The progress of deep learning (DL), especially the recent development of automatic design of networks, has brought unprecedented performance gains at heavy computational cost. On the other hand, blockchain systems routinely perform a huge amount of computation that does not achieve practical purposes ...
作者就提出了他们的深度学习证明(Proof-of-Deep-Learning, PoDL),让矿工把资源放到深度学习上去,而不是无用的计算。这个是让矿工通过进行深度学习训练,然后提交训练好了的模型作为证明。作者的工作主要有三点: 提出了第一个共识机制PoDL,通过深度学习而不是哈希计算来维护区块链 PoDL可以应用到任何基于PoW机制的加密...
The work of deep learning training is useful, and the model verification process is much shorter than its training process. Therefore, in this paper, we propose DLchain, a PoUW-based blockchain using deep learning training as the hard puzzle. Theoretical analysis shows that DLchain can achieve...
Answering some of your common questions. NFT or Non-fungible tokensis a unique digital identifier, stored on blockchain. It can be anything, a piece of digital art, some document, some video, etc. in our case it is like a badge (certificate), that acts as a proof that you have comple...
Proof-of-Learning with Incentive Security Most concurrent blockchain systems rely heavily on the Proof-of-Work (PoW) or Proof-of-Stake (PoS) mechanisms for decentralized consensus and security assurance. However, the substantial energy expenditure stemming from computationally intensive yet meaningless ...

Newbie blockchain users frequently ask that question: what is the “proof of work” in blockchain and why is it so cool? Let’s explain that shortly. Proof-of-Work, or PoW, is the consensus reaching algorithm in blockchain. They use it to confirm transactions and create new blocks. Actu...

Learn the difference between proof of work and proof of stake to validate and secure transactions on the blockchain network.
Proof of work Underproof of work, the updater (also called a "miner") is chosen via competition. Here's how it works. For each group of transactions, the blockchain assigns a complex puzzle that can only be solved with brute computing power. One way to think of this puzzle is like a...
