Decred uses a PoW+PoS hybrid consensus mechanism and divides block rewards to make power more decentralized. Miners receive 60% block rewards for submitted workloads, vote holders receive 30% block rewards, and 10% block rewards are injected into the community fund, allowing Decred to maintain development without external funds.

BitPay Chief Commercial Officer Sonny Singh (Sonny Singh) remains optimistic. He pointed out in an e-mail to Bloomberg that there has been a significant increase in crypto companies paying suppliers with bitcoin. This includes law firms, hosting companies, accounting firms, landlords and software vendors.

Based on the early framework, the goal can be achieved by simply expanding the capacity. On the basis of the above points, CSW believes that returning to version 0.1 only needs to continuously expand the capacity to establish a steadily expanding currency system and realize the world currency dream as soon as possible. Wu Jihan and others believe that there are still many challenges facing BCH, not only to expand the capacity, but also to get rid of various constraints, learn the advantages of altcoins, and improve user experience. More people will continue to use it to realize the world currency dream.

But performance/cost is not the only limitation of smart contracts on DApps. EOS has been able to achieve processing power of thousands of tps through the representative system, which is two orders of magnitude higher than the performance of Ethereum 1.0, and the transaction execution cost is borne by the developer, which makes DApps take off the slow and expensive hat. But the EOS mainnet has been online for a year, and there is still no real decentralized application. This makes people wonder, even if Ethereum is upgraded to 0 (it will take about 2 years), will the spring of DApps really come? After repeated thinking, I believe that in addition to performance/cost constraints, DApps also face the second important limitation of smart contract platforms: the absence of decentralized governance. In order to achieve and ensure verifiability, smart contracts exclude application upgrades, making it difficult for applications to repair defects and continue to optimize. Polkadot/Substrate has given Web3 application chain governance capabilities. By removing the two major development bottlenecks of performance and governance, Polkadot/Substrate is expected to trigger the third wave of Web3 applications. For in-depth discussions in this regard, please refer to my book "Unleashing DApp Innovation Potentials across Chains"

Except for the most basic tranRansom email bitcoin 2020saction structure, hashing algorithm, proof of work, longest chain rule, and incentives, the Bitcoin white paper does not define any specific technical details. Everything is left for us to develop and improve to adapt to the changing world in the future. Looking forward to the ultimate realization-Satoshi Nakamoto's vision of becoming a peer-to-peer electronic cash system.

Dust attack means that the attacker conducts a large number of low-value and low-fee spam transactions, occupying the block space, causing normal valuable transactions to be unable to be processed, resulting in block clogging; at the same time, in order to seize the opportunity for transactions to be packaged , The market will naturally raise transaction fees, so that applications based on the blockchain will be affected by excessive transactions.
