For now I decided to focus on such a solution, which will fit to majority of miners and do some extensions later. In this chapter I expect that you're familiar with this protocol and you understand terms like "request", "response" and "notification". For high level image of the Stratum protocol concept, please read Stratum protocol specification on Google docs. This document needs some care, but give you the basic examples how to connect to Stratum server.

Traceback may contain additional information for debugging errors. Now let authorize some workers. You can authorize as many workers as you wish and at any time during the session. In this way, you can handle big basement of independent mining rigs just by one Stratum connection. Small engineering note: There's a good reason why first job is not included directly in subscription response - miner will need to handle one response type in two different way; firstly as a subscription response and then as a standalone notification.

Now we finally have some interesting stuff here! I'll descibe every field of the notification in the particular order:. Just be absolutely sure that your extranonce2 generator always produces extranonce2 with correct length! That's all! For following calculations we have to produce double-sha hash of given coinbase. In following snippets I'm using Python, but I'm sure you'll understand the concept even if you're a rubyist!

It is as simple as:. Following Python snippet will generate merkle root for you. Now we're almost done! We have to put all together to produce block header for hashing:. If you're a miner developer, you already have util methods there for doing it. For some example in Python see Stratum mining proxy source codes. When miner find the job which meets requested difficulty, it can submit share to the server:. For all current getwork-compatible miners you can use Stratum mining proxy running locally on your mining computer.

One mining proxy can handle almost unlimited number of connected workers, so running one proxy for all of your mining rigs is a way to go. If you want support of Stratum protocol in your miner, just ask its developer and show him this page. Also don't hesitate to contact me and ask for implementation details. We apologize but this page has not yet been translated to your language.

Stratum V1 Docs. Why to Change Something That Works? Long Polling: An Anti-Pattern Getwork came as an easy solution for building standalone miners do you remember when the official Bitcoin client was the only miner? Now we know what's wrong in the current situation, so let's design a new protocol and don't repeat bad decisions again: Stratum Protocol I originally designed Stratum protocol for lightweight Bitcoin client called Electrum.

Block header that string what is in getwork response and what miners are hashing is composed from following parts: Block version, nbits, hash of previous block in the blockchain and some padding bytes, which are constants. Nonce and ntime, which miner can modify already. Merkle root hash, which is created by hashing of bitcoin transactions included in the particular mining job. All bitcoin miners already have JSON libraries included.

JSON has native support in almost every language. In contrary of most binary protocol, JSON payload can be easily extended without breaking backward compatibility. We don't need to reinvent a wheel. Why I throw away other serializers: Custom text protocol is human readable and easy to debug, but not so easy to implement as it may look at first glance. We have to define a way how to pair request and response, because sequential processing of requests may be a bit tricky on some platforms yes, now I'm referring Twisted framework which I used for pool implementation.

We also have to define how to serialize various data types like lists or even mappings. JSON solve all this transparently for us. Custom binary protocol is the most compact form which can saves a lot of bandwith, especially while dealing with binary data involved in bitcoin mining.

I wanted the protocol which is easy to implement. Fiddling with byte order and binary headers is not what I was looking for. Thrift is another binary protocol which I used some time ago, but it is defitely too heavy for our purposes. Stratum Versus Getblocktemplate Getblocktemplate introduced in bitcoind 0. There are still some reasons why Stratum is, in my opinion, a better solution for pooled mining: It is less complex, much easier to implement in existing miners and it still does the job perfectly.

For historical reasons getblocktemplate still uses HTTP protocol and long polling mechanism. I described above why this fails on large scale mining. Checking submitted shares is also much cheaper on processing resources in Stratum than in getblocktemplate. The best part about PhoenixMiner is its 0. This miner works exclusively with AMD graphics cards. So, if you root for team red, this is one of the best miners you can install on your system for mining Ethereum.

Dev fee for the Ethash algorithm depends on which GPU you have. It's set to 0. TeamRedMiner may not be as fast as PhoenixMiner, but on the upside, you don't get rejected shares nearly as much. Of course, you can mix and match AMD graphics cards from different generations in your mining rig. For example, you can use the KawPow algorithm to mine a cryptocurrency called Ravencoin. Hence, this miner will still be relevant when Ethereum goes Proof-of-stake.

If there's one miner in this list that can match PhoenixMiner when it comes to fees, it's GMiner. You can mine Ethereum with a mere 0. Hence, you don't have to look for a new miner again when Ethereum goes Proof-of-stake and kills mining. However, the good news is that most NVIDIA graphics cards are compatible as well, but the mining speed and stability will vary depending on the exact GPU model you have.

The developers behind LolMiner do a good job at pushing out software updates. Developers update their mining programs regularly, and hence, the best miners may vary with time. Sure, T-Rex and PhoenixMiner may be the fastest options at the moment, but a new program could take the crown within weeks. Regardless, all the Ethereum miners listed here have earned quite a reputation for their performance and stability in the last year or two.

It makes sense that permanent data, like mined transactions, and ephemeral data, like account balances, should be stored separately. Ethereum uses trie data structures to manage data. The record-keeping for Ethereum is just like that in a bank.

The bank tracks how much money each debit card has, and when we need to spend money, the bank checks its record to make sure we have enough balance before approving the transaction. An incrementing nonce can be implemented to counteract this type of attack. In Ethereum, every account has a public viewable nonce and every time a transaction is made, the nonce is increased by one. This can prevent the same transaction being submitted more than once. Note, this nonce is different from the Ethereum proof of work nonce, which is a random value.

Like most things in computer architecture, both models have trade-offs. Some blockchains, notably Hyperledger, adopt UTXO because they can benefit from the innovation derived from the Bitcoin blockchain. We will look into more technologies that are built on top of these two record-keeping models.

The state trie contains a key and value pair for every account which exists on the Ethereum network. A storage trie is where all of the contract data lives. Each Ethereum account has its own storage trie. Each Ethereum block has its own separate transaction trie. A block contains many transactions. The order of the transactions in a block are of course decided by the miner who assembles the block.

The path to a specific transaction in the transaction trie, is via the RLP encoding of the index of where the transaction sits in the block. Mined blocks are never updated; the position of the transaction in a block is never changed. The main Ethereum clients use two different database software solutions to store their tries. Rocksdb is out of scope for this post. LevelDB is an open source Google key-value storage library which provides, amongst other things, forward and backward iterations over data, ordered mapping from string keys to string values, custom comparison functions and automatic compression.

Whilst Snappy does not aim for maximum compression, it aims for very high speeds. Leveldb is an important storage and retrieval mechanism which manages the state of the Ethereum network. As such, leveldb is a dependency for the most popular Ethereum clients nodes such as go-ethereum, cpp-ethereum and pyethereum.

To learn more, we have to access the data in leveldb using the appropriate Patricia trie libraries. To do this we will need an Ethereum installation. Here is a easy to follow tutorial for setting up your own Ethereum private network. We will provide our code examples and screen captures from our Ethereum private network. As we mentioned previously there are many Merkle Patricia Tries referenced in each block within the Ethereum blockchain:.

To reference a particular Merkle Patricia Trie in a particular block we need to obtain its root hash, as a reference. The following commands allow us to obtain the root hashes of the state, transaction and receipt tries in the genesis block. Note: If you would like the root hashes of the latest block instead of the genesis block , please use the following command. The following commands will further prepare our environment. From this point, running the following code will print a list of the Ethereum account keys which are stored in the state root of your Ethereum private network.

You will have noticed that querying leveldb returns encoded results. In short, Ethereum have extended on the trie data structures. The following example uses ethereumjs. The ethereumjs repositories are easy to install and use; they will be perfect for us to quickly peer into Ethereum leveldb database. This clever upfront design has many advantages.

Given that mobile devices and Internet of Things IoT devices are now ubiquitous, the future of e-commerce depends on safe, robust and fast mobile applications. As we acknowledge advances in mobility, we also acknowledge that the constant increase in blockchain size is inevitable.

It is not practicable to store entire blockchains on everyday mobile devices. Every function put, update and delete performed on a trie in Ethereum utilizes a deterministic cryptographic hash. This cryptographic feature provides an opportunity for light clients devices which do not store the entire blockchain to quickly and reliably query the blockchain i. An interesting idea, mentioned in the Ethereum white paper is the notion of a savings account.

You may recall our discussion about bitcoin UTXOs at the start of this article. UTXOs are blind to blockchain data, and as we discussed, the bitcoin blockchain does not actually store a users account balance. For this reason the base protocol layer of bitcoin is far less likely or perhaps unable to implement any sort of daily spend limits. As work continues in this space we will see a lot of development in light clients.
