The development of blockchain projects is complicated by several factors. One of them is that servers’ remoteness causes slow data synchronization and validation of transactions in the network due to the insufficient quality of the infrastructure. The creators of the #MetaHash system have foreseen this factor and set a goal to design geo-distributed network architecture with minimum synchronization time while maintaining maximum data bandwidth capacity with high-speed multi-blockchain based on #TraceChain protocol.

In our network, the distribution of roles and, accordingly, rewards, is based primarily on successful passing load tests, the number of delegated coins, the nodes’ physical features, such as memory, CPU performance, and network connection. In the future, the node trust will also be taken into account. However, these are not the only criteria which determine the increase or decrease of node reward: the geographical location has become an equally important factor.

The financial incentive system, based on the roles assigned to nodes, is aimed at adding nodes with the maximum throughput capacity, uniformly among all roles and “latency zones” (usually it depends on the geographic location). Therefore, a geolocation coefficient (Cgeo) was introduced, which is specifically taken into account while calculating the rewards (for more details, please read Yellow Paper #MetaHash). It encourages users to develop the infrastructure and launch nodes in regions with fewer nodes (often ones with expensive operations), charging the node with a special bonus for being in “difficult” geo and thereby leveling its low response rate. By the way, on this map, you can track the geographical distribution of active nodes.

As shown above, the node reward for delegation should be higher in the geo where there will be fewer servers or where other users have delegated a smaller amount of coins. Why? The node’s reward is distributed only to those who delegated coins to that node: less delegating — fewer competitors — higher reward. With an increase of the number of roles in the network, the fixed part of the reward share will decrease, while the share depending on the server’s number in the geo zone will only increase. Here you can learn more about the new system of rewards distribution and accrued geo-coefficients. With the activation of each new role, we will announce changes in the rewards distribution.

The fact that we managed to develop an optimal structure for synchronizing a geographically distributed network is proved by a high bandwidth (more than 18 megabytes per second) which allows processing more than 50,000 operations per second, including verification of the sender’s signature and balance check for a successful transaction. Therefore, forging in an “unpopular” geographic zone will increase your chances of receiving a higher reward.
