While Bitcoin grabbed headlines with its resilience above $8,300, the Ethereum ecosystem was quietly building the infrastructure that would power the next wave of decentralized applications. The week ending October 13, 2019, brought several significant developments for Ethereum and the broader altcoin space, including the launch of NuCyphers public testnet, major updates to MyCrypto, and the expansion of Ethereum.org into 11 languages.
TL;DR
- NuCypher launched its public testnet, bringing privacy-preserving encryption to Ethereum
- Ethereum.org became available in 11 languages, signaling a global push for developer onboarding
- MyCrypto released a beta version with multi-account management and redesigned UX
- Ethereum traded at $182.08 with a $19.7 billion market cap, gaining 5.45% over the week
- Tezos (XTZ) gained 2.22%, Chainlink (LINK) posted 13.9% weekly gains despite a daily dip
NuCypher Brings Privacy to Ethereum
One of the most notable developments of the week was NuCyphers launch of a public testnet. NuCypher is a privacy layer for Ethereum that uses proxy re-encryption to allow developers to securely share and manage private data on public blockchains. The technology enables what the team calls “dynamic access control” — allowing data to be encrypted once and then shared with specific parties without revealing the underlying private keys.
The testnet launch represented a critical milestone for Ethereum privacy infrastructure. Until this point, most privacy solutions in the Ethereum ecosystem had focused on transaction-level privacy through mixins or zero-knowledge proofs. NuCypher approached the problem differently, providing a general-purpose encryption layer that any decentralized application could use. This opened the door for healthcare dApps, decentralized credential systems, and secure data marketplaces — all use cases that had been bottlenecked by the lack of a reliable privacy layer.
Ethereum.org Goes Global
In a move that underscored Ethereums international ambitions, the Ethereum Foundation announced that Ethereum.org was now available in 11 languages. The multilingual expansion was designed to lower the barrier to entry for developers and users around the world, particularly in regions where English proficiency was limited but crypto adoption was growing rapidly.
The timing was significant. Ethereum was in the midst of planning its transition to Ethereum 2.0, a proof-of-stake system that would require broad community participation for staking and validation. Making educational resources accessible in languages including Chinese, Korean, Spanish, and Russian was a strategic move to ensure that the validator community would be globally distributed from day one.
MyCrypto Overhaul Improves User Experience
MyCrypto, one of Ethereums longest-standing wallet interfaces, released a new beta version featuring multi-account management and a completely redesigned user experience. The update addressed one of the most persistent criticisms of Ethereum wallet software: the difficulty of managing multiple accounts and interacting with smart contracts without technical expertise.
The redesigned interface introduced a cleaner layout, improved transaction flow, and better integration with hardware wallets. For a ecosystem that was trying to attract mainstream users, these UX improvements were not merely cosmetic — they were essential infrastructure. The gap between Ethereums technical capabilities and its usability had long been cited as a barrier to adoption, and MyCryptos overhaul was a step toward closing it.
Price Action and Market Context
Ethereum was trading at $182.08 on October 13, with a market capitalization of approximately $19.7 billion. The second-largest cryptocurrency had gained 5.45% over the past week, outperforming Bitcoins 4.37% weekly gain. ETHs 24-hour trading volume reached $6.73 billion, reflecting strong market interest.
Among other altcoins, Chainlink (LINK) had posted an impressive 13.9% weekly gain despite a 4.19% dip on October 13 itself, trading at $2.50. Tezos (XTZ) continued its quiet resurgence with a 2.22% daily gain to $0.90. IOTA gained 3.24% to $0.279, and TRON (TRX) advanced 2.46% to $0.016.
The broader altcoin market was showing signs of life after months of sideways trading following the Bakkt launch disappointment in late September. Total market capitalization for all cryptocurrencies hovered around $220 billion, with Bitcoin dominance at approximately 68%.
Research and Academic Progress
The week also saw the publication of a notable research paper by Hasu, Prestwich, and Curtis that proposed a new model for understanding Bitcoins security under declining block rewards. While primarily a Bitcoin-focused paper, the research had implications for Ethereum, which was preparing its own transition to a proof-of-stake model where block rewards would be restructured entirely. The paper sparked discussions across both communities about the long-term sustainability of blockchain security models.
Why This Matters
The developments of October 13, 2019, illustrated a crucial truth about the cryptocurrency space: while price action dominates headlines, the real progress happens in the infrastructure layer. NuCyphers testnet launch would eventually become foundational for privacy-preserving DeFi applications. The Ethereum.org multilingual expansion foreshadowed the global validator network that Ethereum 2.0 would require. MyCryptos UX improvements were part of a broader trend of making Ethereum accessible to non-technical users. At $182, Ethereum was a long way from its all-time high, but the building blocks for its future ecosystem were being laid one week at a time. For investors paying attention to fundamentals rather than price charts, the signals were clear: Ethereum was building for the long term.

proxy re-encryption is genuinely clever tech. NuCypher was solving real problems while most 2019 projects were just whitepapers
proxy re-encryption was legitimately novel. NuCypher was one of the few 2019 projects with actual cryptographers on the team
Ethereum.org in 11 languages is an underrated milestone. Developer onboarding at scale matters more than price action.
ETH at $182 with a $19.7B market cap and people were bearish. the 11-language push for ethereum.org was the kind of boring infrastructure work that compounds over years
Bojan M ETH at $182 with $19.7B cap and people were bearish. the 11 language push was the kind of infrastructure work that built the foundation for everything that came after
Teodora M. the 11 language push was 2019 and most L2 docs in 2026 still only have english and chinese. ethereum.org was genuinely ahead
11 languages was ambitious for 2019. most crypto docs were english-only back then. the developer base outside the US was growing fast and needed docs
Dmitri V. 11 languages in 2019 was genuinely ahead of its time. most L2 docs in 2026 still only have english and maybe chinese
