According to CryptoPotato, Polkadot has introduced the Join-Accumulate Machine (JAM) protocol, which combines features of Polkadot and Ethereum to enhance blockchain efficiency and scalability. The protocol's implementation is subject to community approval. Additionally, Polkadot is in discussions about a potential $8.8 million sponsorship deal with Inter Miami CF.
The JAM protocol provides a global singleton permissionless object environment, similar to the smart-contract environment pioneered by Ethereum, paired with secure sideband computation parallelized over a scalable node network, a proposition pioneered by Polkadot. The protocol will also support existing parachains, allowing developers to continue using Substrate for blockchain deployment. The protocol will only interact with DOT; no new token will be issued. The community must approve JAM via Polkadot’s on-chain, decentralized governance.
Several top Polkadot parachains have also seen significant developments. The Acala Network recently announced the Sinai Upgrade, designed to enhance the platform’s position as a liquidity layer in the Web3 space. The upgrade includes a liquidity track, infrastructure track, and aSEED track. Following Polkadot’s runtime upgrade, all parachains stopped producing blocks for approximately one hour. However, the Moonbeam Network, one of the leading parachains, resumed block production and returned to normal operations on April 21.
In other news, Nico Zini, Partnership Marketing and Media Rights for Inter Miami CF, revealed that the American football team might enter into an $8.8 million sponsorship deal with Polkadot. The club’s co-owner is English football icon David Beckham, and its biggest star is Argentine legend Lionel Messi. This is not Polkadot’s first attempt to enter the sports world. In 2022, it sought to become FC Barcelona’s official jersey sponsor, but the Catalan club chose Spotify over the blockchain protocol.
