Bitcoin swung on a drop in US inflation and a rate rise in Japan; Solana endured a major DDoS<\/span> attack; the Ethereum team outlined details of a new upgrade; and other events of the week.<\/p>\n

US inflation and Japan\u2019s rate<\/h2>\n

Over the past seven days bitcoin fully surrendered the momentum gained after the rate cut<\/a> by the Fed<\/span> on 10 December. The coin was choppy as other macro data arrived.\u00a0<\/p>\n

On Monday the leading cryptocurrency started with a drop, sliding<\/a> from $89,000 to $85,000.\u00a0<\/p>\n

Over the next few days the asset recovered, and on Wednesday tried to break resistance around $90,000. It failed and fell back to $85,000.<\/p>\n

On Thursday, 18 December, sentiment was lifted by the the release<\/a> of the US Consumer Price Index (CPI). The gauge decreased by 0.3% and, on an unadjusted annual basis, reached 2.7% (3% in October).<\/p>\n

The figures undershot forecasts: analysts had expected 3.1%.<\/p>\n

Lower inflation again pushed bitcoin towards $90,000, but not for long. That evening the asset slipped below $85,000.\u00a0<\/p>\n

On 19 December the digital gold returned to an uptrend on news from the Bank of Japan. The regulator announced<\/a> a rise in the benchmark rate to a 30-year high.<\/p>\n

The market\u2019s reaction surprised many participants. Most analysts had expected a proportional response by cryptoassets to the negative news from Japan, yet prices rose.\u00a0<\/p>\n

Even so, the coin ended the week in the red, down roughly 1.5%.<\/p>\n

Most top-10 coins by market capitalisation followed bitcoin. The exception was XRP, which added 2.7%.<\/p>\n

SOL (-4.9%) and DOGE (-4.4%) fell the most.<\/p>\n

Total crypto market capitalisation stands at $3.08 trillion. Bitcoin\u2019s dominance is 57.3%; Ethereum\u2019s is 11.7%.<\/p>\n

A DDoS attack on Solana<\/h2>\n

The Solana blockchain weathered<\/a> the fourth-largest DDoS attack in its history. Attackers tried to overload the network for roughly seven days, but developers managed to repel<\/a> the interference.<\/p>\n

Malicious traffic peaked at 6 Tbps<\/span>. In terms of sheer volume, the incident was on a par with attacks on the infrastructure of Google Cloud<\/a>, Cloudflare<\/a> and AWS. Despite the pressure, the blockchain continued processing transactions as normal.\u00a0<\/p>\n

Pipe Network noted that average transaction confirmation time on Solana stayed around ~450 ms, with the p90<\/span> metric below 700 ms.\u00a0<\/p>\n

Solana founder Anatoly Yakovenko called both the episode and the chain\u2019s response a \u201cbullish\u201d factor.\u00a0<\/p>\n

On 14 December the L1 network Sui<\/a> also came under a DDoS attack. In its case the incident caused delays in block production.\u00a0<\/p>\n

During the week the Solana Foundation also entered into a partnership<\/a> with Project Eleven to prepare the network for potential threats from quantum computers. Specialists assessed the blockchain\u2019s risks and created a testnet prototype using post-quantum digital signatures.\u00a0<\/p>\n

\n

\u201cOur responsibility is to ensure the blockchain\u2019s security not only today, but for decades ahead. The Solana ecosystem\u2019s culture of rapidly implementing innovation will continue with the release of a second client and a cutting-edge consensus mechanism this year,\u201d said Solana Foundation vice-president of technology Matt Sorg.\u00a0<\/p>\n<\/blockquote>\n
