The network hashrate is the combined computing power that all miners worldwide contribute to the Alephium network. It is mined with specialised Blake3 ASICs, such as the Goldshell AL series. A rising hashrate means more competition for the same emission - earnings per terahash decline; a falling hashrate works the other way round. Next to the price, the hashrate is therefore the most important network metric for miners; it is also a measure of chain security, since any attack attempt becomes more expensive as total hashrate rises.
With Proof of Less Work (PoLW), Alephium relies on a protocol that requires less energy per unit of security than classic proof of work when network activity is high. Instead of buying security exclusively through ever more computing power, PoLW ties energy expenditure to actual network utilisation. For miners, the basic mechanics stay the same: your share of the reward depends on the ratio of your own hashrate to the network hashrate.
Alephium does not run on a single linear blockchain but on several parallel chain groups connected via the BlockFlow architecture. This sharding increases the network's throughput, because several chain groups can process blocks at the same time. For the network hashrate, this means it is spread across the individual chain groups, while the total hashrate shown here reflects the sum across all groups.
Unlike many pure payment coins, Alephium supports smart contracts and is thus designed for more than simple value transfer. The network hashrate secures not only transactions but also the program logic executed on the chain - an additional reason why a stable, widely distributed hashrate matters for the network.
Cryptohall24's dataset goes back to Alephium's mainnet launch in November 2021. Since then, the record has grown by one data point per day from our own monitoring - the charts above show the full history with a freely selectable time range.
