Federated Ethereum Blockchains

Submitted by jbrown on Mon, 07/25/2016 - 07:32

In the aftermath of the DAO fork it occurred to me that there might be a better way for large Ethereum projects to exist on the Blockchain.

The idea is this: large projects should not use the main Ethereum or Ethereum Classic chains. Instead they should create their own independent blockchain specifically for their project. Smaller Ethereum projects could decide which of the Ethereum blockchains is the most appropriate to use. Which smart contracts do they need to integrate with most?

Storing compressed text in Ethereum transaction logs

Submitted by jbrown on Thu, 10/29/2015 - 08:31

There are a lot of good reasons to store blobs of text in Ethereum. For example, a decentralized Reddit clone could store all the messages in the blockchain. These messages would be uncensorable and archived for eternity. In theory IPFS could be used, but it does not guarantee the availability of the messages unless someone is actively storing them.

Using Dapple to test Solidity with Solidity

Submitted by jbrown on Tue, 10/20/2015 - 14:23

As the Ethereum eco-system is still very immature it can sometimes be very frustrating to develop on this platform. Gradually more tools are being developed that make it much easier, such as Browser Solidity.

Maker have released a new tool called Dapple. It's purpose is to provide a lot of scaffolding around dapp development. It comprises: package management, Solidity preprocessor (cog), Solidity testing, deployment and chain contexts.

Introducing Glofile

Submitted by jbrown on Fri, 09/18/2015 - 11:25

Glofile (Global profile) is essentially a clone of Gravatar for Ethereum.

Users of Ethereum will be accessing many different dapps with the same account. It makes sense that they should be able to associate some basic public information with their account that can then be utilized by any dapp.

Building a private blockchain on the Ethereum public blockchain

Submitted by jbrown on Fri, 08/14/2015 - 13:17

I first became aware of the concept of private blockchains several months ago when I watched a presentation by Preston Byrne of Iris Industries. Vitalik Buterin (inventor of Ethereum) was also presenting in that session, although not about private blockchains. I must admit I was very sceptical of the whole concept. The entire purpose of having a blockchain is so that no one can be prevented from putting a valid transaction on the ledger. With a private blockchain only an agreed list of people can create transactions. The problem, unlike on a public blockchain, is that it is very easy for a majority of participants to get together and prevent another from creating a transaction. The participants and the verifiers are the same people.

Drupal & Bitcoin

Almost everything we do on the web will work better with autonomous blockchain technologies such as Bitcoin & ethereum because they allow systems to be built with unbreakable rules. Unlike Facebook, Twitter, Airbnb, Uber, PayPal or eBay, no executive authority can step in and say the rules don't apply to you.

Of all the blockchain technologies, Bitcoin is currently the most high profile. It is a massive area of growth in the startup eco-system.
