Casper upgrade released

The first draft of the Casper proof-of-stake protocol upgrade from Ethereum developer Vlad Zamfir has been presented

Published on Tuesday, the code – following its presentation at the Devcon3 event earlier this month – intends to radically revise how blocks are created and distributed on the ethereum network. It is one of two concurrent applications to develop code for Casper, with the other arm being led by network creator Vitalik Buterin.

Zamfir's take on Casper comes several days after the publication of  a white paper, titled "Casper the Friendly Ghost".

The paper focuses on "correct-by-construction consensus protocols", seeking to facilitate how blockchains achieve consensus in a "partially synchronous network". This is an attempt to reduce the total complexity of the blockchain.

At the time when Zamfir's code release may represent on a small part of a bigger effort, its publication demonstrates a new phase of development that will lead ethereum a step closer to transforming the infrastructure that underlies the network.

Currently, miners discover and add new blocks through the proof-of-work process, which is energy-intensive process, driving miners to buy expensive power-hungry graphics cards.

Casper aims to get out of this model. Nodes could mine by essentially having funds deposited– the "stake" in proof-of-stake – and held over time, generating rewards as the node discovers each new block.

Sparkpool to Freeze $300k Reward

As reported, pool suggests that such a high commission could have been paid by someone in error and is considering the possibility of a refund

The Sparkpool mining pool decided to freeze the remuneration in the amount of 2,103,1485 for the extraction of block # 7,238,290. The management of the organization suggests that such a high commission could have been paid by someone in error and is considering the possibility of a refund, CoinDesk reports.

The head of the Sparkpool Xin Xu argues that users of the pool understand and agree with the decision, given the size of the amount involved.

Unfortunately, and fortunately, blockchain is so far not completely run by machines; human are still involved. So we have an opportunity to correct the problem. Integrity is our pool’s priority.

While some users suggested that a large commission was paid by mistake, others admitted that this could be a goodwill gesture from an anonymous donor to the community of the miner or even an attempt to launder money through the blockchain cryptocurrency.
