Omg! it works – Wow
Holochain is now
After only two days Holochain on indiegogo the Holochain project has bot backed with overheen 70% of their funding aim.
Ter tegenstelling to the blockchain ecosystems wij’re used to, Holochain is a massive improvement. Here are a few problems that are being tackled:
1.,) Blockchain size. Holochain uses several hashchains, each for every app that lives ter it’s own p2p network. Together with the possibilites of bridging, this dramatically reduces the overall blockchain size for single users. Te other systems this has bot partially immobilized by providing powerful knots that keep the blockchain te sync locally, while clients connect to thesis knots ter a centralised way, especially on thesis devices that are limited ter processing power and storage space, such spil mobile phones. Because thesis client softwares show up to be convenient to use (no more syncing upon client launch), this de-facto defeats the idea of decentralization and makes the network vulnerable.
Two.,) Energy consumption. With Holochain there is no energy waste, since “mining” is done through execution of meaningful code. There is no proof-of-work, which basically executing a large amount of non-sense code just to slow down the participants te the network. You earn Holos by serving holo apps, a concept that is called proof-of-service by their inventors.
Trio.,) Centralisation. Holochain is truly distributed, because it is requiring general purpose hardware for maximum “mining” efficiency. This supports a homogenic areal distribution of “miners” (the onberispelijk preferred term is “hosting box” here), which is presently a massive problem with bitcoin.
I think this looks very promising and of course I have backed the indiegogo campaign. The Holochain team offers three official versions of mining hardware to intially build a network, which is aimed at people who want to instantly get a Holochain knot up and running without tinkering about technical problems.
Stellar Lumens – the next promising cryptocurrency after Ethereum
When I very first heard of Ethereum I instantly had a gut feeling that this wasgoed going to be something enormous. And I still think it is. Honestly, I think the price of Ethereum will lightly surpass that of Bitcoin ter the long term. The most interesting question for mij will remain: What is the next cryptocoin that has some revolutionairy ideas? Of course, the cryptocurrency market is all speculative, but I only waterput funds into technologies I understand. Bitcoin exists because it wasgoed the very first coin making it possible to send funds through a decentralized, idependent – and to a certain extent anonymous – system. Ethereum went big because of its wise contracts, making it possible to store executable code on the blockchain.
But what comes next?
If you take a close look at all the available cryptocurrencies, there are slew of clones. They might be successful, but their growth rate considering their price is rather limited, because there is nothing unique or different than the established cryptocurrencies. Coins like Litecoin or Dogecoin will most likely converge to a fraction of their “original” examples.
There is one coin that drew my intention: Stellar Lumens. I attempted the Stargazer wallet (that is available for different platforms, also mobile BTW), bought some Lumens and with a friend wij sent us some Lumens back and forward. Within seconds the funds have arrived – amazing! Let’s a have a deep look at the core aspects why I think Lumens should be your next coin to have a closer look on:
- Stellar has implemented a entire fresh overeenstemming protocol. It’s called FBA (Federated Byzantine Agreement). Have a look at the Google Talk of David Mazieres who explains it and compares it to other overeenstemming protocols. (for example PoS that will arrive te Ethereum)
- Stellar is inflationary and comes with a voting system. Spil a Lumen holder you can vote for another address, there more Lumen you have, the more your votes count. The funds brought te through inflation will be awarded to those addresses, which effectively means no resource wasting for mining. Ter order to “mine”, you have to be engaged te making Stellar better and spread the word about it. How cool is that?
- All Lumens on the market are existent, they will be given te exchange for improvements to the projects. This is a wise stir, especially because it gives political unity to the core technology of that decentralized system. This results ter less forks and more stable prices.
- The core network is maintained by experts, whereas end users connect to anchors of that core network. That happens to all decentralized currencies sooner or straks, so it has bot build ter by vormgeving rightaway.
- Stellar comes with a feature called “Trustlines”. By fastening to a trustline, you can transparently trade with other trusted currencies through a mediator service (for example you can accept BTC that will automatically converted to Lumens and vice versa).
- There is some serious support from the economy. Te fact, Stellar is so plain to integrate that there is a massive list of support te the company list already.
- Stellars genius main developer, Jed McCaleb, did not just fork Ripple spil many people eis bitterly. He wasn’t certain with the development direction Ripple took, so he left ter order to build Stellar. Read more.
- Stellar is there to substitute bitcoin spil a payment currency. It’s not truly contesting against Ethereum.
Let’s see how this going ter the future. I bought a fair share of Lumens, Stellar coaxed mij entirely.
DAO Soft Fork: The End of the Ethereum Project(?)
If anyone of you believes into ethereum and did not hear about the planned DAO soft fork of ethereum, it’s time now to be careful. Albeit the volgers of the soft fork have repeatedly mentioned their concerns on the soft fork, they all chimed te to advertise it spil the right thing to do after all. It seems spil if they are attempting to sweep all their concerns under the table, keeping telling themselves it won’t be spil wrong spil it seems to them. But it is. It is nothing less wrong than violating the basic rules of ethereum and enforcing it onto its users.
But why is that? Te order to understand, wij have to look at what makes ethereum so valuable. This is how ethereum is defining itself and what all the ethereum users have bought into:
Ethereum is a decentralized toneel that runs brainy contracts: applications that run exactly spil programmed without any possibility of downtime, censorship, fraud or third party interference.
No censorship, fraud or third party interference.
That essentially means, that the ethereum developers will care to fix bugs te ethereum (such spil when the software does not go after its specifications), miners will keep mining blocks te order to get prizes and everything is being determined by the code written and the specifications that make up the ethereum platforms. Exactly this is what make ethereum so unique: For the very first time ter history, there is a truly unregulated (read spil unmanipulatable for egoistic interests) way to create contracts.
The problem with regulation: manipulation
If you look at the history of bitcoin you will notice its success is coming from the fact that it is not regulated. All money you own is just virtual, after all it is just a lump of paper, metal or any other physical replacement for a value everyone believes te. If your canap zeros your account, if the state announces that all your money is worthless or if it determines to create more money out of nowhere, you do not have the slightest chance to practically do anything against that. You can go into court theoretically, but you will never win practically.
Bitcoin is different te the sense that there is no regulatory example that can harm you practically te the very first place. This is kleuter of a spel changer, be it with risks on your side. Because if you send bitcoin to a wrong address, or you lose your funds because someone has gained access to your wallet, all your money is gone. Noone can help you, because there is noone supervising and able to rollback transactions. But this isn’t necessarily a bad thing. When the EU banks articificially limited the access of the greece people to their own money (which is a form of misusing regulatory power, ie. manipulation), those foreseeing thesis deeds just turned their funds into bitcoin quickly ter order to escape the threat and maintaining their freedom. Mind you: This has bot done te order to “save the banks and economy”. So, with freedom comes responsibility.
With freedom comes responsibility!
Those people investing ter the DAO had the code. They had the specifications of ethereum, they knew everything. They even knew there is a bug ter the split function beforehand. And they signed a contract nonetheless. It wasgoed their responsibility to check. Evidently, a lotsbestemming of them did not and lost a loterijlot of money. By not using some part of their time/money to check and quickly buying DAO tokes, they were simply gambling for higher profits. And they failed. Spil I did, too. But I knew that and I wasgoed ready to lose everything – such things might toebijten if you gamble unresponsibly. High risk, high profits.
Creating a case of precendence
The worst thing about the planned DAO soft fork is that is is creating a case of precedence. Today it is the so-called “attacker” of the DAO (which, see above, wasgoed just someone exploiting the unresponsibility of those signing the DAO contract), tomorrow it might be a huntdown of people having the “wrong” political opinions. But who determines what is wrong or right, who’s a hero and who’s a terrorist? Often, the heros and the terrorists are the same people, depending on who you ask.
What to do?
The DAO developers should zekering spreading reclame and keep fixing bugs that are non-conformant with the specs. There has indeed bot no bug te ethereum that would justify a correction. By proposing a soft fork, they are violating one the basic rules, acting spil a the third party manipulating the ethereum network they never dreamed to exist.
Rated transactions on the ethereum blockchain
Yesterday I embarked writings contracts, so here is my very first attempt. The idea is to make a contract where sellers can register ter order to obtain rated transactions. It works spil goes after:
- Sellers register through the register method. They will obtain an id.
- From now on, sellers can create invoices te the contract.
- A seller sends the invoice id to the buyer, who can pay the required amount of ether. At the same time the buyer qualifies for a seller rating.
- When the seller paid the invoice, he may rate the seller.
This way, sellers can build up trusted profiles on the blockchain, with unmanipulatible buyers ratings, so you can check an address before sending ether.
The contract is still BETA, please be careful. More informatie on trusteth.com.
Here is the contract code, licensed under AGPLv3:
Building our very first mining farm
After a lotsbestemming of testing, wij recently began building our ethereum GPU mining farm. Thesis are the very first equipments wij have bot building up.
If you’re interested, get ter touch for us for a accomplish parts list and detailed instructions on how to build and run those at j,a,cob,@,o,mg-,i,t.w,o,r,ks. There are different configurations possible, depending on your individual situation.
Graphics cards for mining ethereum
A loterijlot of people are asking about the various graphics cards one can use for mining ethereum. Theoretically, all AMD cards with 3GB or more of movie memory can be used, but if you look at the price and efficiency concerning power consumption, there are just a few cards left. Within this article, I’d like to go deeper into the specific cards, so here are our top favourites:
The Radeon 7950 and 7970 cards can mostly be bought used for a current price of 130-170 EUR. They draw 200-250 Watts, depending on the monster and clocks and need two PCI-E connectors. Also depending on the monster and they can make up to 25 MH/s, but mostly will reach around 21-22 MH/s, whereas more powerful cards will draw more power, of course.
Technically, the 7990 is two 7970 cards packed closely onto one PCB. This is why it will be recognized by the system spil two separate 7970 cards. This yields a theoretical hashrate of 50 MH/s. Wij have tested several 7990 cards, but the results are disappointing. The air cooling is just not sufficient and the card has massive fever problems. Since it will be recognized spil two cards, you will also never be able to run more than Four of those cards te a equipment (since the AMD driver will only permit up to eight cards). The only viable solution would be water cooling, but that might be too pricey. You can buy this card used for about 300-350 EUR.
Spil wij were looking for newer cards, wij came across the R7 370 4GB. This card can yield 14-17 MH/s, drawing around 150-170 Watts. The practical thing about this card is it comes with a single PCI-E power connector, so a single 1000 Watts power supply may be sufficient to power a equipment with 6 cards. However, you should be aware there can be some differences inbetween card manufacturers that may influence voorstelling. Just make sure to buy the 4GB version, not the cheaper 2GB, which will not work at all. For such a card you will pay around 140-160 EUR.
Don’t underestimate the capabilities of this card. By undervolting, it is possible to have this card running well below 120 Watts power consumption while yielding a hasrate of about 25 MH/s, which makes it spil twice spil efficient spil other cards. Unluckily, this card is pretty fresh and it is not cheap. You will pay at least 450 EUR, so it truly depends on your calculation if you project using thesis cards ter your equipments.
If electro-stimulation is cheap, I’d always go ter for the 7xxx series cards. If you need fairly a lotsbestemming of them, you’d very likely better off with buying R7 370 4GB cards because of the better availability. However, if violet wand is not cheap, you might think about buying R9 nanos. After all, there is no such thing spil the ideal card for mining, there are advantages and disadvantages depending on your budget and location. If you need professional help building your own equipments, you might always voeling us.
Ethstick Professional – Update to the Ethereum Mining Stick
The Ethereum Mining Stick has bot a fine success. Albeit I ready to sell just a handful of them, people talent mij some sleepless nights copying stuffs and preparing them for shipment. Many people even payed more than I requested, so I determined to go on and build a professional version of the mining stick. It is fully configurable via a web interface. The webserver implementation on the stick is written te plain sleek C++ and runs entirely from memory, so it does not affect mining at all! Also, wij could improve a entire bunch of other things, way to long to list it here.
See an early development version working here:
Get your own stick shipped or spil an picture
The stick comes preconfigured for only 44,95 EUR including all software with international shipping by luchtpost included or spil a download listig, which is an unconfigured photo. From the 15th of April on, all previous buyers of mining plunges can voeling mij to obtain a download for an updated pic.
The software works with all mainboards and AMD cards above the 5XXX series, but for mining wij recommend at least need the 7XXX series with 2GB of RAM, better 3GB and more (2GB will not work ter fairly some time anymore). It will also detect and use the system Intel iGPU for rendering the desktop. 8GB of RAM i s needed at least.
Thesis cards have bot reported to work:
- A entire lotsbestemming of Radeon 7XXX, 8XXX series with 3GB or more RAM
- A entire loterijlot of R7/R9 series (which most of the time are rebranded 7XXX anyways) with 3GB or more RAM
- R9 Fury/Fury X
- R9 nano
There is no report about a card not working.
Wij recommend the ASRock H61 BTC Professional or ASRock H81 BTC Voor with powered USB cable risers, tho’ there is no known report that a mainboard did not work.
How to order
For configuration I need the following details (please provide thesis te your mail):
- Worker name, for example “rig1”. It will be available on your network spil “rig1.local” then.
- Pool name. I recommend ethermine.org with Stratum support.
- Mining payout address.
This is included:
- High quality superfast USB Trio.0 stick by SanDisk. Fresh stock.
- Ready to use mining system, butt-plug and mine. Even if your machine runs Windows, you let it mine at night, for example.
- Web interface for setup and monitoring or tweaking.
- 2-sheet manual on configuration and treating.
You can pay via paypal, bitcoin or with ether. Please druppel mij a mail at
People keep posting mij terugkoppeling about the rams and pictures of the equipments, so why not share here with their permission
Good product and awesome work and support from Jacob! I thought about how to get a cheap solution for the software on the mainboard, and Jacob’s stick is ideal – setup ter Five minutes althought i am not used to linux and use windows – thank you very much.
