I0coin's specifications were chosen to provide the optimal balance across a broad spectrum of users. It's well balanced whether you're making a purchase, mining, or investing. The wallet requires only 425 MB of memory (fully synced). Its quick 90 second transaction confirmations make it excellent for making purchases, without being so fast as to sacrifice security. I0coin can be mined essentially for free since it is merge mined with Bitcoin. The maximum number of coins is permanently capped at 21 million, so you never need to worry about inflation devaluing your coins. This makes I0coin a great long term investment. Many other top coins, on the other hand, have unlimited coin supplies.

For the latest addnode list for your i0coin.conf file go to addnodes (click on 'node list' on the network tab).
These are useful if you have syncing problems with your wallet if it's not connecting to other nodes.
I0coin has a large blockchain which may take days to download in its entirety using the wallet. At the links below you may download a recent blockchain to speed your wallet setup. Unzip it to your i0coin data folder. These blockchains may be used with wallet versions 0.11.9 or later. The pruned blockchain requires the line "prune=550" to be added to the i0coin.conf file. Adding this line keeps only the last 550 MB of the blockchain. The pruned blockchain is great for users with space restrictions, even those who are mining. The full blockchain is best for users who want to maximize their support of the i0coin network. Some nodes with full blockchains are essential for a healthy network, so please choose this option when possible.

July 9, 2016 - I0coin Version 0.12.0.1 Released
I0coin version 0.12.0.1 has been released. This corresponds closely to Bitcoin 0.12.0. It is a minor upgrade from I0coin version 0.12.0, with no functional changes, only text message changes. It updates any reference to 'Bitcoin' with 'I0coin'. For anyone who doesn't like those 'Bitcoin' output messages this upgrade is for you. Since I0coin, and essentially all the Bitcoin merge mined coins, use Bitcoin code as their underlying baseline (for mining compatibility reasons) we occasionally have straggler 'Bitcoin' references in our updates. This will clean those up. Enjoy!
April 29, 2016 - I0coin Version 0.12.0 Released
I0coin version 0.12.0 has been released. This corresponds closely to Bitcoin 0.12.0. It brings I0coin up to the latest feature set as well as ensuring continued optimal security for its users. As a reminder, all miners must upgrade to 0.11.9 or 0.12.0 due to incompatibilities with older versions.
November 15, 2015 - I0coin Version 0.11.9 Released
I0coin version 0.11.9 has been released. This corresponds closely to Bitcoin 0.11.1. All miners must upgrade due to incompatibilities with the older versions. This release fixed the openssl security issue that impacted most cryptocurrencies. It also reduced the size of the block chain to about half of the previous version, without any loss of transaction data. On top of that it introduced block chain pruning. Pruning allows users to set the size of the block chain on their local device to as low as 550 MB, by retaining only the latest blocks. This is especially important for anyone running i0coin on a smaller device like a tablet or phone. It also allows “thin clients” to be run on web hosts for vendors, exchanges, and information sites which do not need access to the whole block chain.
