Introduction Having previously written a blog about the overall architecture of PolkaBTC, in this blog we will understand specifically how PolkaBTC works. PolkaBTC has been renamed Interlay BTC Bridge, where the previously running Staked Relayer has been merged into the Valut module. Interlay uses the XCLAIM protocol framework, where BitCoin assets are locked in the Bitcoin chain, which then generates a 1:1 corresponding InterBTC token on the Interlay chain, and InterBTC Token can be used on parallel PolkaDOT ecological chain. For most investors who invest in digital currencies, Interlay chain is a pseudo demand, however, refer to the whole stock market as well as futures trading market, digital currency exchanges, they are nothing but centralized and users will transfer and exchange different kinds of assets, to the world of digital currencies, what we want is decentralized exchanges, exchanges rely on smart contracts to complete transactions, Bitcoin is Bitcoin is the leading digital currency, currently the way to get bitcoin we can only get it through exchange or mining, I have ETH, I have to transfer ETH to a centralized exchange and then exchange it for BTC, if it is a cross-chain decentralized exchange, then we can directly transfer assets to Tokens of other chains through cross-chain protocols, the advantage of this process compared to centralized exchanges The advantage of this process over centralized exchanges is that it is efficient and secure, think about what if the centralized exchange runs away! At a later stage my goal is to be able to use quantitative strategies to profit in the world of cryptocurrencies, which involves knowledge in the field of algorithmic strategies and high frequency trading quantitative investments. ...

Opening Reasons for choosing to support this project: believe in BTC believe in PolkaDot we need decentralized exchange Project description PolkaBTC Project is a parallel chain built on PolkaDot to bridge the BTC Chain, using the XCLAIM protocol to bridge BTC across the chain to the PolkaDot ecosystem, with a token named PolkaBTC, with BTC assets locked to the BTC chain and minted in the Polkadot system at a PolkaBTC is a token anchored to BTC in a 1:1 ratio in the Polkadot system. PolkaBTC is able to convert between parallel chains like all native tokens in the PolkaDOT ecosystem, and there is no risk of centralization in the PolkaBTC bridging project, like companies, communities, and individuals can all participate in running BTC parallel chains. ...

References [Polkadot Lightpaper] () Polkadot architecture Polkadot is called a next-generation blockchain protocol, which is a multi-chain system that allows the exchange of data between any other blockchain, in contrast to the common [PoW](https://en.wikipedia.org/wiki/Proof_ of_work) mining than the common PoW mining, I prefer something like Polkadot to generate blocks through NPoS, where we can directly run nodes on thousands of edge devices, which makes the whole chain with stronger security and decentralization of the whole chain. ...

Summary This article will not go into too much technical details about ETH, but will mainly deal with how to become a validator of ETH 2.0. At the end of this year, ETH will complete the stage 0 upgrade, migrating from PoW proof-of-work to PoS proof-of-stake. Before myself at the company’s hackathon com , I thought about how to use the excess arithmetic power to do something valuable. PoW is theoretically more wasteful of energy, and miners buy a lot of mining machines for computing, while after adopting the PoS mechanism, by becoming a validator, we can finish the Instead of buying a lot of mining machines to generate new blocks like PoW, to become a validator you need to lock a certain amount of cryptocurrency as proof of interest, if you run a verifying node to verify a block and check if all the transactions inside are valid, if it passes, you will receive a reward in return. ...

The last two days the company planned a hackathon competition, they simply signed up to participate, thinking that they are currently researching the topic of deep learning, on the Google search blockchain deep learning, and finally found this paper Energy-recycling Blockchain with Proof-of-Deep-Learning, and then developed a PoDL chain for storing deep models along the lines of the paper, which is presented below, followed by Mathematica and Python implementations. Program Code. ...
