I downloaded Mist-win64-0-8-7.exe and had Mist 0.8.7 running on Windows 64 bit 8.1. Then a few days later I tried opening it and got this message: Couldn’t connect to node? See the logs for more: Node type: geth Network: main Platform: win32 (Architecture x64) … flag provided but not defined: -support-dao-fork I was at a loss. Googling actually didn’t turn up anything useful at all which was even more surprising. The way I eventually resolved this was to download the latest version (0.8.8) which loaded up correctly and re-sync. No funds were lost things are back to normal again!

When was Mist introduced?

Mist was introduced on July 9th 2016. It was labelled not as version 1.0 or 0.1 but as 0.8. This is because it continued using the version number of the Ethereum Wallet. https://github.com/ethereum/mist/releases/tag/0.8.0 links to the release and also explains the thinking behind the Mist/browser concept. You can think of Mist as the browser for decentralized apps. Like what Firefox or Google Chrome are for the Web 2.0, the Mist Browser will be for the Web 3.0. What is interesting is that in November 17 2015 in v0.3.6 there was a secret open source release of Mist (https://github.com/ethereum/mist/releases/tag/0.3.6) that essentially served as an early access programme.

Wellington October Blockchain Meetup

Another interesting evening at the Wellington Bitcoin/Blockchain meetup. I presented on “How transactions are secured on the blockchain”, got some audience participation and gave a live demo as well. We took a closer look at the genesis block from the bitcoin blockchain and looked at the components of a single block. We highlighted the point that to understand how a blockchain works, it’s valuable to understand what’s in a single block. We went through some hands on Proof of Work examples where I dusted off my origami skills and made some candidate blocks. We had a race to see who could roll a 3 or lower. The winner then got their version of the block secured on the blockchain. There were some really good discussions afterwards on China’s involvement, on bitcoin scaling, on how blocks were constructed and if someone could create their own block if it followed all the right specifications. Many of the audience members contributed their knowledge and point of view also. Here is a pdf to the presentation. securing-the-blockchain-key Thanks to Sebastian and Wyn from API Talent for their hospitality.

Ethereum update their crowdsale tutorial page

I was surprised at why the sample code was set as regular text. Seems likes the guys at Ethereum may have missed an opening bracket or something. It was good though to see Ethereum update their crowdsale tutorial page at https://www.ethereum.org/crowdsale. I’m sure others would have noticed this as well!

Let’s experience the blockchain using Ethereum

Everybody uses the Internet to exchange information but with the blockchain we can exchange and transact value and make contracts about how this is done. Ethereum is a public blockchain that provides a decentralized virtual machine that can execute peer-to-peer contracts using a cryptocurrency called ether. Time to experience Ethereum for yourself in a safe test environment. The first step is to download Mist. Mist is a “wallet/browser” used to store ether and interact with Ethereum contracts.  It is easy to use and you don’t have to be a developer or write any code. It will take about 5 minutes to set up the wallet but about 1 hour to sync to the network and about another hour to successfully mine some test ethers. Step 1: Download Mist Go to https://github.com/ethereum/mist/releases and find the latest version to download for your system. You will see a number of options for downloading. Choose the one which is right for your device. For example, if you are using the Windows platform and have a 64 bit machine you will choose Etherium-Wallet-win64-0-7-5.zip Step 2: Installation At this point you will be shown a screen that asks you whether you want to connect to the ‘real’, main […]

Ethereum – creator of smart contracts in a decentralized network

Ethereum is a platform that allows the creation of smart contracts. To understand how Ethereum works, it is important to appreciate the underlying concepts upon which it was built, that is Bitcoin and the blockchain. When the first bitcoin transaction took place on the 3rd of January 2008, (known as the genesis block), it introduced to the world the concept of ‘decentralized consensus’. This is where everyone on the bitcoin network agrees that something has changed ownership, forming a ’crypto-currency ledger’. The “bitcoin” blockchain is simply a collection of all transactions since bitcoins started, mathematically linked together to form a chain. The blockchain also encapsulates some key concepts: Public Key Cryptography (the ability to verify and authenticate a message from a sender using a set of public and private keys that are mathematically linked. Cryptographic Hash Functions (a function which takes an arbitrary length input or ‘message’ and returns a fixed-size alphanumeric string, which is called the hash value – sometimes called a message digest, a digital fingerprint, a digest or a checksum) Peer to Peer Networking (computing or networking through a distributed application architecture that partitions tasks or work loads between peers. Peers are equally privileged participants in the […]
