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.

The staged launch of Polkadot is about to reach another chapter. As we approach the launch of parachain functionality and the auctions and crowd-loans behind them, let’s look at what’s coming.

Despite being a tough year for pretty much everyone (with the possible exception of Amazon and takeaways), the Polkadot network and community is coming out of 2020 with the wind very much behind its sails.

The new Bounty Extension on Polkadot and Kusama allows curators to autonomously allocate Treasury funds to projects that bring value to the ecosystem.

DOT and KSM are now integrated on Gitcoin. To celebrate, we created Hello World! by Polkadot to bring you on a journey of Polkadot development discovery.

Parachains are specialized shards of Polkadot that give projects and their communities agency over their respective goals.

To make sure the teams building on Polkadot have all the support they need, it is paramount that they understand the funding alternatives available. One good funding option is the Polkadot Treasury, which is already supporting a wide range of projects.

Swisscom Blockchain AG has received a Wave 5 grant from Web3 Foundation to develop a Kubernetes Operator for sentry nodes and validators for both Kusama and Polkadot.

Token transferability will be enabled today, exactly at block number 1,205,128. This will occur at approximately 16:40 UTC, though it is impossible to exactly calculate this time. This will not change the denomination of DOT (old) which still represents 10**12 Planck.

On August 21st at approximately 13:15 UTC (block number 1,248,328), the DOT token will undergo a redenomination from its original sale. ‘New DOT’ will be 100x smaller than ‘DOT (old)’.
