Announcing MyEtherWallet v3.24.00: Difficulty Bomb&Updating blockchain

Due to the complexity of the Bomb and the increased risk of hacking, we pushed a rather drastic update that implements a number of changes and improvements, including enhancement of efficiency and scalability of the blockchain, acceleration of transaction speed, and additional security in the form new formats private keys which will help protect users against hacking.
If you are using private key or UTC, then you need to go into the wallet and update manually, otherwise they risk being unprotected.

How do i update my Ethereum wallet?

1. Go to our website /]MyEtherWallet.com
2. Unlock your wallet using your Keystore File (UTC / JSON) or simply use your private key.
3. Click Unlock and wait for the update.

Please note that you need to manually update your wallet, failure to do so may result in funds being lost.

We are taking these measures to protect both you and our network from phishing and malicious attacks.

Thank you for your cooperation and understanding!
MyEtherWallet Security Team.

See this is what I was thinking. Since "Cloud" has been the big buzzword for years now and everyone has all of their products "cloud ready/enabled/integrated/marketing BS" I assumed this is the next logical step of this continued BS by now "blockchaining" all their stupid products..

Neither the specs for the DDR4 SO-DIMM memory bandwidth nor the INT32 TOPS for the Zynq series would appear to support the claimed 21 MH/s ETH hashrate, either via direct DAG sampling or via light-DAG based full entry on-the-fly generation.

How else do you see their specs attaining 21 MH/s in ETH ?

A technical specification of this router looks good. It can achieve such a speed. But I’m not sure in such power consumption.

If something sounds too good to be true it ussually isn't. If they were really onto something that big they would keep it to themselves and make millions from mining.

For legal reasons they wouldn't do that.

However if you think about it, it would be great because it would make ETH very decentralized if it was in many thousands of households like that.

So if the customer would get some $ off for their electrical bill, it would be a win/win for everybody.

Watch a few months from now Charter and Comcast both start telling their customers they need to upgrade to their new all in one modem / router.  And inside is an FPGA which your ISP uses to mine crypto while you float the power bill, and all without ever telling you.

The claimed hashrate isn't supported by the available bandwidth of the memory they're using. Their design shows they are using dual DDR4 SO-DIMMs, so if we assume they are using the fastest SO-DIMMs available (eg. GSkill displayed their fastest kits at Computex 2018: DDR4-4200 SO-DIMMs, http://www.gskill.com/en/press/view/g-skill-showcases-extreme-ddr4-memory-kits-up-to-ddr4-5066mhz-at-computex-2018 ), then this "router-miner" design would have a 128-bit wide memory bus (ie. dual 64-bit bus SO-DIMMs) at 4.2 GHz data pin speeds. This would give them an effective bandwidth of around 67.2 GB/s.

Since a single ETH hash samples 8192 bytes from the DAG (ie. 64-iteration loop of 128 bytes per iteration), then the 67.2 GB/s bandwidth would give a theoretical, zero-latency hashrate of around ~8.2 MH/s. Pretty far off from the claimed 21 MH/s.

The alternative approach of storing just the much smaller light-DAG in the FPGA block RAM and generating the full DAG entries during the ETH sampling loop by brute-force/"on-the-fly" would require around ~11 INT32 TOP/s processing capability (ie. 256K FNV operations or equivalently 512K INT32 operations per ETH hash) for the claimed 21 MH/s hashrate. The FPGA series they are using (Zynq Ultrascale+, https://www.xilinx.com/support/documentation/selection-guides/zynq-ultrascale-plus-product-selection-guide.pdf ) has at most around 1.1M logic cells and 1.9K DSP slices. By comparison, the much larger Virtex Ultrascale+ VU9P (as used on the VCU1525 and the mining BCU1525 card) has 2.5M logic cells and 6.8K DSP slices and is rated at around ~5.3 INT32 TOP/s (https://www.xilinx.com/support/documentation/selection-guides/ultrascale-plus-fpga-product-selection-guide.pdf ). Still under the ~11 INT32 TOP/s needed to brute-force DAG entry generation "on-the-fly".

So whether via DAG sampling from the DDR4-SODIMM, or alternatively via brute-force DAG entry generation, it would seem that this "miner-router" doesn't have the specs to do 21 MH/s for ETH.

Yeah i believe this is fake. I tried going over their website again and I can't even find a simple user manual or instructions on how to "install" or "setup" the physical router. If they had a real product this user manual document would have been a minimum requirement for any product. Seeing that there is none may be indication that there is no real physical product.

Be warned of scam.

Its a fake, even bitmain cant realize good dagger hashimoto asic miner with high effiency.

It does not instill confidence in me to read a page on the assembly process of a product and see simple mistakes such as not knowing what type of connector is on the theoard.

What the fuck is up with every goddamn project not even having an editor that is capable of seeing simplistic errors such as this?



And this shot of mister "I'll pump you up" does not instill any confidence.

It could open the door for a whole line of dual-function household items that mine. Many would pay a decent premium for a coffee maker that mined zcash, for instance.

Amazing how this product talks a good game, but as i and most of the other people i know come from non-technical non-computer engineering background, we will probably never be able to verify this until there is an actual product being reviewed on the market.

Hopefully some of the vets here can get their hands on an actual product and post some reviews.

The design looks very cool. And it's using a Quad-Core ARM Cortex-A53 (1.5Ghz), and a Dual-Core ARM Cortex-R5 (600 MHz) and 1 ARM Mali™-400 MP2, and very nice config with 2x DDR4 SODIMM 4-8GB, but 21 Mh/s is very powerful. It's almost the same with a Gtx 1060, and I think 18 Watts is too good to be true for these programmable logic chips. If its the case, I think Bitmain could make a move very quick with a powerful Asics miner for ETH.

The price will confirm everything.

The Xilinx Zynq UltraScale+ mentioned is nearly £5K for the chip alone if you google for a price

From the description it pretty much says they are combining two units into one to make this work. Why put this into a router and not just sell the mining portion as a stand-alone unit?

While I am fine with mining, I don't want anything on my router securing the rest of my network except what is required to run the router. There are already enough back-doors and security vulnerabilities to worry about without intentionally placing more of them in your router.

Router with 4Gb ram ? how to store dag file ?

They seem to be using one of Xilinx UltraScale devices.

Each of the DSPslice in the device seem to be like bitslice.  They say they're going into production.  It would be great to get my hands on an actual unit.  I'd like to play with one.

As far as the ROI they present, well, they haven't figured the difficulties rising so fast.

seems feasible, 1050ti 4g can get 15M/s on ethash
but I cannot find the price and release date
