We recently released version 0.15.2 as a mandatory security update for the GameCredits network. This release includes a first-of-its-kind integration with the Komodo platform, allowing their blockchain to frequently “notarize” or write down certain block hashes into their chain as a backup system.
We’re incredibly excited about this Komodo integration, as it offers an extra layer of security that very few other POW coins currently have. In fact, GameCredits is the first coin to be interchain linked with Komodo.
How Komodo will help protect GAME from consensus attacks:
Let’s go into some technical detail to explain how this integration works and why it will have such huge benefits for GameCredits.
In the past few weeks, we’ve seen reports of consensus attacks on large crypto projects such as Verge (XVG) and Bitcoin Gold (BTG). We faced some consensus attacks as well. These attacks are known as double-spends. Here’s how they work:
1) An attacker sends a transaction.
2) The attacker mines blocks on a chain with his/her own or rented hashpower (usually by forking off), but refuses to broadcast these blocks on the network. These blocks do not contain his/her original transaction from step 1.
3) The attacker’s transaction is confirmed on a service (like an exchange), so he/she gets credited for the transaction.
4) The attacker broadcasts the blocks on the network, erasing the existence of his or her transaction. Now he or she has been credited coins on the service he/she sent to and he/she still has the coins.
Our new Komodo notarization feature greatly reduces the impact of such an attack. Komodo notaries are running GameCredits clients and monitoring the network 24/7/365. At a certain interval of blocks, these notaries get the hash of a block and write it into the Komodo chain. They also note down which Komodo block has the nota...
