SummaryPolkadot has seen increased activity over the last few months.The new roadmap gives us some exciting things to look forward to.I believe Polkadot could outperform going forward.OverviewPolkadot (DOT-USD), the blockchain focused on interoperability, has seen a steady increase in development activities, according to data obtained from Santiment. Polkadot's GitHub saw over 500 contributions each day in September; reaching a new all-time high of daily contributions in a month. In August, there were 14,930 contributions on Polkadot's GitHub. Polkadot brings together a network of heterogeneous blockchains called parachains.Parachains in Polkadot are individual Layer-1 blockchains that run in parallel, connected to the Polkadot relay chain. Some popular blockchain networks, including KILT Protocol, Acala, and Astar, run as parachains on Polkadot. KILT protocol recently became the first parachain to fully migrate from the Kusama network to Polkadot's relay chain. Projects building on Polkadot start their development on Kusama, Polkadot's "canary" network. Kusama can be likened to pre-production, experimental environment where teams can deploy and stress-test new technologies.To become a parachain on Polkadot, Layer-1 projects bid for a parachain slot, as Polkadot's parachain slots are currently limited - estimated to be around one hundred available slots. Parachain slots are assigned in an on-chain auction. Projects that win a ...
