Delay of the Ice Age and its Implications

Posted: 14 Dec 2019 10:13 AM PST

Some among us seem to be indifferent to the economic realities that Ethereum faces. With some of the highest supply inflation of the top 10, issuance should be reduced if the ice age is to be delayed another 1.7 years.

Some say that they don't care about price. Okay, but do they care about having a vibrant Ethereum community? Do they care that new developers are being attracted to the space? Do they care that current projects are able to continue bootstrapping their funding? Do they care about overall community sentiment?

If so, then there should be a corresponding reduction in the issuance rate whenever the ice age is delayed. It is a fair quid-pro-quo between the miners and the rest of the ecosystem. The precedent has already been set with past ice age extensions. Why diverge from the norm in this instance, especially when the delay is CONSIDERABLY longer than those implemented before?

Has anyone built a functioning messenger dapp that uses Whisper?

Is there a list of the various ZK rollup techniques and their differences, pros/cons, etc? At the ELI5 level would be great.

Ethereum Devs: How to get all Ethereum transactions for an address

Posted: 14 Dec 2019 05:33 AM PST

Known Ethereum nodes lack functionality to get transaction list for ETH address (account).

If you are building application which offers user to see his transaction history, or making an explorer like Etherscan, the feature to list transactions by address is necessary.

To solve the issue, there is free and open source third-party solution — Ethereum transaction Indexer: https://github.com/Adamant-im/ETH-transactions-storage

The Indexer allows to explore transactions by Ethereum address and obtain a history of any user|wallet in just a move, like Etherscan does. Indexer is written in Python. It works as a service in background:

connects to Ethereum node (works well with geth or parity, others are not tested)
stores all transactions in Postgres database (including smart contract transactions)
provides data for API to get transactions by address

Indexer connects to Ethereum node and fetches transactions using JSON RPC, creating transactions Index in Postgres database. First Indexer will store transactions starting from block you indicate. After that, it will check for new blocks every 20 seconds and update the index. You may change the interval.

API for Ethereum transaction Indexer is published by Postgrest tool. If you need to provide public API, use any webserver like nginx and setup proxy to Postgrest port in config.

After index is created, you can use requests like

curl -k -X GET "http://localhost:3000/?and=(contract_to.eq.,or(txfrom.eq.0x6b924750e56a674a2ad01fbf09c7c9012f16f094,txto.eq.0x6b924750e56a674a2ad01fbf09c7c9012f16f094))&order=time.desc&limit=25"

https://yourserver.com/ethtxs?and=(contract_to.eq.,or(txfrom.eq.0x6b924750e56a674a2ad01fbf09c7c9012f16f094,txto.eq.0x6b924750e56a674a2ad01fbf09c7c9012f16f094))&order=time.desc&limit=25

The request will show 25 last transactions for Ethereum address 0x6b924750e56a674a2ad01fbf09c7c9012f16f094, ordered by timestamp.
