Reference TIDB architecture Why use TIDB the architecture used by the machine is ARM64. 2. trying to use a distributed database architecture. solve the high availability problem, when a Raspberry Pi database node is down, it will not affect the data writing. compared vitess and TIDB, TIDB is more compatible with ARM64, easy to start experimenting. prepare for the financial trading system later. Architecture Components and functions TIDB Server TIDB Server is a stateless application, it does not store data itself, load balancing can be placed in front, external application requests to nodes in TIDB Cluster, TIDB server will analyze and calculate the SQL requested by the application and forward the request to the underlying data store TiKV. ...

Competition Predicting high volatility digital currency market prices is difficult, G-Research has launched a contest project on kaggle.com about predicting digital cryptocurrency returns using machine learning, I am going to join the contest, later references and model building about the contest will be updated in that blog board.

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. ...

2021 Words to myself Risk-sharing think rationally Love random volatility Do unto others as you would have them do unto you 2021 A New Beginning I recently spent three months on my own reading the four-part series of uncertainty books by Nassim Nicholas Taleb. The overall summary of the feelings after reading is that, just right to make myself from deep inside out to find how to enhance their own anti-vulnerability through the judgment of randomness, correct my previous misunderstanding of the concept of investment, because many colleagues around me want financial freedom, then the question is how you want to approach this freedom, through the short-term constant speculation, speculation in digital currency If you look at the asymmetric risk, you will definitely end up with a 100% loss in it. ...
