ZeppelinOS, a platform for smart contract applications in Ethereum

ZeppelinOS, a platform for smart contract applications in Ethereum

Today we’re excited to announce the first mainnet release of ZeppelinOS, a platform for developing, managing, and operating smart contract applications in Ethereum. You can start using it right now at zeppelinos.org. Until now, it was difficult and costly to fix problems in smart contracts.

Hundreds of millions of dollars were put at risk because of easy-to-fix vulnerabilities, but fixing them was too costly or even impossible. With ZeppelinOS, that will no longer be a problem. Developers can now build smart contracts that can be easily upgraded over time.

After CryptoKitties, the ‘Cryptocollectibles’ Business Is Booming

After CryptoKitties, the ‘Cryptocollectibles’ Business Is Booming

Development for CryptoPets started just four days after CryptoKitties’ launch on November 28, and is basically a cross between Pokémon and CrytoKitties. Owners’ pets can battle each other, and those who put in time and effort to “train” their pets will increase their value in the “adoption center,” Mitchell Opatowsky, project manager at CryptoPets, explained to Motherboard in an email.

The phenomenon of smart contract honeypots

The phenomenon of smart contract honeypots

Hardly a week passes without large scale hacks in the crypto world. It’s not just centralised exchanges that are targets of attackers. Successful hacks such as the DAO, Parity1 and Parity2 have shown that vulnerabilities in smart contracts can lead to losing digital assets worth millions of dollars.

Attackers are driven by making profits and with the incredible value appreciation in 2017 in the crypto world, individuals and organisations who hold or manage digital assets are often vulnerable to attacks. Especially smart contracts have become a prime target for attackers for the following reasons:
