the state of Ethereum - I am bearish on ETH, here are my reasons: 1. scaling Ethereum does not scale on the base-layer. One halfway popular dapp woulrd force the whole network to its knees, as seen with Cryptokitties or popular ICOs in the past. Ethereum as it is now, cannot handle even one single decentralized application that goes mainstream. The Ethereum blocksize has exceeded 1 TB and this is a very big issue. It is a known fact in blockchain technology that larger blocks centralize validators, and this is exactly what is happening here. There are fewer and fewer FAN-nodes (full archival nodes), and these nodes update the state of the Ethereum network. Because of Ethereum’s exponentially growing blocksize, the bottleneck is not regulated below these external factors and as such results in a shrinking and more centralized network due to network demands that increasingly exceed the average users hardware and bandwidth. Ethereum full nodes are getting fewer and fewer because the clients can't sync. And light nodes are not a full substitute of full node verification. This will lead to a weaker and more insecure network. Planned scaling solutions are Casper PoS, Sharding and Layer2 solution. - Proof of Stake is not as secure as Pow because the blockchain is not anchored in the outside world through the consumption of an external resource. In PoW this resource is Electricity, which makes sure that it is very very expensive to attack the blockchain and makes this attack economically unrewarding. Using energy burnt to back a block allows us to view immutability objectively. Whereas any non-energy-based method ultimately requires someone’s subjective interpretation of immutability. By attaching energy to a block, we give it “form”, allowing it to have real weight & consequences in the physical world. And PoS also leads to centralization as the power is concentrated with the people who have the most money. The entrance barrier to staking is 32 ETH, this is a fundamentally different system as PoW where miners compete throught the use of energy (cost) with each other. I personally consider Ethereum's economics broken at the base layer. look at this picture to see how centralized ETH gets with Pos: - Sharding comes from the world of databases and describes a technique where a database (or a blockchain) will be split in multiple parts (called "Shards") where each of the parts has a different area of task. Validating responsibilities are split up among various groups, each with their own shard. The intent is to relieve the amount of work a single validating node must do so there can be more of them, but it only results in prolonging the issue, and not fixing the problem. Furthermore, there’s now a huge cost for some of these nodes, as staking is required to be one of them. Sharding takes a single blockchain, turn it into multiple blockchains called Collations, then puts a twist tie on top and hopes mold doesn’t grow. Layer2 solutions are the only viable scaling solutions. For Ethereum we have Raiden and the Loom Network. Loom is especially promising as it enables sidechains on top of the Ethereum base-layer. BUT, if Ethereum adopts PoS (which is highly untested) we have an insecure base-layer. You can build a insecure second-layer on top of a secure base-layer, but not the other way round. Ethereums on-chain scaling solutions were delayed again this year. Casper PoS is now expected in 2019, sharding in 2020/21. issuance policy is another major negative point for Ethereum. The issuance of ETH is not capped! This means there is a constant flow of newly minted Ether, this goes on indifinitely in theorie. This makes Ethereum an inflationary asset, which is bad. use cases for Ethereum: the number one use-case is tokenization. And this used 99% for ICOs which create tokens with articificial demand and no real usage. This trend is declining and so i expect the price of ETH to decline. Tokenized securities and cryptocollectibles (ERC721) will be potential markets, but in my view they will get nowhere as big as e

expected by the public (but this topic is stuff for another article). Now we come to smart contracts, a clever idea but without the potential of mass adoption. here is why: - they are incredibly hard to write (see the Parity and the DAO hacks for example) - altough in computer science "code is law", smart contracts are NOT legally binding. They are NOT real contracts. Execution in a Turing-complete context is extremely tricky and hard to analyze. Securing a Turing-complete smart contract becomes the equivalent of proving that a computer program does not have bugs. We know this is very difficult, as nearly every computer program in existence has bugs. Consider that writing normal contracts takes years of study and a very hard bar exam to be able to write competently. Smart contracts require at least that level of competence and yet currently, many are written by newbies that don’t understand how secure it needs to be. This is very clear from the various contracts that have been shown to be flawed. And we have the "oracle problem", smart contracts rely on the correctness of outside data. Who feeds this data to the Ethereum system? What prevents these oracles to be corrupt or malicious? how do we prevent centralization? Blockchains have advantages in a very specific field, namely censorship-resistance and immutability. The killer use-case for this setup is Money. We do not need a decentralized internet. Because a centralized service is ALWAYS cheaper and more easy to use. Implementing a blockchain makes only sense in specific fields where immutability and the prevent of government control are important. I cannot imagine a future where everyone holds a Ethereum wallet with 345 different tokens for 345 specific services. And i highly doubt Ethereums capability to handle this kind of data load. Ethereum is not leaderless (Vitalik Buterin and dev-team), not entirely immutable (DAO-hack and subsequent fork because of transactions that were rolled back), not a Store-of-Value because of an uncapped supply and it does not scale on the base-layer. Another thing is that BTC increasingly cuts into Ethereums use-cases with Rootstock (smart contracts) and Drivechain (side chains). And with the death of dapps Ethereums second use case (capital rasising platform) also dies. This is the bearish case for Ethereum. Thank you for reading Blockchain Whispers (t.me/blockchainwhispers )

Als je denkt dat ether de vervanger van bitcoin "kan" of gaat worden zou ik me nog maar eens eerst gaan verdiepen wat bitcoin eigenlijk is en wat ethereum is/kan.

Hello, My question is why are there 2 currency's. 1 = ranked 41 on coinmarketcap npxs 2 = ranked 1504 on coinmarketcap npxsnem. And what is the diffrence between the tokens. And last but not least. What do i need to do to have a xpass card and where can i pay with it for now. Thank you in advance

▪ NPXSXEM is a NEM mosaic token created via Pundi X’s commitment to utilize NEM blockchain technology to produce 20,000 of the world’s first NEM-based Point-of-Sales terminals, called NEM XPOS. ▪ NPXS has the same utility as the NPXSXEM, the only difference is that NPXS is an erc20 token (stored into an ethereum adress) and NPXSXEM is a NEM mosaic token (stored into a nem adress) ▪ NPXS has a much higher supply (around 280 bil) than NPXSXEM (9 bil) ▪ Those 20,000 nem xpos are going to be deployed till December 2020. While the goal for the nem xpos is 20,000 units, the xpos has the goal of up to 700,000 units deploted till December 2020

Kosten zijn een percentage van de transactie. Met het huidige pinsysteem betaald de winkelier per transactie aan de bank. (Afhankelijk van de winkel maar al gauw 5 cent per transactie) Het mooie is dus ook dat als er door de winkel bitcoin wordt verkocht aan de klant, de transactiekosten laag zijn en de klant goedkoper bitcoin of ethereum kan kopen dan websites als bijvoorbeeld anycoindirect of btcdirect.

Even een update voor iedereen:Wij gebruiken nu een maand de Xpos in onze winkel en langzaam aan gaat het de goede kant op.Buiten het feit dat wij crypto accepteren als betaling via de Xpos, verkopen wij ook BTC, Ethereum, BNB en uiteraard Npxs via de Xpos. Dit is te kopen met cash geld of met pin (maestro). Het gaat gemakkelijk en snel als je een Xwallet heb of een Xpass.Transacties gaan snel en hebben lage kosten. Wij wachten nu op verdere ontwikkelingen, vooral op de update van de Xpos dat we Visa en Mastercard betalingen kunnen accepteren met de Xpos.Mocht u crypto willen kopen, of willen weten hoe het allemaal in z'n werking gaat, kom gerust langs bij ons in Amsterdam.

What are the relationships between the f(x) coin, NPXS, and NPXSXEM? NPXS and NPXSXEM are tokens designed to be utilized in the Pundi X point-of-sale network, including the purchase of XPOS devices, XPASS cards, payment for crypto transaction fees, token listing fees, app listing fees and advertisements on the XPOS. The f(x) coin will be used for facilitating all operations in the Function X ecosystem and blockchain as a native coin. Current and future Pundi X products will migrate to Function X and hence will use f(x) coin as the native coin instead of Ethereum or NEM.

Think of fx as ethereum. And npxs is a token on fx with the same and more utility in the future as the payment coin for payments

vraagje, ik krijg fx gestort op mijn enjin wallet. maar dat komt gewoon binnen als ethereum!nu heb ik de ook het gevraagde aantal ether terug naar het gevraagde adres gestuurd!maar na 8 uur wachten zegt mijn xwallet nog steeds nog geen bevestiging!

Ik zie fx straks net als ETH is voor het ethereum netwerk. Fx is straks op zo'n eigen blockchain. Als PundiX groot gaat worden en er komen veel nodes, dan kan je denk ik niet meer om fx heen als je in PundiX geloofd. Dus voor mij is het een investering in de toekomst.

Zoek je bij bitcoin of ethereum? Niet bij usd market. Misschien een beetje naar beneden scrollen
