The first group consists of blockchains that utilize ZK rollup technology to scale Ethereum The second group encompasses applications that leverage ZK rollups similar to how they previously utilized Ethereum or Polygon Here are a few examples of ZK rollup blockchains StarkNetzkSyncPolygon zkEVMAztecScrollNow let us summarize the fundamental aspects of some notable ZK rollup

The best Memorial Day tech sales we could findApart from being a time to honor those who ve served our country and the unofficial start of summer Memorial Day also brings a number of sales on various appliances and electronics As we round into the holiday weekend we ve sorted through the cruft and picked out the best tech sales we could find ahead of this Memorial Day The notable deals include off Sony s excellentWH XM headphones Amazon s Fire TV Stick K Max back at an all time low of and Apple s iPad Air down to There are a few sweeping sales on other gear we like as well including Solo Stove fire pits Ooni pizza ovens Samsung storage devices and PC games from the Epic Games Store nbsp Amazon Fire TV streamer dealsAmazon has discounted all of its Fire TV streaming devices ahead of Memorial Day The standout is the Fire TV Stick K Max for which is a price we ve seen several times before but still matches the device s all time low This is the fastest streaming stick Amazon sells plus its remote comes with Alexa voice control baked in If you just want a cheap way to put apps on an older p display the Fire TV Stick Lite is also worth considering at which is more than the lowest price we ve seen nbsp Beyond that the base Fire TV Stick K is down to the standard Fire TV Stick is down to and the Fire TV Cube which blends a K streamer with an Alexa smart speaker is down to an all time low of All Fire TV streamers tend to prioritize Amazon s own content and stuff their UI with ads so we generally recommend Roku and Google streamers to most people The Roku Streaming Stick K is an OK value at its current deal price of though we ve seen it go for less in the past Still if you use services like Alexa and Prime Video on a regular basis or if you just want to save a few bucks the Fire TV Stick K Max is mostly on par with its peers in terms of performance and app support nbsp Sony headphone dealsSony has put a number of headphones and earbuds back on sale including the flagship WH XM for While that s not an all time low it s the first notable discount we ve seen on the noise cancelling over ears since February and a drop from the pair s usual going rate The XMs are the top pick in our guide to the best wireless headphones and we gave them a review score of last year thanks to their powerful ANC lightweight design punchy sound and deep feature set nbsp If you want to save a little extra cash the XM s predecessor the WH XM is also worth a look at Again that s not the lowest these headphones ever been but it s still below their typical street price This pair is slightly bulkier than the XM its sound is a bit boomier out of the box and it has a worse mic for phone calls Its ANC battery life and general feature set are similar though and it can fold up for easier storage The XMs also use an automatic ANC adjustment system which some may prefer to avoid We gave the XM a score of back in Samsung storage device dealsSamsung has kicked off another round of deals on its microSD cards SSDs thumb drives and other storage devices The offers include the GB Samsung Pro Plus the top pick in our best microSD card guide paired with a USB reader for That s off its MSRP and a new low You can also get the card without the reader for a dollar less If you don t need something quite as fast the Samsung Evo Select is the top value pick in that guide its GB model is down to an all time low of as well Besides microSD cards the Samsung Fit Plus an ultracompact flash drive we recommend in our best SSDs guide is back at a low of for a GB model A TB version of the T Shield a rugged version of one of our favorite portable SSDs is down to while the TB model is available for If you re looking for a PCIe Gen SSD to upgrade a PlayStation or high power gaming PC the TB version of the Pro with an integrated heatsink is about less than usual at The speedier Pro meanwhile is down to for a TB unit another all time low Solo Stove saleSolo Stove is running a site wide Memorial Day sale that takes up to percent off a number of its popular mostly smokeless fire pits The discounts include the Bonfire for which is off the medium sized pit s MSRP and off its usual street price What s more you can add the company s Mesa tabletop fire pit for no extra cost if you add it to your cart and use the code FREEMESA at checkout Normally the device goes for The sale also includes the Pi Pizza Oven for which is off its typical going rate We ve sung the praises of Solo Stove s fire pits multiple times in the past and we currently recommend the Pi in our pizza oven buying guide Ooni pizza oven saleOoni makes several of the other picks in our pizza oven guide and this week it s discounted a couple of those as part of its own Memorial Day sale The deals include the Fyra for which is off its MSRP and the Karu for which is a discount Both do well to actually make pies but we recommend the former if you d prefer a more compact oven that runs on wood pellets while the latter is a larger and more versatile option for bigger servings that can use wood charcoal or gas We also recommend the Karu in our guide to the best grills and grill accessories Epic Games Store Mega SaleThe Epic Games Store has rolled out its latest Mega Sale bringing discounts on a number of PC games While the promotion includes a handful of decent price drops its real value comes from the Epic Coupon which takes percent off most purchases of or more The offer applies whether you buy one or multiple games at a time and stacks on top of any existing discounts This brings many games back around their best prices to date Red Dead Redemption II for instance is already on sale for but with the coupon it drops to an all time low of The coupon also works on games that aren t otherwise part of the sale so you can take percent off newer titles like Star Wars Jedi Survivor nbsp and Dead Island which haven t received major discounts elsewhere The former s PC port has had a rocky launch to put it mildly though a few patches have helped stabilize it And because the coupon renews after each eligible purchase you can use it continuously until the promotion ends on June It won t work on pre orders though If you prefer to get your PC games through Steam meanwhile note that Valve s Summer Sale will kick off on June Apple Gift CardIf you pick up a Apple gift card at Best Buy the retailer will throw in a Best Buy gift card for no extra cost The offer also includes a few extended trials to Apple s TV Music and News subscriptions for new and returning subscribers We see this deal periodically but if you shop at Best Buy anyway and plan to use services like the App Store Apple Music or iCloud it essentially gets you a bit of free money Just note that the deal only applies to digital gift cards not physical ones Razer Huntsman MiniThe top pick in our guide to the best percent keyboards the Razer Huntsman Mini is down to for a model with Razer s Clicky Optical switches That s more than the ultracompact gaming keyboard s all time low but still about less than its usual street price If you prefer a quieter switch with a smoother feel while typing a variant with Linear Optical switches is on sale for which is about below its typical going rate Either way we like the Huntsman Mini for its sturdy build quality smooth PBT keycaps and per key RGB backlighting Apple iPad AirThe latest iPad Air is once again down to matching the second best price we ve seen and coming in below Apple s MSRP We gave the Air a review score of last year and call it the best tablet for most people in our iPad buying guide While it lacks the top tier M chip Hz refresh rate and improved speakers of the iPad Pro it provides a similarly elegant design at a much lower price with a better display faster processor and wider accessory support than Apple s lower end tablets Apple Mac MiniApple s entry level Mac Mini is back on sale for which matches the compact desktop s previous all time low This model includes Apple s M chip GB of RAM and a GB SSD Those specs along with the device s lack of upgradeability mean you ll want to stick to relatively light workloads However if that s all you need this is the most affordable route into a competent Mac desktop If you need more storage a version with a GB SSD is also on sale for which is another all time low We gave the Mac Mini with a faster M Pro chip a review score of earlier this year but outside of the CPU bump and a couple extra Thunderbolt ports the devices are virtually identical Apple PencilThe Apple Pencil has dropped to tying the lowest price we ve tracked for the iPad stylus This is roughly below the device s typical street price in recent months and below Apple s MSRP We recommend the Pencil in our best iPad accessories guide For digital artists and note takers it s a consistently accurate pen and the only stylus to offer pressure sensitivity across iPadOS It s also easy to charge and pair since it can attach to the side of a recent iPad magnetically Just make sure your iPad is compatible with this second gen model if you want to take the plunge Intel and AMD CPU dealsIf you re looking to build or upgrade a PC we re seeing a handful of good prices on both Intel and AMD processors Among the better deals available the Intel Core i is down to which is about below the chip s usual going rate and an all time low For something more powerful the Core i F is available for a new low of which is about less than its typical street price This is a strong performer for both gaming and productivity at that price just note that it lacks an integrated GPU If you prefer an AMD build meanwhile the Ryzen X might be worth a look at It s not as good of a value as something like the i F especially since it requires an AM motherboard and DDR RAM to work but it s still a solid mid range option for gaming if you must have a Ryzen PC nbsp Dashlane Premium saleA password manager is a simple but effective way to boost your online security and simplify the amount of login credentials you need to remember Dashlane is one of the better options available in fact it ll soon be a pick in an upcoming buying guide If you want to give the service a try you can get a year of Dashlane Premium for when you use the code MEMDAY or MEMORIAL at checkout That s a percent discount Though Dashlane has a free tier the Premium plan lets you use the service across multiple devices It also includes a bundled VPN a password strength analyzer and dark web monitoring which lets you know if your email addresses have been leaked in data breaches Paramount Plus and Showtime bundleParamount has rolled out a promotion that gives new subscribers three months of its Paramount Premium Showtime bundle for per month or in total That s half off its usual going rate With the glut of streaming TV options available it s hard to call Paramount essential but we do list it in our guide to the best video streaming services for its growing sports coverage kid friendly Nickelodeon shows and original fare like Star Trek Strange New Worlds Showtime meanwhile has its share of shows and movies worth checking out from Yellowjackets to Billions to the recent Oscar winner Everything Everywhere All at Once This offer is set to run until June If you end up not digging the service remember to cancel

Swiss researchers use a wireless BCI to help a spinal injury patient walk more naturally |
https://www.engadget.com/swiss-researchers-help-a-spinal-injury-patient-to-walk-more-naturally-using-a-wireless-bci-151542965.html?src=rss

Swiss researchers use a wireless BCI to help a spinal injury patient walk more naturallyEver year more than a million people in North America suffer some form of spinal cord injury SCI with an annual cost of more than billion to treat and rehabilitate those patients The medical community has made incredible gains toward mitigating if not reversing the effects of paralysis in the last quarter century including advances in pharmacology stem cell technologies neuromodulation and external prosthetics Electrical stimulation of the spinal cord has already shown especially promising results in helping spinal injury patients rehabilitate improving not just extremity function but spasticity bladder and blood pressure control as well Now in a study published in Nature Tuesday SCI therapy startup Onward Medical announced that it has helped improve a formerly paraplegic man s walking gait through the use of an implanted brain computer interface BCI and novel “digital bridge that spans the gap where the spine was severed We ve been zapping paraplegic patients spines with low voltage jolts as part of their physical rehabilitation for years in a process known as Functional Electrical Stimulation FES Electrodes are placed directly over the nerves they re intended to incite externally bypassing their own disrupted neural pathways and when activated cause the nerves underneath to fire and their muscles contract Researchers have used this method to restore hand and arm motion in some patients the ability to stand and walk in others and for a lucky few exosuits The resulting limb motions however were decidedly ungraceful resulting in ponderous arm movements and walking gaits that more resembled shuffles Onward s earlier research into epidural electrical stimulation showed that it was effective at targeting nerves in the lower back that could be used to trigger leg muscles But the therapy at that time was hampered by the need for wearable motion sensors and by “the participants …limited ability to adapt leg movements to changing terrain and volitional demands “Onward addressed that issue in Tuesday s study by incorporating a “digital bridge to monitor the brain s command impulses and deliver them wirelessly and in real time to a stimulation pack implanted in the patient s lower back Clinicians have employed these systems for the better part of a decade to assist in improving upper extremity control and function following SCI Onward s own ARC EX system is designed to do just that though this study was the first to apply the same theories to the lower extremities Onward s patient was a year old man who had suffered an “incomplete cervical C C spinal cord injury a decade before and who had undergone a five month neurorehabilitation program with “targeted epidural electrical stimulation of the spinal cord in “This program enabled him to regain the ability to step with the help of a front wheel walker the research team noted in the Nature study “Despite continued use of the stimulation at home for approximately three years he had reached a neurological recovery plateau In addition to the EX Onward Medical has also developed an internally mounted electrostimulation therapy the ARC IM Per the company it is purpose built for placement along the spinal cord to stimulate the dorsal roots to help improve SCI patients blood pressure regulation The system used in Tuesday s study used the ARC IM as a base and married it to a WIMAGINE brain computer interface Onward MedicalThe Onward team had to first install the BCI inside the patient s skull Technically it was a pair of lead electrode implants each mounted in a milimenter circular shaped titanium case that sits flush with the skull The WIMAGINE “is less invasive than other options while offering sufficient resolution to drive walking Dave Marver OnwardMedical CEO told Engadget via email “It also has five year data that demonstrates stability in the clarity of signals produced Two external antennas sit on the scalp the first providing power to the implants via inductive coupling the second to shunt the signal to a portable base station for decoding and processing The processed signal is then beamed wirelessly to the ACTIVA RC implantable pulse generator sitting atop the patient s lumbar region where more implanted electrodes shock the appropriate nerve clusters to move their legs Together they form a Brain Spine Interface BSI system per Onward The entire setup is designed to be used independently by the patient The assistive walker houses all the BSI bits and pieces while a tactile feedback interface helps them correctly position the headset and calibrate the predictive algorithm In order to get the BCI and pulse generator to work together seamlessly Onward leveraged a “Aksenova Markov switching multilinear algorithm that linked ECoG signals to the control of epidural electrical stimulation parameters which seems so obvious in hindsight Basically this algorithm predicts two things the probability that the patient intends to move a specific joint based on the signals it s monitoring and both the amplitude and direction of that presumed intended movement Those predictions are then dumped into an analog controller which translates them into code commands that are in turn cycled to the pulse generator every milliseconds In all the latency between the patient thinking “I should walk over there and the system decoding those thoughts is just seconds Calibrating the system to the patient proved an equally quick process The patient had figured out how to properly “activate the muscles in their hips to generate enough torque to swing their legs within the first two minutes of trying ーand did it with percent accuracy Over the course of the rehabilitation the patient managed to achieve control over the movements of each joint in their leg hip knee and ankle with an average accuracy in that the BSI did what the patient intended of around percent “After only min of calibration the BSI supported continuous control over the activity of hip flexor muscles the team continued “which enabled the participant to achieve a fivefold increase in muscle activity compared to attempts without the BSI Unfortunately those gains were wiped away as soon as the BCI was turned off instantly losing the ability to step they explained “Walking resumed as soon as the BSI was turned back on It wasn t just that the patient was able to graduate from walking with a front wheeled frame walker to crutches thanks to this procedure their walking gait improved significantly as well “Compared to stimulation alone the BSI enabled walking with gait features that were markedly closer to those quantified in healthy individuals the Onward team wrote The patient was even able to use the system to cross unpaved terrain while on their crutches a feat that still routinely proves hazardous for many bipedal robots In all the patient underwent rehab sessions with the BCI a mix of standard physio rehab along with BCI enabled balance walking and movement exercises The patient saw moderate gains in their sensory light touch scores but a whopping point increase in their WISCI II scores WISCI II is the Walking Index for Spinal Cord Injury a point scale measuring a patient s ambulatory capacity ranging from “can move zero assistance down to “bed ridden “Onward s patient went from a to a with the help of this therapy “As the participant had previously reached a plateau of recovery after intensive rehabilitation using spinal cord stimulation alone it is reasonable to assume that the BSI triggered a reorganization of neuronal pathways that was responsible for the additional neurological recovery the Onward team wrote “These results suggest that establishing a continuous link between the brain and spinal cord promotes the reorganization of residual neuronal pathways that link these two regions under normal physiological While the results are promising much work has yet to be done The Onward team argues that future iterations will require “miniaturization of the base station computing unit and unnoticeable antennas faster data throughputs “versatile stimulation parameters direct wireless control from the wearable computing unit and “single low power integrated circuit embedding a neuromorphic processor with self calibration capability that autonomously translates cortical activity into updates of stimulation programs Despite the daunting technical challenges “the BCI system described in Tuesday s Nature publication may reach the market in five to seven years Marvel predicted It is possible and realistic that a BCI augmented spinal cord stimulation therapy will be on the market by the end of the decade This article originally appeared on Engadget at |
