On October 15, blockchain pioneers Parity Technologies held sub0, a free online conference dedicated to its Substrate software development framework. The event, which ran from noon till 7pm CEST, featured executives and developers from Parity as well as ecosystem partners such as Snowfork’s Aidan Musnitzky and Limechain’s Daniel Ivanov. Parity founder Gavin Wood made the keynote speech.
Exposing the anatomy of substrate
Hosted on Crowdcast, sub0 was conceived to further the discussion and nurture deeper connections with the Substrate community. Written in Rust, Substrate represents a simple-to-use blockchain development framework, a tooling kit developers can use to create their own blockchain and Web 3.0 applications. Parity, which previously developed blockchain tech for the UN World Food Programme, engineered Substrate as well as next-gen sharded blockchain Polkadot, a protocol frequently touted as a challenger to Ethereum.
The sub0 event helped attendees develop technical skills, get to grips with tools for building superior blockchain infrastructure and applications, and learn more about parachains. Talks and demos catered to both experienced Substrate users and developers more familiar with other blockchains. In a keynote speech to kick off proceedings, Gavin Wood, who co-founded Ethereum before founding Parity, recounted the progress made with Substrate in the last two years and summarized the state of the framework. Wood also outlined his vision for the role he expects Substrate to play in the future of blockchain.
Following Wood’s keynote, talks included “What the Heck is Substrate?” by Parity CTO Fredrick Harrysson, “Anatomy of a Substrate Node” by developer advocate Dan Forbes, and “Run, Learn, Fix and Repeat: Launching the First Parachain Test Network” by core developer Bastian Köcher. Parity CTO Björn Wagner also dived into ecosystem trends and players and offered predictions as to where Substrate is heading.
Later, ecosystem partners such as Commonwealth Labs founder Drew Stone and BOTLabs CEO Ingo Rübe had their own 20-minute speaking slots. Attendees also got to learn more about Polkadot’s vision of uniting a network of purpose-built, interoperable blockchains in “Bridging Polkadot and Ethereum: Interoperability Today” which Snowfork Founder Aidan Musnitzky hosted.
Workshop sessions let devs get their hands dirty
After the talks concluded, community-led workshop sessions gave attendees an opportunity to get their hands dirty, with options for beginners, intermediate and advanced users. While the Beginner course was about building your own blockchain, one advanced workshop concerned the Frontier project, a compatibility layer that enables running unmodified Ethereum smart contracts on a Substrate-based blockchain.
The virtual conference follows last month’s launch of Substrate 2.0, with upgrades including off-chain workers and over 70 composable modules (known as pallets). The off-chain worker subsystem enables the execution of longer running and non-deterministic tasks. Live blockchains already running Substrate 2.0, meanwhile, include Polkadot and its canary network Kusama.
