TL;DR: On 24 May 2021, Polkadot nodes failed with an out of memory (OOM) error on block 5,202,216. This block contained an on-chain solution to the validator election, which is normally computed off-chain and only takes place on-chain if no off-chain solution is submitted. Due to the large number of nominators, the election overflowed the memory allocated in the Wasm environment.
While an update was being prepared to fix the issue, validators were asked to temporarily downgrade their node software to a previous version that includes a native (non-Wasm) version of the runtime. The native version is…
Polkadot Buildathon: India is an India-focused hackathon that aims to enable coders and entrepreneurs to create the technology needed for the next phase of the internet, with a prize pool of US$14,000.
Presented by Web3 Foundation Switzerland in association with Lumos Labs, it offers workshops and networking opportunities with leading international blockchain developers, running from March 30th to May 30th, 2021.
The Polkadot Network was launched in May 2020 by Web3 Foundation, a Swiss organization dedicated to supporting the research and development of Web 3.0. Co-founded by Dr. Gavin Wood, co-founder and former CTO of Ethereum, Polkadot is a next-generation…
The Berkeley Blockchain Xcelerator has announced its selection of the 2021 cohort of startups. Over 200 projects applied to take part, and several of the 21 selected teams have projects related to the Polkadot and Substrate ecosystems.
Berkeley’s Blockchain Xcelerator is a joint venture by the Sutardja Center for Entrepreneurship & Technology, the Berkeley Haas School of Business and the Blockchain at Berkeley student group. The program is designed to propel top blockchain entrepreneurs and scholars into the ecosystem; teams receive support from Berkeley mentors, researchers, faculty and venture capital firms and students.
The 21 projects selected cover a diverse…
Web 3.0, the next generation of the internet, has been envisioned as a fully functional and user-friendly web where our identity and data are our own — safely secured from any central authority thanks to decentralized blockchain technology. In line with this vision, Polkadot was created with the belief that no single blockchain can do everything; that rather, the future is multichain.
However, as the number (and often the size) of blockchain networks continues to grow, they remain largely cut off from one-another, like islands with their own communities and economies that can’t exchange information or value with the outside…
Support for Polkadot accounts has come to Ledger Live, including the ability to nominate and receive staking rewards.
Previously, Ledger Nano S and Nano X devices were supported when used in conjunction with Polkadot-JS Apps. Now, users have the option of managing their accounts and interacting with the network, including staking DOT, from within the Ledger Live application using their Leger hardware device to sign transactions.
In addition to basic account management and transaction functions, Ledger Live offers a convenient new way for DOT holders to nominate Polkadot validators and earn staking rewards. The application allows users to interact directly…
Kusama and Polkadot are independent, standalone networks built on very similar codebases, but Kusama has faster governance parameters and lower barriers to entry. While Kusama is wild and fast, Polkadot is more conservative, prioritizing stability and dependability, with slower, more methodical governance and upgrade processes. Kusama is great for bold experimentation and early-stage deployment. Polkadot is designed for stable execution of risk-averse, high-value applications.
As the launch of Polkadot draws near, many are asking how the network will compare to Kusama and how both will be used in different ways going forward. Below we’ll explore a few of the key…
To close out the year, we asked colleagues colleagues working on the launch of Polkadot to reflect on their work in 2019 and discuss what part of their work they’re most looking forward to in 2020. We’re excited to share their answers (some serious and some light-hearted!) with you below.
Responses come from almost every team at Web3 Foundation — from the Research and Communications to Infrastructure and Community & Growth — and from three continents. We also asked a few colleagues at our main development partner Parity Technologies to join in.
Enjoy! And see you in 2020.
The KILT Protocol team launched their first test net, “Mash-Net,” built on Parity Substrate. The open-source blockchain protocol enables trust markets through verifiable certificates and the integration of data sovereignty. KILT intends to secure a parachain slot after Polkadot main net launch and aims to provide the Polkadot ecosystem with an interoperable trust infrastructure to create numerous opportunities for both projects.
KILT Protocol has the potential to be an essential building block of Web 3.0: It allows users (persons, organizations, objects, artificial intelligence) to claim arbitrary attributes about themselves in a standardized way and receive attestation from trusted entities.
Web3 Foundation engaged Chain Security for an audit of the Polkadot Claims smart contract. The audit found 0 Critical, 0 High, 2 Medium and 9 Low level issues, all of which have been resolved in the latest commits to the code.
The Polkadot Claims contract is an Ethereum smart contract allows holders of the DOT allocation indicator token to claim their balances of DOTs to a Polkadot public key ahead of Polkadot genesis.
In order to launch Polkadot in a transparent and decentralized way, an Ethereum smart contract was required to hold data necessary to the genesis of Polkadot including…
Kusama is an experimental community research and development network.
Warning: this is an experimental network.
In Kusama’s mind, “R&D” stands for Risk and Danger. Introducing Polkadot’s wild cousin, its canary in the coal mine: the Kusama network.
Kusama is an early, unaudited and unrefined release of Polkadot. Kusama will serve as a proving ground, allowing teams and developers to build and deploy a parachain or try out Polkadot’s governance, staking, nomination and validation functionality in a real environment.
Kusama is a canary-net: It is an early, highly experimental version of Polkadot presenting real economic conditions. It is not…
