Singapore and Thailand to Enable Cross Border Payments Using Only Mobile Numbers in 2021
The linking of Singapore’s PayNow and Thailand’s PromptPay national fast payments systems will go live in mid-2021. Anyone registered with PayNow or PromptPay will be able to instantly and securely send money between the two countries using just their mobile numbers 24/7 at “competitive” rates. It will start off with a small group of banks on both sides, and scale up participation to include more banks and non-bank providers over time. The Monetary Authority of Singapore is keen to partner other central banks in the region to expand the linkage.
BDoS: Blockchain Denial of Service
This paper introduces an incentive-based blockchain denial of service (BDoS) attack that targets proof-of-work (PoW) crypto-assets. Unlike classical DoS, BDoS targets the system’s mechanism design: It exploits the reward mechanism to discourage miner participation. Previous DoS attacks against PoW blockchains require an adversary’s mining power to match that of all other miners, requiring that the attacker obtain at least 51% of the network’s mining capacity. In contrast, BDoS can cause a blockchain to grind to a halt with significantly fewer resources, e.g., 21% as of March 2020 in Bitcoin. We find that Bitcoin’s vulnerability to BDoS increases rapidly as the mining industry matures and profitability drops.

Long-Term Bitcoin Holders Are Selling Off Their Coins
A metric that tracks how much dormant Bitcoin has been recently moved, indicates that long-term Bitcoin holders are realizing profit on their Bitcoin. The Bitcoin Coin Days Destroyed metric measures when dormant Bitcoin is sold. The older, and the greater amount of Bitcoin, the higher the metric goes. And recently, it has been shooting up. According to Glassnode’s The Week On-Chain newsletter, “while so many long-term holders remain in a state of significant profit, sideways or downwards price movement can be expected as they realize these profits.”
