Ethereum - the goblin of memory.

I was doing a lot of Research and Development recently and I was trying to figure out why it is taking so long to update my block chain on Ethereum Network.

Apparently, every time I launch my geth sync mode, it hangs... and I really hate it.
Turns out, the laptop cannot take the amount of data to be pooled into it plug the whole database needs to be launched into the memory bank.

I used this command to launch the synchronization process
geth --cache=2048 --rpc --nat extip:35.185.184.162 --pprof --v5disc
where the cache is set to 2GB and ext IP is because my network is firewalled pass thru, but in itself, that is the direct IP address, useful for VPS or Google Cloud Compute.

Do note the whole stack (3,888,903 blocks as of 17 June 17) takes 24GB of space in the hard drive and it takes AGES to synchronise unless you have extreme fast internet, and SSD hard drive.

Of course it is faster if you could do an offline download.. and yeah.. I would be happy to do so, for a small fee. Just send some ether (0.01 will do) to my wallet (0x162c28e126a97d0009158fbda0ca93e6e9cc13d0) to cover the network fees and drop me a note on my facebook (@azrin619) that it's done... with your gmail address so you can access it.

If you do not believe how much the goblin took from me.. see this

I set 2vCPU with 8GB Ram and it went over the limit.
Just a warning.

Friendly Exchanges for Malaysian

We did our research and many of the exchanges do not like Malaysians at all. This is due to the International KYC Rules.

We tried out CEX.IO  over the weekend and well, our deposits were fast credited.

Buy Bitcoins with Credit Card

Full Disclaimer:
You will need your passport and license to verify.
DO NOT USE A DEBIT CARD as it will fail. We tested with Maybank and other major ones, it craps out. The banks 3DS system screws up the Secured by Mastercard system.
The card need to have full embossment and 2FA done.
I opted for PHONE CALL IN to do my 2FA instead of SMS as it does not arrive. Unless you use Google Authenticator, which we do not prefer,.

So you do your registration, send yourself (by EMail) the images of card front, back , selfie with yourself, Driving License, Back of License, Selfie with License using your HANDPHONE and download to your local PC. Saves you the hussle of using your webcam which is crap anyway.

Buy-in cost about 3.5% + $1.00 or so.
They allow USD300 a day or $1000 a month. They do take a while to do full verification.

Withdrawal of funds is quite fast actually, depending on your bank.I used MaybankSG and it was credited within few mins of being approved.
They have a $4 FastCard fee and a $20 withdrawal minimum.

Honestly.. unless you trade quite a bit.. then it will be worth it.

How Safe is our storage?

You may think we have poor security but in essence, we are very Kiasu. Digital Robbers are very cunning so we know what we are doing.

Only a small amount of ETH and BTC is stored in our HOT WALLETS. The rest are broken apart into COLD FREEZE, ie where the Private Keys are stored offsite. Physically and Digitally.
Although our systems are facing the world without any firewall, that is what it is meant to do. Your data is stored in Google Cloud Compute across multiple networks. Internally, its stored across Cold Buckets, encrypted using standard 4196Bit keys, and add to our Kiasuness, we use Storj Community Crowd-Cloud storage, meaning, the data is spread across so many persons, like torrent but secured.

If your digital money exceeds the float allowed, it will be batched off to the cold store. Exceed the cold store, we send to Freezer to ensure it is not taken out.

Your BTC-----[Our HotWallets]++++++++[COLD STORE]===========(FREEZER)

Because we also run a mining pool, our hot wallets are 25BTC max, or about USD60K. We use Coinbase and other exchangers to keep the pool.

As some transactions exceed our base limits, we at Zyraz Technology prefer SGD as basis but we take Ringgit Deposits to our Personal Accounts. We have bank accounts with AMBANK and AL-RAJHI but business banking in Malaysia is somewhat very much lagging... so we do not trust banks.. just like you do. We take deposits via PAYPAL. Secured.

So we are good... if we do get robbed... it may be from a friend... as our connections are Gigabyte GBE Fiber internet...
