Cloudflare talked about the start of beta testing of Cloudflare Workers embedded scripts in web applications using Cloudflare Apps tools. The created solutions can be placed in the Cloudflare Marketplace store, where they will be moderated and a security check.

Application developers used Cloudflare Apps to integrate JavaScript, HTML, CSS, and modifications of Cloudflare settings such as DNS to websites. With the start of beta testing, they got the opportunity to experiment with personalization, A / B testing, security, content checking and localization.

To add code to the application, simply place the link to the script in the install.json file:

{
	"resources": [...],
	"hooks": [...],
	"workers": [{
		"src": "./worker.js"
	}]
}

The introduction of variables is also available with a link in the Workers script. They may contain the tokens necessary for installing the application.

// inside src/worker.js
addEventListener('fetch', event => {
  event.respondWith(workerFn(event.request))
  let someOptionFromInstall = INSTALL_OPTIONS.UserAgents // UserAgents was selected by siteowner in previewer
})

Cloudflare unveiled a stable version of Workers for cloud administration of web applications in JavaScript in mid-March 2018. The service allows you to deploy JS-scripts on the company's cloud network within 30 seconds. At the end of September 2018, Cloudflare launched the “key-value” repository of Workers KV. Cloudflare experts claim that Workers provides low latency data reading and allows you to create applications that are comparable in performance to content delivery networks (CDNs).

Specialists from the blockchain-startup Parity Technologies have discovered a vulnerability in the JSONRPC protocol that threatens the security of the entire Ethereum ecosystem. In particular, MyEtherWallet, MyCrypto and Infura services are under threat of hacking.

At the moment, the problem has already been fixed, the attackers did not have time to use it.

The developers of Parity Technologies recommended that users update the nodes to the new software version in order to reduce the risk of losing access to decentralized applications.

Recall that in January, due to the critical vulnerability in improving the EIP-1283, which allows hackers to steal user funds, the hardfork network was postponed indefinitely
Ethereum Constantinople.
