When these validators discover a useable block, they hedge their money on that block being certified—if they are correct about block, they are rewarded; if incorrect, they lose the money that they hedged.

The major benefit of the Casper PoS is that it has designed the Ethereum blockchain to prioritize pragmatism over user-trust. Casper is specifically designed to deter instances of potentially harmful blocks for individual benefit. The more commonly noted method of scaling blockchain technology involved off-chain scaling.

This is the method that was embraced by earlier cryptocurrencies, such as Bitcoin. I think that Ethereum is employing off-chain strategies as a result of its partial success in the past. My definition of off-chain includes tactics to make the use of blockchain more efficient without altering the blockchain itself , as well as decrease the use of the blockchain while increasing overall transactions. What exactly is a Raiden state channel? Essentially, the Raiden Network is channel for transactions to occur without using the blockchain every time.

The purpose of the Raiden Network is to increase the speed of transactions while decreasing the cost. By avoiding the Ethereum blockchain and using its own channel to trade Ether, Raiden holds the potential to enable millions of micro-networks to facilitate off-chain transactions.

The main benefit of this—it dramatically decreases the burden and requirements of Ethereum to handle. Plasma, essentially, creates its own network of blocks, similar to a blockchain—only it is more of a sub-blockchain to the overall Ethereum network. The plasma system relies on incentivizing smart contracts to allow a massive amount of state updates per second. This process relies more on user-censorship for identifying misuse of the blockchain.

Through the plasma network, other users are responsible for flagging negatively intended usage of Ethereum. You want to play? A reference implementation is being built in python on top of Py-EVM , and a testnet in python is not too far away.

And in this next step, we want you to be involved. We want the Ethereum sharding testnet, and later sharding mainnet, to be a multi-client ecosystem right from the start, with the Ethereum Foundation not supporting any single privileged production implementation. The Ethereum Foundation-funded research team will continue to build an implementation in python and possibly other languages, but this is intended as a reference and proof of concept first and foremost.

Instead, the Ethereum Foundation will be making subsidies available to independent groups in the community that want to help build an implementation and participate in the sharding testnets and mainnet.

These payments are NOT intended to be sources of substantial profit to recipient organizations; they are rather intended to cover some of the costs involved, with the understanding that anyone who participates in the scheme will have access to a unique opportunity to participate in Ethereum 2. This will take the form of a specialized program, which will exist alongside more general grant program that the Foundation will release soon.

Participants will interact closely with the core research team, and will have a key role in shaping the final specification that gets developed over the course of implementing the spec and running the test networks. There has been a large number of independent proposals recently for how blockchains such as Ethereum can be scaled up through second-layer protocols.

We recognize and appreciate that developers and researchers are excited about researching and implementing technologies in this area, and that many teams want the freedom to conceive and build out their own design that incorporates their own ideas. We want to offer an opportunity for such teams to exercise their creativity and build out their scalable blockchain proposals, all while staying within the Ethereum family.

The subsidy may be available even if the project has an independent business model, or funding from potential other sources in the Ethereum community, though we will prioritize funding projects that otherwise lack ability to sustain themselves, and it absolutely must be the case that the work funded is open source from end to end and provides a common good to the Ethereum ecosystem. Both of these programs are in a very early stage, and grants will be initially decided at the discretion of Ethereum core leadership.

Details, including the terms, conditions and schedules under which payments will be made may change as the result of our initial experience with program participants, and we expect the program to solidify and expand over the course of the year. Note also that though the payments from these collaboration programs are much higher than those that we have made from our previous grant programs, these payments come with a much higher expectation of focus and quality.

The programs are also highly targeted at sharding clients and layer-2 scaling solutions; this is NOT a general-purpose grant program.
