29 MB azi.
Nu-mi place ce face F2Pool si am toata stima pt AntPool.
F2Pool pune cateva zeci de tranzactii, uneori cateva sute si blocuri sub 100 KB daca au trecut doar cateva minute de la blocul precedent, iar AntPool si mare parte din restul blocuri de aproximativ 950, 970 KB.

Am configurat nodul meu sa nu propage nici o tranzactie cu fee sub 0.0007 BTC/KB Angry

Imi spui pasii, te rog? Roll Eyes

Pui "minrelaytxfee=0.0007" pe undeva prin configuratie (fisierul bitcoin.conf).

A inceput sa scada dimensiunea tranzactiilor neconfirmate. Erau 67 MB acum 3 ore, acum sunt 62 MB.
Aproape toate blocurile au dimensiunea intre 900 KB si 1 MB.

Later edit: sa-i ia dracu de cretini cu tranzactiile lor de 0.0001 BTC. Nici n-a trecut un minut ca a mai aparut 1 MB de date.

Initial am crezut ca nu vad bine: Transaction Fees 5.27186516 BTC

Hell is coming.
Peste 20000 tranzactii, peste 56 MB size, doar 1 BTC fee pt toate 20000, tranzactii de 0.0001BTC.
https://blockchain.info/address/1aamWKicYga3AN8UgywedHzEG12KbUUJJ

Stai linistit ca nu e mare problema. Doar poti sa patesti sa iti intarzie mult tranzactia daca pui fee prea mic.

Eu ma uit pe blocktrail si apare "133,993 (140,757.09 Kb)" acum.

Eu eram pe blockchain: https://blockchain.info/unconfirmed-transactions
Acum blocktrail e in urma cu doua blocuri fata de blockchain Sad

A new round of massive transaction spam is underway again (won't affect this pool significantly as I've already put in place lots of customisations for this purpose).

Acum 6000 si 11 MB ca dimensiune. Trebuie peste 11 blocuri sa le ia pe toate. Unele sunt fara fee cred.
Si ieri erau vreo 3000 fara fee.

Cred ca au inceput Sad

Aparent se folosesc de lacomia oamenilor si dau fise gratis imprastiate grav, astfel incat oamenii trebuie sa faca multe tranzactii ca sa puna mana pe ele. Sa vedem cum decurge

Da, ar trebui să fie să zicem vreo 50k tranzacții neconfirmate pentru perioadă de măcar câteva ore ca să zicem că chiar o fi vreun atac din aceasta în desfășurare.

Cam asa ceva. Ei zic ca vor sa faca tranzactii cat sunt procesate intr-o luna Shocked

. Acum limita e 1MB la bloc. Daca le iese schema cred ca se va trece la BIP 100 intr-o saptamana si se rezolva problema.
Altfel nu stiu ce sa zic, vor fi milioane de tranzactii neprocesate.

3673 Unconfirmed Transactions

ce zici tu acolo?

M-am uitat ieri pe blockchain, trecusera 53 minute de la ultimul bloc si erau peste 10000 tranzactii neprocesate.
Acum nu pot sa demonstrez pentru ca se gasesc mai repede blocurile.

Later edit: hai sa luam blocul 373130: https://blockchain.info/block/000000000000000009367ecf9f6afe6a0d9a3d4a0c220a8369b24056694aa638
A fost gasit la 7 minute dupa urmatorul, care era 373129: https://blockchain.info/block/000000000000000007a402705645d5f7ced252f6ffd40ce700cc1bc096defdd6.
7*9=63 minute, 889*9=8001 tranzatii in 63 minute.
