Il collasso dell’AMOC diventa un rischio reale Quando un governo considera una corrente oceanica un problema di sicurezza nazionale, significa che qualcosa è cambiato davvero. L’Islanda ha ufficialmente classificato il possibile collasso dell’AMOC — la grande circolazione che porta calore dall’Atlantico ai mari del Nord — come minaccia esistenziale. Una decisione rara. E un segnale forte per l’Europa. Perché l’AMOC è così importante L’AMOC funziona come un gigantesco nastro trasportatore: acqua calda dai tropici sale verso nord, si raffredda, affonda e torna indietro in profondità. È questo flusso a rendere gli inverni europei sorprendentemente miti per la latitudine. Il problema è la velocità del cambiamento. L’acqua dolce proveniente dallo scioglimento della Groenlandia sta “diluendo” l’Atlantico del Nord, disturbando il meccanismo che permette all’acqua salata di affondare. Se l’affondamento rallenta, l’intero circuito si indebolisce. Se si ferma, collassa. Gli scienzia...

Moonbeam allows developers to run standard solutions with little or no code changes
Moonbeam allows developers to run standard solutions with little or no code changes and also provides a very convenient environment for launching new projects.
Function
Moonbeam has developed Unified Accounts, whereby users only need one private key to interact with both the EVM and the Polkadot Substrate (*other parachains that work with the EVM require two private keys, one for the Substrate and one for the EVM).
XC-20 Assets is a new token class that offers native parachain interoperability, whereby users and developers can interact using a familiar ERC-20 interface.
The Cross-Consensus Message (XCM) format defines how messages can be sent between interoperable blockchains. This format opens the door to transfer messages and assets (Substrate assets) between Moonbeam/Moonriver and the relay chain or other parachains in the Polkadot/Kusama ecosystems.
XC-20s are a unique asset class on Moonbeam. It combines the power of Substrate assets (native interoperability) but allows users and developers to interact with them through a familiar ERC-20 interface via a precompile contract (Ethereum API). Moreover, developers can integrate XC-20s with regular Ethereum development frameworks or dApps. Link [https://docs.moonbeam.network/builders/xcm/xc20/overview/]
Moonbeam Token #GLMR is a utility and governance token that allows holders to participate in management and is used to pay transaction fees (80% is burned and 20% goes to the on-chain treasury), as well as for node operation and smart contract execution.
As of April 2022, TVL is 342 million, or +130% per month, making Moonbeam a rapidly growing ecosystem.
