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. More specifically, safe, robust and fast mobile applications, which can interact with blockchain technologies.

A successful blockchain implementation in the e-commerce space must bolster speed, safety and usability. It is always possible to improve consumer confidence as well as increase mainstream adoption by providing superior usability, safety and performance through smart design.
